- Cremona, John
Warwick Mathematics InstituteJohn Cremona works in computational number theory, in the area of elliptic curves and modular forms. He is interested in tabulating these systematically, and his database of elliptic curves, first published within a book (Algorithms for Modular Elliptic Curves, CUP (1992)), is a standard reference in the field.
Over the last five years the elliptic curve database project has become part of a much large world-wide research project called the L-Functions and Modular Forms Database (LMFDB) which was originally funded by a $1.2M US NSF FRG grant, and since 2013 is funded by an EPSRC Programme Grant worth £2.2M, shared between Bristol and Warwick, of which John Cremona is the PI. As well as Bristol and Warwick, the project has a large international team of collaborators. The project consists of a large database, hosted at Warwick, containing a substantial amount of number-theoretical data (for example including over 100 billion zeros of the Riemann Zeta Function, each to 100-bit precision) accessible by the website www.lmfdb.org, also hosted at Warwick, allowing different views of the data and showing clearly the links between different mathematical objects, some of which are still only conjectural and all of which are the subject of a large amount of research worldwide. As well as new mathematical theory, the project involves much algorithmic development, realised and implemented entirely as open source software, so that both the data and the code used to create it and display it is all fully open.
- Czumaj, Artur

E
- Epstein, David
Warwick Mathematics InstituteI work with biologists and computer scientists, making multiple images of the same tissue section, extracting different data from different images. One might compare healthy with diseased tissue. The data is voluminous and requires considerable analysis to make sense of it. The projects of interest are biomedical at the molecular level. I am concerned mostly with a project funded by BBSRC which is fundamental research that might help with diabetes.
As a separate, but related, issue, I am interested in discovering the geometry of objects that could give rise to an observed set of points in a space of many dimensions. This entails using a mixture of mathematics, computer science, statistics, intuition and common sense.
F
- Ferhatosmanoglu, Hakan
Department of Computer ScienceI am interested in building scalable data analytics and integration software. The typical process includes merging multiple types and sources of information, scaling the analysis process in terms of both size and variety of data, and protecting the privacy of data subjects. An example is to identify aggregate spatio-temporal patterns over multiple sources of geotagged data, shared via mobile devices, GPS, and social media. My work addresses data and systems challenges in building such applications for temporal and multi-dimensional data analytics.
- Finkenstädt Rand, Bärbel
Department of StatisticsMy area of research is in statistics and mathematical biology.
In particular, I am interested in analysing temporal and/or spatio-temporal data from biological systems (from single cells to meta-populations). My recent collaborations include addressing questions in chronobiology with collaborators in the Biological Sciences and Medicine. In collaboration with Francis Lévi, I am researching statistical methods for non-stationary statistical modeling and inference for circadian oscillations for research in cancer chronotherapy (see BBC video).
G
- Griffiths, Nathan
Department of Computer ScienceMachine learning for driver and vehicle monitoring based on telemetry and CAN-bus data. Using machine learning techniques we are able to make predictions about a vehicle's current environment (such as current road type) without relying on GPS and mapping data, and are able to monitor the driver's cognitive load in terms of whether they are distracted or stressed. This work is in collaboration with Jaguar Land Rover.
Influence and behaviour propagation in online and offline social networks. Using agent-based modelling and machine learning we are able to identify potentially influential nodes and targets for disruption in social networks. This has applications to social settings such as smoking cessation behaviour and product purchasing, and to law enforcement for gathering intelligence. This work is in collaboration with Sandtable Limited and West Midlands Police.

I
- Icardi, Matteo
Warwick Mathematics InstituteI am interested in the modelling and simulations of complex flows arising in problems such as electrochemical devices, subsurface and porous media, turbulent multiphase reactors. These problems are typically characterised by multiple physics and length scales and, due to their complexity, have to be addressed with an integrated modelling and data-driven approach. I am therefore interested in calibrating and validating mathematical models and estimating uncertainties by means of Bayesian inference. I am also interested in the upscaling and model reduction.

M
- MacKay, Robert
Warwick Mathematics Institute and Centre for Complexity ScienceRobert MacKay pioneered topological data analysis long before the Edelsbrunner/Carlsson wave (though this has gone largely unnoticed). The work was mostly carried out by postdoc Mark Muldoon at Warwick on an EPSRC grant with David Broomhead (Manchester): Muldoon, MacKay, Broomhead and Huke: Topology from time series. Physica D 65 (1993) 1–16. More recently MacKay had an undergraduate project student apply topological data analysis to data from a CAT scanner in WMG, and one of our Erasmus Mundus masters students applied it to EEG data with the Institute for Digital Health.
MacKay is director of the EPSRC&MRC CDT on Mathematics for Real-world systems, successor to the EPSRC DTC on Complexity Science. The CDT will train students in the development and application of models and methods to analyse data from areas like health, industry and finance. It is supported by 12 external partners: JLR, NatGrid, Thales, BT, PHE, PHW, Sciteb, Simpact, Polymaths Consulting, University Hospitals Birmingham, Birmingham School of Cancer Sciences, Pirbright, all of whom are keen to have our students work on their data. Jointly with the Urban Sciences CDT at Warwick, we have been awarded funds for a Data Analytics Platform to assist in this.
MacKay is partner in a Global Collaboration on Financial Systems Stability, coordinated by Sciteb. It has recently received funding from Barclays and Standard Chartered to plan methods to analyse stress test data for the Bank of England.
MacKay is partner in an EPSRC Maths programme bid on Urban Mathematical Analytics, led by Des Higham (Strathclyde) with Peter Grindrod (Oxford), which has recently passed outline stage. In this programme we plan to develop mathematical approaches to the analysis of data from time-dependent multi-layer networks provided by cities. The programme will link with the CUSP and other smart cities initiatives and has support from BT, Capita, IBM, Microsoft, Scottish Power, Siemens, Lloyds bank, Dunnhumby, PA Consulting, Scottish & Southern Energy, Vodafone, Bloom, Cisco, and Xerox.
