Synergistic Activities:
Developed Emission Mössbauer Spectroscopy as a viable microscopic tool for the study of biophysical and materials systems. It is several orders of magnitude more sensitive than the conventional mode involving absorption. Our earlier work showed that molecules and other systems with large numbers of delocalized electrons can lose the super-excitation energy resulting from the neutralization of charge following the Auger event in the 57Co microprobe by a novel mechanism. We proposed that the collective excitation of loosely bound electrons due to neutralization is followed by plasmon de-excitation, and all the energy imparted to a single electron (this mechanism has been recently verified by two reports in Phys. Rev. Lett.). Consequently, the epicenter escapes radiation damage despite initial deposition of more than 50eV excitation energy
Developed several undergraduate and graduate physical chemistry courses with main emphasis on understanding basic underlying physical concepts rather than just memorization of equations.
