Greetings! I'm Joonha Chang from South Korea 🇰🇷, an Assistant Professor at the Louisiana State University Health Science Center, School of Public Health, Department of Biostatistics and Data Science. 

I completed Ph.D. in Biostatistics at the University of Texas Health Science Center at Houston, School of Public Health, where I had the honor of being mentored by my "academic father" Dr. Wenyaw Chan from Taiwan 🇹🇼. Prior to that, I obtained my B.S. and M.S.E. in Applied Mathematics from Johns Hopkins University. 

While I've engaged in applied research involving modeling, my passion lies in the methodological aspects of mathematics that can directly impact the real world. My research focuses on longitudinal modeling (non-homogeneous continuous-time Markov chains), latent classification, and optimization (integer programming, nonlinear optimization) algorithms. I'm particularly interested in exploring how these methodologies can be applied to advance medical and healthcare researches.
