Double Neutron Stars Across Cosmic Time
Double Neutron Stars Across Cosmic Time
How do double neutron stars form across the history of the Universe?
The evolution of massive stars depends strongly on metallicity, making their evolution fundamentally different across cosmic time. This project investigates how metallicity-dependent stellar evolution influences double neutron star formation, and makes predictions for current and future gravitational wave observatories.
Paper: In-prep.
Can binary evolution constrain the delay times of double neutron stars?
The time between star formation and merger is essential for predicting their contribution towards r-process enrichment, gravitational wave events, and gamma-ray bursts. This work investigates how these delay times change across cosmic metallicities and reveals the critical role played by the evolution of the helium star–neutron star phase.
Paper: ApJ (2026)
How did the double neutron stars in our own backyard form?
The Milky Way provides a unique laboratory for testing theories of binary stellar evolution. By using detailed models from POSYDON, this work identifies a key bifurcation in the evolutionary pathway that naturally explains the observed orbital period split of the Galactic double neutron stars, and explores what it reveals about massive binary interactions.

Forming Gaia Neutron Stars
Forming Gaia Neutron Stars
How can a neutron star survive in a wide, eccentric orbit around a Sun-like star?
The recently discovered Gaia neutron star binaries challenge our understanding of binary evolution, requiring systems to potentially survive both mass transfer and supernova explosions while remaining widely separated. This project explores their evolutionary origins and investigates what these binaries can teach us about massive binary evolution and supernova physics (Image credit: Caltech/Kareem El-Badry).
Paper: In-prep.
How do we accurately detect and characterize merging black holes that have not fully circularized?
Most gravitational wave models assume nearly circular binaries, yet some mergers are expected to retain eccentricity. This work developed waveform models for eccentric binary black holes including higher-order spherical harmonic modes by comparing analytical post-Newtonian predictions and numerical relativity simulations.

POSYDON Code Development and Open Data
POSYDON Code Development and Open Data
As part of the core developers' team of POSYDON, I contribute to the computational infrastructure and development of the codebase. My work primarily centers on constructing extensive grids of detailed binary evolution models with MESA, which are used to study stellar interactions and the formation and evolution of compact object binaries across a wide range of astrophysical environments.
Many of the data products and binary evolution grids that I have developed are publicly available through Zenodo:
High-resolution grids of compact object - hydrogen star binary evolution models at solar metallicity, at onset of Roche-lobe overflow (CO-HMS_RLO) [Zenodo].
Grids of compact object - helium star binary evolution models with dedt_hepulse rerun at solar metallicity (CO-HeMS) [Zenodo].
High-resolution grids of compact object - hydrogen star binary evolution models at multiple metallicities, at onset of Roche-lobe overflow (CO-HMS_RLO) (in-prep).
MESA inlists for neutron star - helium star binary evolution models with Vink (2017) wind mass loss implementation [Zenodo].
Grids of helium star - hydrogen star binary evolution models at multiple metallicities (HeMS-HMS) (in-prep).
