David Reznik
Founder, President & Director of R&D, Raztek

During the last decade, David has developed and refined several innovative technologies,  the latest of which has been Electroheating™. David has proven Electroheating™ to be a viable technology and he has managed the implementation of three generations of this technology since it was introduced in 1987. The first generation of Electroheating™ technology was implemented at Papetti’s Hygrade Egg Products, Inc. Today, Electroheating™ technology continues to provide breakthrough solutions for the food and biotech industries. David actively publishes articles on Raztek’s technology and has been a speaker at several recent industry events.

Five years prior to the inception of Raztek, David established and operated the Technical Research Center division of Tri Valley Growers in California, one of the world’s largest can making and food canning operations at the time. The Technical Research Center’s charter was to develop and implement new technologies for canning and can making. The Technical Research Center was eventually transformed into Raztek Corporation in 1987.

David holds a BS degree in Chemical Engineering (1960) and an MS in Food Science and Engineering (1963), both awarded by the Technion-Israel Institute of Technology (Technion is the Israeli equivalent of MIT). After his academic endeavors, David began a distinguished career in the metal packaging and food processing fields in 1967. David formed his own R&D company in Israel in 1973, and ultimately undertook the project with Tri Valley Growers in 1982.

He was also Vice President of R&D at Bayer (Miles) at their Biotechnology Group in Elkhart, Indiana, where he headed product development and led the research to produce ethanol from ground corn.

Walter earned his PhD and MS in Chemical Engineering from the University of Notre Dame, and his BS degree in Chemical Engineering from the Illinois Institute of Technology. He holds an MBA from Michigan State University.

Gad Shelef
Mechanical design

As the sole owner of Gizmonics, a mechanical consulting and design firm, Gad applies his vast experience in mechanical design to the development of industrial, consumer and aeronautics products. In this capacity, Gad provides mechanical design for Raztek's technologies. He also serves as an R&D engineer at Stanford University, Department of Aeronautics and Astronautics, Robotics Laboratory. Prior to these contributions, his distinguished leadership of engineering projects for the Ministry of Defense in Israel has earned him a special award for a breakthrough in a specific, classified design.

Gad earned his MS degree in Mechanical Engineering from Stanford in 1982, where he also served as a faculty advisor for MS students' projects and as a part-time research assistant, designing experimental systems including Flexible Arm, 4-Disk system and 2-Link Arm. Gad also designed mechanisms and structures for Britten-Norman's Islander and Trislander aircraft at the Bembridge Airport in England. He earned his Bachelor of Science in Aeronautical Engineering at the Technion - Israel Institute of Technology.
