Dr. Jun has conducted research at NASA and served as a research professor and taught at Seoul National University (SNU). After completing a bachelor’s degree in astronomy from SNU, he earned his doctorate from SNU in 2014 with a dissertation titled “Life of the Most Massive Black Holes.” He is a prolific researcher and author, published in the Astrophysical Journal, Astronomy & Astrophysics, Monthly Notices of the Royal Astronomical Society, Journal of the Korean Astronomical Society, Publications of the Astronomical Society of Japan, Nature, and Science. He co-authored Summa Cum Laude Earth Science 1, a high school reference textbook.
Dr. Jun is a frequent presenter at meetings of the American Astronomical Society and the Korean Astronomical Society. He was also the recipient of several fellowships and awards totaling $1.3 million, including a Sejong Science Fellowship, a Korean Presidential Postdoctoral Fellowship, and a NASA Postdoctoral Program.
A member of both the Korean Astronomical Society and the American Astronomical Society, Dr. Jun is dedicated to helping students become critical thinkers through classroom and research activities and sharing with them the complementary roles of faith and science.
PHY112 - General Physics II
(4 credits) This is the second in a two-course algebra-based sequence. Topics include electricity, magnetism, electromagnetic waves, electromagnetism, and optics. Prerequisite: successful completion of PHY111SN with a grade of C- or better, or consent of department chair. Note: There is a laboratory component to this course.
PHY112L - General Physics II Lab
PHY150 - Introduction to Astronomy
(3 credits; alternate years, consult department) This course covers several topics in the field of astronomy chosen from our solar system, stellar lifecycle, astronomical observations and measurements, and a basic introduction to cosmology and relativity. The basic tools, concepts, physics, and mathematical models in astronomy are discussed. Students are expected to be able to articulate a Christian perspective of our place in the universe. Prerequisites: C- or higher in MAT109QR or MAT127, ACT math score of 22 (SAT 520) or above, or permission of instructor. Note: There is no laboratory component to this course, and it does not count as an option under Science and the Natural World. However, the course does count toward the Elementary and Secondary Endorsements in Basic Science.
PHY160SN - Astronomy
(4 credits) (NWCore option under Science and the Natural World) This course covers several topics in the field of astronomy chosen from our solar system, stellar lifecycle, astronomical observations and measurements, and a basic introduction to cosmology and relativity. The basic tools, concepts, physics, and mathematical models in astronomy are discussed. Students are expected to be able to articulate a Christian perspective on our place in the universe. Prerequisite: C- or higher in either MAT109QR or MAT127, or ACT math score of 22 or above (SAT 550 or above) or permission of instructor. Note: There is a laboratory/observation component to this course.
PHY160SNL - Astronomy Lab
PHY212 - Classical Physics II
(4 credits) This is the second in a two-course calculus-based sequence. Topics include electricity, magnetism, electromagnetic waves, electromagnetism, and optics. Prerequisite: successful completion of PHY211SN with a grade of C- or better. Note: There is a laboratory component to this course.
