UCLA Olga Radko Endowed Math Circle

Founding Director

Olga Radko was the Founding Director of the LAMC (now called the UCLA Olga Radko Endowed Math Circle in her honor). Olga received her Ph.D. in mathematics from UC Berkeley in 2002 specializing in Poisson Geometry, and worked in the UCLA department of Mathematics ever since. Olga started LAMC in 2007 and led it until her death in 2020.  Please see the In Memoriam page for more information about Olga.

Mario Bonk
Mario Bonk received his academic education in Germany. He  came to UCLA in 2010.  His research  lies at the interface of geometry and analysis and often relies on an extension of classical results to a non-smooth or fractal setting. He was an invited ICM speaker in 2006 and currently serves as  the Chair of the Department of  Mathematics.
Professor Jane P. Chang
Jane Chang
Jane Chang received her PhD in Chemical Engineering from MIT and has been a faculty member in the UCLA Samueli School of Engineering since 1999.   Her research focuses on the synthesis and chemical processing of novel and multifunctional materials.  She received the Career Award from NSF (2000), the Young Investigator Award from ONR (2003), the AVS Peter Mark Award (2005), the AVS Plasma Prize (2018), the TRW Excellence in Teaching Award (2002), the Professor of the Year Award from her department (2003, 2004, 2009) and holds the William F. Seyer Chair in Materials Electrochemistry.
Sierra Chen
Sierra Chen obtained her M.A. in Mathematics from UCLA in 1993.   She is an entrepreneur in the field of international trade, a leisure artist, an enthusiastic world traveler, and a hopeless optimist.  For over two decades, promoting educational excellence has been one of her passions.  She taught math classes at community colleges as a part-timer from 1997-2004.   While developing her businesses across the continents, she enjoys mentoring students who are eager to learn and thrive.  
Oleg Gleizer
Oleg Gleizer is the Chief Curriculum Developer at the LAMC.  He received his Ph.D. in Mathematics in 2001 from Northeastern University of Boston specializing in representation theory and special functions. Oleg sees his mission in inventing ways to present some important parts of modern day Mathematics (and occasionally Physics), typically reserved to college, to the children from age four and up. 
Dan Hoff
Dan Hoff is the Curriculum and Instructional Supervisor for the circle's advanced groups. He received his PhD in Mathematics from UC San Diego in 2016 and now researches and teaches as a postdoc in the UCLA Department of Mathematics, where his primary research is in functional analysis, with a focus on operator algebras and their connections to fields such as ergodic theory and measured group theory. He has been working with the math circle since 2017, when he first had the opportunity to be amazed by its students and program.
Doug Lichtman
Doug Lichtman is a Professor of Law at UCLA and has been active in Math Circle for over a decade, first as a father and now as a volunteer instructor.  In addition to his work with Math Circle, Doug has coached middle school debate, taught advanced fifth grade math, and is now working with his oldest son to run and expand a weekly Math-Circle-inspired computer coding community for kids, hosted at www.ComeCodeWithUs.com.  
Vivian Moy-Dinson
Vivian Moy-Dinson has taught K-5 for the past 17 years and is a Learning Specialist in the Covina Valley Unified School District.  She received her Masters with honors in Education from Azusa Pacific University and her Undergrad in Liberal Studies from Cal Poly Pomona University.  Vivian joined the LAMC in 2017 and found it so rewarding to see the very young get excited about math in her Breaking Numbers Into Parts (BNP) course. She is a firm believer that all children can learn when given the opportunity and strives each day to challenge and enrich their minds.

Dima Shlyakhtenko
Dima Shlyakhtenko received his PhD in mathematics from UC Berkeley and has been a member of the UCLA mathematics department since 1998.  His primary research area is in functional analysis.  He was an invited speaker at the 2010 ICM and received multiple awards, including an NSF graduate and postdoctoral fellowship, a Sloan Fellowship and a Clay Math Institute Special Prize.  He currently serves as the director of UCLA's Institute for Pure and Applied Mathematics.
Terence Tao


Terence Tao (chair) was born in Adelaide, Australia in 1975. He has been a professor of mathematics at UCLA since 1999.  Tao's areas of research include harmonic analysis, PDE, combinatorics, and number theory.  He has received a number of awards, including the Fields Medal in 2006, the MacArthur Fellowship in 2007, the Waterman Award in 2008, and the Breakthrough Prize in Mathematics in 2015.  Terence Tao also currently holds the James and Carol Collins chair in mathematics at UCLA, and is a Fellow of the Royal Society, the Australian Academy of Sciences (Corresponding Member), the National Academy of Sciences (Foreign member), and the American Academy of Arts and Sciences.
Eugene Volokh
Eugene Volokh is Gary T. Schwartz Professor of Law at UCLA School of Law; back in the day, he also got a BS in Math / Computer Science from UCLA ('83), and worked for 12 years as a computer programmer.  Lawyers therefore view him as unusually good at math; mathematicians view him as a lawyer.
