My research interests stretch from PDEs to graph theory, from theoretical stuff into multidisciplinary applications

I was awarded a CBE for services to mathematics research and development July 2005

I am a Member of Council of the Biotechnology and Biological Sciences Research Council,  2008-

I am a Member of the MOD's DSAC, 2008-

I was President  of the Institute of Mathematics and its Applications 2006 – 2008.

I was a Member of Council of the Engineering and Physical Sciences Research Council, and Chair of EPSRC User Panel, 2000-2004

I was a Member of the Isaac Newton Institute National Advisory Board, 2004-2010

I received an Honorary Doctorate from Oxford Brookes University, 2006  

Peter Grindrod is a mathematician working within the commercial sector for over seventeen years, most recently managing the development and application (and deployment) of mathematical methods to gain business insights from very large databases for large customer facing companies.

He has a PhD in the mathematical analysis reaction diffusion systems, and is the author of a graduate textbook on pattern formation within medical, biological and chemical systems, concerning the theory and application of semi-linear parabolic systems.

o       Graduated in Mathematics from Bristol University  (1978-1981)

o       Completed a PhD in mathematics at Dundee University (1981-1983)

o       Held a post doctoral fellowship at Dundee Universty (1983-85): research in functional analysis, nonlinear dynamical systems,..

o       Appointed Junior Lecturer in mathematics at the Mathematical Institute, Oxford University, and Research Fellow at Brasenose College, Oxford (1985-88): research in nonlinear PDEs.

o       Held an SRC Advanced Fellowship at Oxford University (1988-89) working primarily on problems in mathematical ecology, chemistry, and physiology; developing an eikonal approximation (the geometry and motion of internal transition layers) approach to problems for excitable reaction diffusion systems, and problems of multiple fronts within large geochemical systems. He also lectured on Mathematical Biology including problems with coupled oscillators.

o       Joined an international oil sector and environmental risk management consulting company (1989-98), building up and managing a mathematical modelling group working on multidisciplinary projects in the UK, Europe, US and Japan. He was responsible for client development, particularly within Japan and the EU, developing collaborative and commercial relationships. His own research ranged from the application of fractals to simulating subsurface environments (micro medium structure controlling channelling flow and dispersion phenomena at the macroscopic scale), and non-linear multiphase (solutes, gases, colloidal) dispersion processes, fully coupled chemical-temperature–and hydration systems, through to the development of frameworks for estimating uncertainties within risk assessments, and the analysis of public risk perception. His work on nonlinear PDEs continues most recently with results existence symmetry breaking and stability of solutions for semi-linear parabolic equations with non-linear boundary conditions. He also developed analytics, based on state space embedding techniques for time series, for ForEx trading useful to financial institutes.

o       He was co-founder and Technical Director for a self-funded start–up company, Numbercraft Limited, (1998-2003) to supply services and software to commercial sectors: to retail and consumer goods manufacturing and supply, in particular. The need to extract structure and information, rapidly, and exhaustively, from large commercial data sets drove this: there was market pull from almost all data rich retail and consumer goods companies. Such problems occur within many fields. More and more businesses collect data on products, customers and transactions, whilst media channels and communications have become more diverse. The challenge was to derive valuable insights by interpreting and modelling such data whilst avoiding hypothesis driven approaches. Numbercraft, differentiated by the excellence in analysis, worked with all of the major grocery retailers in the UK (Tesco, Sainsbury’s, ASDA, Safeway, Waitrose, Carrefore, Ahold) and their largest suppliers (Coke, Pepsi, P&G, Unilever, RBK, Deageo, .. and so on). Numbercraft owned all of the IP generated through its work and licensed this to third party software and service providers. Numbercraft, designed to be a five year project, and was exited on time and completely acquired by Lawson Software (St Paul, US) in 2003.

o       Head of Lawson Software’s Retail mathematics based research and technology group (2003-2006), responsible for the specification and derivation of mathematical algorithms developed and embedded within Lawson’s Retail InSight software products, and also responsible for managing mathematicians who consult to major retailers and suppliers within the UK and Europe. Responsible for the group’s relationships with major retailers in the US, such as Safeway Inc in CA, and internationally.

o       Developed range dependent (scale free) graph concepts applicable to post genome (proteome, metabolome) large interaction data sets. Introduced the notion of inverse problems as a way of attributing functional roles to proteins, and developed collaborative (currently EPSRC funded) research with Bath and Strathclyde universities, and the Beatson Laboratory (Glasgow), to develop and encourage the use of mathematical methods (spectral theory, maximum likelihood modelling) in resolving problems associated with complexity and massive networks.

o       Assisted Bath’s Mathematics and Engineering group with strategy and cross theme development for their Critical Mass Complexity Grant (BICS).

o       Directed an EPSRC “sandpit” on environmental risks and their assessment for regulatory purposes, 2006.

o       Advised on Systems Biology funding through the BBSRC/EPSRC.

o       He is interested in knowledge transfer and in particular how to encapsulate and grow value within activities (such as those within pure science, including mathematics) that are essentially people led. He chaired the EPSRC’s first Knowledge Transfer Centres funding panel (2006), and also currently taking part in their Knowledge Transfer Challenge evaluation panel (2006).

 

Peter has published articles and refereed papers, when time and confidentiality restrictions permit, the most recent being in the field of range dependent random graphs and their application to modelling large small world proteome data sets. He has worked in various fields including complex system modelling, dynamical systems analysis of signals, continuous and discrete optimisation and searches, range dependent graph theory, Bayesian forecasting methods, self tuning Markov models, fuzzy logic, finite mixture modelling, and so on.
Since 2000 Peter has been engaged with the EPSRC, both as member of Council and as Chair of the User advisory panel (which goes into much greater depth than Council). Regular assessment and balance reviews were carried out; whilst this was a time of considerable changes in the nature of operations for all of the research Councils, an of course RCUK and OST. In particular the devolvement of responsibility for doctoral training and knowledge transfer to universities (DTAs and CTAs); the development of sector management; the funding of adventure in research, the growth of the life-sciences interface(s) and doctoral training centres; the development of cross council activities such as GRID, bioinformatics, energy and basic technology programmes. Peter also saved on the Wellcome Trust’s Functional Genomics panel, providing a mathematical view on matter s related to bioinformatics.
