Research and/or Creative Works
The Liptak group aims to advance fundamental understanding of molecular electronic structure in complex chemical systems where this knowledge can transform the development of new antibiotics and clean energy technologies. In order to achieve these goals, we have developed diverse biochemical (recombinant protein expression, purification, and air-sensitive sample handling), spectroscopic (fluorescence, magnetic circular dichroism, and nuclear magnetic resonance), as well as computational (density functional theory, time-dependent density functional theory, and multi-reference perturbation theory) expertise.
Researchers in the Liptak group learn a variety of biochemical, spectroscopic, and computational skills in addition to management of a research project from the first experiments to journal publication. As a result, graduate student alumni have secured jobs in both academia and industry. The majority of undergraduate alumni have moved on to graduate programs in chemistry.
