معرفی
Timothy G. Fisher is a Professor of Geology at the University of Toledo within the College of Natural Sciences and Mathematics. His research and teaching focus on Quaternary geology, glacial geomorphology, and Great Lakes paleohydrology.
- Ph.D., University of Calgary (1993)
- M.S., Queen's University
- B.S., University of Alberta
Research Interests:
Dr. Fisher specializes in reconstructing the history of glacial Lake Agassiz, including its discharge patterns linked to climate triggers like the Younger Dryas. He investigates Great Lakes paleo-level variations driven by glacio-isostatic adjustment and climatic factors, and studies sand dune activation mechanisms along Great Lakes coastlines. His work integrates sedimentology, stratigraphy, and geophysical methods to understand subglacial meltwater dynamics and landform genesis.
Recent Publications:
His 15 most recent articles (2023-2013) examine subglacial tunnel channels, paleo-drought impacts on dune systems, deglacial retreat rates of the Laurentide Ice Sheet, and geochemical fingerprints of glacial lake sediments. Key themes include catastrophic flood deposits, OSL dating applications, and Holocene climate-lake level interactions.
Students:
- Current: Thomas Zych (MS 2020-) studying Maumee River terrace chronology
- Past: 18 MS graduates (1987-2023) with theses on topics like tunnel channels, strandline analysis, dune activity, and glacial stratigraphy
- Alexander Sodeman (2020) - Fulbright Scholar
- Melinda Higley (2009) - Ph.D. at UIUC, now Assistant Professor at Calvin College
- Henry Loope (2006) - Research Glacial Geologist at Indiana Geological Survey
