Professional Experience

Clinical informatician at the VA Center for Innovations in Quality, Effectiveness and Safety (IQuESt), and at the Baylor Institute for Clinical and Translational Research, 11/12/2018-present. Assistant professor, Baylor College of Medicine. I am a practicing physician with with significant personal experience writing reusable database, statistical, and machine learning computer code for research. I unify large collections of fragmented data elements to into clinically meaningful concepts, thus making diverse clinical research studies possible. This work is known by several names: secondary use of electronic health record data, clinical research informatics, or phenotyping. I interpret clinical language and systems for data pull engineers/analysts, or vice versa (interpreting technical language for clinical investigators). I access a data warehouse covering $> 20$ million unique individuals, and billions of observations, from 1999 to the present, aggregated from 130 VA sites (but incompletely standardized/harmonized). Major projects include disseminating algorithms to detect missed laboratory test follow-ups, and clinical trials matching. I also work as a teaching attending on the VA hospitalist service, supervising house staff and students. Supervisors: Hardeep Singh, Chris Amos, Andrew Caruso, Lindsey Gay.

Clinical informatician, Massachusetts Veterans Epidemiology Research and Information Center (MAVERIC), 10/20/2014-11/9/2018. Assistant professor, Boston University School of Medicine, 8/2016-11/2018, and reciprocal appointment as Lecturer, Harvard Medical School. My work enabled a genomic precision medicine platform and learning health system for cancer, as well as a 13,000-subject point of care, randomized comparative effectiveness trial of two antihypertensives. Developed (2016) a system to ensure reusable phenotyping algorithms for genomic association and other studies, still in use as of 2024. Personally exported and encrypted data from this system to the mirror system at Oak Ridge National Laboratory (2018). Served as co-program-director of the Big Data-Scientist Training Enhancement Program (BD-STEP) site in Boston, and as principal investigator on a study of genomic predictors of stage of lung cancer at presentation. Mentored an internal medicine resident, who helped me make a highly accurate natural language processing classifier of serum protein electrophoresis reports. Inpatient medicine teaching attending at the VA hospital. Supervisors (research): Nhan Do, Valmeek Kudesia, Mary Brophy, Louis Fiore. Clinical: Steven Simon, Jay Orlander, Anthony Breu.

Research collaborator, Massachusetts Institute of Technology, Laboratory for Computational Physiology, 12/6/2013-9/2016.

Pilot projects using multivariable adaptive regression splines, and Fourier spectral analysis. Coursework in epidemiology, biostatistics, data mining, machine learning, and grant writing, partially through Harvard School of Public Health Program in Clinical Effectiveness. Professor: Kenneth Mandl. Program director: Alexa McCray.

Urgent care physician, Harvard Vanguard Medical Associates, 10/15/2011-6/30/2018. Diagnose and treat outpatients with acute medical problems, e.g. infections, dehydration, sprains, abscesses, lacerations, pelvic conditions, initial management of fractures. Supervise nurse practitioners and physician assistants. Supervisor: David Meenan.

Internal medicine chief resident, Saint Louis University Hospital, 7/1/2010-6/30/2011. Managed and scheduled 130 residents. Academic appointment as instructor in internal medicine. Attended on inpatient & outpatient general medicine in university and VA hospitals. Accepted transfers, supervised and improved patient handoffs. Precepted medical students, ran morbidity/mortality and clinicopathologic conferences, and $\sim 100$ resident report conferences. Interviewed and helped select residency program applicants. Program director: Miguel Paniagua.

Research elective, 2/2007-4/2007. Association rule mining on a database of 12,000 outpatients and 40,000 diagnoses. Wrote Perl code to find associations between any given pair of diseases in a patient, and to output the strongest associations in an easily visualized format. Professor: Walton Sumner, Washington University in St. Louis.
