Ana Popesco, Instructor

Ana grew up in a household where excelling at math was a priority, and had to do one hour of advanced math with her father every day after school. Throughout the years she developed a passion for math and went on to graduate from Stony Brook University with a Bachelor of Science degree in Applied Mathematics and Statistics. She aspires to become an actuary, specializing in data analytics for insurance companies. Math teaches some of the most valuable skills, such as critical thinking and creative problem solving, which can be applied through all avenues of life.
