Pam Liu STEM Principal Teacher

Pam holds a Master's Degree in Education from Harvard University and a Bachelor's Degree in Mathematics from Duke University. She has taught at schools in Durham, NC; Shanghai, China; and Atlanta, GA. Her favorite subject to teach is math - which ironically stems from the fact that math used to be her biggest academic fear! Conquering mathematics is what Pam believes gave her the skills to leverage for many significant opportunities. These experiences include computer coding in healthcare technology, novel research in public health (leading to her first journal publication, cited in a policy draft for the Ministry of Health in India), design and implementation of leadership workshops, and completion of three engineering internships with NASA (she is a space geek!). Recognizing the powerful role of math as a gatekeeper in society, Pam makes dispelling math anxiety a top priority in her teaching endeavors. In addition to improving math literacy, Pam is passionate about shifting the status quo on issues of social justice and healthy living. Her social media pages offer daily inspiration to living a life of passion, purpose, and positivity (Instagram and Facebook: @inspirationbypam). When she needs fresh perspective, Pam loves to travel to experience new cultures and meet new people.
