Qu Cheng is a postdoc working with Prof. Justin Remais on theoretical and applied analysis of infectious disease surveillance systems. Her research uses simulation methods to identify optimal surveillance system configurations for better estimating certain epidemiologic parameters. Qu is developing statistical models and mathematical models to understand the spatio-temporal environmental and socio-economic drivers of infectious diseases. Qu received her PhD in Ecology from Tsinghua University, and her Bachelor’s degree in GIS from Zhejiang University. Her prior research included global land cover mapping using satellite data; exploring rural-urban disparities in infectious disease reporting in China; and using both deterministic and stochastic mathematical models to understand the role of imported cases, climate, and interventions in contributing to an unprecedented dengue outbreak in the large subtropical city of Guangzhou.
