Dr. Arthur Chadwick is a Research Professor of Biology and Geology and co-Director of the Dinosaur Science Museum and Research Center at Southwestern Adventist University. He has done research on a variety of subjects, including systematic analysis of the geologic column in the Colorado Basin. He also co-directs a taphonomic study at one of the largest dinosaur bone-beds in the world. He has conducted geological research at the Grand Canyon, Yellowstone National Parks, in Peru on fossil whales and on the global circulation patterns through time. Dr. Chadwick is the author of numerous scientific papers as well as co-author of a science textbook. He is a cofounder of the Earth History Research Center and currently serves as Director of the Center. He was born in California, where he received his undergraduate education at San Diego State University and La Sierra College. He earned his Ph.D. from University of Miami, followed by additional work in Geology at the University of California. Before working at SWAU, he was Visiting Professor of Geology and Geophysics at University of Oklahoma. Dr. Chadwick is married to Joy Chadwick, who is a ceramics teacher at SWAU. They have two adult children, Dan and Barbara, who are both active physicians.
