OverviewAI-generated summary
Dr. Jonathan A. Laryea's research focuses on colorectal cancer, including its screening, detection, and management. He has investigated the association between pesticide exposure and colorectal cancer risk and incidence through systematic reviews. His work also includes studies on racial disparities in colorectal cancer and the evaluation of abdominal approaches to rectal prolapse.
Dr. Laryea has also been involved in research concerning the surgical and non-surgical management of malignant bowel obstruction, as well as the use of ipilimumab-induced colonic perforation as a medical case study. His expertise extends to the radiological evaluation of rectal cancer and the prophylaxis of venous thromboembolism. He holds an endowed chair in surgery and serves as Vice Chair for Quality for the Department of Surgery at the University of Arkansas for Medical Sciences (UAMS).
His academic background includes a medical degree from the University of Ghana Medical School, research training at Johns Hopkins University, and surgical residency and fellowship training at Yale University Affiliate Waterbury Hospital and Georgia Colon and Rectal Surgery Clinic, respectively. He is board-certified in general surgery, colorectal surgery, and clinical informatics, and holds a Master’s degree in Biomedical Informatics. Dr. Laryea leads a research group and has published 56 papers, with an h-index of 12 and over 500 citations.
