Info.:

Dr. Mingjian Wu is a staff scientist at the Institute of Micro- and Nanostructure Research at Friedrich-Alexander-Universitaet Erlangen-Nuernberg in Germany. He obtained Bachelor's and Master's degrees in Materials Science from Hunan University, China, and Doctor degree (summa cum laude) in Experimental Physics from Humboldt-Universitaet zu Berlin in 2014.

He is an enthusiastic "nano-photographer" with over 15 years of experience in electron microscopy. His expertise lies in developing and applying advanced microscopy, diffraction, and spectroscopy techniques—integrated with in situ, operando, and data science approaches—to gain unique insights into modern functional materials. His research interest lie in the investigation of organic semiconductors, in particular, developing methods and techniques to unravel structures that are difficult to study. He has published ~80 peer reviewed articles. In 2023, he received the "Outstanding Paper Award" from European Microscopy Society for contribution of developing 4D-STEM method for organic solar cell materials.
