Integrating traditional epidemiological methods with cutting-edge molecular techniques, Lifang Hou’s research aims to identify key molecular markers and understand their role in diseases at the population level. Hou is focused on pinpointing risk factors that may cause chronic diseases, as well as biomarkers that reflect past exposures to disease risk factors and those that may predict disease risk or prognosis. She has studied various biomarkers, including genetic factors that determine an individual’s susceptibility to disease, and biomarkers that can be altered by the environment, such as telomere length and epigenetic factors. Hou seeks to understand the biological mechanisms linking environmental risk factors with the development of disease, ultimately leading to the development of effective tools for precision prevention. Hou is a professor of preventive medicine and chief of cancer epidemiology and prevention at the Feinberg School of Medicine. She is also the director of the Global Health Initiative at the Robert H. Lurie Comprehensive Cancer Center. Hou is a member of the Blue Ribbon Panel of experts and advocates who inform the direction and goals of former Vice President Joe Biden’s National Cancer Moonshot Initiative.
