My background is in Computer Science, Planetary Science, and
Geology. I am most interested in problems that lie at the interfaces
between these fields, such as automated methods (artificial
intelligence, machine learning) to investigate science questions using
planetary data (orbital and in situ).
I work at the Jet
Propulsion Laboratory in Pasadena, CA, as a researcher in the
Machine Learning and Instrument
Autonomy Group, investigating ways that machine learning can be
used to increase the autonomy of space missions.
From 2013 to 2017, I also served as a
tactical planner and uplink lead for the
Mars Exploration Rover Opportunity. Since 2018, I have also served
as the PDS Imaging Node
I am also an Associate Research Professor at Oregon State University,
where I have the pleasure of
teaching classes in Computer Science and doing research on competency-aware machine learning.
My research projects at JPL have included:
- Onboard science for Europa Clipper: Developing and testing methods
to quickly analyze data as it is collected during a flyby of Europa to
assign high downlink priorities to the most scientifically valuable
observations and to enable cross-instrument collaboration
- Mars Target Encyclopedia: Information extraction from scientific
publications for planetary science
- V-FASTR: Efficient machine learning to detect transient radio phenomena (e.g., pulsars and Fast Radio Bursts) in real time
- Collaborative machine learning for sensor networks
- Automatic landmark identification and change detection in Mars orbital images (dark slope streaks, dust devil tracks, etc.)
- Analyzing the sensitivity of machine learning algorithms to high-radiation environments
- Predicting county-level crop yield from Earth orbital images
- Modeling user preferences for sets, rather than individual items
(like music playlists or rover image downlink sets)
- Modeling flight software with state charts and using automatic code generation to convert them into C/C++ (for implementation) or Promela (for model checking)
- Tracking the north polar ice caps (water and CO2) on Mars
