Katia Koelle, PI

Katia is a theoretical ecologist interested in the population dynamics of infectious diseases and, more generally, in biological systems in which a population’s evolutionary dynamics occur on the same timescale as its ecological dynamics. Currently, her research focuses on understanding the epidemiological dynamics of infectious diseases in the context of extrinsic forcing (e.g., climate variability) and nonstationarities (e.g., climate change, long-term public health interventions, demographic changes), as well as in the context of rapid evolutionary changes. She is also interested in how phylogenetic comparative analyses can be extended to allow for more mechanistic representations of ecological interactions, thereby allowing the interaction between ecological and evolutionary dynamics to be considered more explicitly at longer timescales.

Ashley Sobel, MSTP (MD/PhD) student

Ashley’s main interests are in using ecological and evolutionary dynamics of infectious disease to understand and predict the emergence of zoonoses, and how recently emerged pathogens adapt to new host populations. Currently, she is focusing on using ‘phylodynamic’ models to better understand the development of feline infectious peritonitis in domestic cats. Her work in the coming years will focus on developing models for virulence evolution in seasonal and pandemic influenza viruses, as well as within-host models to better understand patterns of disease severity in flu.

 

Diana Vera Cruz, Computational Biology and Bioinformatics PhD student

Diana’s research focuses on sequence analysis of cytomegalovirus (CMV) from maternal and fetal samples to determine the effects of treatment on transmission. Her work has been in close collaboration with Sallie Permar and Cody Nelson in the Duke Medical School.

Olivia Yvellez, Associate in Research

Olivia’s research focuses on the effect of spatial expansions on rapidly evolving viruses, most notably rabies virus and influenza virus.
