David Patrick, Director

David Brown

David Brown received his Bachelorís degree in mathematics and physics from Bucknell University and his Ph.D. in theoretical physics from the University of Rochester. Following a career as a research scientist at UCSD, he became involved with the San Diego Math Circle and soon became its Director.  At SDMC, David is involved with talented students in the fifth through twelfth grades and is especially concerned with feeding the vigorous intellectual appetites of todayís highly-motivated students.  SDMC has grown substantially and the swelling achievements of its students have contributed to San Diegoís growing visibility as a center of excellence in math and science.  David sees SDMTC as an opportunity to share the benefits of math circle experiences with middle school teachers, who play a crucial role in the development of young peoplesí attitudes, abilities, and achievements.

Yana Mohanty

Yana is a native of Odessa, Ukraine. She immigrated to the United States in 1979. After graduating from UCLA with a Bachelor of Science in Electrical Engineering, she worked at Hughes Aircraft, and subsequently earned her Masters Degree in Electrical Engineering from the University of Massachusetts at Amherst. Yana earned her Ph.D in Mathematics at UCSD in 2002. Since then taught mathematics for 5 years at UCSD, and for a year at Palomar college.

Yana enjoys bringing the perspective gained from her varied career and exposure to different cultures into the classroom. She is one of the instructors for the San Diego Math Circle, and she currently designs math educational tools.

Cynthia has taught at LaPresa Middle School in Spring Valley, CA since 2000.  Previous to her teaching career she was a Financial Analyst with Prudential Insurance in Newark, New Jersey and the controller of a large construction company in Northern NJ.  She has a BS in Accounting, Law and Taxation with a minor in Mathematics, and she received her MA from Point Loma Nazarene University.  

Cynthia has always wanted an avenue where middle school teachers could collaborate and do problem solving together in a relaxed atmosphere.  When she was approached about starting a Teachers Circle in San Diego County, she was, without hesitation, willing to help form this chapter.  She welcomes other middle school teachers to enjoy the time with colleagues and be able to bring problem solving techniques back into the classroom.
