DATA-DRIVEN CPS LAB, Research Assistant | Golden, CO | Aug 2023 – Present

Role: Research Assistant

  • Working under Dr. Gabe Fierro, focusing on SHACL validation and inference in RDF graphs.
  • Developing novel algebra for SHACL validation to streamline and optimize data manipulation.

Thesis Abstract: Flow-SHACL (click to expand)

Flow-SHACL addresses the limitations of existing SHACL validators. SHACL (Shapes Constraint Language) is a W3C standard used to validate RDF (Resource Description Framework) data against a set of conditions or "shapes."

Traditional SHACL validators face performance challenges, especially as knowledge graphs scale to millions or billions of nodes. Flow-SHACL tackles this issue with a dataflow-based approach, constructing an optimized data structure that maps SHACL operations as a dataflow graph.

This novel approach not only improves performance but also enables inference capabilities, providing deeper insights into the validation process and offering a more scalable solution for handling large knowledge graphs.

SLOAN PROJECT, Frontend Developer | Leadville, CO | May 2024 – Present

Developed a community energy dashboard for residents to monitor and compare energy usage with peers.

Features I Am Proud Of:

  • Real-time comparison: Users can track their energy usage against neighbors.
  • Accessibility: Dark/light mode and language toggle for better UX.
  • Feedback system: Built a system where residents (non-admins) can submit feedback, and admins can view and manage it.
  • Admin control: Admins can refresh the webpage for non-admin users and add announcements.
  • Real-time notifications (In Progress): Building an Amazon SNS real-time texting system for announcements and updates.

The frontend system webpage is confidential.
