Research Interests

My current research activities are focused on separation processes for biopolymer processing and wastewater treatment.

Toward this end, we typically focus on microscale processes (MSP) - the study of conventional processes (e.g. chromatography, membrane filtration, adsorption) but in miniaturized formats such as micro-columns, micro-well plates, and microfluidic devices. The advantages of this approach are considerable. First, it is extremely cost-effective since it requires minimal amounts of material. Thus, it can be used to thoroughly explore the entire process design space of a process and determine the optimum operating conditions. Second, it is very efficient since it uses a parallel architecture approach. Thus, this format allows for a high-throughput development strategy instead of the more common hypothesis driven approach. Finally, integrated instrumentation can be used to monitor in real-time the process performance.

The unifying theme of our work is to develop the appropriate structure-processing relationships and mechanistic models that predict the process performance. We frequently use various bio-physical tools (e.g., light scattering, electrophoresis, circular dichroism) and microscopic techniques (e.g., scanning electron microscopy). Our work is greatly enhanced by the resources that are available at the Biointerfaces Institute and the Brockhouse Institute for Materials Research. The projects in my group are multi-disciplinary in nature and typically include collaborations with polymer physicists, micro-biologists, and chemists.

Biopolymers are a diverse and versatile class of materials including polynucleotides, polypeptides, polysaccharides, and polyesters. We are particularly interested in developing new separation processes that solve the technical and economical challenges associated biopolymer production at various scales.

Our interests in wastewater lie at the water-energy nexus. This includes the treatment of water from hydraulic fracturing operations for natural gas production, as well as water demands in renewable energy (e.g. bio-gas) production. A list of current (as of September 2016) research projects related to wastewater treatment are given in the table below.
