Research Interests

My research focuses on using multi-messenger astronomy to study the Universe, coming at the same problem from multiple directions to gain a more complete picture. In particular, I study the coalescence of binary neutron stars with both gravitational waves and electromagnetic data, predominantly using wide field-of-view optical telescopes such as the Zwicky Transient Facility (ZTF) to identify these counterparts. I also use these telescopes to search for future sources from the Laser Interferometer Space Antenna (LISA), a space-based gravitational wave detector that will study white dwarf binaries in our galaxy as well as binary black hole mergers.
