After completing a residency in emergency medicine, I joined the University of Maryland in 1993. Since arriving here, I have been actively involved with the University of Maryland Emergency Medicine Residency Program, serving as Site Director at Mercy Medical Center from 1996 to 2000, and as Director of Research Education from 2000 to the present. I was awarded an ACEP National Faculty Teaching Award in 2006.

From my days as a resident, I have been interested in research. After a few years of clinical practice, I pursued additional training at the University of Maryland, earning a Masters in Clinical Research. With an interest in the practice of emergency medicine, particularly bedside diagnosis, I have published on a variety of emergency medicine topics. My research has improved the use of orthostatic vital signs, point-of-care ultrasound, pulse oximetry, and helped better select patients for nasogastric aspiration, a painful procedure. In addition to helping residents with their research projects, I plan to continue my current line of investigation, solutions to difficult intravenous access.

I love the specialty of emergency medicine, and I devote a large proportion of my efforts to nationally promoting it. I have been a peer reviewer for 3 major emergency medicine journals, and was named Top Reviewer 2 years in a row for Annals of Emergency Medicine. Since 2006, I have been an Associate Editor for The Journal of Emergency Medicine and was named Senior Associate Editor in 2015. I am proud to serve as an oral board examiner for the American Board of Emergency Medicine.
