I study the interactions between geology and biology throughout Earth’s past using sedimentology, petrography, geochemistry, and microbiology. I completed my Ph.D. at the University of Southern California in 2018, and I am currently an assistant professor at Grand Valley State University in Grand Rapids, Michigan. https://images.squarespace-cdn.com/content/v1/5d2b4575182c070001fbf845/1645003157424-CDF1WBH1TP6PTNXUEWS0/20181019_160201_HDR.jpg Home https://www.dylanwilmeth.com/current-projects daily 0.75 2020-10-12 https://images.squarespace-cdn.com/content/v1/5d2b4575182c070001fbf845/1563219893597-2OMT3Z2W4XH2IUVP78AJ/20190421_153503.jpg Current Projects -
