Peter Flawn Professor

Cellular and Tissue Engineering Laboratory
Department of Biomedical Engineering

Educational Background:

  • B.S. Ch. E. Cum Laude, University of Massachusetts
  • M.S. Ch. E., California Institute of Technology
  • Ph.D., Massachusetts Institute of Technology

Areas of Teaching Interest:

  • Tissue-Biomaterial Interactions;
  • Cellular Engineering;
  • Tissue Engineering;
  • Biocompatibility

Areas of Research Interest:

  • Cellular and Tissue Engineering
  • Tissue regeneration
  • Biomaterials (including nanostructured ones)
  • Mechanisms of cellular responses to stimuli (chemical, mechanical, magnetic, electrical)
  • Biocompatibility (specifically, cell/biomaterial interactions)

Description of Research:

The research activities of my laboratory have focused on the aforementioned areas. For this purpose, information and insight that have become available through recent advances in a number of disciplines such as cellular/molecular biology, biochemistry, materials science, etc., has been utilized. Examples of such endeavors include: modification of material surfaces with immobilized, bioactive compounds such as select adhesive peptides; micropatterning of material surfaces in order to direct and control subsequent adhesion of specific cell lines in designated domains; and novel material formulations (specifically, nanoceramics and nanocomposites) with unique biocompatibility and/or improved mechanical and electrical properties. Cellular, in vitro models have been used to evaluate the cytocompatibility of these constructs and to determine the chemical conditions and biophysical (specifically, pressure, electric and magnetic) stimuli needed to promote neotissue growth.

This research exemplifies alternative strategies and novel approaches of great potential for tissue regeneration purposes in tissue engineering and other biomedical applications.
