Thomas receivedthe honor in recognition <strong>of</strong> his distinguished contributions tothe geosciences over nearly four decades <strong>of</strong> research, teachingand service to the pr<strong>of</strong>ession.Thomas, a paleontologist who began teaching at F&M in 1975,was previously elected a Fellow <strong>of</strong> the Paleontological Society.Named the “most influential pr<strong>of</strong>essor” in the natural sciencesby a recent graduating class at F&M, he has also contributedin numerous pr<strong>of</strong>essional-service capacities through the years,including terms as secretary <strong>of</strong> the Paleontological Society andas chair <strong>of</strong> the History <strong>of</strong> Geology division <strong>of</strong> GSA.“The surprise came when I was nominated,” Thomas says.“In part this is recognition <strong>of</strong> my pr<strong>of</strong>essional service work, Ibelieve. I’ve been involved with the GSA in a number <strong>of</strong> ways.It’s a very nice honor.”Thomas was nominated for the award by Stephen Rowland,pr<strong>of</strong>essor <strong>of</strong> geology at the University <strong>of</strong> Nevada, Las Vegas, apaleontologist and long-time colleague. “In addition to being asuperb paleontologist and scholar, Roger has been a workhorse for pr<strong>of</strong>essional organizations,” Rowland says.Thomas has conducted research on a wide variety <strong>of</strong> topics, from the growth and function <strong>of</strong> animal skeletons tothe evolution <strong>of</strong> arcoid bivalves. The intellectual theme <strong>of</strong> his work centers on patterns, processes and the evolution<strong>of</strong> complexity in nature. He began to develop his research interests at Harvard University, where he earnedhis Ph.D.Thomas worked on his dissertation under the supervision <strong>of</strong> renowned paleontologist Stephen Jay Gould.“Steve was enormously influential for me,” Thomas says. “The opportunity to work with him was a tremendouslylucky break. He helped me develop my interest in evolutionary ideas and processes. Our work and ideasdiverged later on, but we kept in touch and he visited F&M on several occasions over the years.”Thomas’ research took him to the University <strong>of</strong> Tübingen in Germany, where he developed the concept <strong>of</strong> “skeletonspace.” This work addresses patterns <strong>of</strong> exploitation in potential skeletal designs, resulting in an articlepublished in Evolution. Subsequent application <strong>of</strong> this concept to study <strong>of</strong> the emergence <strong>of</strong> the earliest animalskeletons led to a paper, co-authored with two F&M students, that appeared in Science.Thomas is most proud <strong>of</strong> his work with <strong>Franklin</strong> & <strong>Marshall</strong> students. In 1982, he received the Lindback Awardfor Distinguished Teaching, the College’s highest award to a faculty member for teaching.“I bring enthusiasm to the classroom, and I try to transmit some <strong>of</strong> the many interesting and significant thingsI’ve learned in a long career,” Thomas says. “I chose to come to F&M instead <strong>of</strong> going to a large university forthat reason. I’ve always seen myself as a teacher.”Thomas joins Pr<strong>of</strong>essor <strong>of</strong> Geosciences Dorothy Merritts as GSA Fellows from <strong>Franklin</strong> & <strong>Marshall</strong>.

The pr<strong>of</strong>essors won the awardfor their groundbreaking research paper titled “Natural Streamsand the Legacy <strong>of</strong> Water-Powered Mills,” which appeared inScience in 2008.The Kirk Bryan Award is presented annually for a publication <strong>of</strong>distinction that advances the science <strong>of</strong> geomorphology or Quaternarygeology. F&M has a longstanding connection to the award;Merritts and Walter join former pr<strong>of</strong>essor Richard Waitt (1987recipient) and Milan Pavich ’69 (1991 recipient) as winners withties to the College. In addition, former F&M geology pr<strong>of</strong>essorJohn Moss was a student <strong>of</strong> Kirk Bryan’s at Harvard University.“It’s such an honor to be recognized by your peers,” Walter says.“We’re pleased and humbled to be part <strong>of</strong> F&M’s connection tothe award. This really helps to establish our work as importantand opens new avenues <strong>of</strong> research.”Associate Pr<strong>of</strong>essor <strong>of</strong> Geosciences Robert Walter’75 (left) and Pr<strong>of</strong>essor <strong>of</strong> Geosciences DorothyMerritts (right), display their Kirk Bryan Award atthe annual Geological Society <strong>of</strong> America meetingin Minneapolis in October.

They determined that tens <strong>of</strong> thousands <strong>of</strong> mill dams once existed in Pennsylvania, Maryland and othermid-Atlantic states, forming slackwater ponds that trapped sediment over a period <strong>of</strong> centuries. Sedimentreleased by the aging dams has lowered the water quality in the Chesapeake Bay, which was declared an impairedwater body in 2000 by the U.S. <strong>Environment</strong>al Protection Agency.Ellen Wohl, pr<strong>of</strong>essor <strong>of</strong> geology at Colorado State University, nominated Walter and Merritts for the KirkBryan Award. In the award citation, Wohl credits the pr<strong>of</strong>essors for challenging assumptions about river formand stream restoration.“By demonstrating that the floodplains are actually historical fill terraces and that the streams are not naturalarchetypes for gravel-bed, meandering streams, Walter and Merritts have provided an opportunity for members<strong>of</strong> the stream-science community to reevaluate long-held assumptions about stream processes and form, thehistorical influence <strong>of</strong> humans on streams, and appropriate models for stream restoration,” Wohl says.Merritts and Walter are conducting most <strong>of</strong> their current research at Big Spring Run, a meandering stream thatflows through farmland near Willow Street, Lancaster County. The pr<strong>of</strong>essors recently worked with state andfederal agencies on a high-pr<strong>of</strong>ile project to restore the landscape’s original function—and, they hope, improvewater quality in the Chesapeake.The project has enabled Merritts and Walter to introduce F&M students to new areas <strong>of</strong> research.“It’s exciting to be able to take students to the field any day <strong>of</strong> the week,” Merritts says. “I used to buy planetickets and take two or three advanced students far afield for a few weeks <strong>of</strong> summer research. Now studentsfrom introductory to advanced classes can participate in the local project throughout the year. Students get anintense immersion into hands-on learning. They become high-capacity researchers.”Merritts and Walter are currently on sabbatical at Stanford University as Allan Cox Visiting Pr<strong>of</strong>essors for the2011-12 academic year. They look forward to continuing their research at the newly restored Big Spring Runwhen they return to Lancaster; the pr<strong>of</strong>essors will monitor geomorphic changes over time to determine if theproject has resulted in a reduction <strong>of</strong> suspended sediment in the water. “We know <strong>of</strong> no other stream beingstudied in such detail,” Walter says.“This will last our lifetime. We’ll never be done with it,” Merritts says. “It’s transformed our work.”
