Slobodan's parents are Milojko and Julijana Ćuk.[3] He is bilingual, American English and Serbian.[1] On February 29, 1972, Slobodan immigrated from Belgrade, Yugoslavia to United States and was sponsored by NASA.[2]

Slobodan received a Dipl.Ing. from University of Belgrade in 1970, a M.S. in Electrical Engineering from Santa Clara University in 1974; and a Ph.D. in Power Electronics from the California Institute of Technology (Caltech) in 1977.[4][1][2]

Professional life

For over 20 years, he was a full-time Professor of Electrical Engineering at the California Institute of Technology until January 1, 2000.[5]

In 1979, Slobodan founded TESLAco, which is currently located in Laguna Niguel, California.[1][6] It had a charter to apply basic research results developed at Caltech for practical commercial and military designs.[5]

Over 30 patents have Slobodan Ćuk's name on them.
