Congratulations to thesis student Ben Augenbraun ’15 who is the 2015 A.P.S. LeRoy Apker Award  WINNER !!! (the Apker Award is the nation’s top honor for undergraduate physics research).  We wish Ben the very best as he begins in the Ph.D. program at Harvard this fall.  

Former group member, and now Williams physics department colleague, Charlie Doret ’02 was the 2002 Apker Award winner.  All together FIVE Williams physics majors have won this award.

Here is a link to Ben’s undergraduate thesis:
Augenbraun thesis (6.2 MB)

June, 2015

We welcome Sauman Cheng ’16 and Allison Carter ’16 to the lab this summer , who will begin their thesis work, and will be joined by Nathanial Vilas ’17, Milinda, and Prof. Majumder.

Here is a picture of the summer 2015 research group:
