- Computational pathway design for biotechnological applications

The goal of the project is to establish a new biotechnological platform for the production of hydroxy-amino acids, since the current production of these important building blocks is very expensive. Enzyme engineering, systems biotechnology and metabolic engineering will be used in a synthetic biology approach.

Head of the group of Molecular Enzyme Technology and Biochemistry (Faculty of Chemistry) at the University of Duisburg-Essen. My research interest is on archaeal physiology with a special focuss on the central carbohydrate metabolism of (hyper)thermophilic Archaea and its regulation. The aim is to gain a systems level understanding by the combination of modern highthrouput analyses with classical biochemistry and molecular biology.

Archaea possess many novel enzymes and pathways and our aim is

The oxidative Weimberg pathway for the five-step pentose degradation to α ketoglutarate from Caulobacter crescentus is a key route for sustainable bioconversion of lignocellulosic biomass to added-value products and biofuels. Here, we developed a novel iterative approach involving initial rate kinetics, progress curves, and enzyme cascades, with high resolution NMR analysis of intermediate dynamics, and multiple cycles of kinetic modelling analyses to construct and validate a quantitative model
