Our Research areas:
Our core knowledge is in deep understanding of lignin chemistry and technology. We are working on engineering of optimal lignins for specific applications by elucidating the correlation between process conditions, lignin structure, lignin properties and application performance. To achieve this challenging, yet very important task, we cooperate with artificial intelligence groups and application experts at our Department, University and worldwide.

Lignin is the only large renewable source of green aromatic chemicals and polymers and therefore the key player in the modern and future biorefinery. However, lignin commercialization for high-value products is very challenging due to its very complex nature and the high variety of different technical lignins. Our group is addressing this challenge by developing best lignin types for specific applications via understanding the correlation between process conditions, lignin structures and properties and their performance in specific applications using advanced methodology (new biorefinery processes, cutting-edge analytics, artificial intelligence).
We are looking for further fruitful cooperation with different groups working in various areas of lignin production and applications in academia, research institutes and industry.
1. Lignin Analytics
We focus on state-of-the-art analysis of lignin and lignin carbohydrate complexes
Comparison of Different NMR Methods:
These methods are complementary;
The best method is dependent on the research task and substrate type
Lignin structure on a functional level can be described comprehensively by advanced 13C NMR.

2. Lignin Engineering:
Lignin valorization requires tremendous analytical efforts and method development including lignin structural analysis and, especially, high‐throughput methods for the evaluation of lignin performance in specific applications.
New and comprehensive lignin structure–performance relationships are urgently needed in order to be able to engineer lignins and lignin properties to certain application requirements.
3. Integrated Biorefinery
We focus on:
- Full valorization of the feedstock
Ligno-cellulosic synergism in biorefinery streams
Integrated biorefinery: full valorization of the feedstock
One-pot reactive extraction of lignin - an efficient strategy for producing upgraded lignins
