Research Interests

  • Drug delivery and drug targeting using liposomes and other nanoparticulates;
  • Delivery of biomacromolecules including DNA, siRNA and proteins using liposomes


Dr. Xin Guo graduated from Fudan University, formerly known as Shanghai Medical University, School of Pharmacy with a bachelor of science and from Duquesne University School of Pharmacy with a master of science, both in medicinal chemistry. He earned his doctor of philosophy from University of California San Francisco in pharmaceutical chemistry. Dr. Guo has been at University of Pacific since 2003.

In his spare time, he enjoys singing and playing chess.
