Two New Emmy Noether Research Groups at Faculty II!

The Faculty II is proud to welcome Timo de Wolff and Johannes Teichert as leaders of Emmy Noether Research Groups at Faculty II. Timo de Wolff came to TU Berlin in July 2017 where he works at the Institute of Mathematics at the boundary between real algebraic geometry, non-linear optimization and application problems from the natural and engineering sciences. Since 2016, Johannes Teichert is a junior professor at the Institute of Chemistry of TU Berlin working in the area of synthetic chemistry.

Timo de Wolff got his doctorate from Goethe-Universität in Frankfurt for his dissertation titled “On the Geometry, Topology and Approximation of Amoebas”. Before coming to Berlin he had a postdoctoral position at the Universität des Saarlandes in Saarbrücken and was a Visiting Assistant Professor at Texas A&M University. With his Emmy Noether Group, he is investigating the non-negativity of multi-variate real polynomials. Answering this question is hard, so the proof of non-negativity is done by certificates, typically sums of squares (SOS). These can be verified by semi-definite optimization (SDP). But unfortunately SOS/SDP cannot be used efficiently for all problems arising from applications.

Thus the goal is to establish new certificates of non-negativity. Sums of nonnegative circuit polynomials (SONC) are such a new type of non-negativity certificate. SONCs are independent of SOS and were developed by Iliman und de Wolff in 2013. Timo de Wolff already proved that SONC-certificates can be calculated via geometric programming (GP) and relative entropy programming (REP) with partly extremely low runtime. At TU Berlin he plans to continue the development of SONC-certificates and their corresponding optimization problems, to implement software for their application and to tackle problems deriving form applications in the natural and engineering sciences.

Johannes Teichert did his PhD with Ben Feringa at Rijksuniversiteit Groningen in the Netherlands. His dissertation had the title “Catalytic Asymmetric Synthesis of Heterocycles”. He was a Postdoc at ETH Zürich and came to Berlin with a “Liebig-Stipendium” in 2013. His research centers around the development of sustainable catalytic reactions – one of the key challenges of contemporary synthetic chemistry. Sustainable reactions bear the key advantage that they can provide compounds of interest to society (such as agrochemicals or pharmaceuticals) with little or ideally no harmful impact on the environment. The goal of his research program is to develop dihydrogen-mediated reductive coupling reactions with easily accessible catalysts employing first row transition metals (with a special emphasis on copper and nickel). By using dihydrogen (H2) versatile building blocks for organic chemistry can be provided with minimal waste generation. In this manner, a key contribution to the development of sustainable synthetic methods should be made.
