Physician Bio

Dr. Jamal is a general gastroenterologist with additional training and expertise in liver diseases (hepatology). With the assistance of a nurse practitioner and dietician, Dr. Jamal leads the Liver Clinic which focuses on patients with complicated liver diseases that require more intensive management. This clinic has access to state of the art imaging, interventional radiologists, oncologists, and Hepatobiliary surgeons in order to provide truly comprehensive attention to our patients. A newly available technology called the Fibroscan will enhance our accuracy for assessing damage to the liver without having to do a liver biopsy.

Another passion of Dr. Jamal’s is the development of clinical research trials. This will open up new opportunities for our patients with specific GI diseases. Our most recent trials have been for the treatment of eosinophilic esophagitis, constipation and patients with low platelets from cirrhosis of the liver.

Dr. Jamal is also our center’s expert for the treatment of Barrett’s Esophagus, a pre-cancerous condition which can lead to esophageal cancer. He utilizes a technology called radiofrequency ablation and/or cryotherapy in order to eliminate the Barrett’s esophagus all through noninvasive means.

Dr. Jamal has a passion for teaching students, nurses and physicians. He is focused on providing compassionate care as part of a team of excellent physicians which is what keeps him glued to the St. Jude Heritage family.
