Professor Jansen's research relates mainly to mathematical modelling in biology. To understand how biological systems work, and how biological processed operate he develops mathematical models and analyse these. For instance, we can learn how a disease spreads, and what factors contribute to its spread by studying a mathematical model for disease spread.
His work spans several areas in biology. He is active in mathematical ecology, where he has worked on the effects of space and dispersal on the dynamics of populations. He has modelled and analysed the dispersal behaviour of several species. He has also investigated the dynamics of bumblebee colonies and investigated how stress can contribute to the decline of pollinator populations.
He is interested in evolutionary ecology. An areas to which he has contributed to in particular are the evolution of altruism and cooperation. He studies this for various species and settings. An area he enjoyed working on was how recognition, in the form of green beards, can facilitate the evolution of cooperation. A further area in which he works is the evolution of pathogens, in particular the evolution of virulence.
He has worked extensively in mathematical epidemiology and on the formulation of models for various infectious diseases. He has worked on measles, meningococcal disease and HIV. He has contributed to a theory for the use of bacteriophage to control bacteria. An interesting aspect of mathematical epidemiology that he has developed is the interplay between human behaviour and the spread of an epidemic. This has been important to understand the effect control measures for covid-19.
Neil graduated from the University of Durham (BA (Hons) Econ) in 1988, before moving to McGill University (Montreal) to read for a PhD in Economics, which was completed in 1995. From 1991 to 1995 he was a Research Officer in Economics at the Centre for Socio-Legal Studies, Oxford, and a lecturer in Economics at Pembroke College, Oxford. He moved to Surrey in 1995, and became Professor of Economics in 2004 (serving as Head of Department from 2004-2009).
Professor Neil was a Visiting Professor at the Research Institute of Law and Economics (Erasmus University, Rotterdam) from 2011-2015. Between 2007-2018, Neil was an Executive Committee member of the Royal Economic Society, serving as Chair of the Society's Conference of Heads of University Departments of Economics (CHUDE) from 2007-2012 and as Conference Secretary from 2012-2018. He is currently a member of the Economics and Econometrics sub-panel for REF 2020 (for both the Criteria and Assessment phases of the exercise) and an Associate Editor of the International Review of Law and Economics.
Professor Ben-Gad obtained his BA in Economics at Hebrew University of Jerusalem and his MA and PhD from the University of Chicago. He has worked in the Research Department of the Bank of Israel, and taught at the University of Houston and the University of Haifa.
He joined City as a Reader in 2007 and served as Head of Department between 2010 to 2013. His research focuses on Dynamic Macroeconomics with applications to taxation, public debt, the economic effects of immigration, as well as the emergence of multiple equilibria in models of economic growth.
Between 2014 to 2016, Professor Ben-Gad served on the US National Academy of Sciences panel on the The Economic and Fiscal Consequences of Immigration. In 2011 he completed research funded by an ESRC grant that is funded by HM Treasury and HMRC on fiscal policy and immigration.
Professor Ben-Gad has recently appeared on the BBC, CNBC and in the Wall Street Journal discussing the global financial crisis. In 2017 he was appointed a Fellow of the Royal Society of Arts (FRSA).
Paul Levine received a first-class BSc and a PhD, both in Mathematics, from the University of Manchester. He then taught and researched in the area of applied mathematics at Liverpool Polytechnic and the Polytechnic of North London before joining South Bank Polytechnic in 1972.
His move into economics began at South Bank as the result of collaborative research with Sam Aaronovitch into merger activity and a year studying for an MSc in economics (distinction) at Queen Mary College followed in 1977. In 1984 he became a senior research officer at the Centre for Economic Forecasting, London Business School and was appointed Professor of Economics at the University of Leicester in 1989. In 1994 he moved to the University of Surrey.

Joe Pearlman (MA MSc PhD) is a Professor of Economics at City University London. He obtained his PhD in Control Systems from Imperial College, and subsequently obtained an MSc in economics from LSE. He has spent short periods as a research associate at both the European Central Bank and the International Monetary Fund.
Professor Pearlman's research relates mainly to monetary policy and expectational learning. Currently his research is extending to cover macroprudential policy. In the past, he has researched into trade, growth and migration.
