My research is focused on regulation of the actin cytoskeleton and membrane trafficking by the phospholipids phosphatidylinositol 4,5 bisphosphate (PIP2) and phosphatidylinositol 4 phosphate (PI4P). I elucidated the roles of the lipid kinases that generate PIP2 and PI4P in response to hypertonic and oxidative stress, during membrane signaling, phagocytosis and autophagy. My contributions improve understanding of these essential lipids’ role in cell survival and organelle remodeling, membrane trafficking, innate host response and inflammation.


I am a strong advocate for translational science, as evidenced by my creation of the UT Southwestern “Mechanisms of Disease & Translational Science” graduate track in 2008 and my role as co-director of the “Education and Career Development Core” of the UT Southwestern Clinical and Translational Science Award (CTSA) since 2011. The Mechanism of Disease and Translational Science graduate track will train PhD students with a foundation in the molecular basis of disease, and will increase their ability to target their research to address unmet diagnostic and therapeutic needs. This PhD track has been supported by the Howard Hughes Medical Institute “Med into Grad” Initiative and by an NIH Molecular Medicine T32 Institutional Training Grant. I was elected as Distinguished Professor by the University of Texas System in 2014, and won the University of Texas Academy of Health Science Education’s Innovator Award in 2015.


In addition to my scientific and education roles, I am also the Associate Dean for the Office of Women’s Careers. In this role, I advocate for our faculty, with particular focus on women and diverse faculty. I am active in the University of Texas System’s “Quantum Leap Initiative” as a member of the Committee for Gender Pay Equity and Committee on Women Leadership Development. I am on the national program planning community for the upcoming Summit on “Inspiring Intersections: A Call to Collaborate, Challenge, and Change” that is co-sponsored by the AAMC Group on Faculty Diversity and Inclusion and Group on Women in Medicine and Science.
