After completing a two-year ultrasound fellowship at Brigham in Boston, I moved down to Brown to join our ultrasound division. Ultrasound is a great platform for education, research and global health as well as an invaluable clinical resource. I am particularly interested in resident and fellow education, use of ultrasound in resource limited areas and ultrasound research. I have fallen completely in love with Rhode Island because there is nowhere else to be in the summer and the restaurants are amazing.

Academic Interests: Critical and procedural applications of point-of-care ultrasound.

I remain stoked about point-of-care ultrasound after teaching and scanning since 2002. It's like x-ray vision, how could that every be boring? Ultrasound guided analgesia and rapid diagnosis of critical illness are particularly satisfying. I've been at Brown since 2008 and love the program, the town and the state. On the non-medical side I run an Aikido Kokikai martial arts school, surf when conditions are good, and enjoy my family. 


Erika Constantine, MD
Director of Pediatric Emergency Ultrasound

Academic Interests: Pediatric emergency ultrasound, ultrasound education, pediatric appendicitis.

Point-of-care ultrasound sits at the intersection of everything I love about practicing medicine: Hands-on patient care, cutting-edge technology, amazing images of human anatomy and (an EM physician favorite), instant gratification through rapid diagnosis.

The best part of my job is finding new ways to teach ultrasound to medical students, residents, fellows and faculty - through interactive sessions, hands-on bedside teaching, and local, regional and national workshops. I also spend a lot of time expanding the reach of point-of-care ultrasound by collaborating with other pediatric sonogeeks around the globe to further education and research in this rapidly changing field.

I have been involved in teaching and administration of emergency ultrasound since 1998. I have had the opportunity to develop didactic programs, and lead integration of emergency ultrasound into emergency department clinical practice. My academic and research interests are in the implementation of emergency ultrasound into physician and nursing clinical practice.

I completed my ultrasound fellowship at UConn in 2013 and join Brown program in 2016. I joined the Division as the Director of Medical Student Emergency Ultrasound Education and I work with the medical school on their point-of-care ultrasound curriculum. I am also an expert scuba-diver, and I travel internationally to enjoy cave diving among other adventures!

I completed my emergency medicine training and point of care ultrasound fellowship in the second greatest city in the world at Maimonides Medical Center in Brooklyn. In 2016 my family and I made the plunge to move to the greatest city, Providence. I love teaching and mentoring and helping trainees across all the stages work on achieving their own goals for their education and careers.

I am originally from Southern New Hampshire and just moved up to Pawtucket, RI from Boston this past summer. I am Dominican- American and am fluent in both Spanish and English. I have been scanning for 5 years in the Boston and greater Boston area. I look forward to exploring beautiful Rhode Island and working with the ultrasound division at Brown emergency medicine.

I was lucky enough to match to Brown for my Emergency Medicine Residency. After graduation I moved to Chicago where I completed my Emergency Ultrasound Fellowship at the Cook County – Rush EUS Fellowship. I was then kept on as faculty at Cook County and enjoyed Chicago for 6 years until my family and I decided we needed a change of scenery to come home to New England to settle down closer to family. I am extremely excited to be back at Brown with an amazing group of residents and faculty. My passion is ultrasound education. It’s one of the very few true bedside teaching opportunities we have and I love it. My goal is to make sure every resident, attending, fellow and student receives the ultrasound education they need and desire for their careers to help them take the best care of patients they can.
