Dr. Inbarasan Muniraj

Assistant Professor

Alliance College of Engineering and Design

Dr. Inbarasan Muniraj holds a Ph.D. in Optical Engineering and M.E. degree in Computer Engineering and B.E. degree in Electronics and Communication Engineering from University College Dublin, Ireland (UCD), Chosun University South Korea, and Anna University Chennai, respectively. He worked as research scientist in Gwangju Institute of Science and Technology, South Korea. His Ph.D. was sponsored by the Government of Ireland under Postgraduate Scholarship Programme (IRC). After a yearlong postdoctoral research experience from UCD, he worked for Intel Corporation in Ireland on a few different roles.

Research interests of Dr. Muniraj are developing non-invasive imaging systems for biomedical applications and also instrumenting low light level (photons counting) imaging systems for various imaging modalities such as 4D light field imaging, holography, and holographic microscopy. He has authored over 40 publications in the peer-reviewed reputed journals and conferences. He also authored a book in SPIE spotlight series and an inventor of two Indian and one US Patents.
