Matthew Weldon, Board Member
Matt - head shot

Matthew has worked in the semiconductor industry for manufacturers of semiconductor process equipment and metrology tools, and enjoys technology startups. He currently works at the UT Pickle Research Campus in an National Science Foundation-funded engineering research center focused on nanomanufacturing systems development. He has BS and MS degrees in Chemical Engineering from the Universities of Colorado (Boulder) and California (Davis) respectively. Between these educational pursuits he spent over 2 years in Central America with the Peace Corps constructing gravity fed potable water distribution systems. These experiences make him appreciate that fossil resources are too valuable to merely burn when they have so many other unique uses, especially when our current market design socializes their negative consequences. Water too is too precious to casually place at risk in fossil fuel recovery in the absence of indemnification for people and ecosystems reliant on at risk waters. Promoting solar energy utilization is thus a natural interest.
