● production

Hard science, engineered into production.

I work where research-grade modeling meets operational software: translating open-ended climate questions into auditable systems, clear uncertainty, and products teams can use.

01.1 / CURRENT

Severe-storm intelligence at global scale

Lead MSCI’s blizzard, dust-storm, and sandstorm modeling program end to end — architecture, AI weather emulation, GPU ensembles, validation, and production delivery.

01.2 / PLATFORM

Petabyte-scale climate data pipelines

Architected containerized ETL on AWS Batch, serving Zarr, Parquet, and NetCDF data to downstream analytics and client-facing products.

01.3 / OPEN SCIENCE

Source attribution people can inspect

Built and open-sourced C-TRAIL, a Lagrangian trajectory framework adopted by external research groups to trace downstream outcomes to upstream sources.

GeospatialFortranAtmospheric science

From atmospheric research to enterprise climate risk.

My career connects physical understanding, statistical rigor, and engineering discipline — with increasing ownership of teams, platforms, and product outcomes.

2026 — NOW

Senior Data Engineer (Data Science)

MSCI · New York

Lead global severe-storm hazard modeling; build production ML, ensemble forecasting, extreme-value analysis, and AI-assisted diagnostic workflows across hundreds of millions of records.

2025 — 2026

Data Engineer / Research Scientist

First Street · New York

Designed global ML workflows, automated QA and anomaly detection, and petabyte-scale AWS pipelines for climate-risk analytics before First Street’s acquisition by MSCI.

2023 — 2025

Postdoctoral Research Associate

NOAA GFDL / Princeton University

Led a modeling workstream across four research groups and 8+ scientists; benchmarked predictive components, documented uncertainty, mentored researchers, and published high-dimensional climate analysis.

2018 — 2023

Graduate Researcher and Postdoctoral Fellow

University of Houston

Developed Bayesian data assimilation, particle transport, data-fusion, and deep-learning methods; earned a PhD in Atmospheric Science and open-sourced many tools including C-TRAIL.

A deep technical range, centered on delivery.

I move comfortably from model formulation to distributed compute, from validation design to executive communication — choosing the level of abstraction the problem needs.
