Professor Jin Wang received his BEng from Jiangxi University of Science and Technology, MSc from University of Science and Technology Beijing, and PhD from Kyushu Institute of Technology, Japan. He is currently a Professor at Xi’an University of Architecture and Technology, and serves as Deputy Director of Shaanxi Key Laboratory of Membrane Separation as well as Shaanxi Institute of Membrane Separation Technology. His research interests focus on nanoconfined ion‑transport behaviours, and functional nanochannel membranes targeting ion separation, critical‑resource recovery and clean‑energy conversion. He has been the principal investigator for multiple national‑level research programs including grants from the National Natural Science Foundation of China, the National Key Research and Development Program of China, the National Young Talents Program of China, and Shaanxi Provincial Outstanding Young Scientist Fund. His group has published a series of peer‑reviewed papers in *Nature Communications*, *Matter*, *Energy & Environmental Science*, *Angewandte Chemie International Edition*, *Water Research* and other high‑impact journals. His work covers two‑dimensional lamellar membranes, stimuli‑responsive nanofluidic systems, osmotic energy harvesting and selective ion sieving from complex aqueous solutions.
