Systems Control Techonology: June 1979 - June 87.
	Applied Dynamic Programming Algorithm to Cruise-Missile path optimization. Developed closed-loop ECM techniques for various types of radars. Analyzed feasibility of a terminal-homing SAR anti-tank missile. Developed statistical models for Ballistic Missiles interception. Analyzed effect of Forward-Looking-Sensor on Cruise-Missile survivability. Analyzed miss-distance of anti-ship missiles. Developed Dynamic Programming Approach to streak detection in IR imagery.
Israel Aircraft Industries (IAI): May 1968 - September 1977.
	1975-77	Headed an engineering group tasked with designing the Tel-Aviv "Mass-Transit System". Studied and visited existing worldwide systems concentrating on Automatic Train Control/Operation/Supervision. Studied related areas of communications, displays, and man-machine interfaces. Developed simulation models for above. Prepared tentative specifications.
	1974-75	Headed an engineering group tasked with preparing specifications for a missile design project. Coordinated design, implementation, integration, and field testing. Developed simulations in order to optimize critical parameter and define performance bounds.
	1971-74	Did performance estimation, feasibility/cost-effectiveness studies on a broad spectrum of projects in areas of Electro-acoustics, Radar, and Navigation.
	1970-71	Designed control loops for a missile including guidance and homing laws and logic.
MILITARY SERVICE: June 63 - May 68.
	Served as commissioned officer in the Israeli Air-Force. Was in charge of maintenance and development of airborne and ground radars and fire-control systems. Was also responsible for automatic landing instrumentation.
