Dr. Brian Eisenback

Associate Professor of Biology
Co-Director, Bryan Center for Undergraduate Research


Dr. Brian Eisenback graduated with honors from Bryan College in 2002 and received his Ph.D. in Entomology from Virginia Tech in 2008.  His doctoral work investigated the prey-mediated effects of imidacloprid on two predators of the hemlock woolly adelgid. 
 
Dr. Eisenback is the co-director of the Bryan Center for Undergraduate Research, which hosts a research conference during the spring semester. See the BCUR website for more details.
 
Dr. Eisenback enjoys all things outdoors.  He regularly pokes around in the woods at Cumberland Trail State Park and enjoys taking photographs of anything and everything outdoors.  He enjoys playing soccer in his spare time as well as reading any book that has to do with science.  His wife Ashley is a local house-call veterinarian, and their daughter Madeline was born in February 2012.
