I am a professor in the Division of Big Data Science at Korea University Sejong Campus in South Korea. Additionally, I serve as an adjunct professor in the Department of Biostatistics at the College of Public Health at OSU.  I am deeply committed to advancing research in statistical modeling and mathematical biology, primarily focusing on developing statistical models for epidemics and biological systems. My work includes developing various mathematical models for biological systems that incorporate stochastic processes using Bayesian approaches. Another area of my research involves big data analysis, which entails multivariate and categorical data analysis. I also address critical issues in data integrity by researching methods for missing data imputation, ensuring that analyses remain robust despite the presence of incomplete datasets.  My goal is to contribute not just to theoretical advancements, but also to practical applications in fields such as epidemiology, genomics, and social sciences, ultimately helping to solve real-world problems through innovative statistical approaches.
