Multimodal machine learning to support more reasonable operation of fusion-grade plasmasWorking toward more realistic operations and control strategies for next-step fusion energy devices like ITER. Develop accurate yet robust dynamical models for fusion plasmas via multimodal learning (combining information from first-principles simulations with experimental data). Test and deploy AI-powered model-predictive + reinforcement-learning algorithms on national fusion device ($100 mil/year device). Collaborate with machine-learning researchers to bring latest AI tools to fusion (e.g. developing Discord chatbot to help operators parse through knowledge of logbooks from two decades of experimental operation). Personal strength in tethering to reality at all times, verifying/validating first-principles simulators alongside neural nets; and testing simple "tried-and-true" control algorithms alongside more advanced schemes.

Brought in ~$100,000 by automating vendor claimbacks / other integration tasks + designing/implementing pricing strategy. Developed portable and user-friendly interface for analyzing sales data.

Formed and led 15-student team to deploy NJ's first college-accredited prison computer science course. Also taught pre-algebra through calculus, and general computer literacy (including general business skills like budgeting and presentations); and tutored formerly incarcerated students enrolling in 4 year degrees. Recruited, trained, and organized new STEM teachers as a "Graduate Fellow"; and filled in as administrator for 2 weeks during program executives' leave of absence.

Helped set up new woodshop and makerspace for the Princeton community. Taught workshops and advised 50+ undergrads, grad students, postdocs, and staff members in completing research and hobby projects with an emphasis on safety and skills training.

Tutored local high school students in chemistry, statistics, calculus, physics, Python programming; and Princeton University undergrads in multivariable calculus, linear algebra, physics, organic chemistry, and statistics / R programming.Focused on helping students teach themselves.

Lab TA for computer science department's intro classes: guided students to correct their own mistakes + learn theory in Java, C, and assembly language projects

Oxford, Oxfordshire, Gb

Worked with Dr. Felix Parra and Jakob Svensson building Java module for estimating the probability distribution of the signal from a diagnostic (reflectometer) on state-of-the-art experimental fusion reactor JET. Integrated module into popular “MINERVA” Bayesian framework for holistic plasma diagnostics.

Ipswich, Ma, Us

Taught conservation/career workshops, organized litter pickups with local junior Canadian rangers, studied piping plover populations, analyzed marine debris and talked with local fisherman to strategize mitigation techniques (primarily placing and managing trash cans at local ports).
