I am a Tenure-Track Associate Research Scientist with deep passion for improving health informatics with better patient diagnosis and treatment using big and multiple data sources and novel computational algorithms. I earned my PhD in Computer Science from University of Wisconsin-Milwaukee and since then, I have been on a quest to explore and solve problems that are “worth it” and make the most positive impact on people’s lives. In my current position in Biomedical Informatics Research Center at Marshfield Clinic Research Institute, I have successfully leveraged my background in computer vision, machine learning modeling, algorithm design and big data analytics to find solutions to a diverse range of problems in biomedical and health informatics. I am passionate about computational health informatics and machine intelligence.

Research Interests

3D Computer Vision, Machine Intelligence, Computational Health Informatics
