Professor Gundogdu received his PhD in 2004 from the University of Iowa. Then he continued his postdoctoral studies at the University of Iowa between 2004-06 and at the Massachusetts Institute of Technology between 2006-08. He recently joined the physics faculty at North Carolina State University.
During his PhD work, he used ultrafast spectroscopic techniques to study electron and hole spin dynamics in quantum dots and narrow band gap semiconductor heterostructures with the motivation of developing spin based electronic devices. In his postdoctoral studies, he developed novel spatio-temporal pulse shaping methods for IR and optical 2D Fourier transform spectroscopy, the optical analogue of multi-dimensional NMR experiments. He performed these experiments to study electron dynamics in condensed matter systems and vibrational dynamics in biomolecules and hydrogen bonding complexes.
Prof. Gundogdu’s research at NC State involves developing novel ultrafast spectroscopic methods to address problems in condensed matter physics and nanoscience. His program especially focuses on the investigation and characterization of coherent and incoherent exciton dynamics that play a critical role in determining the energy conversion efficiency in photovoltaic devices. His ultimate goal is to provide clear understanding of photon absorption, exciton transport, and charge separation dynamics in novel nanostructures to help engineering high efficiency solar energy conversion devices.
