Online learning sites are an affordable and flexible way to teach yourself the foundations and get a feel for the industry, whether you're interested in STEM or other traditionally underrepresented fields like gaming."

Though she originally intended to study computer science, she was drawn to mathematics after taking a course on complex analysis. Her other research interests lie in geometric function theory, hyperbolic geometry and the mathematics of medical imaging."
