Email: wlittlefield@losmedanos.edu

Computer Science Instructor, Adjunct

After getting a BS at MIT and a Masters at Stanford, Mac worked at Washington University on the LINC evaluation project and the Macromodular Project. He joined the Peace Corps in Ecuador teaching Electrical Engineering. Mac received his doctorate at Washington Univ., and then began a spiritual odyssey culminating in meeting Baba Muktananda in 1975. When Baba passed on in 1982, Gurumayi, Baba's successor, became his teacher. From 1975 onward, Mac says his life had taken a totally different trajectory than he ever could have anticipated. He considers himself a very fortunate person.

Mac taught Computer Science at Sullivan County Community College from 1983 until 1998, and Electrical Engineering at State University of New York in New Paltz in 1984 and 1985.  In 1997 he received the Chancellor’s Award for Excellence in Teaching from State University of New York.
