    Research Environment

    The UTSA Department of Chemistry is ranked highly by Nature Index among all chemistry departments in the United States. The Department provides NMR, Mass spectrometry, and other shared facilities to all the research groups without or with minimal charges. For details, please see and


    The Department of Biology, located in the same BSE building, has research strengths in the following areas: Cell and Molecular Biology, Microbiology and Immunology, Neurobiology, and Plant Biology.


    The BSE building also hosts multiple research centers and institutes related to our research and provide seminars as well as research resources to us as we need. These include Center of Excellence in Infection Genomics (CEIG), Neurosciences Institute, San Antonio Cellular Therapeutics Institute (SACTI), and South Texas Center for Emerging Infectious Diseases (STCEID).


    The University of Texas Health Science Center (UTHSCSA) at San Antonio is a high-level education and medical research center located in the medical district of San Antonio, about seven miles from our laboratory. UTHSCSA is the most significant health sciences campus in South Texas with M.D./Ph.D. programs and research hospital as well as patient care. We have partially overlapping research interests and collaborations with the faculty of Departments of Biochemistry, Cellular & Structural Biology, Microbiology & Immunology, Molecular Medicine, Pharmacology, and Physiology.
