I am a postdoctoral research assistant working in the Statistics Department at the University of Oxford under the supervision of Professor Jotun Hein (since 2006). I received my undergraduate degree, BS-Mathematics, at Santa Clara University in 2001. I received my PhD in Statistics at the University of Washington (with an emphasis in statistical genetics) under the supervision of Dr. Matthew Stephens in 2006, with my thesis on the development of a new statistical model for estimating rates of gene conversion using Single-Nucleotide-Polymorphism (SNP) data.

Research Interests

My main research interests involve applications of statistical methodology (Bayesian and otherwise) to genetics data. Presently my chief project involves the development and application of genomewide association methods and analyses, involving an international collaboration with the University of Oxford (England), deCODE Genetics (Iceland), the University of Aarhus BiRC (Denmark), and Radboud University Nijmegen Medical Centre (Netherlands). Other projects include the study of fine-scale meiotic recombination rates and inferring patterns of admixture in modern humans using genetics data.
