Currently, I am a Ph.D student in Ecology and Evolution at the University of Chicago. I am advised by Dr. Cara Brook and currently exploring longitudinal viral shedding dynamics in Madagascar’s three endemic fruit bats: Pteropus rufus, Rousettus madagascariensis, and Eidolon dupreanum. I am particularly interested in doing surveillance for RNA viruses, chiefly filoviruses, coronaviruses, lyssaviruses, and henipaviruses. I have also been working on describing novel coronaviruses and picornaviruses from fecal and urine samples collected from these fruit bats, in collaboration with the Chan Zuckerberg Biohub. I am especially interested in developing my career in disease ecology with teaching in mind. Part of the initiative of developing PCR assays for viral surveillance is to expand in-country surveillance to be utilized by Malagasy scientists. The Brook lab Malagasy team members are concurrently developing seroprevalence assays for these same viruses. Additionally, I am involved in organizing the instructing part of the yearly workshop: Ecological & Epidemiological Modeling in Madagascar (E2M2).
I had always been interested in viruses and ecology, and my research interests span all aspects of disease ecology and evolution, with a particular interest in holding a One Health view on these topics. In my undergraduate at Keystone College in rural Pennsylvania, I was exposed to field and molecular research through surveillance studies in deer ticks (Ioxdes scapularis) for Borrelia with Dr. Vicki Stanavitch and Dr. Darryl Horn. Subsequently, I did a REU in the summer between my undergraduate and master’s with Dr. Brian Leydet at SUNY-ESF, which helped expand my molecular toolbox while continuing to work on tick pathogens. My master’s on the pathogenesis of H5N1 influenza in human precision cut lung slices was completed at the University of Pittsburgh advised by Dr. Simon Barratt-Boyes. After graduating, I stayed as a research technician and worked in a couple of projects in assessing universal flu vaccine success in NHP’s exposed to aerosolized H5N1 influenza. This allowed me to get extensive experience in rigorous lab safety in a BSL3+ lab working with zoonotic pathogens. Once the COVID-19 pandemic began, our unique ability to work with high biosafety level pathogens allowed me to work on projects on SARS-CoV-2 infectivity of asthmatic lung epithelial cells, with the interest of testing treatments.
As one of the student representative for GBatNet, I am pleased to co-lead two GBatNet working groups which are; “How has the bat immune system evolved and influenced bat diversity” and “How old is this bat”.
