Meng’s research focuses on earthquake physics, such as the long-term tectonic process like plate motions and crustal deformation. He has used both observational and numerical approaches to develop advanced source imaging techniques. These imaging techniques could be applied to recent large earthquakes, such as in 2010 in Haiti and Chile, the 2011 Tohoku-Oki quake off the coast of Japan (which caused tsunami that damaged the nuclear reactors in Fukushima), the 2012 Sumatra earthquake in Indonesia and the 2013 Okhotsk deep-focus earthquake in Russia.
