Professional Summary
Data scientist and software engineer completing a PhD in seismology (defending June 2026), specializing in building analysis pipelines for large scientific datasets (~775,000 events and ~12 million records). Experience spans the full stack of scientific computing: ingesting and cleaning messy real-world data, designing efficient numerical algorithms, and building analysis and visualization workflows. Comfortable working across Python (NumPy, pandas, SciPy, ObsPy, GeoPandas), high-performance computing environments, Linux, and real-time data streams. Author of peer-reviewed publications and open-source scientific tools.
Experience
-
2021 - San Diego, California
Graduate Student Researcher
Scripps Institution of Oceanography, UC San Diego
- Developed methods for characterizing earthquake source properties, applied to catalogs of ~775,000 events and ~12 million seismograms
- Introduced the normalized frequency index (nFI), a metric distinguishing spatial variations in earthquake source physics; released as an open-source end-to-end Python pipeline (py-nfi)
- Contributed to the SCEC/USGS Community Stress Drop Validation Study, a multi-institution comparison of stress-drop estimation methods applied to the 2019 Ridgecrest sequence
- Participated in the SCEC Array of Arrays field deployment (2024), assisting in the installation of ~400 temporary geophones across five Southern California sites
- 4 peer-reviewed publications and 10 conference presentations (AGU, SCEC, SSA, EGU)
-
2018 - 2019 Santa Barbara, California
Undergraduate Research Assistant
University of California, Santa Barbara
- Worked with Prof. Toshiro Tanimoto on cross-correlation of seismic noise in the Los Angeles basin
- Worked with Prof. Robin Matoza on elastic wave propagation simulation
- Presented results as a poster at the SCEC Annual Meeting (2018)
-
2019 - 2020 Campbell, California
Geotechnical Associate
C2Earth, Inc.
- Built an internal project-tracking web application (custom HTML/JS frontend, MySQL backend) deployed on the company’s local network; replaced a single overloaded spreadsheet of thousands of projects with searchable, editable records adopted by the firm
- Supported residential and commercial construction projects through field and laboratory work: conducted soil compaction and soil analysis tests, and generated settlement contour maps from hydrostatic level surveys of existing buildings
