Brent Keller

Brent Keller is the current Chief Technology Officer at Via Separations. Brent leads the technical development of graphene oxide membrane scale up, application demonstration, and module design. The Via Separations platform technology improves selectivity between key nanofiltration solutes and enables filtration at conditions previously impossible. Brent has also worked as a Postdoctoral Research Associate and Doctoral Candidate at the Massachusetts Institute of Technology (MIT) for 5 years and 9 months. There they were responsible for the fabrication and characterization of thin film electrical devices, the study of the impact of processing on chemical structure, film morphology, and optical and electrical properties of asphaltenes and other carbonaceous materials, spectroscopic characterization of carbon materials, and leading successful teams of both colleagues and industrial collaborators. Brent also oversaw 2 MS and 3 BS students during their time at MIT. In addition, they developed an ALD based method of MoS2 deposition with precise layer control down to monolayer and studied process variables for sub 1 nm film coalescence. Furthermore, they fabricated thin films of naturally sourced carbon nanoparticles with optical and electronic properties competitive with rGO, a-C and other synthetic materials. Lastly, they characterized fundamental exciton physics in junctions between 2-dimensional (2D) materials for applications in computing, signaling, and energy harvesting. Before their time at MIT, Brent was an Undergraduate Research Assistant at the University of Minnesota for 2 years and 8 months.

Brent Keller has a Ph.D. from the Massachusetts Institute of Technology in Materials Science and Engineering. Brent also has a Bachelor of Science from the University of Minnesota-Twin Cities in Chemical Engineering and Chemistry.
