I have my own freelance mathematical modeling company, and teach part-time at a university, in an applied mathematics department. I have taught mathematics for over 12 years, at all levels - including courses in algebra, pre-calculus, calculus, linear algebra, differential equations, and numerical methods. I have worked in a variety of academic and industry positions, focusing on applied and computational mathematics, with applications ranging from environmental modeling, molecular modeling, and systems biology modeling. I have also tutored students in subjects ranging from algebra through calculus.
