I’m very glad to now be an associate editor for the ACM Transactions on Computer-Human Interaction. I was just in the door, and I already have a paper to organise reviewers for… and, yes, I’m struggling already to get people signed up for the expected date. Conforming to an old norm?

Improving the t-SNE data visualisation algorithm via stochastic sampling

Another project started very recently, with the above title. It’s great to be working with Alistair Morrison again, as we look at ways to apply the ideas we developed (many years ago!) for fast spring models (a.k.a. force-directed placement) with tSNE algorithms. Somewhat bizarrely, this is funded by the US Navy. We are grateful but also somewhat surprised.

Ethical Design of Apps for Assessing Mental Health

This is a EPSRC Impact Acceleration Award project getting off the ground now, on phone apps that collect personal data that can be used to predict social anxiety.

I am enjoying working with Angus Ferguson and Marek Bell on this short (4 month) project. It is based on an undergraduate project by Dimitris Eleftheriou, that basically reproduced an experiment by Boukhcheba et al. reported at the 2017 Ubicomp workshop on mental health.  We will extend Dimitris’ work that let the app operate in a way that allows most/all of the personal data (collected via Denzil Ferreira’s AWARE framework) to be kept on the phone, by adding and evaluating features that allow participants to maintain feedback and control over what happens to the data sent from their phone to us.

Even as I write this, it reminds me of old Ubicomp work from the 1990s, by Victoria Bellotti and Abi Sellen, on feedback and control… We’ll see whether/how that might weave into this work…

EPSRC NetworkPlus on Human Data Interaction starting

This network plus grant is starting up, and the investigators (Hamed Haddadi, Ewa Luger, Elvira Perez-Vallejo, Atau Tanaka and me) met up for the first time within the grant, to make plans such as prioritising our themed workshops, setting up a web site and mailing list (connecting to the existing site/list at

One point that came up was that the ~45 grants we will give out will be especially suitable for PhDs and early career researchers, and so we should connect to the CDTs in relevant areas. We can’t guarantee funds to particular CDTs, but can certainly help them as part of our matchmaking and workshop processes. More generally, if you are interested, let us know…


It’s easier to edit and save stuff on this WordPress site, instead of the one inside the university.

Here’s a link to the old DCS server, for reference… and a picture from a fine day out in the Cairngorms. Extra points if you can spot the climber near the top of the Milky Way route…
