Just learned that the guitarist for Queen, Dr. Brian May, is a PhD astrophysicist who collaborated on a mission to sample an asteroid that will give insight into what the solar system was like 4.5 billion years ago. 🧪

I recently moved my lab to Purdue University and am looking for graduate students. We are working at the interface of population genomics, quantitative genetics and functional genomics to understand how plants adapt to extreme environments. Reach out if you would like to discuss potential projects.
