Dr. Puttlitz is president of Puttlitz Engineering Consultancy, LLC, a company he founded in 2004. Previously, he held numerous engineering positions during a 43-year career at IBM, where he was awarded an IBM Outstanding Innovation Award and the Master Inventor Award for his work on flip chips. An IEEE Fellow, he earned his bachelor’s and master’s of science degrees in metallurgical engineering and a doctorate in metallurgy / materials science engineering from Michigan State University, East Lansing, Mich.
