I am a retired engineer (materials science/ semiconductors), math teacher, and Technical Interpreter for NASA My teaching experience includes math (most recently, Algebra II), Chemistry, physics, Russian Language and Lit. As a process engineer, I have trained and supervised technicians and other engineers in the art of Silicon chip manufacturing and worked with other materials, such as ceramics and diamonds. My duties as an instructor were to make sure that they knew enough theory and practice to the point they could be trusted to work independently with very costly materials and equipment. For a few years I taught a number of Russian language students who successfully passed exams at the Slavic Department of the UCLA. Since 1994, I worked for NASA International Space Station (meetings, contract negotiations, on-board software, safety, life support, etc., etc.)
