Bryan Grenfell, PhD

Bryan GrenfellBryan Grenfell, PhD, is a Professor of Ecology and Public Affairs, Department of Ecology and Evolutionary Biology, Woodrow Wilson School at Princeton University. He had been a faculty member at the Pennsylvania State University since 2004, previously spent 14years at the University of Cambridge and four years at the University of Sheffield. He holds a PhD from the University of York. Dr. Grenfell has over 25 years experience in disease dynamics research with a main focus on the spatio-temporal dynamics and control of acute infectious diseases, such as measles. He has advised the World Health Organization on the global burden of measles, rotavirus and pneumococcus and has authored around 200 scientific papers. He is a Member of the Editorial Board of the PLoS Biology, a Fellow of the Royal Society of London, and a Member of the American Academy of Arts and Sciences. He has been awarded the T.H. Huxley Medal from Imperial College, the Scientific Medal of the Zoological Society of London and the Order of the British Empire.

Nimalan Arinaminpathy, PhD

Nim ArinaminpathyNimalan (Nim) Arinaminpathy is a postdoctoral researcher in the Ecology and Evolutionary Biology Department at Princeton University. He uses mathematical modelling to explore the dynamics and control of infectious diseases, with particular interest in the 'phylodynamics' of pathogens such as influenza virus: that is, the interactions between pathogen evolution and epidemiology. Nim is also interested in novel and emerging vaccine technologies, and their potential population-level implications for the control of major infectious diseases, including influenza and pertussis. When not at Princeton, Nim is periodically on secondment to the US Centers for Disease Control and Prevention.

Nita Bharti, PhD

Nita BhartiNita Bharti, PhD, is a post-doctoral research associate in the Ecology and Evolutionary Biology department at Princeton University. Nita’s research focuses on using statistical models and satellite imagery to analyze the spatial spread of infectious diseases of humans in West Africa. She is interested in understanding how the movement of people affects the spread of these diseases, particularly movement across political boundaries. She works on measles in Niger and meningitis in Niger, Mali, and Burkina Faso. Her goal is to understand the role of human movements in the spread and spatial distribution of infectious diseases.

Petra Klepac, PhD

Petra KlepacPetra Klepac, PhD, is a postdoctoral researcher at Princeton University, Department of Ecology and Evolutionary Biology. After having studied biology and ecology from 1996 to 2001 at the University of Zagreb, Croatia, she completed her PhD as part of the joint program in biological oceanography at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution, USA. As a 2007 UNESCO-L'Oreal Postdoctoral Fellow at the Pennsylvania State University, she studied the optimal control of infectious human diseases, focusing on childhood measles. Her research interests fall in two main categories: optimal control of infectious diseases, and dynamics of predator-prey and host-pathogen population interactions.

Jessica Metcalf, PhD

Jessica MetcalfJessica Metcalf, PhD, has been awarded a Royal Society Fellowship held at Oxford University. Dr. Metcalf’s research employs mathematical and statistical tools to identify the determinants of infectious disease dynamics for a range of childhood infections, and test control strategies, particularly for rubella. As a part of the Vaccine Modeling Initiative (VMI), her efforts have focused on the development of strategic models to establish key variables such as the required minimum levels of coverage for introduction of vaccination against rubella, developed within her role as a Technical Advisor acting in support of the WHO working group on rubella. She is also currently involved in analysis of long-term spatio-temporal data on rubella  (e.g., from Mexico, Peru and South Africa), with particular focus on the likely impact of the introduction of rubella vaccination into South Africa (where it has yet to be introduced), in collaboration with the South African National Institute of Communicable Diseases.

Virginia Pitzer, ScD

Virginia PitzerVirginia Pitzer, ScD, is a Postdoctoral Research Fellow in the Department of Ecology and Evolutionary Biology at Princeton University. Her research focuses on using mathematical modeling and statistical methods to examine heterogeneities in the transmission and distribution of infectious diseases. Her current research focuses on developing transmission models that incorporate specific information on the dynamics of rotavirus infection, such as the incomplete nature of immunity and the interaction of different strains, to explain the spatiotemporal pattern of rotavirus epidemics in the United States. As part of the Vaccine Modeling Initiative (VMI), her efforts will focus on extending the models to the context of developing countries, where the combination of higher birth rates, higher transmission rates, and greater strain diversity could lead to perverse consequences for rotavirus vaccination.
