Research and Personal Info

I am a postdoc studying the genetic diversity and population structure of Miscanthus, a perennial grass being developed as a bioenergy crop, under Dr. Erik Sacks at the University of Illinois, Urbana-Champaign.

I recently finished my Ph.D. (September 2011) in the Genetics Graduate Group at UC Davis as a member of the Jasieniuk lab in the Department of Plant Sciences. My dissertation research was on the evolution of invasiveness in blackberry (Rubus), particularly relating to hybridization and asexual reproduction. I have also written software in R for the analysis of polyploid data.

I graduated from Dartmouth College in 2004, having majored in Genetics, Cell & Developmental Biology and minored in Chemistry. From June 2002 to June 2004 I did my undergraduate thesis research in Thomas Jack's lab, where I worked on developing knockout mutants for a gene family putatively involved in floral development in Arabidopsis.

From November 2004 - July 2006 I worked at the Grape Genetics Research Unit in Geneva, NY. Under the direction of Amanda Garris, I worked on gene cloning and QTL mapping towards an understanding of light detection and winter dormancy in grapevine.
