USC STEM Tutor: Math, Physics, Programming, & More!

Hi there! I am a computational physicist at USC, doing research in quantum optics and solid-state physics. I teach all levels of mathematics, as well as introductory and college-level physics and various programming languages, including Fortran, Mathematica, and MATLAB. My tutoring methods are patient and adaptive to all types of students. I have tutored students of nearly every age and educational level for several years now, and I am usually available for one-on-one tutoring during the we... [more]

Algebra 1

Acquiring two degrees in physics has yielded a mastery of algebra. This entails expertise in various algebraic techniques when it comes to problem solving.

Algebra 2

I have had experience in tutoring and teaching algebra at the elementary school level, high school level, and even undergraduate college level.


I've been using calculus for well over a decade at this point, both in an academic as well as professional setting. Calculus is one of my most requested subjects (and integral to any hard science at an advanced level, pun unintended), so I've had plenty of experience successfully tutoring many students over the past several years.


I received a 5 on the AP Chemistry exam, and I have a thorough understanding of the subject. This includes a mastery of the properties and trends of the periodic table (including at the level of physical chemistry), any and all problems involving stoichiometry, thermodynamics, and reactions. I have also tutored several students in Chemistry, which significantly helped them prepare for upcoming exams in their class.



A rather sizable component of my primary profession requires a mastery of grammar (namely, when writing scientific papers that are worthy for publication in top journals). I have been proofreading essays and papers written by my peers ever since I can remember (early elementary school), and I find immense satisfaction in correcting and optimizing any and all drafts. This, combined with my passion for education, has enabled me to develop and teach systematic methods for achieving optimal writing styles.

Microsoft Excel

I have used and worked with the Microsoft Windows operating system since 1995 (Windows 95). I have worked with every version of Excel since then to perform calculation and produce professional plots, as well as using Excel file types with other programs (such as MATLAB).

General Computer


I'm currently (and successfully) tutoring other students in geometry, which focuses on utilizing a variety of postulates and theorems to complete proofs and solve for unknown variables under the constraint (or sometimes lack of constraint) of given assumptions.

Microsoft Word

I have worked with every version of Word since Windows 95, and regularly utilize Word 2016 to write papers and convert back and forth to PDF.


I am qualified to tutor in physics for various reasons. I have several degrees in physics (B.S. in Engineering Physics and an two M.S. degrees in Applied Physics and Quantum Optics), and I'm currently working towards a PhD in Physics. I've taught various lab courses in physics, as well as worked as a TA for physics courses ranging from the high school level to the graduate school level. Finally, I have been tutoring physics to other students since I began learning physics several years ago in high school.

Microsoft PowerPoint

I have used every version of PowerPoint since Windows 95 to produce presentations for a myriad of applications, including for academic, social, and professional purposes.


I have tutored the basics of mathematics (arithmetic) to students of all ages, including high school and college students. Prealgebra essentially covers the most crucial basics required for Algebra 1 and 2, such as the concept of functions, or solving for a single unknown (given an equation).


While the specific topics covered in Precalculus tend to vary from teacher to teacher (and more so from school to school), they are all important for more advanced courses in Mathematics. I have tutored several students in Precalculus, and whenever possible (if appropriate), I'll go above and beyond by explaining the principles involved in each and every topic in Precalculus, as well as how they might be used in later math courses.



Solving equations involving inverse trigonometric functions are easily some of the problems that a majority of students have the most difficulty with, typically due to their non-intuitive properties (and some teachers fail to properly explain the connection between trigonometric functions, inverse trigonometric functions, and the unit circle). With years of experience in teaching trigonometry, I have amassed a collection of approaches towards difficult topics such as these in the subject of trigonometry, which enables me to adapt my teaching style to my students' needs.


As an avid debater and author of scientific papers, I place immense value in good writing to get points across in powerful and efficient ways. This begins with a mastery of grammar and spelling, naturally, but having a diverse vocabulary can make a significant impact on the efficacy of any given piece. These are some of the principles I try to teach students as they learn and practice essay composition as well as general writing skills.


As a native speaker of English who proofreads and writes on a nearly daily basis, I place great emphasis on spelling and grammar. Naturally, this requires an understanding of the "anatomy", so to speak, of the modern English language, which is what I teach all of my students (including foreign friends) whenever speaking and/or writing is involved.


SAT Math


In addition to achieving a perfect score on the mathematics section of the General GRE, I have tutored multiple students in the past, which helped them improve their scores and get into their target graduate schools. My methods focus on inducing progress in both accuracy and speed in my students.


ACT Math

I have tutored a myriad of students in standardized tests (SAT/SAT II, GRE, ACT), with an emphasis on the mathematics and science portions. All of my students have improved as a result, and several were accepted into their choice schools as a result.

Elementary Math

I have tutored the basics of mathematics (arithmetic) to students of all ages, including elementary math. I have several years of experience when it comes to addressing the needs of all students (regardless of age) when it comes to fortifying their core understanding of basic operations and elementary math in general.

Elementary Science

I've been professionally (and successfully) tutoring STEM subjects (namely, math and science) for many months at this point, including helping students in elementary school design and construct science fair projects, all the while teaching them the core tenets of good scientific philosophy and how to differentiate between theories, laws, facts, hypotheses, as well as different forms of science (e.g., observational, empirical, theory/experiment, etc) and how to classify bodies of knowledge.

Computer Programming

In addition to having taken several programming courses in my physics career, I have worked with and created several programs in C, C++, Fortran, MATLAB, Mathematica, and Python. In addition to such experience, besides incorporating basic structures like for loops, while loops, multi-dimensional arrays, I have also developed techniques to optimize the programming structure in most of the simulations I create.


I have used MATLAB since 2008, when I taught myself to numerically solve differential equations to study tokamak plasmas. Since then I've used it extensively for a variety of models and simulations, including producing professional scientific figures and animations to boot. I continue to heavily rely on MATLAB for my current research, as it contains many convenient features. In addition, I have generated various template m-files which could come in quite handy for creating new programs or for teaching purposes.

Microsoft Windows

I have used and worked with the Microsoft Windows operating system since 1995 (Windows 95). Since then, I have had extensive experience in using and navigating through Windows ME, Windows XP, Windows Vista, and Windows 7, which is the latest (and in my opinion best) operating system to be released by Microsoft, and the OS I primarily use everyday.


I have utilized Mathematica throughout the extent of my undergraduate education. In addition, I heavily relied on Mathematica for analytic calculations while obtaining my M.S. degree. Such experience has yielded a broad mastery of the program's various built-in functions and features. I have generated various template notebook files which could come in quite handy for creating new programs or for teaching purposes.
