Pathology, Microbiology and Immunology

Our department is responsible for teaching medical and graduate students and house multidisciplinary research programs. Our research programs are led by investigators who are supported through extramural research funding. Our output is reflected through various per-reviewed publications and presentation at various scientific meetings globally by our faculty, fellows and students.

Our Faculty

Our faculty specialize in various areas of biomedical research and run successfully funded research programs in diverse areas. They teach medical students and graduate students and serve on various institutional committees. Our faculty are appointed to various grant review committees, hold office at various national and international societies and editorial boards.

Facilities and Resources

Our faculty direct state-of-the-art cores such as the Flow Cytometry and Sorting.  Our other shared resources comprise cutting-edge equipment and technology for Advanced Microscopy, –Omics (Genomics, Epigenomics, Transcriptomics and Microbiome technology) and Metabolic Profiling studies. We welcome you to visit us to see our equipment and resources first-hand.

Medical Education

Our department is actively involved in teaching Pathology, Medical Microbiology, and Immunology to our medical students in the M2 year.  Our faculty are engaged in teaching various lectures in the new integrated systems-based curriculum for our second-year medical students. We utilize a combination of didactic teaching, active and team-based learning approaches.

This graduate level course covers immune system components, including the innate and adaptive immune system, their functions and interactions.  Topics on immune system dysregulation and consequences as related to disease and health are included.  Current topics of interest in immunology also are covered. Overall, students will gain an advanced understanding of the immune system.

By the end of this course the student will demonstrate knowledge and understanding in:

  1. the components of the immune system and their functions.
  2. interactions between immune system components.
  3. immune system dysregulation and consequences.
  4. immune response during health and disease.

This course is offered in Fall and Spring semesters, primarily to graduate students who have a background in basic Immunology. The format of the course is as a journal club wherein 2-3 papers will be discussed on a weekly basis on current immunology literature that has appeared in high-impact journals like Science, Nature, Nature Medicine, Nature Immunology, Proceedings of the National Academy of Sciences, USA, Journal of Experimental Medicine, Journal of Immunology, Cell and Immunity.

The scientific paper discussion will include Introduction, Materials and Methods, Results, Discussion and Bibliography. One of the most important aspects of this course is to train the student to critique research and to improve the quality of their research by incorporating novel concepts and techniques.

This course is designed to provide graduate students with a fundamental biomedical knowledge base in human pathology and an introduction to the study of the disease process. Particular emphasis will be given to the etiology, pathogenesis and description of gross and microscopic pathologic patterns occurring during the progress and outcome of major human diseases and conditions.

Students will be introduced to the experimental approach of the development and subsequently effective treatment of certain diseases, through the description of animal models simulating related pathologies. With the knowledge of normal histology, and by gaining familiarity of microscopic appearances through a hands-on experience at the lab small groups, students will develop observational and descriptive skills and ultimately deepen their understanding of the underlying mechanisms of disease. By the description of the experimental methodologies, including the murine models of various diseases, they will formulate the causative approach in the study of disease.
