# New junior researchers

In the fall of 2021 six junior researchers joined the Centre for Quantum Mathematics. The six include three postdocs, two PhD students and one visiting junior researcher. The six youthful researchers will stay at QM in 1-3 year positions.

We are giving a warm welcome to the six new junior researchers who have joined QM in the second half of 2021. A short presentation:

**The first postdoc, Ikshu Neithalath** received his PhD in Mathematics in 2021 from the University of California, Los Angeles under the supervision of Ciprian Manolescu. His research is on algebraic invariants in low-dimensional topology. He has done work on sheaf-theoretic SL(2,C) Floer homology as well as Khovanov homology. At SDU, he will be working with Vivek Shende at the Centre for Quantum Mathematics.

**The second postdoc, Daria Poliakova**, is educated from University of Copenhagen. Poliakova obtained her PhD degree in Mathematics in 2021 under the supervision of Ryzard Nezt and Lars Hesselholt. Her main research interests are algebraic topology, homological methods in category theory and operads. At the Centre for Quantum Mathematics she will be mentored by professor Vivek Shende.

**The third postdoc, William Elbæk Mistegaard,** is educated from Aarhus University and is a former PhD student of Professor Jørgen Ellegaard Andersen. Dr. William Elbæk Mistegaard works on geometry and mathematical physics and the subject of his PhD thesis was the Witten-Reshetikhin-Turaev topological quantum field theory. After completion of his PhD thesis, he was awarded a postdoctoral fellowship at Institute of Science and Technology Austria under the mentorship of highly esteemed Professor Tamas Hausel. In 2021 he was awarded a Carlsberg postdoctoral fellowship to continue his research at Centre for Quantum Mathematics, University of Southern Denmark mentored by Prof. Jørgen Ellegaard Andersen.

One of the new **PhD students, Zhongyu Zhang**, is being supervised by Professor Vivek Shende, and is interested in the expressibility and intuition of mathematics in quantum physics in particular to approach globalisation and infinity(/random) issues.Zhongyu Zhang obtained her master’s degree in physics in 2020 from ETH Zurich, under the supervision of Prof. Niklas Beisert and Dr. Ben Hoare with the thesis title: “Yang-Baxter deformations based on Belavin-Drinfeld r-matrices ”. Afterwards, she started an on-going project under the supervision of Dr. Nima Moshayedi and Prof. Cattaneo with the topic on the globalisation ofBV-BFV formalism.

The other **PhD student, Emil Hössjer**, is also being supervised by Professor Vivek Shende, and is interested in mathematical physics. He graduated with a master's degree in theoretical physics from Uppsala University under the supervision of G. Festuccia with a thesis on generalized global symmetries and their uses to understand the dynamic of quantum field theories and has previously done work on Equivariant localization, Generalized global symmetries and abelian TQFT's.

Further **Christopher Kuo** from the University of California, Berkeley, USA, is currently visiting the center. He is pursuing a PhD in Mathematics in Berkeley under the supervision of Vivek Shende. Christopher Kuo’s research lies in the discipline of geometry and topology, especially microlocal sheaf theory and its interaction with symplectic geometry. At the Centre for Quantum Mathematics, he will be working as a research assistant for Vivek Shende for the academic year of 2020-2021.
