Areas of Expertise


Bob Schiffmann has been actively working with microwave heating for over 50 years. His initial activities involved the development of a number of industrial microwave processes that were installed in the USA, Europe and Japan. This work continues to the present time in both food and non-food applications in many industries including medical, pharmaceutical, aerospace, chemical, textiles and more. As the consumer microwave oven became popular much of Bob's work was directed into this area. This includes the development of numerous consumer microwavable products including foods, packaging and cookware. He has also done many performance tests on these microwavable products for many companies.

He is an inventor of 28 US Patents, all but two of which are microwave related. The other two concern the preservation of fruits and vegetables.
