Rikutaro (Rik) Yoshida

- High Energy Physics

Rik Yoshida is an experimental physicist in the High Energy Physics Division. Currently he works on the ATLAS experiment at the Large Hadron Collider (LHC) located at the CERN Laboratory in Geneva, Switzerland. He is an expert in a variety of areas in High Energy Physics (HEP) including Higgs searches, electroweak physics, quantum chromdynamics, proton structure and HEP experimental techniques.

Rik received his PhD from Northwestern University and has worked on HEP experiments at Fermilab, the DESY laboratory in Hamburg, Germany and at CERN. From 2003 to 2005 he was elected to be the scientific leader of the ZEUS experiment at DESY by the 300 international physicists of the ZEUS collaboration. He has served on the main scientific advisory committee (LHCC) for the LHC at CERN. Rik is currently a member of the main scientific advisory panel for the HEP part of the DESY laboratory, and a Fellow of the American Physical Society.
