My research is focused on rivers and water in the US.  I am trained as a hydraulic engineer and hydrologist, but my work spans from basic field and lab science to policy and economics.  Most of my current basic science work is done through my very capable team of graduate students and post-docs, and through collaborations at the Duke River Center. My current scientific focus is on using novel approaches to studying rivers, particularly Lagrangian (flowpath) based approaches, being pioneered by Scott Ensign and John Gardner (see below).  I am also working on water infrastructure finance (municipal and federal), and through my work with the Nicholas Institute, the creation of an Internet of Water

I typically publish my research in technical/scientific peer-reviewed journal outlets, a (mostly) full list of which is available through my Google scholar page or through my Duke page. What I consider to be my key academic/scholarly contributions are listed below. I have also advised a number of stellar PhD students and post-docs (along with a large number of masters students, who are not listed here).
