Biography and Research Information
OverviewAI-generated summary
Dr. Jonathan Laryea's research focuses on understanding and addressing disparities in colorectal cancer risk, incidence, and survival. His work investigates the impact of environmental factors, such as pesticide exposure, and dietary components, including choline and B vitamins, on colorectal cancer development. He also examines the influence of socioeconomic factors, specifically persistent poverty, on cancer survival rates.
Dr. Laryea's clinical research extends to the management of malignant bowel obstruction, comparing surgical and non-surgical approaches. He is also dedicated to global health needs in surgery, with a particular focus on enhancing colorectal surgery services in Ghana to meet growing demands. His work in this area includes assessing referral indications and endoscopic findings in tertiary care hospitals and creating fellowship programs to train more colorectal surgeons in West Africa.
His academic contributions include publications on colorectal cancer, surgical management strategies, and global health needs in surgery. Dr. Laryea holds an h-index of 12, with 54 publications and 463 citations. He leads a research group and collaborates with researchers at the University of Arkansas for Medical Sciences, including Mario Schootman, Chenghui Li, Ping-Ching Hsu, and Eryn K. Matich.
