Gustavo Marques Tavares

Gustavo Marques Tavares is an Assistant Professor in the Department of Physics & Astronomy at the University of Utah, specializing in Theoretical Particle Physics. His research bridges dark matter phenomenology, cosmological tensions, and experimental signatures of beyond-Standard-Model particles.

• PhD in Physics from Boston University (2015)
• Postdoctoral positions at Stanford University and University of Maryland

His research focuses on:

• Interacting dark matter and dark radiation models (e.g., SPartAcous)
• Axion and dark photon phenomenology (cosmic strings, supernova signals)
• Probes of dark sectors via colliders, gravitational waves, and multimessenger astronomy
• CMB spectral distortions and gravitational wave cosmology

The 15 most recent publications highlight expertise in dark matter detection, axion cosmology, and cosmological model fitting to address the Hubble and S8 tensions. Notably, his work on vector portals at lepton colliders (2025) demonstrates 1–2 orders of magnitude sensitivity improvement for dark photon models.

Scientific awards include:

• National Science Foundation grant (2024–2027) for dark sector probes

He teaches Advanced Electromagnetism and mentors Master’s research projects, emphasizing theoretical and experimental connections in particle cosmology.
