Dr. Caracappa has been a practicing health physicist for nearly 20 years, with more than a dozen of those as the radiation safety officer for increasingly broad and diverse programs.  As the Chief Radiation Safety Officer for Columbia University, he has responsibility for broad-scope clinical and research licenses for radioactive material and radiation producing equipment, a large cyclotron facility, and permits for use over several locations.  The radiation safety program he leads encompasses the activities at Columbia University, Columbia University Medical Center, New York-Presbyterian Hospital, Barnard College, the New York State Psychiatric Institute, and affiliated medical practices, with licensing from City, State, and Federal authorities.  He has previously served as Radiation Safety Officer for a number of academic and research programs, including a 100 MeV electron accelerator facility and a low-power research reactor. Dr. Caracappa is certified by the American Board of Health Physics in the comprehensive practice of health physics.

Dr. Caracappa has served both full- and part-time on the faculty at Rensselaer Polytechnic Institute, and has over 15 years of experience as the primary instructor for courses in Nuclear Engineering and Health Physics, including subjects such as radiation detection and instrumentation, health physics, nuclear physics, and laboratory experimentation.  He also led the RPI Reactor Critical Facility, a 100-watt research reactor, as Director and maintained an active research program in reactor physics and medical health physics, authoring or co-authoring over 25 peer-reviewed papers or proceedings and 100 conference presentation abstracts.
