Research & Clinical Interests
Research Interests: 

Dr. Chanprasert is interested in doing clinical research to characterize adult-onset metabolic conditions to lead to the way of effective treatment. In addition, he is interested in therapeutic trials of mitochondrial diseases.

Clinical Interests: 

Dr. Chanprasert is interested in adult-onset metabolic and mitochondrial diseases which were once thought to be diseases of children. He is also interested in establishing transitional care of patients with genetic conditions who are growing into adulthood.
