Javier Gazzarri received a Bachelor’s degree in Mechanical Engineering from the University of Buenos Aires, at Buenos Aires, Argentina in 1997. His Honors project presented a method for the mitigation of flow-induced vibrations in U-shaped pipes used on heat exchangers, conducted at the National Atomic Energy Commission (CNEA).
He completed his M.A.Sc. in 2003 under the supervision of Dr. Gary Schajer. His thesis work comprised the development of a multi-sensor surface scanning system capable of measuring the profile of a moving object. The rigid-body-motion of the scanned body is removed from the acquired signal using redundant data and an algorithm based on Linear Inverse Theory. This method is particularly suitable for quality control in the lumber industry, where early identification of cutting defects is desirable due to the high cost of wood as a raw material. This work resulted in the publication of three journal papers and one US patent:
- J. Gazzarri and G. Schajer, Lumber Surface Profiling Independent of Bulk Motion. Holz als Roh- und Werkstoff (63) 347-352 (2005)

In November 2007, Javier completed his Ph.D. degree under the supervision of Dr. Olivera Kesler, now at the University of Toronto. His doctoral thesis presented the numerical model of a method to diagnose failure modes in solid oxide fuel cells using electrochemical impedance spectroscopy, in a minimally invasive way. This project is described in:

Javier’s current duties as a Research Associate at NRC-IFCI involve the numerical modeling of polymer electrolyte and solid-oxide fuel cells.
Javier worked for one year as research assistant at the National Atomic Energy Commission since 1996.
Then, from 1997 to 1998, he worked as Maintenance Engineer at TenarisSiderca, the world leader in steel pipe manufacturing at Campana, Argentina.
From 1998 to 2001, he joined Tenaris’ Research Centre as Research Engineer in the Department of Materials and Corrosion, where he was responsible for the performance of thermo-mechanical tests in steel.
Javier is a strong believer in the importance of education, and he is actively involved in teaching activities since 1994. His teaching interests include Mathematics, Mechanics of Materials, Computational Mechanics, Numerical Modeling, and Fuel Cells.
Javier’s other passions include photography, Beethoven, and Bach.
