Professional Experience

Senior Nuclear Safety Analyst

Idaho National Laboratory

My current work focuses on probabilistic risk analysis, source term analysis, nuclear safety analysis, and equipment reliability. To date, my major contributions include leading a safety analysis and safety basis update for gas cooled nuclear fuel systems, working on the design team for a first-of-a-kind molten salt experiment, and development of a reliability model for the Advanced Test Reactor (ATR) bypass demineralizer system (a mission-critical system).

Senior Experiment Engineer & Experiment Safety Analyst

February 2023—July 2024

Idaho National Laboratory

As an senior experiment engineer and experiment safety analyst at the ATR, I was principle investigator on a project that evaluated failure of molten salt irradiation experiments in the ATR. This project paved the way for first-of-a-kind molten salt experiments that are now in design and will be irradiated in FY-27. In addition to this project, I developed a funding proposal to expand ATR’s Test Train Assembly Facility, which has now been included as a line item on the Department of Energy’s upcoming FY-27 budget request.

Experiment Engineer & Experiment Safety Analyst

November 2018—February 2023

Idaho National Laboratory

As an experiment engineer at the ATR, I participated in a wide variety of projects, operations, and experiments. My primary area of focus was safety analyses of novel irradiation experiments. I completed many detailed experiment safety analyses, authored ATR’s experiment irradiation and safety standard, overhauled the shipping process for irradiation experiment samples, and completed a mission critical project evaluating the effects of irradiated plastic when in contact with uranium-aluminide fuel.

Content Coordinator

March 2020—August 2020

Metaculus

Metaculus is a prediction solicitation and aggregation engine that has gamified probabilistic forecasting. As a content coordinator for Metaculus, I created a collaboration with researchers at the University of Massachusetts to forecast the path of the COVID-19 pandemic and inform the CDC. This project helped inform the CDC for decision making in the early pandemic. Additionally, I worked on product management and development. I wrote product specifications and analyzed customer behavior using Google Analytics. I also authored and developed quantifiable and resolvable forecasting questions.

National Nuclear Security Administration Graduate Fellow

June 2018—November 2018

Pacific Northwest National Laboratory

As an NNSA Graduate Fellow I served as Assistant Federal Project Director and risk subject matter expert on the NNSA Complex project at Kirtland Air Force Base. This involved a high degree of project planning and management, budgeting, and risk assessment. As part of this role I wrote a Monte Carlo risk simulator that made use of basic forecasting techniques to extremize team predictions. In addition, I attended the Defense Nuclear Weapons School and achieved Basic Nuclear Weapons and Nuclear Incident Response certifications.
