Research

I am a multiwavelength observational astronomer interested in compact binary interactions and accretion physics. For my PhD I primarily study transitional millisecond pulsars with Prof. Jay Strader. I routinely observe with the 4.1-meter Southern Astrophysical Research (SOAR) Telescope located in Chile, and I have been the Principal Investigator of successful proposals awarded time by the Swift and XMM-Newton X-ray missions and the ground-based Gemini Observatory.

I have served as the primary research advisor to undergraduate students at MSU who worked on identifying new "spider" pulsar candidates and discovering new radio nebulae assoicated with ultraluminous X-ray sources.

Prior to my graduate studies, I studied the X-ray variability of sources in M33 to characterize the duty cycles of high-mass X-ray binaries; created a database of the Liverpool Telescope's spectroscopic nova observations to model their ejecta; and searched for state-changing X-ray binary candidates with optical light curves from the Zwicky Transient Facility.

First-Author Publications

  • Kyer, R., Roy, S., Strader, J., et al. 2025, ApJ, "Multiwavelength Evidence for Two New Candidate Transitional Millisecond Pulsars in the Subluminous Disk State: 4FGL J0639.1-8009 and 4FGL J1824.2+1231"

  • Outreach & Activities

    I organize two programs at MSU that support undergraduates in astronomy and aim to retain students from underrepresented backgrounds: the Stellar Mentorship Program, and Physics and Astronomy Research Experiences for Drew Scholars (PAREDS).

    Within the MSU Astro Group, I organize our weekly Astro Coffee journal club. I volunteer at the MSU campus observatory's public outreach nights, and I have presented photographic plate observations acquired there in the 1970's at Astronomy on Tap in Lansing. I am currently working to digitize the photographic plate collection to make it available to the community. Below is a scan of a plate targeting the Orion Nebula observed at the MSU campus observatory in 1971.

    Just for fun: Film photography

    One of my favorite hobbies is shooting film and working in a darkroom. I'm lucky enough to be in the same city as the last remaining community darkroom in the state of Michigan: Community Darkroom 517. Check out info about that space and some of my work below.
