Bio Statement

Dr. Marcel de Dios is an assistant professor in the Department of Health Disparities. My programmatic line of research focuses on developing and testing smoking cessation treatment interventions for ethnically diverse and vulnerable subpopulations, particularly Latinos. I completed my T32 post-doctoral fellowship in Behavioral Medicine at Brown Medical School. During my fellowship, I worked on an NCI funding clinical trial that aimed to develop and test a smoking cessation intervention for HIV+ Latinos (Project AURORA, PI Niaura). Upon completing my fellowship at Brown, I was promoted to the faculty at Brown and obtained funding from the NCI to conduct a supplemental study focusing on examining the unique social support and social network characteristics of methadone maintenance patients enrolled in a smoking cessation trial (Project QUIT, PI Stein). Through both of these projects I became keenly aware of the challenges of treatment adherence to smoking cessation treatment among diverse and vulnerable subpopulations. I also recognized the need for integrating mixed methodologies when pursuing such research particularly qualitative methodologies. Subsequently, I submitted and was awarded an NCI K01 proposal that aims to develop and test an intervention that enhances adherence to smoking cessation treatments among Latinos and also provides advanced training in higher level qualitative methods as well as the use of technology in health care delivery. In October of 2012, I transitioned my program of research to the Department of Health Disparities Research at the University of Texas MD Anderson Cancer Center which continues to offer an ideal research context for studying Latino smoking cessation and pursuing my program of research.
