Youssef S. Hassan, a graduate student at NIST, is working on developing advanced optical lattice clocks (OLCs) for next-generation quantum timekeeping. His research focuses on reducing uncertainties in these clocks, particularly by suppressing the black-body radiation shift, which is currently the largest source of error. Hassan is also working on cooling clock atoms to extremely low temperatures (sub-uK) to better characterize lattice-induced light clock shifts and developing techniques to control the spatial distribution of atoms within the lattice. He graduated with a B.Sc. in Physics from the University of Science and Technology at Zewail City, Egypt in 2017.
