Professor Gautam Mitra and DrCormac Lucas have worked together since 1984 and have successfully executed many consulting assignment in the domains of Optimisation, Planning under Uncertainty, Asset Allocation and Risk Analytics. In the year 2000 they set up OptiRisk Systems together with a few of their PhD research students. In the early days (2000- 2008) the company used to draw upon the research results of CARISMA: The Centre for the Analysis of Risk and Optimisation Modelling Applications, Brunel University. CARISMA was a world class research centre founded by Professor Mitra. Since 2009 Gautam Mitra has held a visiting Professorship (honorary) in the department of Computer Science (UCL); with Computational Finance specialisation. The source of research results has accordingly shifted. The focus of the leading edge products and services offered by the company have also evolved. Almost all the members of the technical team possess research degrees. The team members are drawn from an international background and between them speak a wide variety of languages, thus enabling OptiRisk to interact with clients from across the globe.
OptiRisk has recently (June 2015) renewed its accreditation by he "Investor in People" Initiative of the UK Government and has achieved Bronze level of the IiP. The company has also been assessed and approved by certified international systems to the quality administration systems, standards and guidelines of BS EN 9000 - 2000..
