Dr. Krishnaprasad Chirakkil is a planetary scientist specializing in spacecraft data analysis and numerical modeling, focusing on planetary atmospheres, heliophysics, and space weather at Mars and Venus. He has expertise in analyzing in-situ particles and fields data, ultraviolet remote sensing, topside radar sounding, and modeling planetary exospheres and atmospheric escape, along with experience in spaceflight instrument calibration. His doctoral research addressed the impacts of space weather on Martian ionosphere, emphasizing solar energetic particle interactions and ion escape processes. As a postdoctoral researcher with the Emirates Mars Mission (EMM), he characterized Martian oxygen exosphere and nightside aurora using far-ultraviolet spectroscopy data and quantified oxygen escape rates with a 3-D Monte Carlo model integrated with MAVEN observations. Currently, Dr. Chirakkil is developing a vertically and horizontally coupled 2-D photochemical model for studying Venusian atmosphere and analyzing MAVEN EUVM solar occultation data to derive oxygen density profiles in Martian thermosphere. His research leverages data from multiple missions, including MAVEN, EMM, Mars Express, and the Mars Orbiter Mission, combining remote sensing and in-situ plasma observations.
