Dr. Ratheesh Kumar Meleppat

Dr.Ratheesh K. Meleppat received his Ph.D. in optical imaging from Nanyang Technological University (NTU) Singapore. He completed his Bachelor’s degree (B.Tech) in Electronics & Communication Engineering from University of Calicut, India and Master’s Degree (M.Tech) in Optoelectronics & Optical communication from the University of Kerala, India.
Dr.Ratheesh is currently a Research Scientist at University of California Davis (UC DAVIS),USA. His research investigates the novel cutting-edge biomedical instrumentation and image processing schemes for the advanced ophthalmic imaging and applications. The primary focus on the instrumentation research is the development and use of imaging technologies such as Optical Coherence Tomography (OCT), OCT Angiography (OCTA), Scanning Laser Ophthalmoscope (SLO), Multispectral Fluorescent microscopy, Adaptive Optics (AO), and their combinations to study the retina noninvasively at the cellular level. Research focuses on the implementation of novel algorithms based on graph theory, ML/AI for the analysis of in vivo and ex vivo retinal data acquired using different imaging modalities. Research also investigates these technologies to determine their usefulness in retinal diagnostics, the study of disease processes, and the testing of new drugs and therapies in pre-clinical animal (mouse) models.
He serves as an active member of the Society of Photo-Optical Instrumentation Engineers (SPIE),The Association for Research in Vision and Ophthalmology (ARVO),Institute of Electrical and Electronics Engineers (IEEE) and IEEE Photonics Society and the Indian Society for Technical Education (ISTE).
