Till Hoffmann
I develop affordable, equitable public health monitoring solutions that impose a minimal burden on the population. My research connects models with complex, often messy real-world datasets, such as data not originally intended for research purposes. I am particularly interested in open and reproducible science based on data that adheres to the principle of privacy by design—without compromising the insights we can glean.
Previously, I was a Postdoctoral Research Associate at Imperial College London, Staff Research Scientist at Spotify, and Principal Research Scientist at Sonalytic. I received my PhD from Imperial College London under the supervision of Nick S. Jones and Master of Physics from the University of Oxford.
Yuke (Andrew) Wang
My research interests span the areas of exposure assessment, wastewater surveillance, and infectious disease transmission. A common thread in his research is in understanding the human-environment interface with respect to infectious diseases. I design, develop, and evaluate statistical and mathematical models to support evidence-informed public health decision-making in low- and middle-income countries (LMICs) and in the United States.
I am an Investigator of the Emory Center for Infectious Disease Modeling & Analytics and Training Hub (CIDMATH) and a Core Investigator at the Center for Global Safe Water, Sanitation, and Hygiene (CGSW).
