Curriculum Vitae

Education

Antonio L. Sánchez holds a degree in Aeronautical Engineering (1991) from the School of Aeronautics in Madrid. As part of their 6-year education programme, he spent a year at the Department of Aeronautics of Imperial College (University of London), where he was granted an International Diploma in Aeronautical Engineering (1990).

After completing his mandatory military service as a Second Lieutenant in the Air Force Headquarters (1992), he moved to University of California San Diego, where he obtained a Master in Aerospace Engineering (1993) and a PhD in Engineering Physics (1995) in the Department of Applied Mechanics and Engineering Sciences (now the Department of Mechanical and Aerospace Engineering) under the supervision of Prof. Forman Williams. His dissertation dealt with the asymptotic description of hydrogen flames, a topic of interest at the time in connection with hypersonic propulsion applications.

As a Post-Doc (1996), he worked with Prof. Paul Clavin on detonation theory at the IRPHE (CNRS) in Marseille. Since then, he has been a faculty member at the Universidad Carlos III de Madrid, where in 2002 he was promoted to full professor of Fluid Mechanics in the Department of Thermal and Fluids Engineering.

Antonio's understanding of fluid mechanics and combustion has benefitted inmensely from the counselling of Prof. Amable Liñán, first as an undergraduate student in Madrid, then as a graduate student during Amable's summer visits to UCSD, and finally in the post-graduate period as his close collaborator in various research problems. Most of Antonio's accomplishments are a result of that fruitful 20-year collaboration.

Research Interests

Antonio’s research falls within the general field of chemically reacting flows, including research topics related to clean combustion technologies, aerospace propulsion devices, and safety hazards in the built environment. He is interested in fundamental problems that involve the interplay of fluid mechanics, transport processes, and chemical reactions, in particular those emerging in practical combustion systems. His research approach takes advantage of the disparity of the length and time scales encountered in these complex problems to simplify the solutions, often by application of asymptotic methods that help to identify simpler sub-problems and serve to extract the fundamental underlying physics. His work has covered a large number of different combustion and fluid-mechanical problems, including a wide range of reactive phenomena of technological importance such as spontaneous and forced ignition, deflagrations, detonations, diffusion flames, partially premixed combustion, and spray combustion.
