Atlas: Navigating NASA’s Knowledge Universe with AI-Powered Natural Language Queries
Atlas allows users to ask natural language questions and receive answers grounded in factual information from source documents. It can address a wide range of queries, from specific technical details like safe distances for rocket launches from lightning to broader topics such as crew health requirements for long-duration space missions, corrosion protection in low Earth orbit, and NASA's agreements with various entities.
Moving Beyond Local LLMs
NASA Summer of AI talk describing the shapes and sizes of Large Language Models (LLMs), an overview of important parameters, and a discussion of quantization as it applies to day-to-day scenarios.
Cloud-Native Geospatial Considerations for State Governments
A subject matter expert overview of cloud geospatial workloads and the considerations around how data is structured and accessed by medium organizations like state governments.
2019
Improving Information and Communications in a Disaster Scenario with AWS Snowball Edge
Prototype disaster‑response pipeline for field data management leveraging AWS Snowball Edge and a serverless, cloud‑based architecture.
The Pangeo Platform: a Community‑Driven Open‑Source Big‑Data Environment
Overview of the Pangeo ecosystem and its interactive, reproducible workflows for petabyte‑scale Earth‑science datasets.
Acquiring, Processing & Analyzing Open Broadcast Science Data at Scale with AWS Ground Station
Demonstrated an end‑to‑end, low‑latency cloud pipeline—from satellite scheduling through Level‑0 processing—entirely within AWS.
Community Tools for Analysis of NASA Earth Observation System Data in the Cloud
Status update on ACCESS project expanding Pangeo access to EOSDIS holdings; highlighted STAC, Intake, and Kubernetes workflows.
Security and Compliance in the Government Cloud
Mapped NIST 800‑53 controls to modern cloud services and proposed adaptive security models for rapidly evolving infrastructures.
An Introduction to Pangeo
Hands‑on primer covering Xarray, Dask, and Jupyter within the Pangeo stack, tailored to remote‑sensing data users.
Cloud‑Native Archives of Convenience for Remote‑Sensing Workloads
Argued for on‑demand, context‑specific data transformations (COGs, Zarr) instead of monolithic “gold” formats.
Building CubeSat Data Pipelines with Open‑Source Software at Element 84
Surveyed open‑source geospatial tooling for small‑satellite operators and introduced SatCat proof‑of‑concept pipeline.
2018
What Interdisciplinary Research, Heterogeneous Data & Netflix Have in Common
Presented concept of “ephemeral archives of convenience” that tailor remote‑sensing data formats to individual analysis needs.
Observing Earth: A Brief Introduction to Earth Data
Introductory talk for data‑science professionals outlining NASA Earth‑observation assets and public‑access resources.
2017
Cloud Surprises Discovered in Moving NASA EOSDIS Applications into Amazon Web Services
Lessons learned and unexpected challenges encountered during early cloud migration efforts for NASA Earth‑science web apps.
