Congratulations to Megan McCain September 4th, 2014
Megan McCain has been named as a Technology Review TR35, the “35 innovators under 35″ who are changing the world. Megan’s received this distinguished honor for her current work at USC and at the DBG in developing a “heart-on-a-chip”. To read more about the TR35, click here.
Summer Researchers – Many thanks for all your efforts!! August 26th, 2014
The DBG would like to thank all of our Summer Researchers who contributed to our research this summer and when disaster struck during torrential rains and the lab flooded, they came to help rescue our equipment and supplies. We had several REU students, cadets from West Point, HU undergraduates and in coming undergraduates, plus a couple of high school students. Thanks for all your efforts.
Welcome to Lisa Scudder to the DBG! August 26th, 2014
The DBG would like to welcome our new Post-Doctoral Fellow, Lisa Scudder. Lisa joins us from laboratories of Professor Alfred L. George at Vanderbilt University, where she completed her Ph.D. in Pharmacology. We are excited about Lisa joining the team.
Congratulations for our new Ph.D.’s June 5th, 2014
