My name is Fei Dai (戴飞). I'm a Postdoctoral fellow in the Division of Geological and Planetary Sciences at Caltech. I obtained my PhD in physics from MIT under the supervision of Prof. Josh Winn .
The discovery and characterization of new, exciting planetary systems with Kepler and K2 and the newly inaugurated TESS mission is the focus of my research. Using both novel data analysis techniques and numerical simulations, I want to understand the composition, orbital architecture and atmospheric loss of planets which in turn tell us about their formation, evolution and habitability. In order to figure out how extreme can planet formation be at the hottest end, I study the planets with shortest possible orbital period (hours to days). These "hot Earths" present an opportunity to look at processes such as tides, photoevaporation, star-planet interaction that govern planet formation and evolution in general but may be too slow/weak to be observable for longer period planets.
