Dr. Masterlark is a Professor of Geology and Geological Engineering at South Dakota Mines. He earned his Ph.D. from the University of Wisconsin-Madison, after which he accepted an appointment to the USGS National Center for EROS and went on to accept a faculty position at The University of Alabama. His research team develops numerical simulations of magma migration, earthquakes, tsunami genesis, and geothermal systems. He authored more than 160 publications and was the Principal Investigator for numerous research grants from NASA, NSF, and USGS. He served as Associate Editor for Journal of Geophysical Research-Solid Earth. Dr. Masterlark was recently selected by the National Academies as a Jefferson Science Fellow and is the first Professor from South Dakota to earn this prestigious distinction. He serves on the advisory team for NASA's Earth Surface and Interior program and regularly serves on review panels for US and foreign scientific agencies. Dr. Masterlark is the Honorary Commander for the Munitions Squadron, 28th Bomb Wing, USAF. Prior to his academic career, he served as a paratrooper in the US Army's 82nd Airborne Division —America's Guard of Honor.

Get the Job Done


Discipline is the foundation of strength and courage. Discipline underpins the humility needed to listen and extend kindness. When we fall, discipline picks us up.

Take Responsibility.
  • Who is responsible for Your Successes? Your Failures? Look in the mirror.
  • Outraged by the behavior of others? Why don't they listen to reason? Check yourself. Nobody owes you anything. Take ownership of your life and trajectory.
Get out there and do some work.

There is only one path to success. Look to others for guidance and learn what you can, but the burden is yours. Get after it with unrelenting discipline.
