Younhun (Youn) Kim
(last updated: Oct 2019)

I am a fifth-year graduate student at MIT pursuing a Ph.D. in Applied Mathematics, currently advised by Bonnie Berger. My mathematical interests lie at the intersection of Combinatorics and Statistics. In particular, I find probabilistic models and theoretical questions inspired by applications (i.e. biology) attractive. Currently, I am collaborating with Gibson Lab to develop various methods for analyzing microbiome data.

My first name is pronounced "Young Hoon", without the g. My colleagues simply call me "Youn".

General

I received a Bachelor of Science degree in May 2016 from Brown University in Mathematics and Computer Science. During my time there, I was fortunate enough to be in the company of Professors Sorin Istrail and Ben Raphael.

Prior to finishing undergrad, I was employed by Orbis Systems in Jersey City, NJ as a programmer from 2009 to 2013.

Miscellany

  • I was an organizer for the MIT Simple Person's Applied Math Seminar (SPAMS) for 2018 ~ 2019. Graduate students give talks that are roughly thirty-minutes long, zero-pressure and are meant for fun and expository (applied) mathematics to be presented to a curious audience. We've hosted people from various departments, not just mathematics. Please attend or give a talk!
