Håkan T Johansson

Forskningsingenjör at Chalmers, Physics, Subatomic and Plasma Physics

As a research engineer, I provide advanced software and computing hardware support to the subatomic physics group.I am involved in various nuclear physics experiments at European laboratories, primarily GSI, but also CERN-ISOLDE. My main scientific interest lies in the efficient use of computers in all aspects of experiment preparations, execution and analysis, as well as high-performance computations for nuclear theory.For more information, visit my personal web page.
