Born in the U.S.S.R. to Holocaust survivors, Nachman Kataczinsky grew up in Israel. He earned a degree in mechanical engineering from the prestigious Technion University and was an officer with the Israel Defense Forces. His employer put him on the design team for the Merkava, Israel's first tank, and promoted Nachman to head Research and Development, where he worked on ballistic armor and weapons systems for both Israel and other countries. In 1987 Nachman moved to the U.S., obtaining citizenship through a program for internationally recognized unique expertise. He is fluent in five languages and enjoys reading history and fiction in all of them, especially if the subject is mid-twentieth century Europe. His research in ballistics, which earned him a Ph.D. from California Coast University, is expressed these days mostly by shooting hand guns at paper. He dabbles in web design and programming, avidly follows political and military activities, and is happily married. The Shield is his first novel. He's working on a sequel.
