Rafael Moras, Ph.D., P.E., joined St. Mary’s University in 1990. He earned his bachelor’s in Industrial and Systems Engineering from Monterrey Tech (Mexico). His master’s and doctoral degrees in Operations Research and Industrial Engineering are from The University of Texas at Austin.

His areas of interest are lean six-sigma and professional ethics. Moras has published articles in engineering journals such as Production and Inventory Management Journal, the Journal of Applied Mathematics and Computation, Production Planning and Control, and International Journal of Industrial Engineering. He is a sought-after speaker and has delivered papers and keynote presentations in more than 50 national and international professional conferences.

He offers consulting services and workshops in the areas of lean and six-sigma quality, professional ethics and the delivery of effective presentations. In 2020, Moras published “The Internship: An Engineering Ethics Novel” which features the adventures of four engineering students who face layered dilemmas dealing with professional ethics and principles as they embark on an industrial internship.

Moras formerly served as Graduate Program Director and Director of the St. Mary’s Pre-Freshman Engineering Program (PREP). He serves as one of the Department’s liaisons with local industry in our efforts to guarantee that all the senior design and graduate capstone projects conducted by engineering students are conducted in conjunction with an industrial internship.
