Helen Yin, Ph.D.

Dr. Yin's research is focused on regulation of the actin cytoskeleton and membrane trafficking. She discovered gelsolin, the first actin filament severing protein, in 1979. Gelsolin is regulated by calcium and the lipid phosphatidylinositol 4,5 bisphosphate (PIP2). She elucidated the roles of the lipid kinases that  synthesize PIP2 and its precursor, PI4P, in response to hypertonic and oxidative stress, during membrane signaling, phagocytosis and autophagy. Her research improves understanding of these essential lipids’ roles in cell survival, organelle remodeling, membrane trafficking, and autophagy.

Dr. Yin is a strong advocate for translational science. She created the UT Southwestern “Mechanisms of Disease & Translational Science” graduate track in 2008. This track uniquely exposes PhD students to clinical and translational research, so that they can target their future research to address unmet diagnostic and therapeutic needs. This PhD track was initially supported by the Howard Hughes Medical Institute “Med into Grad” Initiative, and is currently supported by an NIH Molecular Medicine T32 Institutional Training Grant. Dr. Yin has also been the co-director of the Education and Career Development Program of the UT Southwestern Center for Translational Medicine (supported by a Clinical and Translational Science Award ) since 2012. She was elected as a University of Texas System Distinguished Professor in 2014, and won the System's Academy of Health Science Education’s Innovator Award in 2015.

In addition to her scientific and education roles, Dr. Yin has been the Inaugural  Associate Dean for the Office of Women’s Careers since 2012.  In this role, she collaborates with the Office of Faculty Diversity and Development to advocate for our faculty, with particular focus on women and diverse faculty. In 2013, she co-created the "Leadership Emerging in Academic Departments" (LEAD faculty leadership program). In 2015, she co-created the multi-tiered "Successfully Obtaining an R" (SOAR) grantsmanship program. She directs the highly successful "SOAR Intensive R Grant Writing Workshops" that has improved our faculty's extramural grant funding success.  Dr. Yin was active in the UT System as the founding chair of the UT System Senior Women Leaders Sponsorship Workshop in 2016, and was s a member of the UT System Chancellor’s “Quantum Leap Initiative” on Gender Pay Equity. She was on the national program planning community for the 2017 Summit on “Inspiring Intersections: A Call to Collaborate, Challenge, and Change” that was co-sponsored by the AAMC Group on Faculty Diversity and Inclusion and Group on Women in Medicine and Science. She is a member of Steering Committee of the AAMC Group on Women in Science and Medicine. Dr. Yin is also active in increasing diversity, equity and inclusion at UTSW.
