The Department of Earth and Planetary Science at the University of California, Berkeley seeks applications for an Assistant Project Scientist in the area of Atmospheric Science, specifically Cloud Physics, using Stereophotogrammetry, Remote Sensing, and Computational Modeling to study moist convection, with strong emphasis on instrument development (cameras), data processing (calibration, stereo reconstruction algorithms), scientific leadership, and mentorship in physical sciences.

This position will be in David Romps' group in the Earth and Planetary Science Department of UC Berkeley. The group at UC Berkeley and Lawrence Berkeley National Laboratory (LBNL) uses theory, simulation, and observation of clouds and atmospheric dynamics to improve our understanding of Earth's climate.

The successful candidate will co-lead the development of cameras for the stereophotogrammetry of clouds, combining the camera data with the theory of physical processes and related numerical simulations to answer scientific questions about moist convective dynamics.

Assist with supervising and mentoring postdocs, graduate students, and undergraduate students. The Assistant Project Scientist will collaborate with David Romps' group to produce publications, as well as contribute to proposals and progress reports. Maintain the code base responsible for camera calibration, feature matching, stereo reconstruction, and volume filling. Develop new stereo-reconstruction algorithms to keep our program at the cutting edge of cloud photogrammetry. Manage the operations of the cameras, including calibration, maintenance, and troubleshooting.
