Epidemiology Research

The Epidemiology Department has a strong track record of research. The department conducts a wide range of investigations from molecular and genetic markers, plasma biomarkers, lifestyle factors to health informatics. In addition to the investigator-initiated research projects below, we are committed to multidisciplinary collaborative research toward assessing the distribution and determinants of human illness with the aim of establishing reasoned preventive and control measures.

Jiali Han, PhD

Professor, Epidemiology Department Chair

Dr. Han is interested in understanding the influence of genetic and environmental factors on the etiology and prevention of skin lesions. His genetic epidemiological research started with the etiology of skin cancers and expanded to other skin lesions such as psoriasis, moles, and acne. Besides a series of genetic susceptibility investigation, he has also conducted a great deal of epidemiological research to identify lifestyle and environmental risk factors and comorbidities for skin cancers, psoriasis, and acne. He has played a leading role in large national and international collaborative consortia on melanoma, non-melanoma skin cancer, and human pigmentation. Currently he leads post-GWAS collaborative projects examining the biological function of genetic variants using bioinformatics and molecular biology tools. In addition, he recently has conducted cancer network research and pharmacoepidemiology research.
