Schuller has been with Peabody since 1986 when he joined as a production supervisor, and has more than 25 years of operations and engineering experience. He was most recently SVP of engineering services for the producer.

A graduate of West Virginia University and the University of Charleston, Schuller has held various mine management positions at US operations and was general manager of underground operations and general manager of mining support for Peabody's Australian operations in Queensland.
