• Ph.D.: Syracuse University (synthesis and characterization of zeotype materials)
• Post Doc: National High Magnetic Field Laboratory (solid-state NMR of biological systems at 25T, design and construction of high frequency NMR probes and spectrometer)

Research in the area of experimental solid state phsyics and chemistry.
Areas of reseach include:

• zeolite-like materials for energy applications
• hybrid inorganic/organic systems
• biomolecular systems
• organic semiconductors

A major thrust in the group is the synthesis and characterization of novel materials, with desired functionality, through various chemical methods. Physical characterization methods ranging from x-ray crystallography to various spectroscopies to provide a structural understanding for the observed electronic properties measured. The overall aim is to correlate synthesis conditions to resulting electrical characteristics - ionic and electronic conductivities- from a fundamental as well as an applied perspective for materials discovery.
