I am a Yale-trained Ph.D. with over 10 years of experience teaching and doing interdisciplinary science research.
Yes, I actually have publications involving most of the subjects I tutor in.
I am fond of using analogies to make students comfortable with unfamiliar subjects, and I make every effort to get my students to truly understand the subject they are studying. I encourage questions, and if you don't bring your own questions, I will ask you questions to test your proficiency.
I am a PhD Computational Scientist with considerable experience in writing custom scientific software. Over the course of my career thus far, I estimate that I have written approximately 20,000 lines of C code, including two large data analysis packages. I have experience training graduate students in C programming, and can certainly help anybody learning C at the beginning to intermediate level.
I have been a user of Mathematica in the context of scientific research since the early 1990s, and have a very strong understanding of the fundamentals of the software and how to use it to solve mathematical and data analysis problems. I can help anybody who is struggling with the learning curve of this powerful but sometimes confusing behemoth of a computer program.
I am a PhD Computational Scientist, and in the course of my research I have written hundreds of Perl programs to solve computational problems. I have an excellent knowledge of the language, and I have experience training graduate students to program in Perl.
