I am a Reader (equivalent to an Associate Professor in the North-American academic system) in Data Science at the Department of Geography at University College London, where I lead the Intelligent Social Systems Lab.
PhD Studentship Available
We are advertising a PhD studentship for a project on HCI and intelligent mobile systems for digital mental health together with Anna Cox. If you are interested please get in touch. All the details about the application process can be found here. Closing date: 18 August 2017.
Two papers have been accepted in the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT) and will be presented in the main research track of ACM UbiComp’17 as part of the new journal-based conference model. In “MyTraces: Investigating Correlation and Causation between Users’ Emotional States and Mobile Phone Interaction” we show that users’ emotions have a causal impact on different aspects of mobile phone interaction. We also discuss the causal impact of the use of specific applications, reflecting the external users’ context such as socializing and travelling on the emotional state of the individual. In “Understanding the Role of Places and Activities on Mobile Phone Interaction and Usage Patterns” we present an in-depth study of the relationships between users’ activities and interaction with notifications and apps.
Our PrefMiner paper has been listed in the ACM Best of Computing Notable Books and Articles for 2016.
We wrote an article on “Avoiding Pitfalls when Using Machine Learning in HCI Studies”, which will appear in the July 2017 edition of ACM Interactions: the paper discusses some of the issues related to the use of machine learning in HCI, especially in behavioural studies.
We have published the pre-print “A Comparison of Spatial-based Targeted Disease Containment Strategies using Mobile Phone Data” on the design of spatial disease containment strategies based on a real-world cellular network call dataset from Ivory Coast. More specifically, the paper discusses the impact of the socio-geographical heterogeneity on disease transmission dynamics. In particular, we consider the spreading of the Ebola virus as a case study.
Our paper “Designing Effective Movement Digital Biomarkers for Unobtrusive Emotional State Mobile Monitoring” has been accepted at the 1st ACM Workshop on Digital Biomarkers colocated with ACM MobiSys 2017. The paper discusses the design of novel digital biomarkers for the inference of emotional states based on the fine-grained characterization of the mobility patterns of a user over time. You can download the paper from here.
We wrote a short survey on “Sensing and Modeling Human Behavior Using Social Media and Mobile Data”. The article will be part of a book that will be published in the next months. The pre-print of the article is available on ArXiv.
Our paper “Anonymous or not? Understanding the Factors Affecting Personal Mobile Data Disclosure” has been published in ACM Transactions on Internet Technology. The article contains an experimental evaluation of the different factors affecting users’ disclosing choices of location and social interaction information. The paper can be downloaded here.

Ph.D. Students and Postdoc Opportunities
PhD Students. I am looking for students interested in pursuing a Ph.D. in my lab. If you are interested please contact me by email in order to discuss potential funding sources for your studies (such as available postgraduate studentships and other potential sources of Ph.D. funding). At the moment, we are advertising a PhD studentship for a project on HCI and intelligent mobile systems for digital health together with Anna Cox. If you are interested please get in touch. All the details about the applications can be found here. Closing date: 18 August 2017.
Postdoctoral Researchers. I am also happy to discuss other opportunities for working in my group, including fellowships such as those offered through the Newton Fund, EU Skłodowska-Curie Actions or the Fulbright Scholar Program.
Current areas of interest of my lab include:
- Computational and mathematical modelling of human behaviour and social systems using mobile data and other digital sources (social media, user-generated content, etc.);
- Ubiquitous computing;
- Applied machine learning.
Main application areas are:
- Digital health;
- Data science for social good;
