I am a senior lecturer in Computer Science at the University of Sunderland.
I hold an MSc/MPhil in Applied Mathematics and Mechanics from the Novosibirsk University, Academgorodok, Russia.
My PhD is in Application of Computer Technology, Mathematical Modelling and Mathematical Methods in Scientific Research, from the Institute of Information Technologies and Applied Mathematics, Russian Academy of Sciences.
I came to Sunderland in 2000 from Sydney, Australia where I worked for the Statistical Hydrology Unit, River Management Branch, Department of Water Resources, NSW Government; Macquarie University and University of Technology as a researcher/lecturer. In Sydney, I also ran my own consultancy business (P-Quant) in computer science, mathematics and statistics.
Data Mining, Machine Learning, Data Science, Big Data, Mathematical Modelling.
I am the author of new mathematical theory - Profile Theory, which has a number of practical applications, in the fields of Business Intelligence; Data Science, Machine Learning, Data Mining, Software/Web Engineering; Computational Intelligence.
If you you are highly motived and have a strong interest in these research areas please feel free to contact me directly to discuss relevant research opportunities.
In 1997 I invented a new mathematical theory - Profile Theory, which has a number of practical applications, e.g. in the fields of Business Intelligence, Data Science, Machine Learning, Data Mining, Software/Web Engineering, Computational Intelligence. In large measure, Profile Theory is designed to address an important class of problems, which are not addressed by the traditional theories (it includes complex systems theories) in which the central issues relate to capability and compatibility problems of complex systems and/or their elements; and determination of complex system structures. The importance of Profile Theory derives from the fact that in the real world such problems are the norm rather than exception.
Key research issues include: analysis and modelling of complex systems where capabilities and compatibilities of their elements are critical factors.
