Members of the Dibb, Greenslade, and Griffin research groups during a recent group meeting. The attire of many members should indicate that we often talk about sports more than we do about science (GO PATS!). Front row: Meredith Cleveland (MS Earth Sciences), Jack Dibb (Research Associate Professor), Carolyn Jordan (Research Scientist), Luke Ziemba (PhD NRESS). Back row: Alexis Attwood (PhD Chemistry), Kabindra Shakya (PhD NRESS), Jeff Luxford (MS Earth Sciences), Rob Griffin (Associate Professor), Phil Place (MS Earth Sciences), and Meg Greenslade (Assistant Professor).
