Simon Rubinstein-Salzedo is the founder and main teacher at Euler Circle. Simon received his PhD at Stanford University in 2012 under the direction of Akshay Venkatesh in algebraic number theory. He has done research in many areas of mathematics, including number theory, algebraic geometry, combinatorics, game theory, probability, and complex analysis. Before founding Euler Circle, Simon taught mathematics at Stanford University and Dartmouth College.
In addition to his teaching at universities, Simon has been teaching mathematics to advanced middle-school and high-school students for over a decade and is extremely popular among his students. He is currently the lecturer for Program II at the Stanford University Mathematics Camp (SUMaC), where he teaches algebraic topology. He has worked at The Art of Problem Solving and has taught at many math events and run many math circles in the Bay Area. He is also the coach of the San Francisco Bay Area ARML team, which won the national championship for three consecutive years. His greatest claim to fame in life is probably having a factoring trick named after him.
Simon has also successfully directed mathematics research projects for high-school students, leading to five original papers coauthored with students so far, and more projects are currently in progress. His papers can be found on his website. Please contact him at email@example.com.
Outside of mathematics, Simon is also an avid musician, chess player, and calligrapher.
