Biographical Sketch

Sergiy is a Reader / Associate Professor in Cyber-Physical Systems at Newcastle University (UK). Sergiy joined Newcastle University from Australian National University (Australia) in September 2019. Prior to being a faculty member at ANU, Sergiy was a postdoctoral researcher at the Institute of Science and Technology Austria (IST Austria). His research focuses on the development of algorithms and tools to model and analyze complex concurrent and distributed systems. In particular, Sergiy aims at providing scalable solutions for automatic analysis of cyber-physical systems using the techniques on the interface of the areas of verification, control and artificial intelligence. Sergiy has over 40 publications in top hybrid systems, verification and AI venues, such as EMSOFT, HSCC, TACAS, AAAI, IJCAI and ICAPS targeting multiple applications domains such as autonomous systems, systems biology and operations research. He has co-chaired several events (FORMATS'22, HSCC'21, SNR'15-17, NSV'15-16, MOCHAP'15), served on the program committees of around 50 conferences and workshops; he was also ACM SIGBED Review Editor in 2017-2019. Sergiy's work has won several awards such as Best Repeatability Evaluation Package Award at HSCC'16, Best Tool Award at ARCH'16 and Best Paper Award at HVC'14. He started the International Workshop on Symbolic-Numeric Methods for Reasoning about CPS and IoT in 2015 (collocated with CAV, Cyber-Physical Systems Week and ETAPS in different years). In order to ensure his research has a lasting impact in the community, Sergiy actively pursues research collaborations and has been supported by a number of agencies and companies. These include US Air Force Office of Scientific Research, Defence Science and Technology Group (Australia) and Toyota (USA). His Ph.D. and M.Sc. degrees are from the University of Freiburg (Germany).

Open Positions

I always look for excellent  PhD students interested in developing novel methods to design and analyze cyber-physical systems (e.g., autonomous cars). The main focus will be on the formal verification of hybrid systems, i.e., dynamical systems exhibiting mixed discrete-continuous behaviour. Depending on the interest and background of candidates, research can include topics from AI as well, e.g., AI planning and machine learning.  


Candidate profile:

  • strong background in Computer Science and/or Mathematics  (particularly numerical methods, differential equations, control and optimisation theory) 
  • solid programming skills in C++/Java/Python/Matlab 
  • should have completed, or about to complete, a Bachelor's or Master's degree in Computer Science or related areas

  • SpaceEx with guided state space exploration, a version of hybrid model checker SpaceEx adjusted towards solving falsification problems, i.e., our primary goal is to find a path to the bad states as fast as possible. To do that we have introduced two heuristics which prioritize symbolic successors during the exploration of the state space of a considered hybrid system: box-based heuristic and PDB heuristic. The following presentation describes both the approaches.
  • SpaceEx with assume guarantee abstraction refinement  allows for the compositional analysis of large systems consisting of multiple components. In order to build assumptions we introduce an appropriate abstraction based on location merging. We integrate the assume-guarantee style analysis with automatic abstraction refinement.
