Biography

Johnny received his BS in Bioengineering (UC Berkeley) in 2011 and MS in Bioengineering (UCLA) in 2013, after which he joined the UCLA medical imaging informatics (MIIs) group for continuing graduate study. Johnny research focuses on machine learning application in clinical data and medical images; he is passionate about the cutting-edge deep learning techniques (CNN, RNN, Autoencoders, etc) and is actively seeking opportunities to apply these techniques in various medical problems. He is working on applying deep learning techniques to identify correlated features across multiple data sources (e.g., demographics, labs, imaging, etc.), and use these features in multimodal framework to better predict stroke patients' outcome, with the hope of detecting cases that need to be treated more or less aggressively.

Before joining the MIIs group, he had been software engineer for several summer internships, working in companies/teams including Amazon.com and BuildUCLA (previous Simul8). In UCLA, Johnny has been actively involving in the committee board of Engineering Graduate Student Association (eGSA) and Chinese Christian Fellowship (CCF).
