Overview
Dr. Jake Turner [he/him/his] is currently a NASA Hubble/Sagan Postdoctoral Fellow. Dr. Turner's research is focused on studying the magnetic fields, atmospheres, and orbital evolution of exoplanets. Dr. Turner was recently the lead author of a study that found the first possible detection of an exoplanet in the radio.
Jake received his bachelor degrees in physics and astronomy in 2011 from the University of Arizona. As a graduate student, Jake was awarded a National Science Foundation Graduate Research Fellowship and spent two years as a visiting student at CNRS in Orléans, France. Dr. Turner received his PhD in astronomy in 2018 from the University of Virginia. Since 2018, he has been a postdoctoral research associate at Cornell University and was awarded the NASA Hubble Fellowship in 2021. In addition to his research, Jake is very active in social activism, photography, outreach, and currently runs the social media of the Carl Sagan Institute.

Research Focus
Exoplanet magnetic fields: radio observations, spectropolarimetry, near-UV asymmetries
Dr. Turner is currently part of the Radio Exoplanets with LOFAR Team, the NenuFAR “Exoplanets and Stars” Key Science Program team, the Square Kilometre Array Cradle of Life Team, and the LuSEE (Lunar Surface Electromagnetics Experiment) Team. Also, he is on the exoplanet science committee for FARSIDE (Farside Array for Radio Science Investigations of the Dark ages and Exoplanets).
Exoplanet atmospheres: high-resolution, JWST, and ground-based low-resolution
Dr. Turner is the PI of the ExoGemS (Exoplanets with Gemini Spectroscopy survey) large survey on Gemini-N and part of the JWST Transiting Exoplanet ERS team and the NIRISS Exoplanets (NEAT) team.
