Director, Proteomics and Metabolomics Core Facility

Dr. Thompson's research focuses on the development and deployment of proteomics and metabolomics mass spectrometry techniques for the analysis of biological systems. He served as the Assistant Director of the Proteomics and Metabolomics Shared Resource in the Duke School of Medicine from 2007-2021. He currently maintains collaborations in metabolomics and proteomics research at Duke, and develops new tools for chemical analysis as a Principal Scientist at 908 Devices in Carrboro, NC.

My research interests focus on the study of chronic liver disease and primary liver cancer, particularly from metabolic dysfunction associated steatotic liver disease (MASLD), formerly called nonalcoholic fatty liver disease (NAFLD).  As part of the MASLD Research Team at Duke, we are investigating the role of environmental contaminants, epigenetics, and genetics on the development of advanced fibrosis and liver cancer from MASLD and other chronic liver diseases.  We are also interested in understanding risks for progressive liver disease including developmental programming and in utero exposures and have been investigating these risks through studies of the Newborn Epigenetics Study (NEST).  The long term goal of our research is to develop non-invasive biomarkers to identify those patients at increased risk for cirrhosis and end stage liver disease in order to risk stratify patients as well as to develop better preventative and therapeutic strategies.

My research interests include:
Fine Needle Aspiration of Liver, Gastrointestinal Tract, and Pancreatic Lesions
Biliary Duct Brushings
Nonalcoholic Fatty Liver Disease/NASH
Liver Fibrogenesis

Our lab has a long standing interest in liver injury and repair. To learn more about the mechanisms that regulate this process, we study cultured cells, animal models of acute and chronic liver damage and samples from patients with various types of liver disease. Our group also conducts clinical trials in patients with chronic liver disease. We are particularly interested in fatty liver diseases, such as alcoholic fatty liver disease and nonalcoholic fatty liver disease (NAFLD).

Research by our group has advanced understanding in two main areas: 1) immune system regulation of liver injury and regeneration and 2)the role of fetal morphogens, such as the hedgehog pathway, in regulating fibrotic responses to liver damage. Our basic research programs have been enjoyed continuous NIH support since 1989. We welcome students, post-doctoral fellows and visiting scientists who have interests in this research area to contact us about training opportunities and potential collaborations.

Since 2001 we have also been an active participant in the NIDDK-funded Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN), a national consortium comprised of 8 university medical centers selected to generate a national registry for patients with NAFLD and to conduct multicenter treatment trials for this disorder. We are actively recruiting patients for this program, as well as a number of other industry-supported NAFLD studies.
