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 have also taught classes
in Computer Science at Cal State L.A. and Oregon State University.
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

- The video for my controversial ICML 2012 talk is no longer available (lost in a server crash).
However, you can read the original paper:
Machine Learning that Matters (pdf, 6 pages, 234K) and
see the slides from a subsequent invited AAAI talk:
Challenges for Machine Learning Impact on the Real World (1.6M).

Enabling Onboard Detection of Events of Scientific Interest
for the Europa Clipper Spacecraft.

- We make a case for the utility of onboard
analysis of data collected by Europa Clipper (future mission
to Europa) to enable prioritization of data for downlink.
We describe three onboard detection algorithms to address the
science goals detecting thermal anomalies (hot spots),
compositional anomalies, and active plumes. We also report
lessons learned from developing and evaluating these methods
in the context of an onboard computing environment and mission

- Automated Classification to Improve the Efficiency of Weeding Library Collections.
Kiri L. Wagstaff and Geoffrey Z. Liu.
Journal of Academic Librarianship, 44(2), p. 238-247, 2018.
- We evaluated several machine learning classifiers in terms of their ability to predict which books are most likely to be weeded from a collection. We applied this method to a collection of more than 80,000 items from an academic library and found statistically significant agreement (p = 0.001) between classifier and librarian decisions.
Marginalia in the digital age: Are digital reading devices meeting the needs of today's readers?
Melanie Ramdarshan Bold and Kiri L. Wagstaff.
Library & Information Science Research, 39(1), 16-22, 2017.
- We surveyed readers to find out about their attitudes toward marginalia, and whether and how often they indulged in it themselves. We also investigated whether marginalia translates into electronic books and which features are most desired by users of e-readers.
