AREA OF EXPERTISE:
My main research interests are in the area of Computational Science and High Performance Computing encompassing stochastic modelling, Monte Carlo methods and algorithms, Parallel Algorithms, Parallel Computing, Scalable Algorithms for Large Scale Systems and Applications. In particular, I develop scalable Monte Carlo algorithms for variety of supercomputing architectures for Linear Algebra, Computational Finance, Environmental Models, Computational Biology etc. In addition the research focuses on scalable and fault-tolerant algorithms for petascale architectures and the exascale architecture challenge. These are applied through various collaborations to applications in diverse areas.
In more detail my research interests are:
Developing the fundamental mathematical methods needed to model complex physical, chemical and biological systems, spanning different length and time scales (these involve models for air pollution, computational biology, computational finance, security applications). In particular, Monte Carlo and various stochastic methods are developed and designed.
Developing scalable algorithms for advanced architectures that scale over 1000’s and 10,000’s of processors (these involve work with Oak Ridge National Lab) In particular, scalable Monte Carlo algorithms are developed for Environmental Models, Computational Finance and Linear Algebra. The research focuses on scalable and fault-tolerant algorithms for the petascale architectures and the exascale architecture challenge.
Collaborative and Cloud Computing, developing environments enabling scientists to efficiently implement the above mentioned models and algorithms and run them on advanced computer architectures and developing tools to manage, analyse and visualize the data that results from computational experiments is of interest here. These involved gEclipse workflow environment, distributed environments developed by several of my PhD students for CAVEs, tools such as JMAST (Multicast Application Sharing Tool) and COCO (Collaborative Computing Platform)), VieGen (developed by Dr. A. Haffeggee) and my current work on EUBRazilOpenBio project.
I work on combining High Performance Computing approaches with 3D visualisation and VR to solve efficiently large scale problems in the security area, Computational Biology (molecular docking and drug design),
2
environmental modelling (Air Pollution Modelling) and in collaboration with the other visualization and supercomputing centres.
E-Learning (joint work with Nia Alexandrov) focusing on novel curricula design and development, E-Learning software development and integration, technology enhanced learning (coordinated GENIUS project, involved in E-LANE, VALUE and ACCESS EC projects).
