Dr. Ue-Li Pen, Distinguished Research Fellow and Director of the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), was awarded 2022 Class of Fellows to the Royal Society of Canada (RSC). The news was announced by RSC on September 6, 2022. Director Pen’s area of research is theoretical astrophysics with recent focus on fast radio bursts and pulsars. His current projects include the non-linear dynamics of the cosmic neutrino background, 21cm intensity mapping, pulsar VLBI scintillometry, Canadian Hydrogen Intensity Mapping Experiment (CHIME), and Bustling Universe Radio Survey Telescope in Taiwan (BURSTT).

Pen is one of the earliest theoretical astrophysicists in Taiwan. He pioneered the rapid growing field of 21-cm cosmology and his work culminated in preeminent astronomical achievements of the CHIME. More recently, his innovative use of cosmic plasma as a giant telescope spawned the new field of scintillometry.

Pen obtained his Ph.D. from Princeton University. He has been a Professor at the Canadian Institute for Theoretical Astrophysics (CITA) at the University of Toronto since 1998 and has been a Distinguished Research Fellow and Director of the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) since September 2021.
