We are interested in making unique combinations of biological molecules and polymers to develop materials that combine the exquisite specificity and functionality of biological molecules with the physical toughness and engineering ability of polymers. We have chosen block copolymers as mimics for lipid molecules and membrane proteins as the functional protein elements.
The short term goal of our group is to understand protein polymer interactions and develop devices and membranes inspired by cell membranes. The longer term goal is to emulate these native biological structures with robust polymeric or engineered protein structural elements.
Given the PI's background in industrial research into membranes for water and wastewater treatment, we are very interested in improving current synthetic membranes used in the process, water, energy, and biotech industries with a heavy focus on water treatment, reuse and desalination. We are utilizing innovative methods to study structure of and transport across these membranes and developing new methods to control fouling and improve efficiency.
The first three papers to be published in 2017 from our group represent our seemingly diverse but ultimately integrated research perfectly. These papers represent our intersecting interests in the biophysics of transport in biological membranes, the fundamental challenges of integration of these proteins and their mimics into scalable materials, and the use of the knowledge gained from the above fundamental studies and our process expertise to improve water purification (and other) technologies.
1. Understanding transport in aquaporin 0, the “slow” water channel present in mammalian eyes, and demonstrating a 40x increase in transport rates using two key mutations. Biophysical Journal (accepted).
2. Integrating enzymes with electrodes. In this review we discuss Biomimetic and Bioinspired ideas for integrating redox enzymes including membrane proteins with polymers, lipids and electrodes. Energy and Environmental Science.
3. A review on the current status of membrane desalination, and new ideas to move this field forward including channel-based membranes, fouling resistant membranes, and desalination powered by renewable energy. It also summarizes the challenges of concentration polarization, brine disposal and oxidation resistant desalination membranes. The Bridge, National Academy of Engineering.
