Mena graduated with a bachelor's degree in mechanical engineering from the National Autonomous University of Mexico (UNAM, 1964); specialized in Fluid Mechanics at the University of Toulouse (France, 1967); and earned both a master's degree and a Ph.D. in mechanical engineering from Brown University (United States, 1969–1973),[2] where he also received the Brown Engineering Alumni Medal in 2000.[3]

He has developed several patents, including an oscillatory die for polymer extrusion used by the henequen industry in the Yucatan peninsula and an hexagonal solar-powered grain elevator used in Mexico, India and Southeast Asia. According to UNESCO, such design has saved millions of dollars yearly by preventing post-harvest losses.[4]

Aside from his academic activities, Mena is also a veteran rock musician, having toured since 1959 with Los Sonámbulos, Los Sinners and Tequilas. Since 1976 he is the lead singer and guitarist of Naftalinas, a band with seven albums and over a hundred live performances.[2]
