Beyond medical education, Dr. Geisler pursed training in research methods and public health.

He is a health services and outcomes researcher, a decision-analytic modeler and health economist; he served as a co-editor of a peer-reviewed journal in those fields, "Value in Health", for nine years and is currently on the editorial board of "Pharmacoeconomics". Dr. Geisler's research had applications across medical conditions although most were in cardiovascular disease. He enjoys teaching as well as running quality improvement/patient safety (QI/PS) projects. Recently, Dr. Geisler has become interested in "big data" and how to use routinely collected health information for research and QI/PS.

Dr. Geisler's ultimate career goal is to be an active citizen in the academic hospital medicine community.
