Diversity is Strength! 

Dr. Wenwen Fang

I joined the Walther group in 2018 after I received my PhD degree in Material Science at Aalto University. I am working on nanocellulose materials and my future research will be focused on developing advanced hybrid hydrogels to meet the requirements for cell culture and manipulating cell functions in 3D microenvironments. 

Dr. Xinlong Fan

I earned my doctoral degree from Northwestern Polytechnical University in China. Now I am a CSC/DAAD funded postdoc in the Walther group and I study on spatial and time-programmed control of nanofibril self-assembly.

Dr. Ralf Hanselmann

Staff scientist with a background in physical polymer chemistry

Dr. Jiaqi Guo

Jiaqi studied in China and Finland and joined us after his PhD at Aalto University in Helsinki. He is now an Alexander von Humboldt postdoctoral fellow and looks at functional nanocellulose materials.

Dr. Indrajit Maity

Indrajit joined Walther Lab in early 2019 after obtaining his Ph.D from Indian Institute of Technology Indore (IIT Indore) in 2015 followed by a long term postdoctoral stay at Prof. Gonen Askenasy Lab in Ben-Gurion University of the Negev, Israel. His research interests focus on broad range of topics from supramolecular self-assembly to system chemistry including dissipative system, self-replication and non-linear phenomena such as bistability, oscillating reaction networks. Currently, he is working on the development of mechanical training-based polymer memory materials under out of equilibrium.

Dr. Avik Samanta

Avik joined Walther Lab in 2017 after earning his Ph.D. from the University of Münster, Germany in 2015 followed by a postdoctoral stay at the Northwestern University, USA. His research interests span a broad range of topics focusing largely on macrocyclic chemistry, artificial membrane, and dissipative self-assembly. Currently, he is developing kinetically driven self-assembly pathways using a symbiotic control of thermal responsiveness and sequence-specific hybridization of DNA multiblock polymers

Dr. Xuyang Yao

Xuyang Yao obtained his B.S. degree in applied chemistry in 2011 and Ph.D. in applied chemistry in 2016 under the supervision of Professor He Tian from East China University of Science and Technology (ECUST). During his PhD, he also worked in a collaborative project that combined supramolecular self-assembling systems with nanopore technology with Professor Yitao Long’s group. After obtaining his PhD, he worked for one year in the same institute with Professor Xiang Ma to study room-temperature-phosphorescence materials before moving to the University of Freiburg as post-doc for the joint FRIAS-USIAS project between Profs. Andreas Walther and Nicolas Giuseppone. Xuyang Yao will also work at the University of Strasbourg for half of the project period. His research interest focuses on controllable and functional supramolecular self-assemblies, polymers, and supramolecular light-responsive systems and optical materials.
