Thomas Dawson - Dawson is a Ph.D. student currently working on the holographic interpretation of a class of bottom-up models, as well as their possible realizations as compactifications of higher-dimensional theories. His interests also include braneworld constructions, holography, and broader questions in quantum gravity.
Hao Geng - Hao's research focuses on concretely understanding the emergence of spacetime geometry from quantum entanglement in quantum gravity.

Akshay Ghalsasi - Akshay's research lies at the intersection of particle physics, astrophysics and cosmology. He works on building models and exploring the phenomenological consequences of dark matter, dark energy, neutrino masses and baryogenesis. His current projects include (among others) explaining the anomalous growth of super massive black holes in the paradigm of dissipative dark matter, enhancement of the matter power spectrum at k ~10 Mpc^{-1} in axion kination, and exploring isocurvature of ultralight scalar dark matter coupled very weakly to SM fermions present in the primordial bath.

Jackie Lodman - Jackie's research is focused on the intersection of particle physics and cosmology. She is working on new methods of probing ultralight dark matter, RS models, grand unification, and Higgs criticality. Jackie is also interested in new ways of using precision measurements to test BSM scenarios at a muon collider.
Rashmish Mishra - Rashmish's current research focuses on early universe dynamics and the phenomenology of strongly coupled beyond-the-Standard Model (BSM) theories. He investigate these topics using extra-dimensional holographic duals, with the goal of identifying observable signatures at gravitational wave detectors and in inflationary observables. Such signals may arise, for example, from deconfinement–confinement phase transitions or from instabilities in hot phases of new sectors active in the early universe. During inflation, presence of such sectors can give rise to deviations in the scalar and tensor power spectrum, as well as lead to very interesting non-Gaussianities and cosmological collider signals. These phenomenological questions are closely linked to his formal interests in quantum field theory and quantum gravity, particularly towards the study of non-perturbative phenomena. Additionally, Rashmish is interested in applying machine learning methods to challenging problems in high energy physics.

Michael Nee - Michael is working on supersymmetry in extra dimensions, in particular on deriving 4d effective theories from 5d supersymmetric theories and the implications for anomaly mediation. He is also working on understanding the implications of theories with extra dimensions on inflation, looking for novel signatures that could be seen in the CMB or galaxy surveys. He has an interest in axion physics, and his work in this area has focused on how axion parameters are restricted in unified theories and heterotic string models.

Marcos Riojas - Marcos's research explores quantum aspects of gravity in controlled settings such as the AdS/CFT correspondence, where entanglement islands have driven recent progress on the black hole information paradox. He is also interested in the phenomenology of the Randall-Sundrum model, which is closely related to black-hole physics, undergoes similar phase transitions, and can support entanglement islands on the brane in holographic settings. He is especially interested in settings with more than two dimensions, where we lack a detailed understanding of where Hawking radiation is emitted and how information is transferred from a black hole to its radiation.
