Dr. Jonathan Sexton, Ph.D.

Assistant Professor, Internal Medicine, Division of Gastroenterology and Hepatology

Assistant Professor, College of Pharmacy, Medicinal Chemistry

Faculty Lead, Michigan Institute for Clinical & Health Research, MICHR, Drug Repurposing


Jonny Sexton has expertise in translational medicine, drug discovery and development with a specific focus on chronic liver diseases including non-alcoholic steatohepatitis (NASH) and non-alcoholic fatty liver disease (NAFLD). He is also trained in quantitative biology, high-throughput screening, medicinal chemistry, big data mining and multivariate statistical analysis and animal models of diseases relating to diabetes and obesity. Jonny also engages in entrepreneurial activities and is the founder of Curl Bio LLC , a startup designed to perform drug development for NAFLD and NASH.

Jonny is the faculty lead of the center for drug repurposing at Michigan Institute for Clinical & Health Research (MICHR) and possesses a bioactive drug library of approximately 6,000 compounds. This center takes on a collaborative approach in drug repurposing and the service is available to all labs in the University of Michigan.

The Sexton lab has strong extramural funding in the form of continuous NIH funding in the areas of human metabolism, diabetes, metabolic syndrome & animal models of human diseases including an active R01 and a previous R01 from NIDDK.


Laboratory Staff:

Tracey Schultz

Laboratory Manager


Mother Tracey is a loving, funny and wise woman that splits her life between Ann Arbor (as a Research Assistant Tech Lead) and Detroit (as a new millenium hippie). Tracey refused to accept the term “Grandma” when her grown daughters began their families and so, the name Mother Tracey was born. Tracey has become an integral component of Michigan Medicine with 15 years of employment in the department and over 20 years of experience working with viruses, bacteria, parasites, and now drug repurposing in mouse models. Tracey holds a Bachelors of Science in Cytogenetics from Eastern Michigan University and a Bachelors of Science in Forensic Investigation from Wayne State University.


Samuel K Handelman, PhD

Assistant Research Professor, Internal Medicine, Division of Gastroenterology and Hepatology

Director – Clinical Informatics, Michigan Institute for Clinical & Health Research, MICHR, Drug



Samuel Handelman is an interdisciplinary biologist and data scientist who applies multi-omics approaches and biochemical models to drive precision/personalized-therapy and to discover novel drug targets and indications. Dr. Handelman directly translates these molecular, mechanistic and population-genetic models into testable hypotheses in the Michigan Electronic Health Record. Real understanding of the molecular basis of human pathophysiology goes all the way to the clinic. Therefore, anything less than clinical translation indicates a failure of biological understanding.


Reid Fursmidt

Laboratory Technician


Reid Fursmidt is from West Bloomfield, MI and is the resident lab technician here in the Sexton Lab. He graduated from Michigan State University in 2017 with a degree in Cellular and Developmental Neuroscience. He then went on to receive his masters here at the University of Michigan studying Molecular and Integrative Physiology. Reid’s primarily role within the lab focuses on machine learning and the use of artificial intelligence in high-content screening. His current research interest includes NAFLD, diverticulitis, and IBD.



Graduate Students:

Sean McCarty

PhD Pre-Candidate, Medicinal Chemistry


Sean McCarty grew up in Columbia, IL, a small suburb of St. Louis. He graduated from the University of Illinois at Urbana-Champaign in 2018 with a Bachelor of Science in Chemistry and a Bachelor of Science in Molecular and Cellular Biology. During his time at UIUC, Sean studied under Prof. Scott E. Denmark and focused on generating new chemical techniques for synthesizing silicon heterocycles. His current research includes performing medicinal chemistry on drug-like molecules that target diabetes and developing methods for applying AI in pathology.


Jesse Wotring

PhD Pre-Candidate, Medicinal Chemistry


Jesse Wotring grew up in Clinton, Michigan and graduated from Eastern Michigan University in 2017 with a degree in Professional Biochemistry. At Eastern, Jesse trained under Dr. Ingo Janser where he studied chalcones and their potential as antitumor agents. Jesse also worked at Cayman Chemical Company in the forensic chemistry department doing a wide spectrum of organic synthesis. In the Sexton lab, Jesse focuses on non-alcoholic fatty liver disease, diverticulitis and type II diabetes. Outside of the lab, Jesse enjoys the Detroit Pistons and eating food.


Charles Jian Zhang

PhD Pre-Candidate, Medicinal Chemistry


Charles Zhang is the lab’s sneaker connoisseur from Los Angeles, California and received his Bachelor of Science in Biotechnology with a minor in Chemistry from California State Polytechnic University, Pomona. During this time, he trained under Dr. Andrew Steele where they studied the expression of circadian rhythm gene expression. Charles then went on to receive a Master of Science in Pharmaceutical Sciences from Western University of Health Sciences where he trained under Dr. Peter Oelschlaeger and studied mutations in metallo-β-lactamases. In the Sexton lab, Charles now studies liver inflammation, esophageal adenocarcinoma, and designs novel imaging techniques.


Undergraduate Students:
