Microbiology & Infectious Diseases

Welcome to the Microbiology & Infectious Diseases PhD graduate program. Our location in the Texas Medical Center, the world’s largest biomedical center, provides an excellent research environment.

The biological sciences have undergone a revolution of unprecedented scale. This revolution, fueled in large part by studies in microbiology, is fast reshaping the way scientists approach the myriad of biomedical and environmental issues confronting our society today. At the same time, microbiology still maintains its classical advantages – a wide variety of well-developed experimental approaches are available in the study of microbes, and many experiments can be completed in a relatively short time period. This makes microbiology especially well-suited for graduate student training. Our program faculty explore questions relevant to the following areas of modern microbiology:


Fundamental Life Processes

Many genes and their activities are conserved among bacteria, archaea, and eukaryotes. Our faculty exploit the many practical advantages of microbes to perform detailed mechanistic studies of a wide array of fundamental biological phenomena. These include gene expression, cell division, membrane biogenesis, macromolecular transport, multicellular development, and cellular differentiation.

Microbial Pathogenesis

Understanding virulence mechanisms is a major arm of medical research. Our faculty apply modern molecular genetic and biochemical technologies to understand the basis for infectious disease. Emphasis is placed on identifying and characterizing regulatory networks controlling virulence gene expression, virulence factor structure and function, mechanisms for spread of antibiotic resistance, and the host-pathogen interactions.

  • Activities

    MID Retreat
    A shared retreat with the Microbiology & Molecular Genetics department, a yearly retreat with MID program students, departmental post-docs, and faculty attend an out-of-town retreat. At the retreat, students present their research results and ideas. Also, a keynote address is delivered by an outside speaker. In addition to the scientific aspect, the retreat is a great chance for students and faculty to relax and have fun together.

    MID Journal Club
    We have a very active journal club in which our students, department post-docs, and faculty discuss particularly interesting and timely papers pertaining to microbiology and/or infectious diseases.

    MID Student Summer Seminar Series
    During the summer our journal club is replaced by our student seminar series. These seminars give students in the Microbiology and Infectious Diseases program the chance to practice their presentation skills, and to get constructive feedback on their research.

    MID Student Colloquia (GRASS)
    Once a month one of our graduate students presents his/her research objectives and results to the other graduate students. This voluntary get-together is organized by the students themselves, and provides a great opportunity to practice presenting and get constructive feedback in an informal setting.

    Microbiology and Molecular Genetics Departmental Seminars
    In the departmental seminar series, outstanding scientists from around the world present their research Thursdays at 10:30 am. Click here for the latest event listings.

    Topic-specific meetings within the Texas Medical Center
    Many MID students participate in regular meetings of scientists from all of the TMC institutions who share common research interests. Many such groups meet, including the TMC chapter of the American Society for Microbiology, the Molecular Basis of Infectious Diseases group (MBID), the Fungi/Fungal group, the Bacterial Interest Group (BIG), a C. elegans group, and many others. This provides MID students with a unique opportunity to take advantage of the wealth of knowledge and experience found in the many research institutions in the TMC.

  • Program Bylaws

    I.   Introduction and Mission 

    The goal of the Microbiology and Infectious Diseases (MID) Program is to promote scientific excellence by providing intense and modern student training in microbial model systems and the molecular basis of microbial pathogenesis. Microbes are especially well suited for graduate training because their inherent rapid growth and availability of a wide variety of approaches allow an individual student to make a significant contribution to scientific understanding. Most of the existing knowledge of molecular and cellular biology is based on analysis of microbial model organisms. Microbes also are responsible for a wide variety of infectious diseases that affect every single human during their lifetime and cause significant morbidity and mortality. This focus on microbial systems is unique within the UT MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences (GSBS). The Program functions in cooperation with the GSBS. Program faculty are members of the GSBS and are expected to be full participants in GSBS activities.
