Professor Guillermo Aguilar received his Bachelors degree in Mechanical and Electrical Engineering from the National Autonomous University of Mexico (UNAM) in 1993, and his Masters and Doctor of Philosophy degrees in Mechanical Engineering from the University of California, Santa Barbara in 1995 and 1999, respectively.

Research Topics

Dr. Aguilar's research focuses on the experimental and numerical modeling of fluid mechanics, thermodynamics, and thermal processes relevant to biomedical optics and medical laser applications. This includes the combined use of cryogen cooling and laser irradiation for the therapy of various dermatologic conditions, drug perfusion, cryosurgeries, and cartilage reshaping, among other applications. Other research interests include droplet and spray atomization dynamics for heat transfer applications as well as laser processing and optical characterization of advanced materials.
