About Robert

Dear Prospective Student and Parent:

My goal before I retire is to obtain for my students >$30,000,000 dollars in scholarships. I am continuously looking for students in Engineering, Science, Mathematics, with a smaller number of selective students in Medicine for 7 year medical programs. I attended advanced institutes for 11 years of education and have collaborated with most of the major pharmaceutical companies on a variety of projects.

I am looking for college students who would like to go to graduate school on scholarships. Graduate scholarships can range from $100,000 to $1.5 million.

My routine tutoring is in the area of first and second year college with average scholarships with interest is approximately $240,000 per student.

I have decided to begin teaching elementary schools students to help prevent the further decline in the United States in mathematics and science. Currently, the United States is 29th in the world in science and 22nd in mathematics. Furthermore, this decline has occurred in less than 20 years and it is actually getting worse. I urge parents to help their children by hiring expert in science and mathematics.

My educational background is in advanced science and mathematics with having completed the equivalent of three different Ph.D. level projects in Chemistry, Physics, and Biochemistry. I am now working on a fourth Ph.D. equivalent project in advanced mathematics related to industrial and manufacturing processes that has enormous academic research potential for thousands of scientists and engineers.

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

ACT Math

The ACT mathematics is an examination that needs to be developed with consistency and clarity in conjunction with the students normal classes in science and mathematics. Science and Mathematics on the ACT can be developed more easily than that for the SAT (even though my students obtain perfect scores on the SAT). Proper guidance and logic are the main aspect that I stress when I am tutoring/teaching/training individuals of all ages.

The primary problem for students to overcome on both examination is the lack of rigorous algebraic drills.

Dr. Bob

ACT Reading

The fundamentals of electrical and mechanical engineering are based on physics, chemistry, and mathematics related to instrumentation designed by chemists, physicists, and advanced technicians. The symbols for electrical engineering are used in most of the advanced classes in chemistry, physics, and mathematics related to engineering.

My focus is on the basic engineering courses that utilize my education in advanced physics, mathematics, and science.

Dr. Bob

ACT Science

The ACT examination covers many topics.

In my tutoring I focus on many advanced concepts related to human health and disease prevention for the promotion of healthier life. The overview of my science teachings is geared for improving life on our planet while trying to have students understand homeostasis for not only us, but all living organisms.

The ACT covers some major topics in environmental chemistry that may directly related to bioavailability of nutrients (biotic and abiotic) necessary for sustaining these life processes.

TABLE 1-1 Definitions of “Bioavailability” and Related Terms



A chemical element is bioavailable if it is present as, or can be transformed readily to, the free-ion species, if it can move to plant roots on a time scale that is relevant to plant growth and development, and if, once absorbed by the root, it affects the life cycle of the plant.
Sposito, 1989

Generally used to describe the extent and rate of absorption for a xenobiotic which enters the systemic circulation in the unaltered (parent) form from the applied (exposure) site.
Hrudy et al., 1996

The availability of a chemical to an animal, plant, or microorganism. It may be assayed by measurement of uptake, toxicity or biodegradability.
Linz and Nakles, 1997

A concept that describes the ability of a chemical to interact with living organisms.
NEPI, 1997

The accessibility of contaminants to microbes from the standpoint of their metabolism, their ability to grow on these chemicals, to change cellular physiology, and perhaps modulation of genetic response.
Sayler et al., 1998

A measure of the fraction of the chemical(s) of concern in environmental media that is accessible to an organism for absorption.
ASTM, 1998

A measure of the potential for entry into ecological or human receptors. It is specific to the receptor, the route of entry, time of exposure, and the matrix containing the contaminant.
Anderson et al., 1999

The extent to which a substance can be absorbed by a living organism and can cause an adverse physiological or toxicological response.
Battelle and Exponent, 2000

Bioavailable: For chemicals, the state of being potentially available for biological uptake by an aquatic organism when that organism is processing or encountering a given environmental medium (e.g., the chemicals that can be extracted by the gills from water as it passes through the respiratory cavity or the chemicals that are absorbed by internal membranes as the organism moves through or ingests sediment). In water, a chemical can exist in three different forms that affect availability to organisms: (1) dissolved, (2) sorbed to biotic or abiotic components and suspended in the water column or deposited on the bottom, and (3) incorporated (accumulated) into the organisms.
EPA, 2000a

The fraction of an administered dose that reaches the central (blood) compartment, whether from gastrointestinal tract, skin, or lungs. Bioavailability defined in this manner is commonly referred to as “absolute bioavailability.”
NEPI, 2000a

Algebra 1

Algebra in my view is the fundamental mathematics for all of science and the majority of economics, statistics, and advanced calculus.

