About Us
We are an interdisciplinary, multi-institutional group of scientists, led by Rajdeep Dasgupta of Rice University, Houston, TX, working to unravel the conditions of planetary habitability in the Solar System and other exoplanetary systems. The overarching theme of our research is to investigate the origin and cycles of life-essential elements (carbon, oxygen, hydrogen, nitrogen, sulfur, and phosphorus – COHNSP) in young rocky planets. Based on our understanding of our own solar system and habitable planet Earth, we plan to identify where habitable niches are most likely to occur, which planets are most likely to be habitable and when in their evolutionary history such conditions of habitability are most likely. We are supported by NASA and are one of teams in the Nexus of Exoplanetary Systems Science (NExSS) research network
