معرفی
Dr. Ian J. M. Crossfield is an Associate Professor of Physics and Astronomy at the University of Kansas, where he leads the KU ExoLab research group dedicated to the discovery and characterization of nearby planetary systems. His research spans exoplanet formation, composition, detection, and characterization, with a focus on developing instrumentation to advance these pursuits.
Dr. Crossfield's research interests center on exoplanetary science, particularly the atmospheric composition and physical properties of exoplanets. His recent work includes mapping sulfur dioxide (SO2) in gas giant exoplanets using photochemical models, leading the OrCAS survey to measure masses of sub-Neptune exoplanets, and studying exoplanet atmospheres using both ground-based and space-based observations. His expertise spans photometry and high-resolution spectroscopy across multiple observatories.
His recent publications reveal a strong focus on exoplanet atmospheric characterization, with particular attention to transmission spectroscopy, thermal emission measurements, and photochemical modeling. His work often involves multi-wavelength observations and combines theoretical modeling with observational data from facilities like JWST, Spitzer, and ground-based telescopes.
- Chair of NASA Exoplanet Program Analysis Group (ExoPAG) Executive Committee (2025)
Dr. Crossfield has successfully mentored numerous students, including postdocs, PhD candidates, and undergraduates, several of whom have received prestigious awards like the NSF GRFP. His research group collaborates with institutions worldwide and utilizes advanced instrumentation for exoplanet detection and characterization. The KU ExoLab is actively involved in several major observational campaigns, including the OrCAS survey which involves 10 institutions using Keck/KPF and WIYN/NEID spectrographs.
