Srirang Manohar is Adjunct Professor, Biomedical Photonic Imaging. He has pioneered research into photoacoustic imaging of breast cancer. He also investigates the feasibility of the method in imaging inflammation in joints in rheumatoid arthritis. Prof. Manohar’s research spans technology development to early clinical assessment. The intended applications of the technologies span the range of ex vivo tissue imaging, minimally invasive imaging to non-invasive. He has also done investigations into synthesis and characterization of gold nanoparticles, and in vitro and in vivo application of these and iron oxide nanoparticles in the context of providing contrast for photoacoustics.
Prof. Manohar is the coordinator of the H2020 project, PAMMOTH running from 2017-2021. He is member of the Organizing Committee for the conference “Photons plus Ultrasound: Imaging and Sensing held annually under auspices of SPIE (Photonics West, San Francisco, USA). He is also member of the Program Committee for the conference Opto-Acoustic Methods & Applications, European Conferences on Biomedical Optics (ECBO), Munich, Germany.
Biomedical imaging specifically photoacoustic imaging for non-invasive and minimally-invasive detection and diagnosis of various pathologies including breast cancer and rheumatoid arthritis;
Molecular medicine spanning the trajectory from synthesis, characterization, minimizing cytotoxicity to preclinical applications of antibody conjugated gold nanoparticles for photoacoustic imaging and photothermal therapies.
