Biography

Juan Ocampo, Ph.D., is an Associate Professor of Mechanical Engineering in the St. Mary’s University Engineering Department. He joined St. Mary’s in August 2016.

Ocampo received his Ph.D. in Mechanical Engineering from the University of Texas at San Antonio (UTSA) in 2013. He also received his M.S in Mechanical Engineering from UTSA in 2009. He came to the United States from Medellin, Colombia, where he received his B.S. degree in Mechanical Engineering from EAFIT University.

Ocampo’s main research area is Holistic Structural Integrity Process (HOLSIP) with an emphasis on structural integrity (probabilistic fatigue and damage tolerance analysis). He has active research grants with the Federal Aviation Administration in structural integrity and with the National Nuclear Security Administration Minority Serving Institution Partnership Program (NNSA MSIPP) to build a pipeline between the Department of Energy’s sites and labs and minority-serving institutions in STEM disciplines and bring a heightened awareness of NNSA plants and laboratories to institutions with a common interest in STEM research fields.

Ocampo also performs consulting activities for the industry, where for example he supported the development of the Pilatus PC-24 business jet. Ocampo is very active in the structural integrity and aging aircraft community where he frequently presents and publishes his work at different national and international conferences.
