Our Teachers

Anna Burago

Anna (Ania) Burago, is the founder and lead teacher of  Prime Factor. She is  a software developer and a mathematician  with a long-time passion for math circles. In her classes, she combines the rich traditions of the Russian-style mathematics for gifted children with her experience of teaching extracurricular math in a US classroom.

Anna grew up in Russia, in St. Petersburg. Her passion for math dates back to her school years in Russia. Anna was an enthusiastic math circle student who grew into an enthusiastic math circle teacher.

In the US, Anna has taught math circles for the past 10 years. With a group of friends, they started the first Seattle math circle in 2002. The primary motivation was to provide their children with the benefits of math circle education. This affair resulted in organizing Northwest Academy of Sciences: a group of circles where Anna still remains a lead teacher ( The Prime Factor is a direct spin-off of Northwest Academy and is organized in order to make circles more accessible for students in the Seattle area.

Anna is a book author. Her book "A Year of a Mathematical Circle" is published by AMS (American Mathematical Society, "Mathematical Circles Library" series, 2013). The book contains a full set of materials (lessons and problem sets) for one year of  a middle-school math circle teaching.

Anna is involved in a lot of other extracurricular math activities. She is a regular speaker and participant of the MSRI (Mathematical Sciences Research Institute, Berkeley) math circle conferences. She is a visiting lecturer at SIMUW (Summer Institute of Mathematics at the University of Washington). Anna taught Math Challenge and  Math Stretch for Robinson Center for Young Scholars (UW).  She is  also a local Math Kangaroo Competition organizer.
Anna received her first degree in math from the St. Petersburg State University, Russia.  Her Master degrees in Mathematics and  Computer Science are both  from the University of Washington, Seattle.

Luba Malkina

Luba Malkina got her Masters degree in Mathematics and Statistics from Saint-Petersburg State University, Russia.

For several years, she was teaching math circles at Northwest Academy of Sciences. She had also been a coach of elementary and middle school math teams that successfully performed in various local and regional math contests.

Luba developed an online interactive elementary school math curriculum for Reasoning Mind, Inc and worked for Perfection Learning, Inc, creating the electronic math textbooks for middle and high school students. This summer, Luba taught Summer Challenge Math Topics at Robinson Center for Young Scholars at University of Washington.

Luba is a lead teacher for elementary and middle school math circles at Prime Factor.

Katerina Seniuk

Kateryna  (Katie) Seniuk  got her Master’s degree in Mathematics and Computer Science from Chernivtsi National University, Ukraine. She has been teaching math, statistics and computer science for 5 years, publishing over 30 articles in various mathematical journals. She also worked as a part of a medical research team, performing medical data analysis and processing. At the same time she always dedicated herself to working with children, engaging them in mathematical and extracurricular projects.

For the past few years, Katie has been designing and programming websites and working as a coach of elementary school math teams, which fulfills her dream of empowering children’s education. Kate joined Prime Factor in 2012. She spent a year teaching in our elementary circles. She is looking forward to another exciting year at Prime Factor.

Julia Magidson

Yuliya (Julia) Magidson received a Master’s Degree in Mathematics and a Bachelor’s Degree in Teaching from Dnepropetrovsk State University in Ukraine, and enriched her education at Oranim Academic College in Israel. Throughout her career she taught mathematics and computer programming in middle and high schools.

During the last four years in the United States, Yuliya eagerly volunteered at Pacific Cascade Middle School and Issaquah High School as an Instructor in math clubs, helping introduce students to the beauty, variety and challenges of mathematical science. Throughout this time her pupils successfully competed in numerous Washington State Math Olympiads such as Math Is Cool, MATHCOUNTS, Washington State Olympiad, Math Kangaroo, and others.

Her passions are building three-dimensional puzzles, playing mathematical games and solving interesting math problems, and today she is enthusiastic to share her knowledge and experience with young mathematicians in Prime Factor Math Circle.

Prime Factor Math Circle is a nonprofit organization. The goal of Prime Factor is to engage school children in the world of extracurricular mathematics with the purpose of developing their math knowledge, problem solving skills and creative thinking abilities. We have a lot of plans and ideas how to grow and expand. We welcome donations and we will put them to a good use.
