The goal of my research in theoretical particle physics is to galvanize the search for new phenomena beyond the Standard Model as well as to illuminate the structure of the Standard Model itself. My work often combines first-principles calculations in quantum field theory with data analysis techniques from machine learning.

Machine learning has impacted many scientific fields, and particle physics is no exception. In my research, I aim to enhance the search for new phenomena at colliders by merging the performance of deep learning algorithms with the robustness of “deep thinking” approaches.

Collider Physics and QCD
High-energy particle collisions are dominated by QCD (quantum chromodynamics), which describes fundamental interactions among quarks and gluons. My research has yielded new ways to analyze collider physics data and new ways to compute the properties of QCD.

Beyond the Standard Model
The Standard Model has survived a half-century of precision tests, yets it leaves many unanswered questions, such as the nature of dark matter, the apparent weakness of gravity, and the symmetry structure of our Universe. In my research, I study hypothetical scenarios for physics beyond the Standard Model (BSM) and new experimental strategies to uncover evidence for new physics.
