Pranjal Vachaspati

I am currently a PhD student at the University of Illinois at Urbana-Champaign. I work in Prof. Tandy Warnow's group, where I study computational phylogenetics; that is, the construction of evolutionary trees from genetic sequences.

I graduated from MIT in 2014 with a bachelor's degree in physics.

I live in Urbana, Illinois. In the past, I have lived in Shaker Heights, Ohio; Princeton, New Jersey; and Cambridge, Massachusetts.

You can find the latest copy of my resume here.

I put some of my personal and class projects on my github or on my projects page, although both these pages might be incomplete and out-of-date. You can also follow me on Twitter at @ProbablyPranjal.
