Hong Liu

Hong Liu was awarded a Ph.D. in Mathematics and an M.S. in Computer Science from the University of Arkansas, Fayetteville in 2000. Since then, he has ascended the academic ranks from Assistant to Full Professor, specializing in Mathematics and Computing. In 2019, he pioneered the Master of Science in Data Science program and serves as a professor in Data Science. He serviced on the National Selection Committee for the prestigious Presidential Awards for Excellence in Science, Mathematics, and Engineering Mentoring (PAESMEM) in recently years, and the NSF panels in Education and Human Resources (EHR) and Computer and Information Science and Engineering (CISE). His exceptional service was honored with the President and Board of Trustee’s Special Service Award at ERAU in 2014.

Dr. Liu is an interdisciplinary scholar with an extensive publication record, having authored 42 peer-reviewed articles across a variety of disciplines including partial differential equations, model-checking, robotics, data science, and STEM education. As a lead investigator and collaborator, Dr. Liu has contributed significantly to 15 sponsored research projects, successfully securing over $3 million in funding from prestigious bodies such as the NSF, the US Air Force, and the DOE, with him directly overseeing approximately $2 million.

At present, Dr. Liu is spearheading a pioneering collaborative effort involving 11 universities, which focuses on advancing adaptive distributed learning technologies, automating learning assessments, and enhancing data science workforce development. Furthermore, in partnership with peers at New Mexico State University and the University of Maryland at Baltimore County, Dr. Liu is applying AI and ontological frameworks to enhance data accessibility within the aviation and space industries.
