Research Interests

Dr. Ch. Mohan Rao combines biophysical, molecular biological and cell biological approaches to address problems of biomedical importance. His research interests include protein folding, molecular chaperones and heat shock proteins, molecular basis for lens transparency, cataract and keratitis; DNA based diagnostics, Nanobiology, Photoacoustic spectroscopy and its application to biomedical problems. His recent research addresses role of small heat shock proteins in gene expression, cell division, differentiation and apoptosis.
