Prof. Ramaprakash's research interest is astronomical instrumentation. In the recent past, he has been largely involved in setting up the IUCAA Girawali Observatory, which has a 2m diameter optical, near-IR telescope and associated back-end instruments. He has also worked on CCD and near-IR detectors and data acquisition systems, cold optics and cryogenic design, testing and assembling, integral field units using optical fibres, OH-suppression spectroscopy, polarimetry etc. His observational interests relate to polarimetric studies of a range of astronomical sources such as pre-main sequence stars, brown dwarfs, galactic molecular clouds, and observations of transient phenomenae like GRBs and SNe.
