​Peter Drzewiecki is a sedimentologist/stratigrapher and a professor at Eastern Connecticut State University with a BS degree from the University of Notre Dame (1989) and MS and PhD degrees from the University of Wisconsin-Madison (1992, 1996). He was employed by ExxonMobil’s Research Lab from 1996 through 2002, when he left to become a professor at Eastern Connecticut State University. At Eastern, he has earned an Excellence in Service Award (2010), Eastern Teaching Award (2012), CSU Teaching Award (2012), and ECSU Distinguished Faculty Award (2017). His research includes understanding continental depositional systems of the Hartford Basin, especially around Dinosaur State Park, and investigating the halokinetic and tectonic controls on Cretaceous carbonate platform evolution in NE Spain
In addition to chairing the Academic Advising, Sabbatical Leave, and First-Year Program committees at Eastern and directing its Honors Program, Peter has served as Secretary of the Limnogeology Division of the Geological Society of America from 2007-2012. He led field trip for the New England Intercollegiate Geological Conference and Geological Society of America in 2012, 2015 and 2021. He has been a leader in the town of Mansfield’s Boy Scout Troop since 2011, including serving as Scoutmaster for the past 5 years.
Christoph Geiss is a Professor of Physics and Environmental Science at Trinity College and has served as Trinity’s Environmental Science Program Director for the past 9 years. Christoph earned a Master’s degree (Diplom) in Geophysics from the Ludwig Maximilians Universität  in Munich, Germany, before he came to the United States where he completed his PhD in Geophysics at the University of Minnesota. After a short postdoc stint, he arrived at Trinity in 2001. Christoph is a rock magnetist who uses the magnetic properties of soils, sediments, and rocks to reconstruct past environments. His research projects, which all involve undergraduate students, focus on the use of paleosols as paleoclimate proxies, 
the reconstruction of Arctic environments using lake sediments, and most recently, the effects of natural and prescribed fires on the soils along the forest-prairie boundary in western Iowa. At Trinity he turned into a jack-of-all-trades, teaching everything from introductory geology and environmental science courses to advanced classes in soil science, climate change and geophysics as well as calculus-based physics for engineers and aspiring medical doctors.

Jean Crespi grew up in cratonic North America, seeing real topography for the first time as a teenager on a trip to the Great Smoky Mountains. That first impression stuck. Jean went on to become a structural geologist and focus her research on the Appalachians, albeit to the north in Vermont and New York State. Jean completed her undergraduate studies at Wellesley College and shortly thereafter headed west 
for graduate school, receiving her MS degree from the University of Arizona and her PhD from the University of Colorado, Boulder. Before arriving at the University of Connecticut, where she has been a faculty member for nearly thirty years, she spent time as a postdoctoral researcher at the USGS  in Reston, Virginia, at Brown University, and at the Ocean Research Institute in Tokyo, Japan. She has been active with the Northeastern Section of the Geological Society of America, giving back to the community of geoscientists in Connecticut by serving as general chair of the 2012 GSA Northeastern Section Meeting in Hartford and field trip chair for the virtual 2021 GSA Northeastern Section Meeting originally scheduled for Hartford. Her research in Connecticut has mainly been on the tectonic evolution of the Hartford basin, as seen through the lens of fault-slip data. She is a founding member of the Geological Society of Connecticut.

Ralph Lewis is a certified Professional Geologist with 39 years of professional experience; State Geologist of Connecticut between 1997 and 2003. Professor in residence, Marine Sciences Department, UCONN-Avery Point; Member Connecticut Academy of Science and Engineering; Former member of the Ocean Studies Board of the National Academies; Recipient of Dr. Sigmund Abeles Award for “Outstanding Service to Science Education in Connecticut”.  In 2014, Ralph authored a chapter on the geology of Long Island Sound in the Springer Book Series entitled "Long Island Sound Prospects for the Urban Sea." He is presently the GSC president.
Shawn Poff, P.G. is a Senior Associate and Regional Exploration Manager at Terracon Consultants, Inc. As REM, Shawn oversees Terracon’s subsurface exploration operations in New England and the Mid-Atlantic region. He is a Licensed Professional Geologist in New Hampshire, New York, and Pennsylvania. Shawn has worked in the private consulting industry for nearly 25 years, serving as Chief Field Geologist and Senior Engineering Geologist before moving into exploration management.  He holds a B.S. in Hydrogeology from Rensselaer Polytechnic Institute and an M.S. in 
Environmental Science from the University of New Haven.  Shawn enjoys outdoor activities, reading, traveling, and cheering for the Minnesota Vikings.
Melissa Mostowy graduated with her undergraduate degree in Earth Science – Secondary Education from Central Connecticut State University and a master’s degree in Earth and Environmental Science from Wesleyan University. As a student, Melissa’s research focused a provenance study of sediment in the Hartford Basin through detrital zircon analysis, a paleo-climate study of Antarctic bottom water through grain size and spectral analysis, and a compositional analysis of Martian sediment using spectral data. Concurrent with her master’s degree, Melissa interned at the Department of Energy and Environmental Protection as a GIS Analyst. Following her internship, Melissa began her professional career 
as a field hydrogeologist at Fuss & O’Neill where she worked on environmental remediation projects. Currently, Melissa is a Natural Resource Specialist for the Southwest Conservation District where she works with municipal, state, and federal employees as well as private residents regarding natural resource concerns throughout Fairfield and New Haven counties. ​

Connecticut Avery Point campus. In her spare time, she enjoys photography and exploring the outdoors with her family.
Janet Stone is a Research Geologist in the Eastern Geology and Paleoclimate Science Center, currently serving as Project Chief for the Quaternary Stratigraphic Framework of Massachusetts and part of southern Michigan (QSFM) Project.  Janet joined the USGS in 1972 and her career accomplishments include: the development of a methodology for mapping the three-dimensional distribution of textural variations within glacial meltwater deposits in New England at quadrangle-scale; synergistic analysis of the offshore marine record in Long Island Sound with Connecticut's terrestrial Quaternary stratigraphy to produce an integrated interpretation of glacial, deglacial, and postglacial events including Holocene 
sea-level rise; and recognition and study of potential permafrost-related structures formed on glacial surfaces in southern New England that have important paleoclimatic implications. Janet also spent ten years working in the Water Resources Discipline working to develop the methodology for delineation of bedrock lithology, structure, and fracture geometry at a scale that is useful for hydrologic analysis and to assess the geohydrologic factors that support current and future water-supply and ground-water contamination studies in glaciated crystalline-bedrock terrain. Janet was instrumental in the creation of the Geological Society of Connecticut and has served as that organization's President and is currently Past President.
