The Training Program in Integrative Membrane Biology is an elite program designed to train doctoral students in the physiology, biophysics, biochemistry, structure, and cell and molecular biology of biological membranes. Support for this training program has been provided from a training grant, now starting its 31st year, from the Systems and Integrative Biology program within the National Institute of General Medical Sciences (NIH).

The central idea motivating the program is that biological membranes, and especially plasma membranes, are the arbiters and integrators of a cell's response to its environment. Trainees select from a menu of basic courses in biochemistry, molecular and cell biology, physiology and neuroscience, and, in addition take specialized courses in membrane biochemistry, biophysics and integrative biology. These foundation courses place special emphasis on the structure and function of membrane macromolecules and the ways in which they control membrane permeability and cellular function.

The program is an interdepartmental program but does not grant a degree. Instead, students receive degrees from the programs in which they are enrolled. The Graduate Program in Life Sciences' programs that participate in our training program include: Biochemistry & Molecular Biology, Molecular Medicine, Neuroscience and Molecular Microbiology & Immunology.

Our Campus

The University of Maryland School of Medicine is on the campus of the University of Maryland, Baltimore (UMB), located on the west side of downtown Baltimore. UMB consists of six other professional schools, including the Graduate School, and the schools of NursingPharmacyDentistrySocial Work and Law.

Student Research Series

November - July
Fridays at Noon
Rm 450 Howard Hall
(lunch provided)

The Program in Membrane Biology organizes an interdepartmental and interdisciplinary series of talks, "by and for" students. This seminar series is for students in ALL programs, not just those affiliated with the Membrane Biology program. The idea is to keep you all informed of the nature of the research you and your colleagues are doing, in all the "bench" sciences in the School of Medicine. Talks are presented by students who have made significant progress in their dissertation research. Faculty are welcome to attend at the invitation of the speaker, but only students in the audience may ask questions during the presentation. Many students have found this a useful venue to present their work in preparation for national meetings, departmental talks, or thesis proposals.

If you would like to present your research, there are still slots open for the summer sessions. Please email to sign up!

Course Work

Foundation Courses

The TPIMB curriculum buildson two foundational courses for all UMSOM Graduate Students (Mechanisms in Biomedical Sciences: From Genes to Disease (GPLS 601) and Research Ethics (GPLS 901). In the second year, TPIMB students are required to take a unique series of upper level courses on membrane biochemistry and biophysics (Ion Channels; GPLS 625), on links between membrane defects and human diseases (Topics in Molecular Medicine; GPLS 750), and rigor and reproducibility (Fundamentals of Biostatistics; GPLS 630). Enhanced training is provided as trainees participate regularly in student-oriented activities, such as a student-only research seminar series, monthly get-togethers, an annual retreat, peer mentoring, coordinating visiting endowed lectureships and alumni networking.

Core Course

GPILS 601 Mechanisms in Biomedical Sciences: From Genes to Disease (8 credits) This course offers a comprehensive overview of current knowledge in cellular, molecular, and structural biology and provides the background necessary for subsequent specialized studies in biomedical research for students in the programs in Neuroscience, Molecular Medicine, and Biochemistry and Molecular Biology.

The format of this course is highly interactive, and includes:

  • Lectures presenting creative, cutting-edge approaches to investigating fundamental, current biomedical questions, together with review of fundamental principles of molecular and cellular biology
  • Vertically-integrated topics that tie together the study of individual genes, proteins, cellular function and associated clinical disorders
  • Emphasis on development and critical evaluation of scientific hypotheses
  • Introduction to state-of-the-art techniques
  • Mentored discussions of primary papers
  • Topic-specific seminars, including cancer, neuroscience, membrane biology and gene therapy
  • Optional, supplemental review sessions prior to each topic to strengthen background knowledge
    Course Director: Dr. Rick Matteson

GPLS 625 Ion Channels (2 credits) This 2-credit course will prepare students for advanced study and laboratory research on the structure and function of ion channels. In this primary literature-based readings course, topics include the biophysical mechanisms by which ion channels open and close to regulate ion conduction, structural basis for ion channel function based on high resolution x-ray crystallography, and specialized mechanisms that tune ion channels for their physiological roles. Major channel families and synthetic channels (channelrhodopsin) will be covered. The course will include a discussion of the diverse roles played by ion channels in human diseases (channelopathies). Prerequisites: GPLS core course or consent of the course directors. Offered yearly in the spring semester. Course Directors: Dr. Andrea Meredith and Dr. Matt Trudeau

GPLS 630 Fundamentals of Biostatistics, Hypothesis Testing and Experimental Design (3 credits) This course is designed to prepare students to understand and apply hypothesis testing, sound experimental design and statistical methods in order to perform and evaluate biomedical research. The course uses a ‘flipped’ design model, where learning objectives, videos prepared by faculty, links to other on-line instructional videos, problem sets, and self-assessments are on-line and completed prior to in-class sessions. Weekly sessions are then devoted to answering student questions, review of problem sets, and discussions of examples appropriate to the week’s topic. For complex problems, students work in groups and use software to arrive at answers, which are then shared with the group. Topics are specialized for specifically for the biomedical sciences and include, Hypothesis Testing, Experimental Design, Probability Distributions, ANOVA, Regression and Correlation, and non-parametric statistics.

GPLS 750 Topics in Molecular Medicine (2 credits) This course is aimed at developing skills necessary for understanding and discovering how changes in gene function cause human disease. The course focuses on inherited disease processes that illustrate the physiological consequences of molecular, cellular, genetic phenomena. Recent breakthroughs in the identification of disease-related genes are presented and extended to a discussion about their impact on cell and organ function. Critical reading and discussion of landmark and/or timely papers are stressed. In this way, students learn interesting state-of-the-art material while developing skills and expertise in integrative biology and molecular medicine. Topics change yearly, but have included: paralysis, malignant hyperthermia, cardiac arrhythmias, congestive heart failure, glomerulitis-Alport's, cystic fibrosis, Liddle's syndrome, hyperinsulinemia of infancy, type II diabetes mellitus, influenza, migraine headache and neurogenic inflammation, and Duchenne dystrophy. Two or three one-hour classes per topic consist of interactive discussions following assigned readings and brief lectures. Offered yearly in the fall semester.

Student Research Seminar Series (SRSS) All TPIMB students are required to participate in the student-led works-in-progress seminar, held weekly from early November through the end of June. Seminars are 45 mins and are presented by, and open to, GPLS students from any program (mostly Molecular Medicine, Neuroscience, Biochemistry and Molecular Biology, or Toxicology, with occasional talks by students from Epidemiology, Microbiology and Immunology and Bioengineering). Lunch is provided. Presenters take questions from other students preferentially, and faculty may attend (some students use their talks as a means of updating their thesis committees) but are not permitted to ask questions until all students questions have been answered.

Specialized programs of course work are drawn from the menus of classes offered by the participating graduate programs within the Graduate Program in Life Sciences at UMB:
