The Department of Immunology and Microbiology encompasses a broad range of research and teaching activities focused on basic mechanisms of host immune responses, mechanisms of viral and bacterial pathogenesis, and the intersection of these two domains in studies of host-pathogen interactions. To complement our basic studies on molecular and cellular mechanisms, we aim to collaborate with our clinical colleagues on the CU Anschutz Medical campus to apply our research expertise into investigations of infectious diseases, autoimmune diseases, tumor immunology, primary immunodeficiencies, and chronic inflammatory conditions. The importance of strong basic research in Immunology and Microbiology has never been more apparent, as the world struggles to recover from the COVID-19 pandemic, caused by a novel coronavirus, SARS-CoV-2. The devastating global effects of this pandemic highlight the need to strengthen our investigations into viral and bacterial pathogens, the immune response and our ability to manipulate it for therapeutic interventions. Perhaps most importantly, we are now even more motivated to invest in training the next generation of immunologists, virologists, and microbiologists.
