Dr. Tiro joined UT Southwestern as an Assistant Professor in the Department of Clinical Sciences’ Division of Behavioral and Communication Sciences in April 2008. She is also a member of the Harold C. Simmons Comprehensive Cancer Center and holds an adjoint appointment in the University of Texas-School of Public Health for the Dallas Regional Campus.

From 2005 until her move to UT Southwestern, Dr. Tiro was a Cancer Prevention Fellow at the National Cancer Institute (NCI). While there, she led a team of NCI and the Centers for Disease Control and Prevention (CDC) experts in designing several behavioral surveillance and health communication studies to evaluate the integration of the HPV vaccine into cervical cancer prevention and control.

At UT Southwestern, Dr. Tiro has led an interdisciplinary research team to examine patient-, physician-, and organizational factors associated with cancer prevention delivery at Parkland, the safety-net health care system for Dallas County.  Her team uses both quantitative and qualitative methods (electronic medical record (EMR) review, patient surveys, semi-structured interviews, focus groups, participant observation, document analysis, and hierarchical modeling) to identify potential intervention targets that address cancer health disparities.
