Won’s journey through academia has been an interesting one, to say the least. Having graduated from TJ, Won set out to establish himself as a premier physician. Well, that clearly didn’t happen. But what’s a math major (who decided not to pursue a career in medicine after all) to do? Why, go to law school (obviously, he said, sarcastically). It makes complete and absolute sense, of course, that as a licensed (and active) member of the Virginia Bar, Won pursued teaching instead. Over the years, Won has taught math of varying levels up to AP Calculus BC, AP Computer Science A, language arts (reading comprehension, English grammar, and essay writing), and logical reasoning. Won one day hopes to write a really amazing novel.
Dr. Aman Ullah
Dr. Ullah earned his PhD in computational biophysics from Ohio University and recently accepted a tenure-track position as a Research Assistant Professor at George Mason University. He has also worked as an Assistant Professor at Northern Virginia Community College. His work on cardiac functioning has led to cutting-edge research developing novel computational algorithms to efficiently solve the large-scale stochastic models that are used to study the heart. Dr. Ullah's research involves extensive use of Markov models, reaction-diffusion equations, bifurcation theory, and numerous other nonlinear dynamics tools.
Dr. Zach VandeZande
Zach VandeZande (aka "Dr. Zach") has been teaching English and creative writing to all ages for the past ten years. He has a PhD in English - Creative Writing from the University of North Texas. He also writes and edits books. He has published two books of fiction, a book of cartoons, and an anthology of essays on postcolonial theory. He lives in DC with his fiancée and his dog. Zach loves teaching language arts because of the way his students are always surprising him with the ways they use language. Kids understand that "making sense" is an act of creation, the same way that baking bread or singing a song are acts of creation. He loves showing students the exciting, weird, and wonderful ways they can make sense with their writing.
