Ishan Barman is an Associate Professor in the Department of Mechanical Engineering at Johns Hopkins University with joint appointments in the Departments of Oncology and Radiology and Radiological Science. He graduated from the Indian Institute of Technology (IIT), Kharagpur, before moving to Massachusetts Institute of Technology (MIT) for his M.S. and Ph.D. During his doctoral research, he investigated non-invasive blood glucose sensing using vibrational spectroscopy under Professor Michael Feld. He leads an interdisciplinary research group that is focused on the development of cutting-edge biophotonics technologies with the goal of disease detection at early, manageable stages, monitoring therapeutic effects and treatment outcomes, and guiding interventions. The optical tools generated from these investigations have been leveraged in diverse biomedical environments including in automated recognition of biopsy specimen, real-time diagnosis of middle ear pathology, and as a customized monoclonal antibody identification platform.
