Titles

Assistant Professor, Cornell University

I am a population geneticist and computer scientist interested in leveraging large scale genetic data to understand human genetic history, evolution, and the genetic basis for human disease. My work focuses on developing computational methods to process large scale genetic datasets and on performing analyses of genetic data using my own and other software. I am interested in inferring haplotypes and understanding their evolution by recombination and mutation. In so doing, I aim to help reconstruct the ancestral recombination graph of humanity; i.e., the genealogical tree at each genomic position that relates human beings to each other.

I am currently a Postdoctoral Research Associate working with Molly Przeworski at the Howard Hughes Medical Institute (conducting work at Columbia University). I received a PhD (2010) and SM (2005) in Computer Science from Massachusetts Institute of Technology, and two BS (2003) degrees in Computer Science and Mathematics from the University of Utah. From 2009-2013 I worked as a Postdoctoral Research Fellow with David Reich and David Altshuler at Harvard Medical School.

Starting August, 2014, I will be an assistant professor at Cornell in the Biological Statistics and Computational Biology department. Job openings for a programmer and postdoctoral fellow will be posted soon! Send your CV if interested.
