Robin J. Leach, Ph.D.
Department of Cell Systems and Anatomy
Associate Director for Education, Mays Cancer Center
Currently seeking M.S. & Ph.D. students
Research in Dr. Robin Leach's laboratory focuses primarily on urologic cancers including prostate, bladder and testicular. For prostate cancer, the work centers on identify better markers for progression and outcome, with the long term goal of developing biomarkers that will assist clinically in distinguishing between indolent versus aggressive disease. In addition to the prognostic marker work, Dr. Leach's laboratory works to validate existing biomarkers for prostate cancer with the goal of utilizing them in informed decision making. For bladder cancer, the effort is focused on determine the effects of obesity on bladder cancer progression; this work could ultimately lead to new therapeutic approaches for treating bladder cancer. Dr. Leach is a molecular geneticist by training and has worked on the genetics of several complex diseases. Recently, this work has been expanded to project in pharmacogenetics and health disparity. In addition to her primary research, she oversee the Mays Cancer Center Biobank and the Biobank and Genome Analysis Core for the Institution. She is also the Associated Director for Education for the Mays Cancer Center and in this role, oversee their Office of Education.

Funding Agency National Institutes of Health Title San Antonio Cancer Institute Status Active Period 9/1998 - Present Role Co-Investigator Grant Detail To identify the cultural, economic, and structural barriers to early phase clinical trial participation faced by patients and oncologists, and to develop effective interventions to reduce these barriers, thereby increasing participation in drug development trials. Funding Agency National Institutes of Health Title San Antonio Cancer Institute/CTRC Status Active Period 9/1998 - Present Role Principal Investigator Grant Detail The CTRC (formerly San Antonio Cancer Institute) is an NCI-designated cancer center. Dr. Leach directs the Genomics core facility which offers genotyping, gene expression, and biobanking. Funding Agency NIH Title Cancer Therapy and Research Center (Genetics Resource Core) Status Complete Period 9/1999 - 7/2018 Role Co-Investigator Grant Detail Funding Agency NIH/NCI Title The Cancer Bioinformatics Initiative: A UTSA/UTHSCSA Partnership (1 of 2) Status Complete Period 9/2012 - 8/2017 Role Principal Investigator Grant Detail This is a partnership between quantitative scientist at UTSA and cancer biologist working on health disparity at UTHSCSA. The goal is to develop curriculum in bioinformatics for the quantitative scientist at UTSA, provide summer internships for students in those disciplines at UTHSCSA plus educational opportunities for biologist at UTHSCSA to gain expertise in analyzing big data.
Dr. Leach serves on a number of departmental committees including the teaching award committee and student award committee. In addition, she is a member of the PTAC and PTEC for the Department of Cell System and Anatomy.
Dr. Leach is the Associate Director for Education for the Mays Cancer Center. In this role, she is involved in managing the summer cancer research programs that are offered for students from high school to master's level. In addition, she oversee the Office of Education for the Cancer Center. She is also a founding member of the Academy of Educational Scholars.
Dr. Leach oversee the institutional Biobanking and Genome Analysis Core. She has been an institutional core director since 2000.
Dr. Leach has served as an ad hoc member as well as a regular study section member for numerous NIH committees including Cancer Genetics and Health Disparity Research Committee for the National Cancer Institute. In addition, she is a regular reviewer for the CDMRP program sponsored by the Department of Defense. In this role, she has participated in over 40 study sections, and has chaired more than half of these.
