魏建華，男，1999年在山東大學獲得凝聚態物理學博士學位，博士學位論文獲得山東省優秀論文獎。畢業后，先后在韓國首爾國立大學物理系，香港城市大學物理系，以及香港科技大學物理系和化學系工作與訪問；2000年破格晉升為山東大學副教授；2007年調入中國人民大學，現被聘為中國人民大學教授，博士生導師。

主要從事過渡金屬氧化物材料中軌道、電荷、自旋和晶格振動多個自由度耦合所導致的新奇量子效應、有機導體材料與分子納米結構中的非平衡輸運問題，以及多體強關聯系統的非平衡輸運問題方面的前沿研究，已在SCI主流學術期刊上發表學術論文五十余篇。

當前課題：

1納米體系中的非平衡量子輸運問題，包括有機納米體系中載流子與外場相互作用及量子效應研究；有機納米電子學中的動力學阻抗和憶阻研究等。

2.非平衡量子多體問題的計算方法研究。這套方法基于費因曼影響泛函理論，其表達式是一套（對系統-環境相互作用）非微擾的密度矩陣動力學方程組，可利用計算機高效地數值求解。密度矩陣動力學可求解從零溫到高溫、從弱關聯到強關聯等不同參數范圍的非平衡（兼容平衡）量子多體問題。本課題將發展一套高效普適的求解非平衡多體相互作用的數值計算方法，以研究當前凝聚態物理同強關聯作用相關的問題。

Dr. Jianhua Wei was born on the 20th, October in 1972. He was graduated from Physics Department of Shandong University. In 1999, he received his Ph.D. in Shandong University, with his doctoral thesis being received the Outstanding Paper Award of Shandong Province. Dr. Jianhua Wei was appointed to be a teacher in Shandong University till 2007 and then he transferred to Renmin University of China. Presently, Dr. Jianhua Wei is the professor and supervisor of the Doctors in Physics Department, Renmin University of China.

Dr. Jianhua Wei is mainly engaged in following frontier researches: non-equilibrium quantum transport theory; orbital physics in transition metal oxide materials; and non-equilibrium many-body theory, etc. He has been published over 50 research papers in the mainstream academic journals.

At present, Dr. Jianhua Wei’s main research interest is to numerically solve the non-equilibrium quantum many-body problems. The formula is a set of non-perturbative dynamical equations of the density matrix, which can be efficiently solved by computers. This method can deal with different temperatures as well as different correlation strengths for many non-equilibrium many-body problems.
