I believe the only Ph.D. offer at the Missouri University of Science & Technology (MUST) was Ph.D. in System Engineering via distance learning before the COVID-19 pandemic. Now, the university also offers: - Ph.D. in Aerospace Engineering - Ph.D. in Computer Engineering - Ph.D. in Computer Science - Ph.D. in Electrical Engineering - D.E (Doctor of Engineering) in Civil Engineering - Ph.D. in Engineering Management - Ph.D. in Explosives Engineering - Ph.D. in Mechanical Engineering - Ph.D. in System Engineering https://distance.mst.edu/distance-programs/distance-graduate-degrees/
