Lauren Childs

CCDD Postdoctoral Research Fellow, 2012-2015 and Research Scientist, 2015-2016
Current Title: Assistant Professor, Virginia Tech, Department of Mathematics

Dr. Childs develops mathematical models and computational tools to address fundamental biological questions. Her current research focuses on combining immunological within-host dynamics with epidemiological spread of disease to understand patterns of transmission. Her past research includes mathematical and computational models with applications to infectious diseases, immunology, CRISPR and coupled oscillators.

Virgie Fields

CCDD Student-MS, 2013-2015
Current Title: Healthcare-Associated Infections Epidemiologist, Virginia Department of Health

Virgie is currently a Healthcare-Associated Infections (HAI) Epidemiologist at the Virginia Department of Health. Before starting her current position, she completed the CDC/CSTE Applied Epidemiology Fellowship at the Arkansas Department of Health, where she focused on HAI and other infectious disease projects. She earned a Master of Science degree in Epidemiology at the Harvard T.H. Chan School of Public Health with a concentration in Infectious Disease Epidemiology, and a Bachelor of Science…

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: Assistant Research Professor, 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.

Matt Hitchings

PhD Student, 2013-2018
Current Title: Postdoctoral Associate, Department of Biology, University of Florida

Matt Hitchings earned his PhD in Epidemiology in September 2018, working with Dr. Marc Lipsitch. He is interested in using disease transmission models to aid in the design of vaccine studies, particularly in the context of emerging infections.

Kate Langwig

CCDD Postdoctoral Research Fellow, 2015-2017
Current Title: Assistant Professor, Virginia Tech

Kate Langwig earned a bachelors degree at Union College, Schenectady, NY in 2008, and a Ph.D. from the University of California Santa Cruz in 2015. Her work bridges ecology and epidemiology to address questions on the epidemiological consequences of host heterogeneity. Please click here for more information about Kate Langwig.

Jennifer Lai

Postdoctoral Research Fellow
Center for Communicable Disease Dynamics (CCDD)

Jenn is a bioengineer who trained at MIT and later at the Thayer School of Engineering at Dartmouth College for her PhD. There, as a protein engineer, she worked on developing vaccine immunogens to focus humoral immunity on epitopes associated with protective antibody responses for HIV-1 and Dengue virus. Such “rational vaccinology” approaches are informed by the structural characterization of monoclonal antibodies. As a Schmidt Science Fellow in the Mina…
