I am a theoretical cosmologist working as a post-doc at the Centre for Particle Cosmology at the University of Pennsylvania. I earned my PhD from Johns Hopkins University under the advisement of Prof. Marc Kamionkowski in 2019.
My research focuses on building and testing models of dark energy and dark matter using various cosmological datasets. I am passionate about teaching and diversity in physics. Beyond physics, I love cake and scuba-diving.


My research investigates dark energy and dark matter through cosmological anomalies.
You can find my publications on INSPIRE or the arχiv.

Although the ΛCDM model of cosmology has been tremendously successful, particularly in describing the cosmic microwave background (CMB), as cosmological measurements become more precise, numerous tensions have emerged between the results of different datasets. These coupled with some unexpected results may indicate physics beyond the concordance model; a revision of how we describe the dark sector. I am a theorist who likes to think about what new physics might lie beyond ΛCDM.

I am interested in theories testable against observables. In particular, I constrain new physics with the cosmic microwave background radiation. I am also interested in cosmic rays and gamma rays, and what we might ascertain about dark matter and pulsars from these datasets. Numerous experiments will have new cosmological results in the near future, including but not limited to LSST, DES, WFIRST, SDSS, Fermi and CMB-S4 (not so near future) and I am interested in exploring what we might learn about dark matter and dark energy from these.

More specifically, I have worked on:

Resolving the Hubble tension with early dark energy

Pulsars as a source of the cosmic-ray positron excess

Decaying dark matter as a solution to both the Hubble and S8 tensions
