My areas of interest include solid mechanics, dynamics, mechanical vibrations, and the finite element method. I teach undergraduate and graduate level courses in these subjects at CSULA. My department offers programs towards Bachelor of Science degrees and Master of Science degrees in Mechanical Engineering.
I hold memberships in the following three professional and two honor societies:
- AIAA (the American Institute of Aeronautics and Astronautics),
- ASEE (the American Society for Engineering Education),
- ASME (The American Society of Mechanical Engineers),
- Pi Tau Sigma (The Mechanical Engineering Honor Society),
- Tau Beta Pi (The National Engineering Honor Society). I was initiated by the California Epsilon Chapter.
I was a member of the CSULA teams that designed, analyzed, built, tested, and raced three solar-cell powered cars:
The first Solar Eagle car was on display at the Petersen Automotive Museum until 1997. The Solar Eagle II car is on display at the California Science Center.
- the Solar Eagle car, in GM Sunrayce USA (1990) from Florida to Michigan,
- the Solar Eagle II car, in Sunrayce 93 from Texas to Minnesota,
- the Solar Eagle III car, in Sunrayce 97 (June 19-28, '97) from Indiana to Colorado.
The Solar Eagle III car finished in first place in Sunrayce 97!
The Solar Eagle III car driven by Roman Vasquez crosses the finish line in Colorado Springs followed by our "chase" vehicle in which I am riding with the "strategy" group of our team.
The Solar Eagle III car was among the 1998 First Editions of Hot Wheels by Mattel. 
I worked on the structural analysis of the Solar Eagle III car. I have also been involved in weather and insolation forecasting for all three Solar Eagle projects.
The Sunrayce series of solar car races is no more. However, a new series of solar car races has come on the scene, the American Solar Challenge. The first race took place in July 2001, and the second race in July 2003. Both were a 2300 mile race from Chicago to a suburb of L.A., Claremont, CA. I went to see the finish of both races. A colleague of mine, Prof. Emeritus Richard Roberto, has been serving as a race official.
Since February 2004, my wife Diana and I have been monitoring with great interest, and satisfaction, the fuel consumption rate of my wife's 2004 Toyota Prius. We calculate the miles traveled per U.S. gallon of gasoline consumed (MPG), after each fill-up, and we plot the cumulative average of these MPG ratios against total miles driven. For sports, I like to hike, run, snow ski, and windsurf.
I was born in Budapest, Hungary. I was raised and attended school in Munich, Germany, Buenos Aires, Argentina, Toronto, Canada, and Los Angeles. As my family moved from one country and language to the next, my first name changed, through translation, from "István," to "Stefan," to "Esteban," to the present "Stephen," or "Steve" for short. My last name is pronounced "fel-se-gie." When it is pronounced in Hungarian, the stress is on the first syllable, but, in English, I put the stress on the second syllable. Hungary celebrated in 1996 its millecentenary (896-1996).
When I attended U. C. Berkeley, I lived for several years in I-House (International House).
My primary goal is to teach the subjects in my areas of interest from the viewpoint of what knowledge a potential engineering employer might expect from a new engineering graduate. Before I began teaching full time, I worked as a mechanical engineer for the Garrett Corporation (now Honeywell/Aerospace), where I analyzed and designed heat exchangers for aerospace applications, and the Hughes Aircraft Company (now merged with Raytheon), where I analyzed and designed tactical missile structures.
I began my teaching career as a part-time lecturer at the Univ. of Southern California where I taught for several years an undergraduate level dynamics course. Following this, and before coming to CSULA in 1979, I was a full-time lecturer at U. C. Santa Barbara where I taught for one year various undergraduate and graduate level courses in mechanics and engineering mathematics.
Included among my current research interests is the application of probabilistic methods to the design of mechanical components. These methods predict the probability of survival of a mechanical component under service loads.
