Research Interests

Broadly speaking, my research interests involve studying the processes that cleave silicon-carbon (Si-C) and silicon-hydrogen (Si-H) bonds of silicone polymers. Silicones are a class of plastics; the most common silicone material is polydimethylsiloxane (PDMS), which is comprised of repeating dimethylsiloxane units end-capped with trimethylsilyl groups. Depending on the number of monomer units, silicones range from low-viscosity fluids to high molecular weight gums and are used in such products as surfactants, lubricants, and sealants.

Suffolk University has a number of mechanisms through which undergraduate students can work on research projects during the academic school year, either for course credit or through paid research assistantships. Declared science majors with a minimum completion of 200-level organic chemistry lecture and lab may work on the following research projects in laboratories at Suffolk University:

  • The biodegradation of dimethylsilanediol by Arthrobacter Methylotrophus: An investigation into the biologically-mediated silicon-carbon bond cleavage process.
  • The mechanism of Zn-catalyzed carbonyl reduction by poly(methylhydro)siloxane.

Due to the interdisciplinary nature of my research, undergraduate research assistants acquire specific skills in the synthesis and characterization of molecules, analytical chemistry, and basic techniques in microbiology, in addition to a deeper appreciation for the importance of green chemistry. Students with whom I have worked on research projects in the past seven years are in scientific fields through a wide variety of professional positions or pursue graduate studies. Suffolk University undergraduate students interested in research opportunities are encouraged to email me (dwicht@suffolk.edu).
