Additionally, he was Pathologist-in-Chief at Vanderbilt University Hospital and Director of Clinical Laboratories.

His basic research program has focused on fatty acids and their metabolites. Dr. Laposata's clinical expertise, for both patient care and clinical research, is in blood coagulation, with a special expertise in diagnostic errors. He has authored more than 170 peer-reviewed publications in basic and clinical research. His work on diagnostic errors earned him an appointment to the 21 member panel of the National Academy of Medicine which issued the 2015 report on Improving Diagnosis in Healthcare.

Dr. Laposata is the recipient of 14 major teaching prizes at Harvard, the Massachusetts General Hospital, and the University of Pennsylvania School of Medicine.

His textbook, in its third edition, Laposata’s Laboratory Medicine, has been translated into multiple languages. It is used globally by those learning laboratory medicine and those using the clinical laboratory. In a peer nominated survey performed by The Pathologist, a journal reporting on the practice of pathology, the November 2015 issue identified Dr. Laposata as the most influential pathologist in the United States, and the third most influential pathologist in the world.