In being an expert in the teaching of Algebra,my teaching will save students many hours(days) as well as saving them from the anxiety of quizzes or examinations as well as lost time. Also, as you develop your techniques we will begin to minimize issue of stress that in the majority of high school cases will become non-existent.

Dr. Bob

Algebra 2

I have taught several thousands students algebra and I am currently writing a book for advanced algebra problems.
Dr. Bob


I have been teaching medical students for more than 20 years and have had a tremendous success at decreasing medical errors when they become physicians. It is clear that medical students are requiring more effort in tutoring and personalized education. I connect anatomy to physiology to biochemistry.


I was a former Tax Examiner for the IRS and went through their entire training system.

In my business endeavors, I spend time with many individuals who are experts in Tax systems at the local, state, and federal level.

I believe that good businesses should have proper legal definitions with an emphasis on National Debt Reduction.

Dr. Bob


My primary emphasis in teaching autocad is to develop the programming methodology behind autocad or computer programming modules.

Advanced Analytical geometry, coordinate vector analysis, matrix systems with advanced algebra, calculus, and mathematical relationships are all used.

I am teaching several elementary, high school, and college students the fundamentals of autocad design programming.

Dr. Bob


I have been teaching and tutoring biochemistry for health and nutrition for more than 20 years. My patents at the United States Patent and Trademark office are some of the most advanced biochemistry applications in the world. Please read the patents at the USPTO for a completely understanding of the interrelationships between microbiology, biochemistry, organic chemistry, and spectroscopic techniques for studying proteins, DNA, RNA, peptides, and millions to billions of other molecular entities. The biochemistry class that I have developed for tutoring allows students to not only understand biochemistry, but endocrinology with advanced applications to the kinetics and thermodynamics of pharmaceuticals and drug metabolism issues.

The information contained in the patents can only be understood by the most sophisticated biochemists.


I have been teaching biology, earth science, and biochemistry for more than 20 years with at least one class of microbiology every year. Food, Water, and Energy are my primary strengths related for biochemical related concepts of metabolism and respiration.

Photosynthesis is a fundamental process that I teach on a yearly basis that starts the biothermodynamics for all life on the planet.


Botany is the scientific study of plants. It was established as a science in early classical times when Aristotle and his pupils designed a systematic approach to studying and classifying plant species. There are many disciplines defined in modern botany, including many plant biology specialties and a variety of applied plant sciences. I am currently teaching botany to most of my biology, MCAT, and related students. Then to many of the Wyzant students as part of natural science philosophy.

I am an avid horticulturist, botanist, chemist, who has been teaching botany for the last ten years while teaching environmental chemistry, botanical nomenclature, environmental remediation, and other earth science related courses. True botany is one of the most difficult classes to teach due to the logical organization and colloquial nomenclature that transcends the entire span of human existence.

The first medicines by Galen, Aristotle, Hippocrates, and in the written record, the study of botanical herbs dates back over 5,000 years to the Sumerians, who described well-established medicinal uses for such plants as laurel, caraway, and thyme. Ancient Egyptian medicine of 1000 B.C. are known to have used garlic, opium, castor oil, coriander, mint, indigo, and other herbs for medicine and the Old Testament also mentions herb use and cultivation, including mandrake, vetch, caraway, wheat, barley, and rye.

My passion in botany is in the area of orchids. Orchid family is also known as Orchidaceae, commonly referred to as the Orchid family, is a morphologically diverse and widespread family of monocots in the order Asparagales. It is currently believed to be the second largest family of flowering plants (only the Asteraceae is larger), with between 21,950 and 26,049 currently accepted species, found in 880 genera.[1][2] The number of orchid species equals more than twice the number of bird species, and about four times the number of mammal species. It also encompasses about 6–11% of all seed plants.[3] The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species).

