Research
Sonar Data Analysis
I co-lead the UW Echospace group, where I collaborate with oceanographers to combine data science, acoustics, mathematics, and software engineering to advance ocean acoustics research. Below are some topics of interest:
- matrix and tensor decomposition of long-term echosounder time series (OOI Science Highlight )
- supervised learning of fish aggregations in acoustic surveys
- tools facilitating echosounder data workflows (https://github.com/OSOceanAcoustics)
Check out our group https://uw-echospace.github.io/ to learn more about our work.
Passive Acoustic Monitoring
I collaborate with the Orcasound organization on projects engaging the public in listening to underwater sounds through combining the efforts of AI and humans. Together we have participated in the Google Summer of Code program and have worked with many wonderful students from around the world to develop open source software and data sets. Read more on our experience here. Below are more details on some of the projects:
- OrcaAL Tool: Active Listening and Learning of Orca Sounds
- Github Actions Workflows for Scheduled Algorithm Deployment
- Sounds Similar for Me: Using Open Embeddings to Improve Sampling on OrcaAL Tool
- Streaming External Hydrophones to Orcasound Website
- Streamlining OrcaAL Tool
- Bioacoustic Source Separation
I also work with masters students in the UW Master of Science in Data Science Program (as part of their capstones) on
Data Science for Social Good Projects
I have been involved in the development and implementation of the Data Science for Social Good summer program. I have been a data science lead for projects with diverse stakeholders and I have had the wonderful opportunity to mentor teams of talented students:
- Seattleās $15 Minimum Wage Ordinance, with West Coast Poverty Center (2021)
- Natural Language Processing for Peer Support in Online Mental Health Communities, with CSE and Psychiatry and Behavioral Sciences (2019)
- Automatic Damage Annotation on Post-Hurricane Satellite Imagery, with Disaster Data Science Lab, UW (2018)
- Can traffic sensor data detect vehicle cruising?, with City of Seattle Department of Transportation (2017)
- Mining Online Data for Early Identification of Unsafe Food Products, with Institute of Health Metrics and Evaluation (2016)
- Rerouting Solutions and Expensive Ride Analysis for King County Paratransit, with King County Metro and Taskar Center for Accessible Technology (2015)
Data Science Incubator Projects
Through the Data Science Incubator program I have supported many researchers in their dive into using data-intensive methods to extract information from complex and messy datasets and many of those projects have turned into fruitful long-term collaborations.
