Profile Summary 【 Display / hide 】

  • My research interests include theories and methods in optimization, signal processing and data science, and their applications including deep learning. Our goal on the theoretical aspect is to “create innovative algorithms that can solve inverse problems in various fields” mainly via convex optimization techniques. On the application aspect, we aim to “apply cutting-edge mathematics to real-world data and introduce it into operational systems,” e.g., in the weather radar field.
