Pisin Chen is currently the Distinguished Chair Professor of the Department of Physics, National Taiwan University (NTU). He is the founding Director and the Chee-Chun Leung Distinguished Chair Professor of Cosmology of the NTU Leung Center for Cosmology and Particle Astrophysics (LeCosPA) since 2007. He has made seminal contributions in plasma physics, particle beam physics, cosmology, particle astrophysics, classical and quantum black hole physics. He was elected as Fellow of American Physical Society in 1994. In 2018, he was awarded with the Blaise Pascal Chair by the government of Ile de France for his conception of the laser-induced flying plasma mirror as an analog black hole to investigate Hawking radiation and the information loss paradox. He is a recipient of the 2023 European Physical Society Hannes Alfven Prize for his invention of the plasma wakefield accelerator (PWFA). He led the experiment at SLAC that successfully demonstrated the plasma lens principle in 2000 as he predicted in 1987. He is a two-time recipient (1994, 2002) of the Essays on Gravity competition awards organized by Gravity Research Foundation. He initiated and led the international ARA Observatory at the South Pole in 2009 to search for ultra-high energy cosmic neutrinos. His current research focuses on theoretical and experimental investigations of the black hole information loss paradox.
