Welcome from the Interim Chair


Dear Visitor, 

I am pleased to welcome you to the Department of Microbial Infection and Immunity (MI&I) housed in the College of Medicine, within the Wexner Medical Center at The Ohio State University (OSU). The Department of MI&I was approved by the Board of Trustees in​ F​ebruary of 2011 and our research enterprise is located in the Biomedical 
Research Tower in the heart of the campus medical complex.

The Department of MI&I offers a broad range of research and teaching opportunities in a uniquely collaborative environment, where we focus on immunology and the study of host-pathogen interactions. In particular, MI&I has strengths in the study of microbial biofilms, drug/vaccine discovery, and innate and adaptive immunology/host defense. The fields of Microbiology and Immunology encompass many aspects of human health and a goal of our collective research is to further the basic understanding of the host-microbe interface and the immune system, as well as translate this knowledge into improvement of human health. Our robust population of students, faculty and staff has a passion for new discovery, as well as for training the next generation of scientists and health professionals.

Our Department is intricately linked to the newly founded Infectious Diseases Institute (IDI)​ at Ohio State, which links us to OSU researchers from across disciplines who also study microbes, immunology and infectious diseases, fostering collaborations and exchange of ideas. We also have close associations with several OSU programs/Departments including the Departments of Microbiology and Veterinary Biosciences, the Comprehensive Cancer Center​, the Davis Heart and Lung Research Institute, Centers located at Nationwide Children’s Hospital​, and the Ohio Agricultural Research and Development Center​.

Infectious diseases and immune disorders are among the major causes of morbidity and mortality in the US and worldwide. Our efforts to understand and prevent/treat these threats to human health drive our department personnel on a daily basis. As you browse through the MI&I website, I hope that you sense the excitement of our faculty, students, staff and fellows for scientific inquiry, their enthusiasm for their personal research programs, and the impact their work is having on society.
