About

Our research focus is biophysical materials chemistry. We work at the interface of physical and biological sciences in the realm of materials science. We utilize biophysical tools and bio/synthetic architectures toward two main goals: 1) understanding complex processes of living systems through investigation of model assemblies, and; 2) understanding bio-synthetic interfaces toward integrating biological design into materials development.

Ongoing Lab Project:
Bio-inspired supramolecular membrane materials: Typically, supramolecular biological membrane systems exist in non-equilibrium states necessary to perform their complex biological functions. A focus of our research team in this area is mimicking such  non-equilibrium design and functionality in (bio)synthetic materials design. Our designs are typically based upon amphiphilic block-copolymer supramolecular assemblies capable of dynamic, non-equilibrium organization and bio-like functionality.

Biological Membrane Dynamics:Supported lipid membranes provide a useful platform for interrogating biological membrane interactions and interfaces. A focus of our research team in this area is the investigation of biological membrane processes using supported lipid membranes as a platform for interrogation. It is possible using such platforms to understand complex membrane activities in a controlled environment.

Scanning Probe Force Applications Development: Scanning probe microscopies have proven an effective means of interrogating dynamic interactions. Our research focus in this area is in developing platforms that allow for interrogating dynamic materials interactions at the biological and bio-synthetic interfaces.
