Luk and his collaborator Yifang Wang were awarded the 2014 Panofsky Prize "for their leadership of the Daya Bay experiment, which produced the first definitive measurement of θ13 angle of the neutrino mixing matrix.

[7] Luk is currently a Hung Hing Ying distinguished visiting professor in science of The University of Hong Kong, and a senior visiting fellow of the Jockey Club Institute for Advanced Study at the Hong Kong University of Science and Technology.

Luk has published a number of papers on neutrino oscillation (see selected publications), including his 2014 Panofsky Prize winning research at the Daya Bay Nuclear Power Plant.

Along with a small group of young colleagues, he initiated Fermilab E756 to measure the magnetic dipole moment of the Omega-minus hyperon.

He discovered polarization of the charged anti-cascade hyperon that laid the experimental foundation for investigating CP violation in charged-cascade decays.
