About Shep

Bio

Are you struggling with a mathematics or science course, or able to follow the teacher in class but unsure how to solve problems on your own? I help students understand difficult concepts, strengthen missing prerequisite skills, and approach problems with greater confidence. I tutor high-school and college students in algebra, precalculus, calculus, discrete mathematics, physics, programming, and machine learning.

Are you struggling with a mathematics or science course, or able to follow the teacher in class but unsure how to solve problems on your own? I help students understand difficult concepts, strengthen missing prerequisite skills, and approach problems with greater confidence. I tutor high-school and college students in algebra, precalculus, calculus, discrete mathematics, physics, programming, and machine learning.

I hold a Ph.D. in Physical Chemistry from the University of California, Berkeley, and an Sc.B. with honors in Applied Mathematics from Brown University. I also completed a certificate program in Bioinformatics at Stanford University, along with specializations in Deep Learning and Data Science. In addition, I bring more than 30 years of experience as a computational scientist working in mathematics, physics, scientific programming, and machine learning.

I have taught undergraduates at Tufts University and the University of Minnesota in both classroom and online settings. At Tufts, I taught machine learning and discrete mathematics and was nominated by my students for the university’s Excellence in Online Teaching Award. At the University of Minnesota, I taught quantum mechanics, discrete mathematics, numerical analysis, and programming. I have also tutored high-school students individually in algebra, precalculus, logarithms, trigonometry, and related subjects.

My teaching style is patient, interactive, and tailored to the individual student. I identify the ideas or prerequisite skills causing difficulty, explain them step by step, and connect them to concrete examples. We then work through problems together, with progressively less assistance as the student gains understanding and confidence. My goal is not simply to help students complete an assignment, but to give them the understanding and skills they need to solve similar problems independently.

Approved Subjects

Calculus

Calculus

I hold a Ph.D. in Physical Chemistry from UC Berkeley and an Sc.B. with honors in Applied Mathematics from Brown University. I have taught mathematics, physics, computer science, and numerical analysis at the university level and have used calculus extensively throughout my career as a computational scientist. I help students understand the reasoning behind limits, derivatives, integrals, and their applications rather than simply memorizing formulas. My teaching style is patient and interactive, and I adapt each lesson to the student’s background, goals, and learning style.
Computer Science

Computer Science

I have taught computer science as a Teaching Assistant Professor, including courses in machine learning and discrete mathematics. I also have more than 30 years of professional experience in scientific computing, software development, algorithm design, data science, and computational modeling. I help students understand both the reasoning behind computer science concepts and how to translate those ideas into clear, working code. My teaching style is patient and interactive, and I adapt lessons to each student’s experience, goals, and preferred programming language.
Data Science

Data Science

I have taught machine learning and data science at Tufts University and have completed specializations in data science and deep learning. During more than 30 years as a computational scientist, I applied data analysis, statistical modeling, visualization, and machine learning to complex scientific and biomedical problems. I help students understand the reasoning behind data-science methods while developing practical skills in Python, data preparation, model building, and interpretation. My teaching style is patient and interactive, with explanations and examples adapted to each student’s experience and goals.
Discrete Math

Discrete Math

I taught discrete mathematics at Tufts University and the University of Minnesota, including both classroom and online courses. My teaching covered logic, proof techniques, sets, functions, relations, combinatorics, graph theory, recurrence relations, and mathematical induction. I help students develop the reasoning needed to construct proofs and solve unfamiliar problems rather than simply memorize procedures. My approach is patient and interactive, with explanations and examples adapted to each student’s background and goals.
Linux

Linux

I have more than 30 years of experience using Linux and Unix systems for scientific computing, software development, and data analysis. I can help students learn the command line, navigate and search file systems, manage files and permissions, work with processes, and write shell scripts. I also have extensive experience with scientific programming and computational workflows in academic and industrial environments. My teaching approach is patient and hands-on, helping students understand each command and develop the confidence to solve problems independently.
Machine Learning/ AI

Machine Learning/ AI

I have taught machine learning at Tufts University and have completed specializations in data science and deep learning. During more than 30 years as a computational scientist, I applied data analysis, statistical modeling, visualization, and machine learning to complex scientific and biomedical problems. I help students understand the reasoning behind data-science methods while developing practical skills in Python, data preparation, model building, and interpretation. My teaching style is patient and interactive, with explanations and examples adapted to each student’s experience and goals.
Physical Science

Physical Science

I hold a Ph.D. in Physical Chemistry from UC Berkeley and an Sc.B. with honors in Applied Mathematics from Brown University. I have taught university-level physics, including quantum mechanics, and have more than 30 years of experience applying physics, chemistry, mathematics, and scientific computing to real-world problems. I help students understand topics such as matter, energy, forces, motion, atomic structure, and chemical reactions by connecting equations to physical intuition and everyday examples. My teaching style is patient and interactive, and I adapt each lesson to the student’s background and learning goals.
Physics

Physics

I hold a Ph.D. in Physical Chemistry from UC Berkeley and have extensive training in physics, mathematics, and scientific computing. I have taught undergraduate quantum mechanics at the University of Minnesota and have more than 30 years of experience applying physics and mathematics as a computational scientist. I can help students with mechanics, electricity and magnetism, waves, optics, thermodynamics, and modern physics. My teaching style emphasizes clear explanations, physical intuition, and step-by-step problem-solving.
Precalculus

Precalculus

I hold an Sc.B. with honors in Applied Mathematics from Brown University and a Ph.D. in Physical Chemistry from UC Berkeley. I have taught mathematics and other quantitative subjects at the university level and have tutored high-school students individually in precalculus, algebra, logarithms, trigonometry, and related topics. I help students connect equations, graphs, and underlying concepts so they are well prepared for calculus rather than relying only on memorized procedures. My teaching is patient and interactive, with lessons tailored to each student’s current understanding and goals.
Quantum Physics

Quantum Physics

I hold a Ph.D. in Physical Chemistry from UC Berkeley and have taught undergraduate quantum mechanics at the University of Minnesota. In that class, I focused on wave functions, the Schrödinger equation, operators, uncertainty, angular momentum, tunneling, and atomic structure. I help students connect the underlying physical ideas with the linear algebra, calculus, and differential equations used to solve problems. My approach is patient and step-by-step, with an emphasis on building both intuition and mathematical confidence.
