Magnus Neuman started his research career as an employee at Scania CV AB where he was offered to do a PhD in control theory in cooperation with KTH (Royal Institute of Technology) in Stockholm, working on optimal control problems in hybrid electric powertrains. But after a year or so he accepted an offer to do a PhD in his home town Härnösand with Mid Sweden University, where he defended a thesis in physics, studying radiative transfer problems and solution methods in industrial contexts. Complex networks have however fascinated Magnus ever since his undergraduate studies at Umeå University and Universidad de la República, Uruguay, and after some substantial paternity leave he joined Icelab where he now is doing data analysis with methods from network theory, with applications in for example epidemiology and ecology.
