معرفی
Sang-Kil Son is a Senior Scientist at the Center for Free-Electron Laser Science (CFEL), Deutsches Elektronen-Synchrotron (DESY), Germany, where he has been working since January 2014. He previously served as a Post-Doctoral Fellow at CFEL from 2010 to 2013, advised by Prof. Robin Santra. His academic background includes a Ph.D. in Physical Chemistry from the University of Kansas (2009), an M.S. from KAIST, Korea, and a B.S. in Chemistry from KAIST.
- Ph.D. in Physical Chemistry, University of Kansas, United States (2003–2009)
- M.S. in Physical Chemistry, KAIST, Korea (1997–1999)
- B.S. in Chemistry, KAIST, Korea (1993–1997)
Dr. Son's research focuses on theoretical atomic, molecular, and optical physics, particularly in extreme conditions induced by X-ray free-electron lasers (XFELs). His work spans strong-field physics from optical to x-ray regimes, electronic structure under intense radiation, and the development of computational methods such as XATOM, XMOLECULE, and TDVFD. He is deeply involved in simulating XFEL-matter interactions, including ionization dynamics, radiation damage, and ultrafast electron responses.
His publication record includes high-impact articles in journals like Nature, Nature Communications, and Physical Review Letters, with a consistent focus on x-ray science, multiphoton processes, and computational modeling. His recent work emphasizes relativistic effects, ionization potential lowering in plasmas, and the use of radiation damage for structural determination in femtosecond crystallography.
- Multielectron effects in strong-field ionization
- XFEL-induced dynamics in matter
- Quantum mechanical modeling of dense plasmas
- Development of simulation toolkits (XATOM, XMDYN)
- Theoretical support for ultrafast imaging
Dr. Son actively supervises Ph.D. students, postdoctoral researchers, and summer students at DESY, often in collaboration with Prof. Robin Santra. He has organized major scientific events such as the Ultrafast X-ray Summer School (UXSS) and regularly lectures on x-ray interaction with matter for DESY summer students. He also co-organizes the CFEL Theory Seminar series.
His research skills include advanced scientific programming (Fortran, C++, Python), code development for quantum dynamics, and the use of computational chemistry packages like Gaussian, GAMESS, and Octopus. He maintains an active presence in the international scientific community through invited talks and conference presentations.
