Alfonso Ortega, Ph.D.

Alfonso Ortega, Ph.D.
Associate Vice President for Research and Graduate Programs;
James R. Birle Professor of Energy Technology in the Department of Mechanical Engineering, Villanova University

Area of Expertise:

  • Electronics Cooling
  • Experimental Methods in Thermal Sciences
  • Energy Technology
  • Nano-Engineering


Dr. Ortega is in the vanguard of researchers seeking to solve the increasingly complex problem of cooling electronics that are integral to daily life, such as laptop computers and cell phones. His specialization in heat transfer and the thermal sciences also addresses gas turbine cooling, which relates to the survivability of airplane engines. Ortega's research leads to products that perform more efficiently and last longer.

About Villanova

Since 1842, Villanova University’s Augustinian Catholic intellectual tradition has been the cornerstone of an academic community in which students learn to think critically, act compassionately and succeed while serving others. There are more than 10,000 undergraduate, graduate and law students in the University's six colleges – the College of Liberal Arts and Sciences, the Villanova School of Business, the College of Engineering, the College of Nursing, the College of Professional Studies and the Villanova University Charles Widger School of Law. As students grow intellectually, Villanova prepares them to become ethical leaders who create positive change everywhere life takes them.
