He Sun 孙赫

I am a postdoctoral researcher and Amazon AI4Science Fellow at Caltech CMS, working with Prof. Katie Bouman. My research focuses on computational imaging and adaptive optics, where multidisciplinary ideas, including optics, control, signal processing and machine learning, are applied. I also have strong interests and industry experiences in robotics.

I received my PhD in Mechanical and Aerospace Engineering from Princeton in 2019, advised by Prof. N. Jeremy Kasdin. My PhD thesis is about space telescope's adaptive optics system for high-contrast exoplanet imaging. I previously received my B.Eng. degree in Engineering Mechanics and B.A. degree in Economics from Peking University in 2014.

I am on the academic job market.

Featured Projects
Computational Imaging
Computational imaging tightly integrates computational inference as part of the imaging systems to recover hidden signals from non-ideal measurements. My computational imaging research spans imaging hardware-software co-design, deep learning inference algorithms, and uncertainty quantification. Most of these projects have contributed to the Event Horizon Telescope (EHT) for black hole imaging.
Adaptive Optics (AO)
Adaptive optics (AO), is a control system that removes the wavefront aberrations in telescope systems. It is very important in the large ground-based telescopes and the next-generation space telescopes (e.g. RST, Habex, LUVOIR) in order to achieve a high contrast for Earth-like exoplanets imaging. I work on the control algorithms and the spectrograph for space telescope AO.