The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus) and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.
Reference Societies:
The Society of Rheology is composed of physicists, chemists, biologists, engineers, and mathematicians interested in advancing and applying rheology, which is defined as the science of deformation and flow of matter.

The Earth is host to more than several million documented species of plant life. In turn, our planet depends upon these plants to nurture and sustain all living things. Plants play a critical role in the complex food web. Powered by light from the sun, carbon dioxide from the air, and nutrients from the soil, plants pass on this energy to the life forms that consume them. And for the human species, plants bring aesthetic pleasure, delighting the senses with their beauty and variety.

Botany is one of the oldest branches of biology. It is concerned with the scientific study of plants and other similar organisms. Within the discipline there are many areas of study including Paleobotany (the study of plant history through fossils), Physiology (the study of plant cells and tissues), Pteridology (the study of ferns), and Plant Pathology (the study of diseases in plants).

The History of the Calculus and Its Conceptual Development: By Carl Benjamin Boyer

Calculus and Advanced Mathematics is a critical feature of modern society, unfortunately we have not properly (in my opinion) learned how to teach it.

My background and teaching methodology is unique for the teaching of mathematics, but also calculus. With proper time and effort all my students perform with significant grade enhancements and significant less stress.

I am always looking for new entrepreneurs who want to improve their fundamental development of business mathematics.

Dr. Bob

Career Development

During my extensive teaching and lecturing to many diverse populations, I have developed experience at moving individuals from one career to another. With my expertise I have been told by my clients and students that the transition had been less stressful than they had imagined due to my advice and counseling. My expertise has also saved many of my clients and students needless expenditures.

Education is an ongoing process, and I believe that foreseeing the possibility of wasted time and energy on insignificant issues or hurdles is where my strengths benefit my clients.

During my career in teaching I have taught students for the following transition examinations:
SAT, ACT, SAT II, NYS Regents Exams, AP Exams, TAKS Exams, College entrance exams, GED, ESL Exams, GRE, LSAT, NCLEX, MCAT, and many other board certification exams.

Please consider me for your career transition advisor. I feel that I will be able to make this experience as beneficial as possible.

Chemical Engineering

My experience in chemical engineering is significant in that I have worked with Chevrolet, Mobil, Exxon, Johnson & Johnson, Merck, Pfizer, and various German manufacturing companies related chemical kinetics and industrial chemistry. My specialty in chemical engineering is related to stoichiometry a chemical hazards with an emphasis on thermodynamics and pressure equations for phase diagrams. Thank you Dr. Bob


My expertise in teaching advanced chemistry has earned students perfect scores on SAT II science examinations. Furthermore, most of my students generally improve two grades at a minimum over a 5-6 week tutoring program for their college or university courses. My emphasis is on reaction mechanism for the most advanced students.

My expertise in teaching the MCAT's and microbiology related concepts that are integrated with organic and biochemistry is becoming a unique academic subject by itself, while I am tutoring.

I suggest students who want to be M.D.'s to have some extra help starting in the fourth or fifth grade, while improving their mathematics skill level.

Dr. Bob

Differential Equations

My six courses in physics related to Magnetic Resonance Imaging (MRI) and my last three mathematics courses all dealt with advanced differential equations.

The most interesting course that contained differential equations was my advanced course in Advanced Thermodynamics and Kinetic Isotope Separation.

Discrete Math

I have been teaching discrete mathematics for more than 20 years at a variety of levels. My Ph.D. and patents in chemistry, biochemistry, and physics are based upon advanced mathematics related to discrete mathematics and topological functions.


I have recently started a new business related to corporate training, small business development, and economics. The current economic systems that I currently teach are from the High School level to first or second year college classes.

A key area of my teaching specialty related to my advanced mathematics is in the area of interest rate fluctuations as well as logistical and distribution cost systems than can cause businesses to be profitable or migrate towards bankruptcy.

Divergent areas related to the construction, transportation, architecture design, food production, and implementation of natural systems are a consistent theme in the economic and advanced business integration systems that I am working on.

