WILLIAMS LAB - Key Persons


Hongsheng Gui

Job Titles:
  • Investigator
Hongsheng obtained his PhD in Statistical Genetics from the University of Hong Kong, and spent seven years in Hong Kong before moving to the USA. He is inspired by the phenomenon of missing heritability for genetic analyses of complex phenotypes. Most of his work and research are aiming to explore and prioritize genetic susceptibility variants, genes, and pathways for complex diseases using post-GWAS data mining technique and next generation sequencing. His current work is to use systems genetics approaches to investigate asthma diseases in African American population. He likes to play with his two lovely daughters in his free time.

Kyle Whitehouse

Job Titles:
  • Project Coordinator
Kyle graduated from Calvin College with a Bachelor's Degree in Sociology and Chinese Language. After conducting research in sociology and working abroad as a college English teacher, he is excited to contribute to the DIAMOND study as a project coordinator.

L. Keoki Williams

Job Titles:
  • Principal Investigator
  • Professor of Medicine at Wayne State University School of Medicine
Dr. Keoki Williams is a Professor of Medicine at Wayne State University School of Medicine and a Senior Scientist and co-director in the Center for Individualized and Genomic Medicine Research (CIGMa) at Henry Ford Health System. He graduated cum laude in both research and academics from the University of Michigan Medical School, and afterward he completed a medical residency in Internal Medicine at the Brigham and Women's Hospital, Harvard Medical School. Following residency, he worked for the U.S. Centers for Disease Control and Prevention (CDC) as an Epidemic Intelligence Service officer. During his research career, he has been a Howard Hugh Medical Institute-National Institutes of Health (HHMI-NIH) Research Scholar, a National Research Service Award recipient, and an Early Excellence Awardee from the American Asthma Foundation. He has been a senior staff physician and research scientist at Henry Ford Health System since 2001, and has received seven separate independent investigator (R01) awards from the National Institutes of Health during this time period. The scope of his research includes the fields of genetics, genomics, pharmacoepidemiology, pharmacogenomics, and epidemiology. His particular interests include assessing medication use and its effects in large patient populations and identifying the genetic predictors of medication response. He and his lab are actively involved in large-scale projects to identify the genetic causes of asthma, diabetes, cardiovascular disease (and fitness) and other common, but genetically complex, conditions.
