My wife, Caroline Strömberg, is a paleo-botanist at UW’s Lin at StoneroseBiology Dept. and Burke Museum of Natural History. Using phytoliths (plant silica), she studies the evolution of grasses, grasslands, and grazers. She also studies vegetational structure in the Big Cedar Ridge flora.

My brother, Jeff Wilson, is a vertebrate paleontologist at the University of Michigan, who studies sauropod dinosaur paleobiology. Although our research organisms are on opposite ends of the body size spectrum, we collaborate on field projects in India and Baja.




bill_alaska_smallMy former Ph.D. advisor, Bill Clemens, is a mammalian paleontologist at the University of California, Berkeley. The Society of Vertebrate Paleontology recently awarded him its highest honor, the Romer-Simpson Medal, for his lasting contributions to the field of vertebrate paleontology.

Eric Duneman (L) is a field paleontologist, preparator, and expedition organizer. We’ve teamed up in Niger, Baja, and India. Chris Sidor (R) is a vertebrate paleontologist at UW’s Biology Dept. and Burke Museum of Natural History.
