Maria Georgieva

CCDD Postdoctoral Research Fellow, 2015-2018

Maria Georgieva, PhD, joined the Center for Communicable Disease Dynamics at the Harvard T.H. Chan School of Public Health in the fall of 2015 as a Research Fellow in the laboratory of Dr. Marc Lipsitch. She received her PhD from Emory University in 2015 where she studied modulation of host immune responses by Mycobacterium tuberculosis. In the Lipsitch Laboratory, Dr. Georgieva studied immune escape by antibody antigens of Streptococcus pneumoniae.…

Elsa Hansen

CCDD Postdoctoral Research Fellow, 2011-2014
Current Title: Research Associate, The Pennsylvania State University

I am a mathematical biologist, broadly interested in the evolution and ecology of infectious disease. My work focuses on re-formulating biological questions in to mathematical models that can then be analyzed. The ultimate aim of the analysis is to provide a stronger foundation for scientific study and experimentation. I am currently focused on questions about drug resistance.
