Welcome to my website, which describes my research, teaching, and service at the University of Colorado Denver since 2005. I invite you to explore the Publication, Research,
Service, and Teaching tabs above, or for complete details, please consult my curriculum vitae.
My group applies ideas from complex systems science to flow in porous media: Aquifers, soils, and granular media filters. The premise for this approach is that advances in porous media technology—such as groundwater remediation, aquifer storage and recovery, or geothermal energy—are possible using simple ideas from complex systems science. In particular, we study how the fractal dimension of colloid deposits controls permeability, and we use chaotic advection to amplify plume spreading for accelerated chemical reactions in porous media.
My group has also been active in other environmental and water resources research, including the greenhouse gas footprint of natural gas, contaminant transport in urban watersheds, and water administration in Colorado.
My research program has received over $1.2 million in external funding to date, including support for collaborators. Granting agencies include the U.S. National Science Foundation, the U.S. Department of Energy, and the Colorado Department of Public Health and Environment.

It has been my honor and privilege to teach hundreds of students since 1995 when I joined Teach for America. My current teaching portfolio includes fluid mechanics, water supply and distribution systems, and hydrology (surface water, groundwater, and vadose zone).
