Biography

Tobias Hartung studied mathematics (physics minor) at TU Dresden graduating with a Dipl. Math. in 2013. He obtained his PhD in mathematics from King’s College London in 2015. Having held academic positions at King’s College London and the University of Bath, he joined Northeastern University London in 2022. Tobias is currently an Associate Professor in Computer Science.

Qualifications

PhD in Mathematics, King’s College London (2015)
Diplom Mathematics with Physics Minor, TU Dresden (2013)

Research

Tobias’s research is in the intersection of functional analysis, mathematical foundations of physics, quantum computing, and algorithm design for high energy physics. His main research focus aims to study the mathematical structures present in physical systems and using them to design custom algorithms and analysis tools – both quantum and classical – to overcome the obstacles that currently prevent many high energy physics simulations.
