The Team

Marine Frouin

Marine Frouin

Assistant Professor

Dr Frouin is the director of the Stony Brook Luminescence Dating Research Laboratory. In addition to the Department of Geosciences, she is affiliated with the Turkana Basin Institute, and part of the Interdepartmental Doctoral Program in Anthropological Sciences. She is also a research associate at the Research Laboratory for Archaeology and the History of Art at Oxford University (U.K.). Dr Frouin research is focused on the development and application of luminescence dating techniques, an absolute chronometer that is almost universally applicable to any sediment that has been exposed to daylight during transport. It is a major chronometric tool for late Quaternary studies, with a wide age range from a few years up to about 0.5 Ma, with some indication that this limit can be further extended. She has >15 years of experience working in the field in North and South America, Africa, Asia and Europe.

Graduate Students

Taylor Grandfield

Taylor Grandfield

PhD Candidate

Taylor is learning the methods and principles of luminescence dating while exploring the various geological and archaeological applications. She graduated from Stony Brook University with a B.S. in Geology and was heavily involved in undergraduate research. Her research used geophysical field techniques, mainly Ground Penetrating Radar (GPR), to understand local barrier island morphology and sediment characteristics. She completed an undergraduate thesis titled ‘Velocity Constraints and Sedimentary Analysis in Robert Moses State Park, NY using Ground Penetrating Radar’.

Roheyatou Ceesay

Roheyatou Ceesay

PhD Candidate - Dr. W. Burghardt Turner Fellow

Roheyatou is learning the methods and principles of luminescence dating while exploring the various geological and archaeological applications. She graduated from Macalester College with a BA in Geology with an emphasis in Classical Archeology. Her main interests are geochronology and geomorphology!

Victoria Castle

Victoria Castle

PhD Candidate

Victoria research uses Optically Stimulated Luminescence (OSL) dating to reconstruct the chronology of archaeological sites and investigate environmental change across North and South America during the transition from the Last Glacial Maximum. She is particularly interested in understanding the causes of variability in luminescence behavior among quartz and other silica polymorphs.

Her broader research interests span geochronology, paleoclimatology, geomorphology, and global environmental change. In addition to her scientific work, Victoria is passionate about fostering creative and inclusive STEM mentoring experiences for undergraduate, high school, and graduate students.

Leland Reisfield

Leland Reisfield

MS student

Leland is learning the methods and principles of luminescence dating while exploring the various geological and archaeological applications. He graduated from the University of Maryland Baltimore County with a B.S. in Biochemistry and Molecular Biology. Leland is currently involved in a project to use luminescence to date portions of the Lobolo Formation in the Turkana Basin, Kenya.
