I'm a recent graduate of Columbia University and hold a MA in Statistics (2014) and a BA in Biochemistry (2012). I am currently a first year medical student in the UC Berkeley-UCSF Joint Medical Program. I've spent the last two years helping students part-time in NYC in subjects ranging from chemistry to SAT prep. As an undergraduate I TA'ed introductory physics for undergraduate engineering students.

My philosophy to tutoring and teaching is to emphasize problem-solving skills over rote memorization. I believe that teaching and reasoning through problems enables students to develop critical thinking skills that extend beyond the classroom. By learning multiple approaches to problems, one gains the knowledge base to master a particular subject, alongside creative and abstract reasoning skills that are essential to personal and intellectual growth.

I am available to help high school and undergraduate students in math (algebra, geometry, trig, pre-calc, SAT), statistics and probability, and general chemistry and physics.

I saw in him the desire to help others. Such a humble, patient, and trustworthy tutor. He really knows how it feels to be left behind or to not understand a concept, and he presents a positive approach about student’s concerns. I appreciate his words "you can still make up your grades from the remaining weeks of the class". It gave me confidence and the motivation to continue working hard. I’ll always recommend him.

Dan is a excellent tutor with a great attitude when teaching, his style of teaching is very effective and makes use of the given time to the fullest. Also the way he teaches gets straight to the point, and topics can be learned very quickly. Definitely have seen improvements in my school work with Dan's help. He is also very quick to reach by phone or e-mail.

I needed a tutor at very short notice and Dan got back to me right away. He maintained excellent, professional communication through out our correspondence, and he even contacted me when he had a cancellation because he knows how much help my child needs. The tutoring session went very well and was definitely beneficial for my child.

Dan was very gentle, polite and well prepared about the lesson. Before starting the lesson, he send the material test sample so that my daughter can preview. He explained the concepts very exactly and easy to understand. Dan is very smart and faithful teacher. I am sure that he can be a big help to my daughter's AP chemistry. I am lucky to have a tutor like Dan.

Approved subjects are in **bold**.

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.

Linear Algebra (LA) is the study of systems of equations. Specifically LA teaches an approach to solve complex, multivariable equations, starting with an approach called Gaussian elimination. There is a more abstract way of thinking about systems of equations embodied in the notion of vector spaces, which can be thought of as an extension of the euclidean plane into multi-dimensional spaces. LA has a lot of practical applications including statistics, computer science and probability, so a deep knowledge of LA can go a long way. Understanding LA requires some basic mathematical thinking (solving systems is nothing more than doing simple arithmetic and algebra) - past this there is a lot of abstract mathematics in thinking about how systems of equations take on a spatial meaning.

I've studied Linear Algebra formally (I took it in college my senior year and received an A in the course) and have been exposed to different applications of Linear Algebra in my MA studies at Columbia in various statistics and computer science courses. As a biochemistry student in college I used LA extensively to solve problems in quantum/physical chemistry.
