My work broadly focuses on understanding and preventing sudden cardiac death by investigating its underlying mechanisms. I aim to explore the connections between this condition and other cardiac diseases, such as coronary artery disease and heart failure, as well as non-cardiac conditions, such as chronic kidney disease, fatty liver disease, and diabetes. My approach is rooted in clinical research, with much of my work being community-based. I also conduct studies examining the burden of cardiovascular and cerebrovascular diseases on a global scale, with a particular focus on Asia and the USA. Additionally, I investigate the mechanisms behind coronary blood flow abnormalities, aiming to predict and understand lesions in heart vessels. My work seeks to improve diagnostic precision and therapeutic interventions. Beyond cardiology, I conduct studies on nephrology-related conditions, including chronic kidney disease, nephrotic syndrome, and pyelonephritis. My research in this area is centered on better understanding disease mechanisms and optimizing treatment strategies. Finally, I am deeply interested in acute critical care, particularly in the context of cardiovascular and cerebrovascular diseases. My work includes investigating and reporting case studies and conducting clinical research to advance care for patients in critical conditions.
