Bio/Research

My research is focused on the micro and nanoencapsulation of biologically active materials including cells, enzymes, nucleotides, genomic DNA, and therapeutic peptides and proteins. Encapsulation enables stabilization, retention, immunoprotection, controlled or targeted drug delivery, continuous processing, or cell growth in a protected environment. As cells, tissues and biologicals are labile, I have adapted encapsulation matrix/membrane materials and methods to involve use of natural materials such as polysaccharides and proteins, avoiding the use of solvents, pH extremes and highly reactive conditions, enabling the control of polymer matrix properties to achieve specific encapsulation goals, such as bioactive retention, controlled permeability, or triggered and/or controlled release.

My research is highly interdisciplinary and collaborative, thus my graduate students and researchers have opportunity to conduct research in collaborating labs. Active research areas are listed below, with names of collaborators.
