Headshot_AnneJefferson_smallforwebAnne Jefferson grew up on the Mississippi River in southeastern Minnesota and spent summers on Lake Superior. These two places imbued her with a love of water and the dynamic way it shapes landscapes. Anne completed her undergraduate degree at Johns Hopkins University, an MS in Water Resources Science from the University of Minnesota, and a PhD in Geology from Oregon State University. While Anne was on the faculty of UNC Charlotte from 2007-2012, she became convinced that urban watersheds were fascinatingly complex and worthy of more scientific attention. In 2012, she joined the faculty at Kent State University as part of a cluster hire focused on urban water and ecosystems. She was tenured and promoted in 2016. For 2016-2017, Anne is a Public Engagement Fellow as part of the American Association for Advancement of Science Leshner Leadership Institute. You can read more about Anne’s background in her CV and you can learn more about her research and teaching by browsing this site.

Post-doctoral Scholar

Avellaneda, PedroPedro Avellaneda joined the Watershed Hydrology group in February 2016. Pedro has a PhD in Civil Engineering from the University of New Hampshire and is on leave from a research assistant professor position in the Department of Civil and Agricultural Engineering at the National University of Colombia. Pedro is working on integrating monitoring data with watershed modeling of green infrastructure. You can read more about Pedro in his CV.


Students interested in pursuing a M.S. or Ph.D in Applied Geology starting in fall 2017 who have research interests in urban hydrology, groundwater-stream interactions, or watershed hydrology should peruse this site and the Department of Geology web pages, then please contact Anne for more information.

garrettGarrett Blauch is an M.S. student who joined the Watershed Hydrology lab in fall 2016. Garrett’s research focuses on the dynamics of wood abundance and mobility in urban streams. Garrett earned his undergraduate degree in geology from the University of Pittsburgh in 2014 and worked for an engineering firm before returning to graduate school.



caytieCatherine Ruhm joined the Watershed Hydrology lab in Fall 2016, after earning her undergraduate degree in geology from Mercyhurst University in Pennsylvania. Catherine’s research focuses on soils and geomorphology of abandoned surface mines now located in Cuyahoga Valley National Park. Catherine is co-advised by Dr. Chris Blackwood in Biological Sciences.





BuzulenciaHayley Buzulencia is an M.S. student, who started in fall 2015. Hayley’s research focuses on sulfur dynamics in an urban wetland. She is co-advised by Dr. Lauren Kinsman-Costello. She completed her undergraduate degree in Environmental Science at the University of Mount Union in Spring 2015. In summer 2016, Hayley worked on her research and served as a hydrology intern for Cleveland Metroparks. In summer 2015, she worked for Ohio EPA.

Laura’s research focuses on comparing the hydrologic and water quality effectiveness of bioretention cells and green roofs. Her work is supported by Cleveland Metroparks. She is co-advised by Dr. Lauren Kinsman-Costello. Laura’s undergraduate degree in Geology is from Illinois State University.



Stuart BakerStuart Baker is an M.S. student in Geology at Kent State University. Stuart’s thesis focuses on understanding the evolution of hyporheic exchange and nutrient uptake in restored streams. His work is supported by a grant from the USGS, through the Ohio Water Resources Center. Originally from Washington state, Stuart’s undergraduate degree is from Montana State University. Stuart is finishing his thesis while working as a Water Quality Specialist for Snohomish County in Washington.


Krista BrownKrista Brown is an M.S. student in Geology at Kent State University. Krista’s thesis focuses on groundwater-stream interactions in a post-dam removal environment. Krista’s undergraduate degree is from Kent State University in Conservation Biology. Krista works for ARCADIS in Akron as a staff geologist. 







Eric Traub earned his M.S. degree in Geology in May 2016. Eric’s thesis focused on understanding how acid mine drainage precipitate affects groundwater-stream interactions and how those interactions affect mineralogical transformations in the precipitate. He was co-advised by Dr. David Singer. Eric is now works for the US Geological Survey as a hydrologist.

Kimberly Jarden earned her M.S. degree in Geology in April 2015. Kimm’s thesis focused on assessing impacts of green infrastructure retrofits for suburban streets in Parma, Ohio. Her work was supported by Cleveland Metroparks and the US EPA. Kimm is a Senior Sustainability Specialist in the Global Sustainability Department at Goodyear in Akron, Ohio.

Allison Reynolds earned her B.S. in Geology in May 2015. Allison ran the isotope lab and completed independent research on isotopic variability of precipitation in the eastern Great Lakes Region. She presented her research at the 2014 GSA conference and a CUAHSI virtual conference in 2013. In Fall 2015, Allison began graduate school at the University of Waterloo, Canada.

Darren Reilly completed his M.S. in Geology in April 2014, co-supervised by Anne Jefferson and David Singer. Darren’s thesis research focused on sources of groundwater contamination for residential wells in northeastern Pennsylvania. He currently works for AECOM in Long Beach, California.

Sean Robertson was an undergraduate Geology major at Kent State University who contributed to field and laboratory activities in 2014. He is now a hydrogeologist at Eagon and Associates in Columbus, Ohio.

Sidney Bush joined the watershed hydrology lab as an ecology REU student for the summer of 2014. She presented her research on bioretention cell soil moisture dynamics at the 2014 AGU conference. After finishing her undergraduate degree in Environmental Science at the University of Virginia, she began a MS degree at the University of Colorado in Fall 2015.

Jillian Sarazen worked with the Watershed Hydrology lab in the summer of 2015, as part of the REU program. Her research focused on water quality effects of a green roof. She presented her research at the 2016 IAGLR conference. Jillian graduated from Oberlin College in May 2016.

Cody Unferdorfer was an undergraduate geology major assisting with laboratory and field work, including stable isotope analyses, for 2015-2016.
