Cherie Miller

Cherie Miller is a Technical Specialist in the Office of Water Quality and has been with the U.S. Geological Survey for over 20 years. Her main interests are in stream geochemistry, particularly in trace metal cycling and modeling. 

Biography

 

Cherie's research has focused on continuous and real-time water quality, developing surrogate log-linear regression models to estimate parameters of stream chemistry and to understand stream processes and ecology. Managing and exploring water-quality data has been a special interest and she has developed a national USGS class to enhance our footprint in the realm of water quality; the class is the QW Data Toolbox for NWIS Users.

While at USGS in the early 1990s, Cherie was the project chief of the Chesapeake Bay Fallline Toxics Program and the Surface-Water Specialist for the Potomac NAWQA pilot. From 1996 to 2010, she was the Water-Quality Specialist for the MD-DE-DC Water Science Center. Her studies have included modeling of nutrient and sediment loads, modeling processes in urban streams, new technology for continuous monitoring of water quality in streams, toxics in streams including metals, pesticides, and organic wastewater chemicals from the human-waste stream, and fish ecology in urban streams. Cherie was an Associate Director for the Center and supervises two science teams - the Water-Quality Monitoring and Modeling Team, and the Fate and Bioremediation Team.

Cherie's background is interdisciplinary with a bachelor’s degree in biology from Rollins College in Winter Park, Florida, an M.S. in Environmental Science from the University of Virginia, an M.A. in hydrogeology from Johns Hopkins University, and a Ph.D. in Chemistry from the University of Maryland in College Park. At the University of Virginia and under the direction of Dr. Mahlon Kelly, Cherie studied the bioavailability of iron sesquioxide-bound phosphates to phytoplankton in Peacock Hill Lake, Charlottesville, Virginia. At the Johns Hopkins University, in the Department of Earth and Planetary Sciences, Cherie studied thermodynamics and geochemistry under the tutelage of Dr. Hans Eugster and worked on the mobility of copper, lead, and zinc from red bed sandstone formations during diagenesis. At the University ofMaryland, Cherie and Dr. George Helz documented a history of water-column anoxia in the Chesapeake Bay using profiles of molybdenum in sediment cores. Molybdenum is sequestered from the water column in the form of ferrothiomolybdate solids during anoxic events and is deposited to the sediments. The structural forms of the solids that are formed in this process were examined using EXAFS and found to be similar to some cubane Fe-Mo-S structures found in nature, such as in nitrogenases. Also, as part of this research, Cherie worked on the history of sedimentation rates in the Chesapeake Bay collaborating with Dr. Grace Brush at Johns Hopkins on pollen-dating techniques and with Dr. Jeff Halka at the Maryland Geological Survey on coring. Some very interesting work has continued from her dissertation at the University of Maryland with other graduates students of Dr. Helz, including Brit Erikson and Jordan Adelson.

In 1992, Cherie graduated from the University of Maryland at College Park and took a temporary position for two years to teach environmental science, hydrology, and geochemistry at Franklin and Marshall Collegein Lancaster, Pennsylvania. During this time, she began her career as a scientist at the USGS and has continued at USGS to the present.
