I am a researcher in computational materials science interested in the intersection of machine learning with traditional simulation techniques. My recent work has spanned computational materials discovery, machine learning applied to first principles simulation, and battery informatics.

As of August 2026, I work at NVIDIA as a Senior Strategic Alliance Manager. Previously, I was a Senior Research Scientist at Toyota Research Institute. You can view the papers that I’ve written on my Google Scholar.

I am passionate about serving the scientific and academic communities in my spare time. I currently serve on the external advisory board of the UC Merced Department of Mechanical Engineering and on the Program Advisory Board of the University of Rochester’s Department of Mechanical Engineering.

Prior to that, I was a DOE Computational Science Graduate Fellow, and a Barry Goldwater scholar. I obtained my Ph.D. in Physics with a secondary in computational science & engineering from Harvard University, where I worked under Prof. Boris Kozinsky, and a B.S. in Physics and a B.A. in Mathematics from the University of Rochester.

🧪 Research Directions

My research interests are accelerated atomistic simulation, agentic science, and materials informatics. I focus on building interpretable and scalable methods that connect first-principles simulation, experimental data, and AI-driven discovery.

1. Accelerated Atomistic Simulation

I am interested in ML models — including surrogate models, interatomic potentials, and property predictors — that accelerate traditional quantum simulations and uncover patterns in atomistic simulation.

Selected Works:

• 📄 Simultaneous Discovery of Reaction Coordinates and Committor Functions Using Equivariant Graph Neural Networks
  Sheriff, Freitas, Trewartha, Torrisi, AI for Materials @ NeurIPS Workshop 2024
• 📄 Benchmarking FLARE and NequIP with the TM23 Dataset
  Owen & Torrisi, npj Computational Materials (Co-first author)
• 📄 On-the-Fly Active Learning of Bayesian Force Fields
  Vandermause, Torrisi, et al., npj Computational Materials

2. Agentic Science

I am interested in AI agents and autonomous workflows that plan, execute, and interpret scientific campaigns — closing the loop between hypothesis generation, simulation, and experiment.

Selected Works:

• 📄 Toward Autonomous Materials Research: Recent Progress and Future Challenges
  Montoya et al., Applied Physics Reviews
• 📄 Agents for Sequential Learning Using Multiple-Fidelity Data
  Palizhati, Torrisi, et al., Scientific Reports

3. Materials Informatics

I work on data-centric models that turn spectroscopic, simulation, and device data into physical insight — from interpretable analysis of X-ray absorption and PDF spectra to statistical modeling of battery materials and devices.

Selected Works:

• 📄 Multimodal Analysis of PDF and X-ray Absorption Spectra
  Na Narong, Zachko, Torrisi & Billinge, npj Computational Materials (Corresponding Author with Simon Billinge)
• 📄 Tailored Ordering Enables High Capacity Cathode Materials
  With Northwestern University and Toyota Motor Corporation, Advanced Energy Materials
• 📄 Interpretable Analysis of Battery Formation
  With the D3BATT Collaboration (Sun, Bazant, Chueh, et al.), Joule
• 📄 Random Forest Models for Interpretable XANES Spectra
  Torrisi et al., npj Computational Materials

My interests

I am passionate about science communication, funk music, and mentorship. While I was a Ph.D. student at Harvard, I was a resident tutor at Cabot House for four very happy years.
