News: I have been named as a Highly Chied Researcher in the Clarivate's 2023 list.

My research has been focused primarily on two areas:

  • developing novel computational diffractive imaging techniques (ptychography, 4D STEM) for cryogenic electron microscopy (Cryo-EM), light atomic detecting (O, Li elements), low dose imaging (beam sensitive materials), 3D reconstruction and EM field mapping, which can then tackle characterization challenges across the physical and life sciences, ranging from battery materials to biological macromolecules;
  • in situ examining atomic structures of advanced materials and their functional properties with an emphasis on complex oxides and two-dimensional materials.
To date, I have published over 100 refereed journal articles, including Nature, Science, PNAS, Nature Nanotechnology, Nature Electronics, Nature Catalysis, Nature Communications, Physical Review Letters, Advanced Materials and Ultramicroscopy.Related Websites:

Big-data in Super-resolution Microscopy

Super-resolution microscopy

Ptychography is an emerging computational microscopy technique for acquiring images with resolution beyond the limits imposed by lenses, which has been applied to high resolution x-ray imaging in synchrotron facilities and accurate wavefront-sensing in space telescopes. Rather than looking at something big or far-away, we are aiming for visualizing the basic building blocks (such as proteins) of all life in three dimensions towards near-atomic resolution by developing ptychography on world-leading cryogenic electron microscopes (Nobel Prize winning technique), further enhanced by artificial intelligence and machine learning.

Dynamic Field Mapping in Quantum Materials & Devices

Ferroic

 Direct visualisation of ferroic orderings (ferromagnetism) in materials at the atomically thin limit [1] is exciting not only from a fundamental physics perspective but is also critical for the characteristics of ferroelectric and ferromagnetic materials used in applications that include information storage and logic technologies. Quantitative information about field distribution with a high spatial resolution towards an atomic scale is indispensable for a complete understanding of the underlying physics behind the ferroic phenomena.

In-situ Characterization for Nano-devices

In situ

Combined with state-of-the-art ultrafast detectors, the development of innovative nanoscale device testing systems can provide an advanced in-situ experimental capability in aberration-corrected TEM. This integration has great potential for directly visualizing the atomic-scale evolution of structures in nanodevices during continuous external stimuli on sub-millisecond timescales.

Low-dose Imaging for Green and Energy Materials

Solarcell

Materials for clean and sustainable energy, like zeolites, MOFs, lithium batteries, and solar cells, frequently feature light elements that produce faint signals in electron microscopy and can quickly deteriorate under an electron beam. The swift progress in low-dose 4D STEM ptychography at cryogenic temperature has opened up an unparalleled opportunity to investigate the atomic-scale structure of these materials
