Estimating the Size of Key Populations for HIV Surveillance: Existing Challenges and Opportunities to Improve Scientific Rigor 

Population size estimation is fundamental to public health research and surveillance. This quantity serves as the denominator in epidemiologic studies - calculating the burden of disease in the population of interest - while also providing targets to evaluate the reach and coverage of existing public health services. For marginalized communities, particularly those at higher HIV risk, reliable estimates for the population size present a challenge. In this talk, Dr. Paul Wesson will discuss the reliability of population size estimation methods, and recent developments he has made with colleagues to improve the rigor of these methods. 

Paul Wesson, PhD 

Dr. Wesson is a postdoctoral fellow in the Center for AIDS Prevention Studies (CAPS) at UCSF. He received his PhD in Epidemiology from UC Berkeley, where his dissertation research focused on methods to sample and estimate the size of hard-to-reach populations. While a fellow, he developed two novel approaches to estimating the sizes of key populations at risk for HIV infection; he also works with Dr. Sheri Lippman to apply rigorous statistical methods to investigate and quantify the social determinants of HIV infection among adolescent girls and young women in South Africa.
