Biographical Narrative

Dr. Jordan Karlitz graduated from the University of California at Berkeley with a degree in molecular biology and genetics. At Berkeley, he spent several years working in a molecular biology lab where his research focused on the cloning of CDRK, a voltage gated potassium channel. This led to his graduation with university and departmental honors. He subsequently attended the McGill University Faculty of Medicine in Montreal where he received his medical degree in 2000. At McGill, Dr. Karlitz was vice president of the William Osler society, a organization dedicated to educating students and faculty on the history of medicine.

Dr. Karlitz received his internal medicine training at the Columbia University College of Physicians and Surgeons/New York Presbyterian Hospital. During his training at Columbia, he also completed a fellowship in medical ethics sponsored by the Arnold P. Gold foundation. Through this foundation, Dr. Karlitz conducted research concerning the ethics of stem cell research and delivered a series of university lectures on this topic. He subsequently completed his fellowship in Gastroenterology and Hepatology at the Albert Einstein College of Medicine/Montefiore Medical Center in 2006. At Einstein, his research focused on the treatment outcomes of urban minority patients with hepatitis C.

After finishing his fellowship training, Dr. Karlitz joined a private practice group in the Washington D.C. area. While in practice, Dr. Karlitz was a clinical assistant professor at the Georgetown University School of Medicine and spent a significant proportion of his time working with medical students and residents. Desiring a full time academic career, Dr. Karlitz joined the faculty at the Tulane University School of Medicine in the division of Gastroenterology in 2008 as assistant professor or medicine.

At Tulane, Dr. Karlitz's clinical and research focus centers on familial colon cancer syndromes and inflammatory bowel disease. He has started a familial GI cancer clinic at the Tulane Cancer center that is linked to the Hayward Genetics center and currently sees patients with familial colon, stomach and pancreatic cancer. He recently completed a preceptorship in inflammatory bowel disease sponsored by the Crohn's and Colitis Foundation of America at the Massachusetts General Hospital and sees underserved patients with Crohn's Disease and Ulcerative colitis, along with patients with familial cancer syndromes, at University Hospital (Charity Hospital system). He is currently the associate program director of the gastroenterology fellowship program at Tulane.
