Hi, Im Eric R

I’m Dr. Eric R., a mathematician with a Ph.D. in applied mathematics. My expertise lies in numerical analysis, nonlinear optimization, and stochastic methods. I’ve worked in interdisciplinary R&D, collaborating with engineers and computer scientists to solve complex mathematical problems, including integrated circuit design.  

 I’ve also taught upper-division mathematics and computer programming as an adjunct professor at UCLA. With over a decade of experience in C++, Matlab, and Python, I enjoy tackling challenging problems. I created Fraction Guru to make fractions easy to understand, providing clear explanations and resources to help students and educators master this essential mathematical concept.
