Student Advising and Research:

If you are a VSU math major who is interested in doing undergraduate research, or a graduate student who is interested in doing research in applied differential equations, celestial Mechanics, or mathematical biology, you are welcomed to contact me for possible advising and Research Assistantship. Here is the list of undergraduate students I am previously advised. Summer 2015, undergraduate students use differential equations to model the 2014-2015 Ebola outbreak in West Africa. Here are their findings and presentations (Ebola in Liberia, Ebola in Sierra Leone)

Dr. Xie's research interests include:

  • Dynamical System
  • Celestial Mechanics, N-body Problem, Central Configurations, Hamiltonian System
  • Nonlinear Partial Differential Equations (Elliptic Type)
  • Mathematical Biology

Research Grants:

PIC Math program at Virginia State University (2014-2015)

Research Initiation Award:Central Configurations, New Variational Method and Periodic Solutions in Celestial Mechanics  (NSF-HRD:1409939, 2014-2016)

Publications (all published papers available in pdf format).
