About
Bio
Dr. Siddharth Krishnamoorthy is a Research Technologist in the Ionospheric and Atmospheric Remote Sensing Group and works on developing remote sensing technologies for Venus and Earth. He received his PhD in aeronautics and astronautics from Stanford University in 2017. Previously, he received a Master's degree in aeronautics and astronautics from Stanford University and a Master's degree in physics from the Indian Institute of Technology, Delhi, India. Siddharth’s main research interest lies in instrumentation, novel remote sensing techniques, and developing enabling technologies for planetary exploration. He has a diverse background in building, testing, and deploying software and hardware solutions to study complex multi-physics problems. He also served as a member of the Venus Exploration and Analysis Group (VEXAG) Steering Committee from 2021-2024.
