Hello. You may call me Dr. David and I would enjoy being your tutor in English reading, writing and speaking; Pure and Applied Mathematics, including Statistics; ACT, SAT and GRE Prep; or, Physics. In the last few years, I taught and tutored students in High School, College and Graduate School. My students find me pleasant, curious and caring.

My lessons are prepared, thoughtful, lively and fun. A calm environment without distractions is ideal. Usually, I meet with students in a local library, bookstore or at home.

Each student has his or her own style and I try to match it. The best way to learn a subject is to have it presented clearly, to study class notes carefully, and to do assigned work regularly. The key to advancement is comprehension of the concepts and practice doing assignments. As I make an effort to be a good listener and prepare in advance for each lesson, if you are devoted to doing the required work we can build towards a successful outcome.

Descriptive and inferential statistics both apply to biostatistics. The former characterizes a population, often on the basis of samples. The latter involves examination of data for hypothesis testing, estimation, discovering correlations and other relationships.

In college and graduate school I studies probability and statistics as part of the standard curriculum in physics and mathematics. At work, I have used and continue to use statistics in the engineering projects I work on. The areas I have specialized in are probability distributions, conditional probability, sampling, regression, confidence levels, analysis of outliers and hypothesis testing.

Differential Equations

In college and graduate school I studied the classical treatement of ordinary and partial
differential equations, including

• Newton's 2nd Law
• Radioactive decay
• Heat Equation
• Wave Equation
• Maxwell's equations
• Laplace's equation
• Poisson's equation
• Einstein's field equation
• Schrödinger equation
• geodesic equation
• Navier-Stokes equations
• Cauchy-Riemann equations
• Poisson-Boltzmann equation
• Elliptic Equations
• Grad-Shafranov Equation

The most extensive application I made in the work world
was for the determination and prediction of the orbital
dynamics of NASA Scientific satellites.

Nature is amenable to precise modeling by differential
equations. The analysis of differential equations is
both a beautiful subject just for the mathematics "of
it" and a useful one for describing natural events.

Discrete Math

In college and graduate school I studied linear algebra and probability theory
extensively. At that time, I did not realize that in the working world the main
application of Discrete Mathematics I would utilize was algorithms for computers.
Probability theory is a close second. Logic, set theory, combinatorics, graph theory,
information theory and computational geometry were all subjects that I developed a
working knowledge of while on the job.

Of them all, I enjoy set theory the most, perhaps because it requires deep thought.
Of them all, I find matrix algebra (of linear algebra) the most useful since it is
turns up in a wide assortment of engineering applications.

Linear Algebra

In both Physics and Mathematics courses in College and Graduate School I have studied and applied results from Linear Algebra. In my
current work in imaging I regularly refer to
fundamentals from Linear Algebra and apply both
concepts and theorems. In addition, I have
experience as a tutor for College students in this


Matlab is ideal for projects involving data as well as for general science and engineering computation. Matlab has been the main software development system I have used for nine years in projects in engineering and physics. The special areas I have worked on include modeling and simulation, statistics, and data analysis.


Both in College and at work, I have used statistics extensively.
Students I have taught in statistics have ranged from High School AP through Graduate School. The concepts are typically simple but applications can be involved. In my teaching, I
emphasize patiently thinking through a problem.
