Layne Dylla, MD, PhD

Assistant Professor

University of Colorado School of Medicine

Dr. Dylla has a passion for medicine and using research to advance her treatment of many patients. She pursued this passion for medicine and research as dual MD/PhD student at the University of Colorado in the Medical Scientist Training program where she studied the oncogenic role of microRNAs in Ewing Sarcoma.

David H. Adler, MD, MPH

Professor, Department of Emergency Medicine

University of Rochester

Dr. Adler, MD, MPH, is an emergency physician, educator and researcher. He received his medical training at the University of California at San Francisco and his residency training in emergency medicine at Highland General Hospital in Oakland, California. Dr. Adler has been core faculty in the University of Rochester’s emergency medicine residency program since 2006. He is the Vice Chair of Emergency Medicine, Research, and also directs the SAEM-approved Emergency Medicine Research Fellowship.

Dr. Adler is the site principal investigator for URMC’s participation in the SIREN network and has served as site-PI for a number of multi-center federal and industry sponsored trials.

Dr. Adler’s research background focused on Human papillomavirus and cervical cancer risk among South African women with HIV. This work generated a specimen repository housed at URMC that is now being used, in collaboration with colleagues from Infectious Diseases, to investigate the reproductive tract microbiome in HIV-infected women.

Dr. Adler is currently the principal investigator in a line of research evaluating interventions to increase cancer screening uptake among emergency department (ED) patients. Disparities in healthcare access are often magnified among ED patients who are disproportionately likely to be non-adherent with cancer screening recommendations – making the ED a target-rich environment for interventions that increase screening uptake.

Dr. Adler is Co-Chair of the NCI-supported Comprehensive Oncologic Emergencies Research Network (CONCERN).

The results of this work will help to inform selection and development of learning materials for future emergency medicine education.

Rebecca E. Cash, PhD

Massachusetts General Hospital

"An Evaluation of the Current State of Prehospital Routing Decisions for Stroke"

I am an assistant professor of emergency medicine at Harvard Medical School, research staff at Massachusetts General Hospital, and a biostatistician/epidemiologist at the Emergency Medicine Network (EMNet). I provide statistical support and expertise for all EMNet projects. I am also a paramedic with expertise in emergency medical services (EMS) research.
