   abstract: "My main interest is improving the analysis of hydrologic data, with\
     \ a focus on the topic of trends in streamflow and trends in surface water quality.\
     \  My research on this has resulted in the development of the EGRET software\
     \ (Exploration and Graphics for RivEr Trends) written in R and available freely\
     \ online.The focus of my research is the description and understanding of long-term\
     \ variability and change in surface-water quality and streamflow.  I develop\
     \ and apply new statistical tools to help characterize these changes to gain\
     \ the best possible understanding of the nature of the change and its implications\
     \ from a policy perspective (related to water quality improvement, flood hazard\
     \ mitigation, water supply planning). This work has resulted in the development\
     \ of the statistical method Weighted Regressions on Time, Discharge, and Season\
     \ (WRTDS), which I have applied to the study of water quality trends in a variety\
     \ of watersheds including Chesapeake Bay, the Mississippi River, Lake Erie,\
     \ and Lake Champlain. This technique is a central feature of the EGRET R package.\
     \ That package is designed to be a \u201Ctoolbox\u201D for analysis of daily\
     \ streamflow data and surface water quality data.My other major recent contribution\
     \ is the publication of \"Statistical Methods in Water Resources\" the 2020\
     \ edition published as USGS Techniques and Methods (tm4A3). In addition to the\
     \ pdf and the printed book, the text has on-line resources which include all\
     \ of the data sets used as examples in the book, all of the R code used in the\
     \ analysis of those data, and all of the R code used to produce the graphics\
     \ in the book.I hold a B.A. in Geology from Earlham College, an M.S. in Geology\
     \ from the University of Washington, and a Ph.D. in Geography and Environmental\
     \ Engineering at the Johns Hopkins University. I began my USGS career in 1976\
     \ and conducted research on water supply, water quality, pollutant transport,\
     \ and flood frequency analysis. In 1993-1994 I was Acting Director of the USGS,\
     \ and from 1994-2008 I was the Chief Hydrologist of the USGS. In 2008 I returned\
     \ to research and since that time I have focused efforts on describing long-term\
     \ changes in streamflow and water quality. I retired from the USGS in 2018 but\
     \ continue to collaborate with colleagues inside and outside the USGS. I am\
     \ a member of the Water Science and Technology Board of the NASEM and have served\
     \ on four expert committees of that Board."
