Sergii is a member of the Department of Applied Mathematics and Theoretical Physics and Centre for Quantum Information and Foundations. His current research interests are Quantum Computation and Quantum Information.

I'm looking for two highly-motivated qualified postdocs to work on quantum algorithms for computational genomics in relation to Wellcome Leap's "Human and Pathogen Quantum Pangenomics" project.

Together with Tom Gur I am co-organizing Cambridge-Warwick Quantum Computing Colloquium 

I'm leading the following projects:


Postdoctoral research associates

Thorsten Wahl (2022-)

Subhayan Roy Moulik (2023-)

Carolin Wille (2023-)

PhD students

Mitchell Chiew (2020-)

Wilfred Salmon (2021-) [Jointly with Hitachi Cambridge Laboratory]

Josh Cudby (2022-)

Orson Ye (2023-) [MRes student]

Summer research students

Chenguang Guan (co-supervised jointly with Laurens Lootens)

Tejas Archarya (co-supervised jointly with Bipasha Chakraborty)

Adam Wills
