Dr. He Cheng is a Professor at the Institute of High Energy Physics, Chinese Academy of Sciences. His research integrates neutron/X‑ray scattering techniques with soft matter physics to probe multiphase, multiscale structures and dynamic mechanisms in polymers, colloids, gels, and biomaterials. He pioneers advanced scattering instrumentation: he designed and built the world’s first multi‑slit VSANS instrument at China Spallation Neutron Source, with world‑leading collimation technology, and contributed to China’s first SANS instrument. He develops novel data analysis methods for 3D atomic‑resolution structure reconstruction of disordered materials. He has published >90 SCI papers and authored book chapters. He holds multiple patents and software copyrights, serves as associate editor for several journals, and actively promotes international collaboration in neutron scattering.
