Dr. Brian Leslie


Brian was born, and brought up, in the Highlands of Scotland.  He went to school in the University of Aberdeen, Scotland, where he earned a first in Natural Philosophy, an MS in Instrumentation, and a PhD in Physics . He came to the USA as a post-doc at Stanford sponsored by the European Space Agency, planning to stay for only a couple of years, but forgot to go back.

His first career was in research and Engineering management in Silicon Valley, initially at HP labs and subsequently at KLA-Tencor developing the world’s leading semiconductor defect detection equipment. On retiring , the Leslies moved to Orange County for family reasons, and Brian started a second career in teaching his passions of physics, engineering and robotics at Tustin High school.

Brian is married to Jaya, a fellow science teacher. They have two grown-up kids: Jhansi, who is starting a post-doc in microbiology at UVA; and Neel, an applications engineer in the Bay Area. Last but not least, there is Molly, a very special, border collie/Alsatian who runs the show.
