Erik’s areas of expertise are carbonate sedimentology and stratigraphy, and karst. His current areas of research interest involve Quaternary carbonate environments, carbonate island hydrology and geology, karst mapping techniques and technology, high latitude/glaciated karst, and the mid-Silurian geology of the Michigan Basin. Outside the classroom, Erik enjoys hiking, rock/mineral/fossil collecting, camping, reading, listening to music, railfanning, watching science fiction TV shows, and spending time with his critters.
