I am a Project Assistant Professor at National Institute of Informatics (NII) in Tokyo, Japan. I work in the project ERATO MMSD headed by Prof.Dr. Ichiro Hasuo.

From November 2020 to October 2022, I was a postdoctoral researcher working in the Rigorous Software Engineering Group headed by Prof.Dr. Rupak Majumdar
at Max Planck Institute for Software Systems (MPI-SWS) in Kaiserslautern, Germany.

I obtained my PhD degree in Software Engineering from School of Software Engineering, Tongji University in July 2020. (advisors: Miaomiao Zhang and Naijun Zhan).
Before that, I also obtained my Bachelor degree and Master degree both in Software Engineering from the same university.
From 2017 to 2020, I was also a visiting PhD student at SKLCS, Institute of Software, Chinese Academy of Sciences where I was advised by Prof.Dr. Naijun Zhan.

Tools

  • NIL: A learning-based tool in Mathematica that is dedicated to synthesizing nontrivial (reverse) Craig interpolants for the quantifier-free theory of nonlinear arithmetic.

  • OTALearning: This prototype tool is dedicated to actively learning deterministic one-clock timed automata (DOTAs). (The evaluated artifact by TACAS-2020 is also archived in the Figshare repository.)

  • RTALearning: This prototype tool is dedicated to actively learning real-time automata (RTAs). A real-time automaton can be viewed as a timed automaton with only one clock which resets at every transition.

  • RTAOpacity: A prototype tool for deciding the language-opacity of real-time automata (RTAs).

  • VCELDI: A prototype tool to verify continuous-time Extend Linear Duration Inviriants (ELDIs) formulas againt timed automata (TAs).

  • NAPL: A declarative network algorithm programming language.
