CREST​ NETWORK

We in the CREST Network enjoy including residents in our studies. We have worked with residents from several emergency medicine, internal medicine, pediatric and OB programs in California. Below we list resident projects that have been published or are in press, either in full or abstract form. Resident co-investigators and their respective programs are highlighted in bold font. Residents (or medical students) often present their studies at national meetings.