Wall Street has some clear examples such as Wonder Bread, Hostess, and a myriad of others that are now near or in bankruptcy.

Some simple concepts that are normally taught as part of business economics are:

Economic Terms
Business Calculus
Matrix Theory
U.S. Census
Population, Health,
National Orphan and Rare Diseases
Energy Data Information
International Government Websites

I have taught several thousand students elementary school science and mathematics. If you would like to have your son/daughter have consistent grades, please contact me. I prepare my students for college using consistent, logical, and clear progressive mathematics and science.
Dr. Bob


Geometry is the basis of life. The simplest form of matter such as quarks, leptons, gluons, electrons, protons, and neutrons all have geometric shapes that allow each individual atom to have unique properties. These properties allow life to exist and are fundamental to the diversity of life.

My specialization in geometry and trigonometry is related to the development of a specialized area of science that is called the Calculus of Biology and Chemistry from the Fundamental of Geometry and Trigonometry.

A majority of my students excel in geometry and trigonometry under my tutelage.

Dr. Bob


I have decided to begin a intense tutoring in reading, writing, and communication skills for students. This includes compositions for entrance examinations and application letters for University and colleges around the world. My focus is to develop students to become sophisticated writers, editors, with a passion for expression that is the cornerstone of our civilization. Documents such as the Declaration of Independence have now been somewhat forgotten in a world that is in turmoil. History will be taught to help improve vocabulary and spelling.

Linear Algebra

These more advanced courses are primarily taught by math and science experts at the University. My background in linear algebra is significant due to my advanced science related to my research endeavors in advanced science systems. Linear Algebra also used differential equations.


Logic is normally part of my teaching system in advanced mathematics courses. Logic, tree diagrams, Logic circuits (engineering), dendrimers, and other advanced science is part of my repertoire of teaching methods. Please add this certification to my account.

I have taught Logic systems for more than twenty years, including setting up one of the first comprehensive department wide computer network using logic diagrams and logical connections. I have just finished teaching three students logic sections for the SAT, GMAT, and GED.


I am a sophisticated instructor of advanced science courses with all the complementary mathematics. I can give students skills to generate scores in the 99th percentile. Organic chemistry is a simple subject when I teach it, although it has a voluminous amount of information. I suggest 2 hour sessions twice a week for six weeks for most students.

Dr. Bob


My experience in Microbiology is based upon teaching hundreds of students the fundamentals. Microbiology is one of the oldest sciences because it is directly related to food. Few individuals today understand the history of microbiology and its impact on chemistry, food, nutrition, and human health.

Experience in microbiology biology can significantly decrease STD's and many other negative health consequences for children and adults.

Key topic areas that I teach are related to: bacteria, diseases, and prevention of sickness. It is clear with the large amount of birth defects and hospitalizations and the catastrophic STD rates in cities that a more clear and pronounced teaching is necessary for students and adults.

My emphasis is towards prevention of diseases such as Ebola using advanced Physics, Chemistry, Biology, Biochemistry, and Mathematics to teach students and Medical Doctors how to minimize negative health occurrences.

Dr. Bob


I have been teaching the NCLEX examination for more than 20 years to a variety of students. My teaching at the University was geared specifically toward Nursing and ACCEPTED Medical Students.

Microbiology, Biochemistry, Physics, Chemistry, Organic Chemistry are the primary systems that I focus on.


Dear Sir:

I have been teaching nutrition students for more than 20 years since I was a Professor in New York teaching nutrition, chemistry, and biochemistry. My major area of concentration is that regarding molecular nutrition and components related to the development of healthy fetuses. The National Academic Press has many books that I have read on micronutrients and macronutrients. In having taught the MCAT similarly for more than 20 years, I normally emphasized advanced molecular nutrition components related to biothermodynamics and equilibrium systems related to isomers. It is clear that many components of nutrition are being lost in the new curriculums. I am working with the USDA on the development of new material for teaching nutrition for adaptive learning processes using advanced semantic models and logic processes.

Dr. Bob

Organic Chemistry

I have taken more than 10 classes related to Organic Chemistry and have attended at least 1,000 hours of advanced lectures. My GPA in Organic Chemistry is a 3.4 at the Graduate School Level. All the organic classes were Honor classes with advanced training.

