Brief Biography

Rebecca is an Upstate NY native from Skaneateles. She was introduced to veterinary medicine working with sheep and dairy cattle while growing up. She studied biomechanics of growing animals for her undergraduate thesis research.

Prior to her postion at the CDC, Rebeeca was a post-doctoral researcher at the Department of Population Medicine and Diagnostic Sciences, Cornell University.

Education

DVM/Ph.D., College of Veterinary Medicine, Cornell University, 2011

AB, Honors Biology, Harvard University 2003

Research Interests

Rebecca is interested in understanding pathogen transmission dynamics. She is studying Mycobacterium avium subspecies paratuberculosis (MAP) transmission on commercial US dairy farms. Her projects involve in vitro assessment of host and pathogen heterogeneity, fieldwork and mathematical model development.
