Bio

I am an infectious disease epidemiologist who has extensively used mathematical modeling in my work. I have been especially active in the COVID-19 pandemic response and have used transmission models to help inform the public health response. Some recent outcomes of my work included help to inform CDC's guidance on social distancing for vaccinated individuals, shaping CDC guidance for surface decontamination and the role of fomite transmission during the pandemic, and informing WHO COVID vaccine allocation through the COVAX program. I was PI of a small grant from WHO that allowed us to work extensively with WHO to shape their vaccine program. I am currently working with SHIELD Illinois to estimate the impact of their PCR testing program on COVID 19 and using a transmission model to predict optimal allocation of testing resources during future resurgences of COVID-19, with potential application to other pathogens. I also work on enteric pathogen transmission, with a focus on norovirus and rotavirus. I previously worked with two MIDAS-affiliated faculty as a postdoctoral fellow (Dr. Benjamin Lopman and Dr. Joseph Eisenberg) and am looking to become affiliated myself as I start my own research group as a new assistant professor at UIUC.
