About Me


I have been working with membranes ever since I graduated from the UT in 2007. After working for several years in industry at Pentair X-flow, I had the opportunity to come back to the university. Here, I was involved in a successful start-up company (NXFiltration) that now makes and sells the next generation of nanofiltration membranes.

At the Membrane Science and Technology Cluster I specialize at integrating membranes into processes, an topic where my industrial experience proves to be very relevant.
