Research Interests:

Elizabeth's research is focused on the use of technology for health promotion. Health topics of most interest to her are obesity, physical activity, chronic disease and aging. Her research has included pro-anorexia websites, online cancer mailing lists for survivors and caregivers, and the effects of video games on energy expenditure and intake.

She is currently studying video games as a tool to increase physical activity and decrease sedentary behavior, the prevalence of behavioral weight loss tools in fitness video games and changes over time in active video game use in older adult women.

ErikDr. Erik Rytting
2005 PhD, The University of Kansas
2006-2008 Postdoctoral Fellow, Philipps-Universität Marburg, Germany
2008-2009 Postdoctoral Fellow and Instructor, University of Copenhagen, Denmark 2009-present Assistant Professor, UTMB Dept. of Obstetrics & Gynecology.

Research Interests:

Dr. Rytting's research lab is working to develop improved drug delivery strategies, with special emphasis on drug and nanoparticle transport across the placenta in order to address the needs of pregnant women requiring medical therapy or diagnostics, and to answer questions regarding the safety of medication during pregnancy in relation to fetal development.

Dr. Rytting conducted postdoctoral research to develop biocompatible nanoparticles for controlled drug delivery in the Department of Pharmaceutical Technology & Biopharmacy at Philipps-Universität Marburg, Germany.  He also received training in human placental perfusion techniques in the Institute of Public Health at the University of Copenhagen, Denmark. Other research projects have included in silico modeling to predict drug solubility, pharmacokinetic data analysis, nanotoxicology (safety assessment of nanomaterials), and the use of molecular biology techniques, hypoxia, and fluorescence to characterize the expression and function of drug transporter proteins in the placenta.
