Dr. Bhat's research interest is focused on understanding intricacies of a complex bacterial system, Myxococcus xanthus, which require a multidisciplinary approach. M. xanthus is a Gram-negative bacterium. It is a wonderful prokaryotic system to understand multicellular development. During vegetative stage, M. xanthus cells swarm together while feeding on other bacteria. Upon starvation, M. xanthus cells aggregate to form fruiting bodies. Inside a fruiting body, rod-shaped cells undergo cellular morphogenesis to form spherical myxospores. M. xanthus fruiting body development is governed by cell-cell signaling. The identities and roles of many of these signals remain unknown. As part of Dr. Bhat's Ph.D. thesis and post-doctoral research, Dr. Bhat's projects involved understanding cellular signaling during fruiting body development.
