		Seogjoo (Suggy) Jang Nanotechnology & Materials Science Remsen, Room 119C Phone: 718-997-4110 seogjoo.jang@qc.cuny.edu My research focuses on theoretical understanding of energy and charge flow dynamics in various condensed phase systems ranging from liquids to biological systems. A particular attention is paid to important quantum effects such as quantum coherence and tunneling. The research integrates three major components of theoretical chemistry - developments of new theories, large scale computation, and modeling of complex spectroscopic data. Our group has expertise in path integral simulation of condensed phase quantum systems, energy and charge transfer theories, quantum master equation theories, and modeling of photosynthetic light harvesting complexes. New efforts are being put forth for the modeling and computation of conjugated polymers, theories of nanoscale conductance, and Monte Carlo simulation of exciton migration in plastic solar energy devices. We have on going collaborations with photo and radiation chemistry group at Brookhaven National Laboratory and evolving collaborations with leading spectroscopy groups in the US. The laboratory is equipped with a Beowulf linux cluster of 17 nodes, each with 4GB memory dual Opteron 250.

We are also interested in discovering and developing new analytical approaches. In addition, we have related interests in computational chemistry (e.g. quasi-classical direct dynamics trajectory simulations) and nano-materials.

		Uri Samuni Biophysics, Biochemistry, Physical Chemistry, Bio-nanotechnology, Biophotonics Remsen, Room 26A Phone: 718-997-4223 Uri.Samuni@qc.cuny.edu Prof. Uri Samuni has a doctorate in Physical Chemistry from the Hebrew University of Jerusalem, Israel, and postdoctoral training at the Keck Biomolecular Laser Research Center, Albert Einstein College of Medicine. Our research is interdisciplinary in nature involving physical chemistry, biophysics, photonics and nanophotonics. The main objective of our research is combining spectroscopy, specifically, resonance Raman and surface enhanced Raman spectroscopy (SERS), sol-gel encapsulation of proteins and nanoparticles. In sol-gel encapsulation, proteins are embedded in the inert and optically transparent sol-gel matrix and yet remain functionally active. This constitutes a unique platform for the study of protein conformational dynamics and the characterization of non-equilibrium conformations as they relate to protein function. Moreover, depending on the preparative conditions, this novel photonic material lends itself to a large range of applications such as biosensors and sol-gel based nanoparticles and their biomedical applications.
