About me
About me
I am a Postdoctoral Research Associate at EEE Department of Imperial College London (ICL), working with Prof. Ayush Bhandari on computational imaging and modulo sampling. Previously, I was a Postdoctoral fellow at EE Department at CUHK, advised by Prof. Thierry BLU. I obtained my Ph.D. degree from the Chinese University of Hong Kong where I had a wonderful time, in July 2021, supervised by Prof. Thierry BLU. I received my bachelor's degree in Electronic Engineering from Sichuan University (SCU) in 2017. My research includes sampling theory, computational imaging, and image & signal processing, with a special interest in non-conventional geometric visualization of 1D real data. I am fortune to cooperate with Prof. Christopher Gilliam and Prof. Jizhou Li. I was awarded CUHK EE Department's 2021 Postgraduate Student Research Excellence Awards.
