About me

Since Fall of 2017 I have been a PhD student in Observational Cosmology at Stockholm University under the supervision of Hiranya Peiris and Jens Jasche. Prior to this, I completed my Master of Science degree in Astronomy also from Stockholm University in June 2017 with the thesis, "Linear Structure Formation of Ghost-Free Massive Bigravity". My undergraduate was spent in the United States where I completed three separate Bachelor of Science degrees in Aerospace Engineering, Mathematics, and Physics in May 2015. This was at Iowa State University where I was a student from Fall 2009. I grew up in the historical German colony of Amana in the beautiful Iowa river valley of Eastern Iowa.

I am part of the Large Synoptic Survey Telescope Dark Energy Science Collaboration (LSST DESC) and the Oskar Klein Centre for Cosmoparticle Physics. I am interested in observational probes of cosmology, such as compact binary mergers which emit in both electromagnetic and gravitational waves. Additionally, I have interest in researching high performance computing, computational methods for physics, and the cosmology of modified gravity theories. I am currently researching kilonovae, the optical counterpart to a neutron star-neutron star or neutron star-blackhole merger event. I am investigating their use as standard sirens and our ability to detect them with next-generation telescopes like the LSST

Please feel free to reach out and contact me, I am eager to discuss any of my research interests or cosmology in general!
