Short Biography I am currently developing and implementing hydrologic hazard techniques for dam and levee safety at the U.S. Army Corps of Engineers, in collaboration with the Hydrologic Engineering Center and others. My research, project interests, and expertise in hydrology include: extreme flood understanding, estimation and prediction; rainfall-runoff modeling; flood frequency; paleoflood hydrology; stochastic hydrology; and risk analysis. I also have experience and interests in extreme storm rainfall, stochastic storm transposition, rainfall frequency, Probable Maximum Precipitation, and hydrometeorology. From 1997 to 2015, I developed and applied probabilistic flood hazard techniques to evaluate the risk and safety of Bureau of Reclamation dams, and oversaw implementation of risk-based flood methods for the Reclamation dam safety program. From 1991-1997, I worked as a hydrologist in consulting and performed research while in graduate school. Details are listed on my CV/Resume.

I am also heavily involved in ongoing Federal efforts to improve guidelines and techniques for flood frequency and extreme storm rainfall, in collaboration with NOAA and others. Along with colleagues at USGS, USACE, and Cornell University, I revised the US National Flood Frequency Guidelines to Bulletin 17C. I am also working on improving extreme storm rainfall data bases and precipitation frequency methods for evaluating critical infrastructure.

One purpose of this website is to share information (articles, reports, software, etc.) and communicate ongoing activities on extreme floods and hydrologic hazards. The goal is to improve tools and data sets used in hydrologic engineering practice. See the Resources page for some training courses, software, and data.
