I study the atmosphere of Mars and Venus focusing mainly on energetics and dynamics via measurements and models, focusing on the coupling between the lower and upper atmosphere and its effect on the overall evolution of the upper atmosphere temperatures and densities. During my PhD, I developed a unique electron degradation technique for the Martian atmosphere based on a Monte-Carlo model. Using this technique, I predicted the Ultraviolet dayglow emissions on Mars, Venus, Titan, and Pluto. I have been developing/refining my aeronomy model to understand the ultraviolet emissions emanating from the planetary atmospheres and the role of solar EUV flux in planetary escape processes. I continue to study the Martian dayglow using measurements by MAVEN (Mars Atmosphere and Volatile EvolutioN mission) ultraviolet (UV) spectrograph after joining the Laboratory for Atmospheric and Space Physics (LASP), University of Colorado at Boulder, Colorado, and trying to understand the Martian thermo- sphere dynamics and energetics. Being one of the core members of the Imaging Ultraviolet Spectrograph (IUVS) onboard MAVEN LASP, CU, Boulder, I play an important role in supporting the scientific analysis of the IUVS data and its performance. I have been involved in the scientific analysis of IUVS data and collaborating with other IUVS and MAVEN team members and researchers interested in IUVS data. I am a member of the MAVEN Science team and the Emirate Mars mission (EMM) UV spectrograph science team at LASP.
