Prof. Jeff FitzgeraldOverview:
Synthesis and understanding of nonlinear optical materials.
Continuing projects: Tetraazaporphyrin / phthalocyanine hybrids for optical limiting. - Optical limiters are materials which transmit ambient light but are opaque to laser light.- Some Pb phthalocyanine complexes show good limiting but the analogous tetraazaporphyrin complexes are disappointing.

- Alex Kriegel, ‘12, found a way to make and separate four hybrids of phthalocyanine and tetraazaporphyrins.

Bz3TAP cis-Bz2TAP trans-Bz2TAP BzTAP- I would like to study the optical limiting behavior of Alex’s hybrids in order to understand the structure required for effective optical limiting.
Assoc. Prof. Shirley LinOverview:My background is in organometallic and supramolecular chemistry
with a focus on polymers.My research interests are:A) developing new catalytic transformations (with Prof MacArthur
and CDR Brown, USNA)B) synthesis of new functional materialsC) chemical education (with Prof. Hartman, USNA)
Project : tandem catalytic synthetic methodologies (fulfills biochemistry concentration)

Prof. Joe Urban
Overview:Computational chemistry/molecular modeling of organic and bioorganic compounds
Projects: Molecular Modeling Studies of Model Peptide MimicsComputational chemistry techniques are being used to investigate the conformational properties of modified peptide compounds. The work involves using molecular modeling software (ex: Spartan) on local computers as well as remote DoD supercomputers.

Peptide Bond Modifications Amino Acid Modifications

• The mimics we study come from the modification of either the peptide bond that links amino acids in a natural peptide, or the amino acids themselves.
• We use molecular modeling to investigate how these modifications impact the structure and properties of the mimics in comparison to their natural peptide counterparts.
Professor Craig WhitakerOverview:
My research areas focus on materials and polymer chemistry.
Project:Smart hydrogels incorporating chemical agent markers and dye sensor molecules are being synthesized and characterized. The novel polymeric materials will use a chemical reaction to detect and destroy organophosphorus nerve agents (Sarin gas). The stimuli-responsive hydrogels will act as sensors when immersed in water supplies, used as filtering materials or as boundary layers in surgical masks.
Current students: Ashley Gilliard (‘14), Allison Reitmayer (‘14) and Elaine Zhong (‘14)
