# Instructor Biography

Michelle Samuel, Assistant Professor of Psychology

Background:

-Assistant Professor of Psychology at a small liberal arts university in Los Angeles since 2009

-Voted Best Instructor of the Year (2013) by my students

-Teach: statistics, research methods, psychology and money course for a Psychology department

-Scholarship: the art and science of college level teaching

Philosophy:

I believe everyone can benefit from understanding how to solve complex problems and can do so without having to pay for a professional tutor. I was born into a family of teachers and I've tutored students since my high school days. I enjoy helping people learn concepts that are initially hard for them by breaking down big ideas into smaller easy to understand ideas. I understand that students today have many pressures on their time so I've designed my courses to quickly help you understand a concept.
