Overview of research interests
Dr. Kim’s research program focuses on genetic and metabolic regulation of heart development, function and disease, with emphasis on obesity, diabetes and heart failure. First, we are interested in the molecular function and mechanism of Iroquois (Irx) transcription factors in the heart, which are not only implicated in organ development, but also in energy homeostasis regulation. Second, we are investigating metabolism of the heart and its communications with other core metabolic tissues/organs (e.g. adipose tissue and liver). Using genetically engineered mice as our principal models, we integrate physiology with molecular and systems biology approaches to address the fundamental questions in heart function and diseases.
