As an applied mathematician and a data scientist, I have more than 10 years of combined experience of teaching and tutoring mathematics to college and high school students and 10+ years of industry experience.

I received a Ph.D. degree in applied mathematics in 2013 and have instructed on a wide range of mathematical courses in various branches of mathematics including Calculus I,II, Multivariable Calculus (Calculus 3), Advanced Calculus (Calculus 4), Linear Algebra, Differential Equations, Discrete Mathematics, and Probability for the college students as a lecturer and as a private instructor. I also have taught pre-calculus, algebra, geometry, trigonometry, and elementary level math to the secondary school students. Additionally, I am teaching and helping motivated high school and middle school students to prepare for the mathematical summer camps and competition style mathematics including America Mathematical Competitions (AMC), Math League Contest, MATHCOUNTS competitions.

I always say that mathematics is an art form. Contrary to popular belief, mathematics can be one of the most creative scientific disciplines. My teaching philosophy emphasizes on providing students with a strong fundamental understanding of mathematics and giving them a considerable degree of freedom. Ultimately there may be only one correct answer to a problem, yet there are many different ways to derive that answer. That is where the fundamentals and artistic elements of mathematics come to play. Mathematics is the language of nature. It has the ability to transform students in their way of thought, who practice free and rational thinking rather than simply memorizing equations and statements.

My subjects include: AP Calculus AB, AP Calculus BC, Calculus I,II,III,IV, Probability,College Algebra, American Mathematics Competitions, Differential Equations, Discrete Mathematics, Geometry, Linear Algebra, Probability, Pre-Calculus, SAT Math, SAT Math Subject Test.

Amazing!

He helped me during the summer for my Calc 2 10 week course. I was struggling a lot in the beginning & decided to get a tutor. He was very patient with me & helped me get ready for the final and helped me pass 2 tests. The class was online, so I had a hard time understanding the concept and he helped me throughout the entire summer. I was able to finish the class with an A. I 100% recommend if your struggling in any math college courses.

Excellent tutor!

Timothy is an excellent tutor for a Calculus III (college level). Not only did he obviously have a solid knowledge of the material, but he was very helpful in explaining details. Timothy was also very flexible in arranging the schedule, which was very much appreciated.

Knowledgeable and caring

It’s been hard to find a tutor who can dive in to the graduate level data science materials for my courses. I like to understand concepts in a fundamental ways and a lot of times, I just receive answers that discourage me from digging deeper from the TAs. So, I sought out tutors who can work with linear algebra, calculus, statistics and probability all in the intermingled models of data science course materials. Timothy is a tutor who can explain these models from the concepts all the way through the mathematical building blocks and to the applications of them. I cannot recommend him more!

Knowledgeable and patient tutor - top notch!

Tim worked with my daughter on Calculus II. He was not only knowledgeable about the subject, he understood how to teach. This combination is hard to find. Thank you Tim!

Beth , 43 lessons with Timothy

He is an excellent tutor

My son got many supports as he needed. He grasp his way of tutoring very fast and well. He has great desire to teach students who really looking help. I know Mr. Timothy is very busy, but he never mind accept any questions student has!

Mohan, 3 lessons with Timothy

Extremely efficient

A top-notch tutor! He is very passionate about tutoring and highly efficient with postgrad level math tutoring. Thanks, Dr. Timothy L. ! I will be in touch again as I navigate my Master's program.

Kurt, 8 lessons with Timothy

Knowledgeable, clear and thorough

Timothy taught my daughter circular functions, something she was struggling with. His explanations were very clear, and Timothy took the initiative to teach beyond the question asked (which not all tutors do.) He made sure he covered all the points my daughter would need to master the topic. The next day after the session with Timothy, my daughter had her quiz and feels very confident that she did really well. We are very happy we found Timothy.

Great tutor!

Timothy was very helpful with the calculus 3 concepts that I have been struggling with. I would highly recommend Timothy for any advanced math tutoring needs.

Kathy, 9 lessons with Timothy

Excellent Tutor!

Timothy really helped me understand my notes from class, he explained the theory behind Taylor series as well as shown me some easy examples before moving on to the more difficult examples. He is excellent at breaking things down and I would highly recommend him as a tutor.
