He got his BSc on Computational Mathematics from the School of Mathematical Sciences at Peking University in 2004 and PhD on Nonlinear Optimization at the Chinese Ac 10f8 ademy of Sciences in 2009. He has been a visiting scholar in many places, including Germany, United States, Hong Kong and Singapore. Dr Liu's current research interest is computational methods for optimization, mainly focusing on nonlinear least squares, sparse optimization and matrix decompositions.
