Welcome to my page!

I currently work as a lecturer at PHENIKAA University in Hanoi, Vietnam. Prior to this, I held the position of a postdoctoral researcher in the Complex Analysis Group at the Complex Analysis Group at the Faculty of Mathematics, University of Vienna. During that time, I received support from FWF-projects led by Bernhard Lamel and Friedrich Haslinger. I was a Principal Investigator of the Lise Meitner FWF-Projekt M2472-N35, a postdoctoral researcher at University of Vienna under the FWF-project I01776 by Bernhard Lamel (09/2017-08/2018), and a postdoctoral research associate at Texas A&M University at Qatar (2015-17) under the NPRP project 7-511-1-098 by Nordine Mir. Furthermore, I had the privilege of being a Visiting Assistant Professor at the Department of Mathematics, University of California at Irvine where I was supervised by Song-Ying Li.

In 2012, I earned my Ph.D. degree at the University of California at San Diego, where I had the privilege of being mentored by Professor Peter Ebenfelt. My Ph.D thesis has the title  "Transversality of CR mappings between CR submanifolds of complex spaces" and can be downloaded from eScholarship.

In 2020, I earned my Habilitation at the University of Vienna, with the dissertation title "Some aspects of CR manifolds."

My research interest are Several Complex Variables and CR geometry. For more details, see Research page or my Curriculum Vitae.
