I work to uncover what lies beyond our currently incomplete understanding of both particle physics and cosmology.<\/span><\/p>\n<p><span>I particularly enjoy thinking about how physics at the smallest scales&#8212;where new, microscopic particles may interact with each other through yet undiscovered forces&#8212;can be discovered using the physics at the largest scales, which determine the structure and evolution of our Universe. My work combines aspects of both theoretical and computational physics, all applied to finding ways of uncovering new physics in current and future experimental data.<\/span><\/p>\n<p>Please visit the <a href=\"https:\/\/sites.bu.edu\/cosmology\/\">BU cosmology group website<\/a> for more information.<\/p>\n<p class=\"x_MsoNormal\"><strong>Selected publications:\u00a0<\/strong><\/p>\n<ol type=\"1\" start=\"1\">\n<li class=\"x_MsoNormal\"><span>Hongwan Liu, Wenzer Qin, Gregory W.
