Born in Mauritania from Senegalese parents, Mohamedou Thiam completed his undergraduate studies at Institut Supérieur Scientific (now part of the University of Nouakchott), receiving a Bachelor's degree in chemistry. He then left Mauritania to pursue graduate studies at Université Pierre et Marie Curie in France, earning a PhD in chemistry in 1998.
After post-doctoral work at the University of Massachusetts Amherst and the University of New Hampshire, Dr. Thiam joined the faculty of Saint Thomas Aquinas High School, New Hampshire in 2001. From there, he went on to hold teaching positions at Lake Forest Academy and Phillips Exeter Academy. In addition to teaching science courses, Dr. Thiam was a dorm parent and soccer coach at both schools.
During those teaching years, he returned to school and obtained a Master's degree in education (Curriculum and Instruction) from National-Louis University in Chicago.
In 2010, Dr. Thiam took on the post of director of academics and acting principal at Al-Noor Academy, the first accredited Islamic high school in New England. He joined King's Academy in 2011 as a faculty member in the Department of Physical and Life Sciences.
