I founded and led the quantitative user experience research team at Google. This work involves analyzing large-scale data (e.g. from usage logs or surveys) to generate insights about how products are being used. We also define and track metrics to measure the impact of changes to the user experience, for example using the HEART framework.

I used to lead user experience research for web search, including using eye-tracking to study how people scan a search results page.

Before Google, and after my PhD, I spent some time at Microsoft Research in Cambridge, working as a consultant to the Integrated Systems group, in collaboration with Alan Blackwell and Rachel Jones. Our projects included improving history mechanisms for web browsers, and exploring new web search interfaces for mobile devices.

Alan Blackwell and I also worked together to produce a new electronic edition of Ivan Sutherland’s 1963 PhD thesis on Sketchpad.

I did my PhD at the University of Cambridge Computer Laboratory. My research combined elements of human-computer interaction, information retrieval, image retrieval, and information visualization.

I carried out experiments considering whether arranging a set of images on the screen according to their mutual similarity (so that images which are alike are placed close to each other) is helpful to the user when browsing the set. Below you can see two different layouts of a set of 100 images of Kenya: in the first, they are arranged according to visual similarity, and in the second, for comparison, they are placed in a default ordering.
The main experiment used graphic design students as the participants, with a task involving selecting photographs from a set to illustrate a given piece of text.

There are many ways in which image similarity can be defined; I used measurements based on low-level visual properties (such as colour and texture), and on textual captions. To construct the visualisations, I used multidimensional scaling.

I was also interested in how people would organize and browse their personal photographs once the usage of digital cameras was more widespread, and conducted a six-month field study (in collaboration with AT&T Laboratories Cambridge) where the participants were given digital cameras and copies of AT&T’s Shoebox software. I analyzed usage logs, and interviewed the participants at the beginning and end of the study.

In the summer of 1997 I worked with Matthew Chalmers as an intern at UBS Ubilab in Zürich, Switzerland. We developed a system to record users’ paths through the Web, using a form of collaborative filtering to recommend resources via sharing of paths.

The system was also featured in the book Digital Information Graphics by Matt Woolman.
