Carla J. Berg, PhD, is an Associate Professor in BSHE at the RSPH. She received her Ph.D. in clinical health psychology from the University of Kansas, completed her residency training at Massachusetts General Hospital/Harvard Medical School in behavioral medicine, and then completed her postdoctoral training at the University of Minnesota in the Department of Medicine. Her research primarily focuses on tobacco control among special populations, specifically adolescents/young adults and cancer survivors. She has expertise in developing and testing interventions involving technology-based approaches, behavioral counseling, and pharmacotherapy. She also has a significant interest in cancer survivorship more broadly, addressing quality of life and improved health behaviors among this population. She has received funding from NIH, the CDC, and various other internal and external sources to support her research.

Natalie Crawford, PhD, MPH, is an Assistant Professor of Behavioral Sciences and Health Education at the Rollins School of Public Health, Emory University. Her broad research interests are examining the social processes that create and perpetuate racial and ethnic disparities in HIV. Her research has examined the intersection of individual level experiences of discrimination, macro-level neighborhood characteristics and social network relationships on high-risk drug and sexual behaviors. Dr. Crawford's research aims to inform structural interventions and policies that reduce substance use, high-risk drug and sexual behaviors, and ultimately racial and ethnic disparities in HIV. She received her PhD in Epidemiology from Columbia University’s Mailman School of Public Health. email:

Cam Escoffery, PhD, MPH, CHES is an Associate Professor in BSHE at RSPH.  She has an MPH from Emory University and a PhD from the University of Georgia in the area of health promotion.
