Jongyoon Han Selected as van Tassel Assistant Professor of Biomedical Engineering: Professor Han received the B.S. and M.S. degrees from the Department of Physics, Seoul National University, Seoul, Korea, in, respectively, 1992 and 1994. In 2001, he received the Ph.D. from the School of Applied and Engineering Physics, Cornell University. Before joining MIT in July 2002, he was a research scientist at Sandia National Laboratories, Livermore, CA. His research focuses on understanding biological systems which critically depend on the tools available to analyze biomolecules and sub-cellular biological components. This is done by focusing on developing new tools and technologies for biomolecule separation and analysis using advanced microfluidics and nanofluidics.

Matt Lang Chosen as Keck Assistant Professor of Bioengineering: Professor Lang received the B.S. from the University of Rochester (1992) and his Ph.D. from the University of Chicago (1997). He came to MIT after holding positions as a Postdoctoral Fellow at the University of California, Berkeley (1998), Princeton University (1998-99), and Stanford University (1999-2002). His general research interests lie in elucidating the inner-workings of proteins, enzymes and biological motors, using instrumentation that combines optical tweezers, single molecule fluorescence and pulsed spectroscopy. This research is directed towards developing a molecular level description of the motions associated with structural, mechanical, dynamic and energetic changes of these biological systems. Through these emerging technologies, significant advances in the ability to measure receptor/ligand interactions, the inner-workings of biological motors and interactions between multi-unit protein complexes will be achieved, thus providing a deeper understanding of these biological systems.
