Chih-Ting Hsu

Chih-Ting Hsu is currently a postdoctral felllow at NCAR, and worked as a research associate with Prof. Tomoko Matsuo at CU Boulder in 2018-2019. She graduated from the Institute of Space Science, the National Central University, Taiwan. She visited Boulder while she was a graduate student and fell in love with this place, so she came back after receiving her PhD degree. She specializes in ionospheric radio occultation data assimilation and ionospheric weather prediction.
