I am an associate professor of Environmental Engineering at The Pennsylvania State University, University Park, PA, USA (http://LiReactiveWater.com). I am currently on sabbatical visiting the ECHO group at EPFL. My goal here is to learn / exchange tools and stimulate ideas to connect the water world and the biogeochemistry world, and of course, to enjoy food, culture, and people in the beautiful (stunningly!) Lausanne and beyond
