Dr. Haidan Wen is a physicist in the X-ray Science Division at Argonne National Laboratory. Prior to his current position, he was a research associate at SLAC National Laboratory and Stanford University. He received his Ph.D. in physics from the University of Michigan, Ann Arbor, in 2006 and B.S. from the University of Science and Technology of China in 2001.

Dr. Wen’s research focuses on investigating ultrafast dynamics of multiple degrees of freedom such as lattice, charge, and magnetic orders in quantum materials, by using a wide range of electromagnetic radiation including THz, optical, and X-ray pulses. He is interested in the phenomena that occur on nanometer to micrometer length scales where the energy conversion and transport are influenced by novel boundary conditions, collective dynamics, and mesoscale effects. He is developing advanced spatiotemporally resolved characterization techniques by integrating various x-ray microscopy and optical microscopy to tackle challenges of measuring and understanding nanoscale energy transport and conversion in the dynamical processes of phase transition, nanoscale thermal transport, nanoscale structure-property correlation.
