• M. Pilar Fernandez – Assistant Professor – Allen School for Global Animal Health, Washington State University

Dr. Fernandez is an assistant professor at the Allen School for Global Animal Health at Washington State University. As a disease ecologist her research focuses on the eco-epidemiology of zoonotic diseases, and in particular, vector-borne diseases. She graduated from the University of Buenos Aires and has worked primarily on Chagas disease in Argentina, and tick-borne diseases in the Northeast USA during her time as a postdoc at Columbia University. Her main research interests lay in understanding the transmission of zoonotic diseases as complex socio-ecological systems, combining methods from epidemiology and ecology. The ultimate goal of her research is to identify critical factors affecting disease transmission, which will aid in the design of improved intervention strategies to alleviate the biological and socio-economic burden of these diseases in affected communities.

  • Danielle Tufts – Assistant Professor – Infectious Diseases and Microbiology Department, University of Pittsburgh

Dr. Tufts is a vector-borne disease ecologist interested in evolutionary genetics, pathogen transmission pathways, ecological drivers of pathogen emergence, and host-vector-parasite interactions and co-infections. Her goal is to enhance our understanding of these complex interactions by combining theory from disease ecology and genetics research with empirical approaches. She utilizes field collected and laboratory derived samples, mathematical models to connect these findings to patterns found in nature, and analyzes these samples using the molecular tools. Her previous projects have focused on understanding how tick-borne pathogens (Borrelia burgdorferi and Babesia microti) may facilitate and enhance infection in their natural reservoir host (Peromyscus leucopus) using field-derived data from a multi-year, longitudinal, mark-recapture study and a multi-state Markov model to assess transition likelihoods between different infection states. Dr. Tufts was the first investigator in the US to discover that vertical transmission (a non-vector mediated pathogen pathway) may be contributing to the high prevalence and emergence of B. microti in natural rodent populations. Currently, she is investigating host specialization of different B. burgdorferi strains, immunological maternal-mediated protection against B. microti infection, macro-micro parasite interactions, and behavioral and genetic analyses of invasive tick species: the Asian longhorned tick (Haemaphysalis longicornis) and the red sheep tick (Haemaphysalis punctata).

Avriel is a second year Masters student with a B.S. in Aquatic and Marine Science from SUNY College of Environmental Science and Forestry. Her experience with infectious diseases in aquatic ecosystems during her research work with United States Geological Survey led her to move to Ecuador in July of 2016. There she helped to provide relief from the 2016 7.8 magnitude earthquake and then co-founded an NGO, Walking Palms Global Health Initiative. The NGO focuses on disaster relief, holistic recovery, and research. Her current investigations look at Zika, Dengue and Chikungunya Viruses, disease ecology, psychology, integrating ecosystem- community health, and sustainable community development.

  • Evelyn Rynkiewicz – Postdoctoral Associate

Evie has a background in the ecology of parasites in wild mice in the US and the UK. She applies classic ecology tools and theories to parasite-host and parasite-parasite interactions to better understand how parasite communities assemble within hosts and how this influences individual hosts and the patterns of parasite co-infection we observe at the population and community scale. Evie worked on using controlled infections of white-footed mice with Borrelia burgdorferi and Babesia microti in the lab and transcriptomics to quantify variation in the host immune profile in relation to single and simultaneous and lagged co-infections.