Physical Science

I have taught tens of thousands of students advanced physical science with an emphasis on understanding soil, rocks, minerals, and the fundamentals of geology, chemistry, biochemistry, and physics. A heavy emphasis is placed on mathematics, especially related to pH, Temperature, and solubility properties.

Physical Science is the foundation of Construction, Engineering, Architecture, Geology, Physics, Chemistry, Botany, Biology, and is crucial to our economy.

Dr. Bob


My background in Physics dates back to 1976, when I began looking at how fireworks could be designed with mathematical equations and complex physical parameters. In high school I built rockets and wrote computer programs to calculate trajectories. During college, I excelled in laboratory and experimental design systems with an advanced knowledge of inverse photoemission and surface science related advanced physics.

I currently specialize in teaching the physics of fundamental kinematics and advanced physics topics, especially related to quantum mechanics and light equations.

Dr. Bob


The fundamental mathematics of everyday living is based upon prealgebra. I firm, logical, and clearly organized mathematics teaching program that I offer not only will allow a student to excel, but will allow them to have a reduced school anxiety and stress level.

My main focus in teaching prealgebra is to develop a consistent and stress-free approach to mathematics and science.

Dr. Bob


Precalculus is the fundamental mathematics necessary for the SAT, ACT, and other core subjects in science and mathematics. My approach is very rigorous with a focus on College Algebra and techniques related to basic business mathematics. The future of business is based upon this one class and how it is applied to economics.

Dr. Bob


I am interested in proofreading theses in the following areas: history, mathematics, science, and political science. My interest in proofreading is primarily to help develop more logic to how information is presented with a consistent theme.

Dr. Bob


Reading is a critical feature of our culture. I am developing a coordinated technology group to help improve reading and history. I normally teach students for many years.

SAT Math

My ACT/SAT Math/English qualifications is geared towards improving students scores by 300-400 points on the SAT and 4-6 points on the ACT.

My primary focus is to improve students skill sets so they can survive at the University without causing hundreds of thousands of dollars in debt, while decreasing their stress levels.

SAT Reading

I have been teaching SAT/ACT mathematics and related English topics for more than twenty years. I have had SAT score increases of 400-500 points in the most extreme cases, while in others 50 to 150 points a common increase. I focus on advanced fundamentals that allows the student to pass college classes also.

I SPECIALIZE in the SAT II examinations and the Advanced Placement Examinations.


Statistics is the mathematics of the collection, organization, and interpretation of numerical data, especially the analysis of population characteristics by inference from sampling.

My knowledge of statistics is useful in my development of my corporate business related to Health, Society, and Cultural Trends.

I use OSHA, National Cancer Institute (NCI), EPA, and other health and safety systems to analyze statistics for the DFW region, but also for National or International trends.

Some Key terms from the NCI

age-adjusted rate
An age-adjusted incidence or mortality rate is a weighted average of the age-specific incidence or mortality rates, where the weights are the proportions of persons in the corresponding age groups of a standard million population. The potential confounding effect of age is reduced when comparing age-adjusted rates computed using the same standard million population.

annual percent change (APC)
Annual Percent Change is used to measure trend or the change in rate over time. It is the "average" annual rate of change over the time series selected.

Annual Report to the Nation
An annual update of cancer death rates, incidence rates (new cases), and trends in the United States. The Centers for Disease Control and Prevention, the American Cancer Society, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate to create this report.

cancer burden
A measure of the incidence of cancer within the population and an estimate of the financial, emotional, or social impact it creates. The burden of disease is not borne equally by all population groups in the United States.

Cancer Statistics Review (CSR)
An annual report containing the most recent incidence, mortality, and survival statistics, published by the Cancer Statistics Branch of the NCI. It presents a broad profile of the cancer burden.


During the last five years I have taught several hundred students, TAKS examination material.


Trigonometry - a basic necessary for almost 75 % of all college courses in chemistry, physics, mathematics, engineering, and healthcare (MRI, PET, Cancer Chemotherapy) that use radiation or electromagnetic energy. My expertise in trigonometry covers most of the natural and physical sciences.
