Ching-Hua Lee
Samsung Research AI Center - Mountain View

My name is Ching-Hua Lee and I work on a number of subjects in machine learning and signal processing.
- I currently serve as a Staff Machine Learning Research Engineer at Samsung Research AI Center - Mountain View.
- I completed my Ph.D. in Electrical and Computer Engineering at UC San Diego in 2020 under the supervision of Prof. Bhaskar D. Rao, an Ericsson Endowed Chair and Distinguished Professor, and Dr. Harinath Garudadri.
- I received my B.S. degree from the Department of Electrical Engineering at National Taiwan University in 2013.
My current research focuses on efficient deep learning-based solutions for speech and audio applications, including Single/Multi-Channel Speech Enhancement, Voice Commands, Speech Recognition/Translation and Speech-LLMs. During my Ph.D. at UC San Diego, I worked on adaptive filtering and sparse signal processing with applications to speech and audio.
