# Sarah Christensen

I am currently a second-year PhD student in computer science at the University of Illinois advised by Professor Tandy Warnow. My most recent research is in the area of computational phylogenetics, where I work on developing efficient algorithms for constructing evolutionary trees from genetic sequences. I graduated from Amherst College in 2013 with a bachelor's degree in mathematics. My CV can be found here.
