Dave Bailey

Professor of Geosciences


David Bailey's current research focuses on the history of igneous and tectonic activity in the northeastern United States and on the mineralogy of New York State. He is a recipient of National Science Foundation ILI and CCLI grants and is a research associate of the New York State Museum. Baily has written numerous peer-reviewed papers, conference abstracts and field trip guides. He earned his doctorate from Washington State University. His dissertation focused on geochemistry and petrogenesis of Miocene volcanic rocks in the Powder River Volcanic Field, northeast Oregon.

Nathan Goodale

Associate Professor of Anthropology


Nathan Goodale is a scientifically oriented anthropological archaeologist with interests in the origin of villages and small-scale, semi-sedentary societies as well as technological adaptations. He specializes in the rise of complex hunter-gatherers in the interior Pacific Northwest, the forager/farmer transition in Southwest Asia and rural coastal adaptations in western Ireland. His research emphases include paleodemography, technological adaptations, modeling human behavior with quantitative methods, lithic technological organization and geochemical spatial analysis, all couched in an evolutionary theoretical framework to understand human behavior. He earned his doctorate in anthropology from Washington State University.

Zach Osborne

Director, Hamilton Analytical Lab


Zach became the Hamilton Analytical Lab (HAL) Director in 2022 and is responsible for instrument operation and data analysis. He earned his doctorate from Syracuse University where his dissertation combined experimental mineralogy & petrology with geochemical analyses (EMPA, Raman, XANES) in development of trace element thermobarometers for titanium in silica minerals (Ti-in-Quartz and Ti-in-Coesite). Before Syracuse, Zach earned a B.S. in Geology from St. Norbert College and a M.S. in Geological Sciences from Indiana University – Bloomington. Outside of the lab, Zach enjoys cheering on the Green Bay Packers, hitting golf balls at the driving range, playing board games with friends, tasting craft beers, and tracking down fresh, squeaky cheese curds.

Brandi Langsdorf

Assistant Technician


Brandi joined the group in the summer of 2022. While new to geosciences, her background in analytical chemistry makes her a strong addition to our team. Brandi began her academic endeavors earning a B.A. in chemistry from Cornell College, IA, followed by a Ph.D. in chemistry from the University of Oregon . Throughout her career she has applied a wide variety of analytical techniques to assess structure property relationships in both small and large molecule systems. Brandi's main contributions to HAL are in the areas of sample preparation and student management. Brandi enjoys strong coffee, an unexpected pun, and is always up for a game of ultimate frisbee.

Richard Conrey

External Consultant

Rick is a geologist with interests in the volcanic and tectonic history of the Cascade arc of the Western U.S. With personal XRF data collected over more than three decades (he first ran a Norelco XRF spectrometer in 1982), he has a vested interest in data quality and evaluation of measurement uncertainty. Rick has three geology degrees, a B.S. and M.S. from Oregon State University, and a Ph.D. from Washington State University. Following completion of his Ph.D. in 1991, Rick spent a post-doc year with the Geological Survey of Japan using the K-Ar method to date young Cascade volcanic rocks from northern Oregon. Since then Rick has continued to map and acquire XRF data in the Oregon Cascade Range, both privately and as a USGS volunteer. His primary colleagues at the USGS have been Dave Sherrod and the late Russ Evarts. In 2004 Rick took over supervision of the XRF analytical service at the WSU Geoanalytical Lab, which he ran for 10 years. In 2015 he moved to Hamilton College and is the head technician at the newly established Hamilton Analytical Lab (HAL). Rick enjoys sculling and sweep rowing, cross country skiing, reading, and hoppy beers, not necessarily in that order.
