Sahal Yacoob came to Northwestern University with a Master’s degree in Applied Mathematics from the University of Cape Town. He was a Luminosity expert on the DO experiment and Fermilab and measured the W boson mass with and uncertainty of 0.025%. After graduation he joined the new South African effort on the ATLAS experiment at CERN, first at the University of Wittwatersrand, then at the University of KwaZulu-Natal. He has moved back to Cape Town as a Lecturer in Physics on ATLAS as of summer 2015. See news from Sahal on the ATLAS Blog.
