缅北禁地

Introduction

I'm a Professor of Economics. My work focuses on empirical microeconomics, typically using large-scale datasets and microeconometric techniques to investigate questions mainly drawn from labour economics, the economics of crime, health economics, international economics and urban economics. I am also currently Deputy Head of the Economics Group. I joined 缅北禁地 in September 2010, first as a Lecturer until 2013, from then as Senior Lecturer until July 2017 and from August 2017 to April 2018 as Reader in Labour Economics. Before coming to England I was a PostDoc in Economics at Leuphana University Lueneburg, Germany, where I also completed my doctoral degree in Economics in 2009 as well as Master's degrees in Business and Economic and Social Sciences.

Research Themes

My research examines how people and places respond to shocks, incentives, and institutional change. Using applied microeconomic methods and often highly disaggregated spatial data, I study labour markets, crime, policing, and urban change.

Labour Market Adjustment: I examine how workers and local labour markets respond to disruption, including mass layoffs, workplace unionisation, and the labour-market consequences of COVID-19. This work is motivated by a broader interest in how economic shocks alter employment, risk, and inequality over time.

Crime, Policing, and Neighbourhoods: Much of my recent work focuses on crime, policing, and local disorder. I study the spatial distribution of crime, public responses to police behaviour, and the incentives that shape offending, with particular attention to how these processes vary across neighbourhoods.

Urban Change and Local Economies: Another strand of my research looks at how neighbourhoods change as local economies evolve. This includes work on high street decline, neighbourhood composition, and the effects of changing amenities and local economic conditions on communities and social outcomes.

Research Interests

Empirical microeconomics, in particular in labour economics, health economics, economics of crime, international economics and urban economics.

My research is in applied microeconomics, with a focus on labour markets, crime, policing, and urban change. Across these areas, I am interested in how individuals, institutions, and neighbourhoods respond to shocks, incentives, and local economic change. Much of my work asks how behaviour adjusts when established economic relationships are disrupted, when local environments change, or when institutional settings alter the costs and returns associated with different choices.

One strand of my research examines labour markets and worker adjustment. In this work, I study how workers and local labour markets respond to adverse shocks and institutional change, including mass layoffs, workplace unionisation, and the labour-market consequences of COVID-19. These projects are linked by an interest in adjustment: how people respond when employment conditions change, how risks are transmitted through labour markets, and how disruption can reshape inequality and longer-run economic outcomes.

A second major strand of my research focuses on crime, policing, and neighbourhoods. Using highly disaggregated spatial and administrative data, I examine the geography of crime, public responses to policing, and the incentives that shape criminal behaviour. This work is motivated by an interest in how offending responds to changing local opportunities and constraints, and in how interactions with the state are experienced and interpreted by civilians. More broadly, it connects questions in economics with concerns that are central to criminology and public policy, including deterrence, neighbourhood disorder, and unequal exposure to policing.

A third strand of my research studies urban change and local economies. Here I am interested in how neighbourhoods evolve in response to economic decline, changing amenities, and shifts in the commercial and social life of local areas. This includes work on neighbourhood composition, housing markets, high street decline, and the wider consequences of local economic change for communities. A recurring theme is that neighbourhoods are not simply passive settings for economic activity: changes in local institutions, services, and amenities can have broader effects on behaviour, wellbeing, and social outcomes.

Although these strands span several fields, they are connected by a common empirical and conceptual approach. Empirically, my work relies on applied microeconometric methods and often combines survey, administrative, and geospatial data. Conceptually, it is unified by an interest in how people and places adjust to changing incentives and environments. This often places my research at the boundary of labour economics, urban economics, and the economics of crime, while also speaking to wider debates in sociology, criminology, and public policy.

My current research continues to build on these themes, with particular emphasis on local economic shocks, neighbourhood change, crime, policing, and the consequences of institutional withdrawal or disruption in local areas.

Prospective PhD students

I'm happy to supervise students in my areas of interest. Feel free to drop me an email in these cases to discuss an application. Given my interests, PhD projects for which I make some level of sense as a supervisor will inevitably involve data work, often using large scale micro data, and advanced econometrics. I am not interested in time series stuff or the vast majority of finance topics (and you honestly don't want me to supervise this sort of stuff either as I wouldn't have a clue).

My teaching is guided by a simple principle: economics and econometrics matter most when they help students make sense of important real-world problems. Across my modules, I aim to move students beyond learning techniques in isolation and towards understanding how theory, evidence, and judgement come together in good applied work. Whether I am teaching undergraduate econometrics, advanced causal inference, research practice, or sustainability and climate change, my goal is to help students become careful, critical, and confident users of evidence.

A consistent feature of my teaching is that I build from intuition to method to application. I want students to understand not only how a technique works, but why it is needed, what assumptions it relies on, and where it can go wrong. In econometrics, this means starting from substantive questions and simple empirical settings before moving to more advanced topics such as omitted variables, measurement error, heteroskedasticity, panel methods, discrete choice models, and causal inference designs including difference-in-differences, instrumental variables, and regression discontinuity. My aim is rigorous understanding without losing sight of the question the method is meant to answer.

My teaching is also strongly research-led. Across my modules, students engage with published empirical papers, including frontier research and, where useful, examples from my own work. This allows them to see how economists actually frame questions, justify empirical strategies, test assumptions, and interpret findings. In this way, students encounter economics not as a closed technical system, but as a way of engaging with live social and policy questions.

I place particular emphasis on helping students read and evaluate evidence critically. Students are encouraged to ask where identification comes from, what the relevant counterfactual is, which assumptions are doing the work, and how robust the conclusions really are. This is reflected both in classroom teaching and in assessments that ask students to analyse data, evaluate research designs, and construct evidence-based arguments rather than simply reproduce material mechanically.

More broadly, I try to make the practices of academic and professional work visible. This includes helping students formulate research questions, work with real data, communicate findings clearly, and understand the often uncertain process through which good research develops. My aim is to combine rigour, relevance, and intellectual honesty, so that students leave my modules with strong analytical tools and a clearer sense of how to use them responsibly.
