I am a Ph.D. student in the Department of Electrical Engineering, Columbia University, studying under the supervision of Prof. Xiaofan Jiang and Prof. Matthias Preindl. I received my Master of Science degree (Honor Student) in Electrical Engineering from Columbia University (2018), and the Bachelor of Science degree (Magna cum Laude with High Honors) in Engineering Science from Smith Collge (2017).

My research lies at the intersection of artificial intelligence, machine learning, cyber-physical systems, and data analytics. I am focusing on designing the next generation of human-centric intelligent wearable devices and Internet of Things platforms to improve our lives by sensing the physical world in its many forms.
