Research Statement

Dr. Chowdhury, a distinguished researcher, is deeply committed to exploring the intricate facets of immune cells within a broad range of infectious and inflammatory diseases. His journey at Washington University’s Department of Molecular Microbiology began in 2019, where he collaborated closely with Professor Christina Stallings, resulting in a significant discovery. Together, they unveiled the crucial role of Neutrophil Extracellular Traps in promoting the pathogenesis of Mycobacterium tuberculosis. Dr. Chowdhury’s expertise also played a pivotal role in drug development projects focused on the application of NETosis inhibitors for tuberculosis treatment. As an Instructor within the Department of Pathology and Immunology, Dr. Chowdhury’s dedication is firmly directed towards unraveling the mechanisms governing immune and cancer cell death. He possesses a keen interest in investigating the role of cell death pathways in disease resolution and their profound impact on the immune landscape during both disease progression and therapeutic interventions. Dr. Chowdhury, alongside his esteemed team, embarks on in-depth investigations into the fundamental process of cell clearance within the context of immune therapy. His ultimate goal is to discover novel and supportive treatment approaches that will elevate patient care and enhance the effectiveness of existing treatments. With a passion for transformative research and a commitment to advancing medical science, Dr. Chowdhury’s work at Washington University embodies a drive to make a meaningful impact on the understanding and treatment of infectious and inflammatory diseases.
