The work that I've been doing the past 10 years involves the use of clinical data to perform various sorts of clinical quality and utilization measures that monitor the quality care of patients, uncover inefficiencies in healthcare, and highlight areas that need attention to improve patient care.  Through these efforts, patient care is improved and life-saving solutions are identified.  I get to work with large volumes of data, innovate some pretty cool set-based procedures and perform all sorts of analytics,   This is how data geeks get to save lives!
