A newbie to the School

Post by Dr Chris Lloyd

As a new arrival in the School, I have been trying to adjust to how things work in the University. I spent my last academic year at Queen’s University Belfast on sabbatical (a year off teaching and admin responsibilities to pursue research). During this time I have been working on three book projects (not to be recommended at one go!) – an introductory text on Geographical Information Systems, a research-level book on exploring spatial scale in geography, and an edited book on segregation. Spatial scale is at the heart of my research interests; the relationships between population variables (for example, employment status and housing tenure) change as the spatial scale of measurement is adapted – the relationship will be different if we use small Census areas or large Census areas. Scale also links directly to my interest in segregation – a group may appear segregated (separated from members of other groups) if we use small Census areas, and mixed if we use large Census areas. So, we must understand scale effects if we are to characterise segregation, in the same way that we need to know something about the scale of variation in deprivation if we are to characterise deprivation.

Modelling travel time: the local time cost of travelling 100m in Belfast Urban Area.

Another interest of mine is in how we can model interactions between people using quantitative data. The places that we visit on a day-to-day basis are selected for a variety of reasons – because we work there, we have friends or family who live there, there are shops or other facilities, or we just travel through the area to get to somewhere else. Most spatial statistical methods use very simple definitions of neighbourhoods, and they are usually based on the assumption that the likelihood of travel decreases in proportion to distance from the place of residence. Part of my research explores ways to more realistically model the potential movement of people and the degree to which they interact with others – a link back to the theme of segregation.

In my short time in the School of Environmental Sciences, it has already proved to be a collegial and stimulating place to work, and I am very pleased to be moving into such a great working environment!
