Philosophy of care | I offer you a blend clinical excellence, patient-centered care and lifetime learning. | Why I entered medicine | I have always had an analytical mind and a passion for problem-solving. Growing up in China I excelled in math, joined a gifted program and later in Canada enrolled in the International Baccalaureate program, earning multiple awards in mathematics competitions. This foundation led me to pursue biomedical engineering at one of Canada’s top undergraduate programs, where I discovered my interest in fluid mechanics and completed my thesis on carotid artery flow patterns using phase contrast MR. The experience sparked my passion for radiology and ultimately shaped my career path toward neuroradiology. | Community involvement | Active church member. | Personal interests | When relaxing I enjoy video games and piano.
