Simulating our World: Rigorous Mathematics towards Smart Computational Modelling from Cell Biology to Geophysics

Applied scientists spend a great deal of effort in quantifying properties and phenomena in as diverse areas as physics, biology and medicine, chemistry, geology, economics and finance, in the form of so-called models, typically posed in the language of mathematical formulas. Most often, advanced such models come in the `implicit' form of differential equations. Classical examples include the equations of planetary motion, equations of heat conduction, equations of morphogenesis, and so on.

Mathematicians study and solve such equations, since it is their solutions that are typically the quantities we are after. The ever increasing complexity of such models and/or their application in complex scenarios needed by technological innovation renders the calculation of solutions to respective models impossible using classical mathematics. The invention of computers in the second half of the 20th century has been driven for the largest part by the need to solve, even approximately(!), such models of scientific and/ or practical interest.

To this end, scientists have embarked in the development of computer algorithms aiming to solve such models, thereby providing realistic computer simulations. The complexity of the contemporary models often requires unrealistic computer processing power, rendering such simulations intractable. Aiming to break this complexity barrier, I will discuss the development of a next generation, smart, reduced complexity computational modelling framework based on rigorous mathematical foundations and how we envisage that such complexity considerations will become increasingly important in the coming years.

Emmanuil Georgoulis, Professor of Mathematics

Emmanuil 200x266.jpgEmmanuil Haralambous Georgoulis was born in Athens, Greece in 1977. He graduated from 2nd Lyceum of Halandri in 1994, before embarking for his undergraduate studies in Mathematics at the University of Athens graduating in 1998. He then went to Cambridge to study for his Master's in Mathematics (a.k.a. Part III of the Mathematical Tripos) from which he graduated with 'Distinction' in 1999 and moved to Oxford for his D.Phil. (Oxford way of calling PhDs) in Numerical Analysis under the supervision of Endre Suli, completed in 2003. Having worked as a Stipendiary Lecturer at Oxford for a year and a half (2002-2004), he moved to Leicester as a Lecturer (’04-’08), then Senior Lecturer (’08-’10), Reader (’10-’16), prior to be promoted to Professor in 2016.

Since 2014 he also holds a part time appointment at the National Technical University of Athens, Greece’s top/most selective academic institution. He has held invited professorial appointments at the Institute of Applied Calculus of CNR-Rome (2008) and at Hausdorff Institute in Mathematics, Bonn (2017). He has had 8 PhD students graduating so far (all from Leicester) and 3 more on the way. He has given more than 10 plenary/keynote talks at international conferences and workshops. He has more than 40 journal publications and has just completed his first research monograph to be published by Springer. His research has been funded by EPSRC, The Leverhulme Trust, the EU and Industry (General Electric, BGS).
