Welcome to my homepage!

It is generally believed that, when the Big Bang occurred about 13.7 billion (13,700,000,000) years ago, matter and anti-matter were produced in equal amounts. Our present universe exists almost completely of matter. Study of the decay of B-mesons (particles that contain a b-quark) is used to investigate the matter-antimatter asymmetry in nature.

Some of my research highlights:

• We study this asymmetry with the LHCb (2) experiment at CERN in Geneva. (Nobel Prize 2008 was awarded to M.Kobayashi and T.Maskawa for the discovery of the origin of this broken symmetry.)
• With "Rare Decays" like Bs->mu+mu- (theory) we aim to find New Particles beyond the Standard Model.
• Through "CP violation" like with Bs->Ds+K- (theory) we investigate matter-antimatter differences.
• LHC news: Latest news. Expert info: (LHCb Display) (beam) (lumi+energy) (Event display)
• Construction of the Outer Tracker Detector for the LHCb experiment; Improved LHCb OT performance in Run II.
• 13th International Conference on B-Physics at Hadron Machines, Beauty2011
  and 1st Amsterdam Particle Physics Symposium APPS were held in Amsterdam

For this work NWO rewarded me with a Vidi in 2007 and a Vici in 2017.
