Evolving from my initial and ongoing interests in the treatment and removal of hazardous materials from drinking and groundwater, my personal research interests span a breadth of topics under the broad theme of sustainability. These include pollution prevention, physical-chemical processes, nanotechnology, air and water treatment, mass transfer, and numerical methods. With insight gained into how these processes interconnect with each other, and with people, markets, and nature, I am most interested right now in tools and educational programs that connect social decision making, regional development, material flows, energy use, and local, regional, and global environmental impacts.
