New physics written into the cosmos.
I connect fundamental model building to observable signatures using analytical theory, numerical simulations, and cosmological data.
Early Universe
Axions, isocurvature & primordial dynamics
A central theme of my work is understanding how new fields and nontrivial dynamics during inflation generate measurable primordial fluctuations. I study axionic blue isocurvature, rotating complex scalars, geometric suppression mechanisms, resonant and chaotic regimes, and explicit symmetry breaking.
Recent: geometric suppression of CMB isocurvature ↗Structure Formation
Warm, fuzzy & mixed dark matter
I investigate how nonstandard dark-matter scenarios alter structure formation, particularly at small scales. This includes warm and fuzzy dark matter, mixed dark-matter models, and the interplay between dark-matter free streaming and primordial isocurvature.
Recent: reviving sub-keV warm dark matter ↗Cosmological Inference
Large-scale structure & high-redshift galaxies
I use complementary probes across cosmic scale and time: galaxy clustering, EFTofLSS and bias expansions, DES harmonic-space analyses, and ultraviolet luminosity functions of high-redshift galaxies. The goal is to turn theoretically motivated signals into robust observational constraints.
Recent: JWST UVLF isocurvature constraints ↗AI for Science
Reasoning in theoretical physics
Through TPBench, I have helped evaluate advanced AI systems on theoretical-physics problems spanning undergraduate material through research-level reasoning, including work on test-time scaling methods.
