Dr. Sampyo Hong

Associate Professor of Physical Sciences

Division of Mathematics and Natural Sciences


  • PhD, Computational Physics, Kansas State University, 2005
  • BS, Physics, Korea University (Seoul, Korea), 1993


Dr. Hong was born in the countryside of a southern South Korean province. He has always had a desire to understand how nature works. When Dr. Hong attended high school, he moved to the city to attend a Christian mission school, founded by an American Southern Presbyterian missionary. At the time he had no interest in Christianity; however, during a schoolwide revival he received Jesus Christ as his Lord and Savior. This was a joyous and exciting time for Dr. Hong as he was grateful for the opportunity to grow spiritually while among fellow believers. After completing his military duties in South Korea, he moved to the U.S. to study Computational Physics at Kansas State University. He later worked at the University of Central Florida until he joined the BPC family in 2016.
