Research Interests

Dr. Jun has worked in a broad spectrum of medical fields including purification and characterization of a B-lymphocyte inducing factor (BIF) using single cell cloning of human myeloma cell line, development of DNA pattern recognition program, investigation of loci involved in progression of type 2 diabetes using Framingham Heart Study, genome-wide scans for druse formation, age-related macular degeneration, and diabetic nephropathy, and identification of causal variants in EPHA2 for age-related cortical cataract using worldwide longitudinal cohorts. She has also been involved in large genetics consortiums for diabetic nephropathy and Alzheimer’s disease. In these collaborative efforts, much of her work is engaged in study design, development of analysis plan, database development and management, and implementation of statistical methods. Her current projects encompass multidisciplinary areas of Alzheimer’s disease, age-related macular degeneration, age-related cataract, and idiopathic membranous nephropathy. The centerpiece of her future study consists of two primary focuses: investigation of shared genetic risk factors between age-related neurodegenerative diseases using bivariate framework and development of bioinformatic tools to identify shared gene-gene interactions among diseases using genome-wide sequencing data.
