Postdoctoral Research Associate
005 Peyton

Dr. Tansu Daylan is a Catalyst Fellow in the Department of Astrophysical Sciences at Princeton University. His research program covers aspects of exoplanets, dark matter, and astrostatistics. His work on exoplanets involves the discovery, characterization, and demographics of planets beyond our Solar System, with the goal of improving our understanding of planet formation, evolution, and migration. In his cosmology research, he focuses on the astrophysical signatures of dark matter and gravitational lensing as a probe of the small-scale structure of dark matter at sub-galactic scales. He develops numerical methods such as neural networks, autoencoders, and transdimensional samplers to enable fast and accurate solutions to relevant data analysis and inference problems in astrophysics.

In Fall 2023, he will join the faculty at Washington University in St. Louis as an assistant professor of physics. Dr. Tansu Daylan holds a double major in electrical and electronics engineering and physics from METU, Turkey, and as an undergraduate worked on cosmic ray detection as part of the AMS-02 collaboration at CERN. He received his PhD in physics from Harvard University in 2018, where he characterized the gamma-ray emission from the inner Milky Way to show its consistency with the products expected from the self-annilihation of weakly interacting massive particles (WIMPs). Following his PhD, he became a Kavli Fellow at MIT Kavli Institute and has since led various projects in the TESS Mission including the TESS Objects of Interest process, the spectroscopic follow-up of detected exoplanet candidates, and characterization of exo-atmospheres. He became a TESS Postdoctoral Associate in 2021. His work on the TESS data has enabled the discovery of over five thousand planet candidates and some of the prime discoveries of TESS such as the TOI-1233 multiplanetary system with an exceptionally bright host star. More recently, he was awarded the Catalyst Fellowship by LSSTC and the John Templeton Foundation to investigate the expected yield of the Legacy Survey of Space and Time (LSST) on transiting exoplanets and stellar binaries with compact companions.
