The lab has two full-time registered vascular technologists, and a research lab manager. The technologists are trained and certified in all testing procedures provided by the laboratory. The URL has developed and completed multiple training programs and methods of operation manuals for CIMT and PWV protocols for multiple epidemiological studies across the country. The lab provides both onsite and offsite continuous quality control analysis for active studies within the URL. Additionally, the URL trains both pre- and post-doctoral students within the Graduate School of Public Health in all areas of CIMT, PWV and endothelial testing methods.

URL Director

Dr. Barinas-Mitchell is Associate Professor in the Department of Epidemiology and serves as Director of the URL. She served as Associate Director of the URL, from 2007 to 2012. She has collaborated on more than 20 NIH, ADA and AHA funded projects in the application of subclinical vascular measures in the study of CVD prevention and development. Furthermore, during this time she has been actively involved in research investigating the role of obesity and related cardiometabolic disturbances in the development and progression of subclinical CVD, primarily as a co-investigator on the SWAN (U01 AG012553) longitudinal study of women through the menopausal transition and the weight loss intervention SAVE study (R01 HL077525). For both of these studies, Dr. Barinas-Mitchell was responsible for supervising the data collection, quality control, data management and interpretation of the subclinical vascular measures, including carotid IMT and AD and aortic PWV. For the past 10 years she has mentored several pre- and post-doctoral trainees as Co-Director of the Cardiovascular Training Grant. She has also mentored students via the Department of Epidemiology 2152 course Student Workshop in CVD, which she has taught since 2008 as assistant instructor and since 2012 as lead instructor.
