  • Biography

I am an enthusiastic “nano-photographer” with almost 15 years of experience in electron microscopy, developing and applying cutting-edge microscopy, diffraction, and spectroscopy techniques combined with in-situ and in-operando approaches and data science tools to obtain unique insights in a wide spectrum of modern functional materials.

I studied Materials Science and obtained Bachelor’s and Master’s degrees at Hunan University, China. Afterward, I moved to Berlin, Germany. I worked at the Paul-Drude-Institute for solid state electronics with Dr. Achim Trampert on structural phase stability in III-V semiconductors. With a top honor grade “summa cum laude”, I obtained doctor degree in Natural Science (Dr. rer. nat.) in Humboldt Universität zu Berlin in 2014. After a short stay in Finland (as a candidate for a Marie Skłodowska-Curie fellowship), I joined the Institute of Micro- and Nanostructure Research at FAU in 2015.

I am currently a senior staff scientist at the institute, with major roles (amongst others) as
+ scientific advisor in various projects, offering cutting-edge electron microscopy/spectroscopy expertise
+ facility supervisor/manager of a double Cs-corrected, monochromated Titan Themis and co-supervisor of a probe-corrected Spectra 200 TEMs

My current research topics cover the following aspects:
methodologies,
+ diffraction-based methods, 4D-STEM, detector technology, and data analysis routines
+ high-resolution imaging and spectroscopy of nanostructured materials and devices
+ phase contrast electron microscopy techniques (particular differential phase contrast)
+ in-situ electron microscopy techniques and novel preparation methods
materials,
+ extended defects in nano-structured semiconductors, metals, and thin films
+ nano-particulate systems, nano-alloys, and intermetallics
+ beam-sensitive organic/inorganic materials for photovoltaic and optoelectronics

Besides, I also offer teaching activities in the following curricular
+ Electron Microscopy I (Master course; in winter semesters, responsible for exercises: 2 ECTS)
+ Electron Microscopy II (in summer semesters, responsible for lecture & exercise: 5 ECTS total)
+ Lab course of Nanotechnology (Master level lab course in winter semesters: 2 ECTS)

  • Honors and awards

+ Outstanding Paper Award (OPA) by the European Microscopy Society (EMS), 2023, Awarded in Busan, Korea
+ Best poster prize at Microscopy Conference 2017 (MC2017), Lausanne, Switzerland
+ “Summa cum laude” for doctorate, Humboldt Universität zu Berlin, 2014, Germany
+ “Helmet Alexander Award” in International Conference on Extended Defects in Semiconductors 2012, Thessaloniki, Greece
