Dr. Sophie Van Der Zee
I am a post-doctoral researcher in the Security Group of Cambridge University's Computer Laboratory, working on the Deterrence of Deception project led by Prof. Ross Anderson. This project is aimed at understanding how deception in online settings is different from face-to-face lying, and how we can utilize this information to prevent people from lying. In addition to my work as a post-doctoral researcher in Cambridge, I also hold two honorary Research Fellowships. I am a College Research Associate at King's College, Cambridge, and together with my colleague David Modic I work on a research project on identifying victims and perpetrators of Internet Fraud: To deceive or be deceived. The second Honorary Research Fellowship concerns another practical application of social psychology research. Within the Department of Medical and Sport Sciences at Cumbria University in the UK, I am involved in Health Psychology related research on topics such as pain perception and self-image.
I hold a PhD in Forensic and Social Psychology from Lancaster University (UK), completed under the supervision of Prof. Paul J. Taylor and Dr. Lara Warmelink. For my PhD project I used motion capture equipment to measure if nonverbal mimicry is affected by lying. Previous education includes a Master's degree in Psychology and Law (Honors/Cum Laude) from Maastricht University in the Netherlands, and a Bachelor degree in Social Psychology from Utrecht University in the Netherlands.
My research focuses on different aspects of deception. During my PhD I investigated the interpersonal aspects of lying measured automatically using motion capture equipment. Combining technology and forensic psychology has introduced me to the benefits of interdisciplinary research and I extended this approach during my post-doc research. Currently, in addition to detecting deceit, I am interested in the more fundamental question of why people lie. The aim is to disentangle which factors contribute to a person’s decision to lie, and consequently, to test if this information can be used to deter people from lying. An application area for this research is understanding how we can reduce fraud.
Decepticon 2015: International Conference on Deceptive Behavior
Together with an amazing scientific and local committee, I am organizing the first interdisciplinary conference on deceptive behavior. Previously, deception research has been fragmented across conferences in many different disciplines, sub-disciplines and countries, and the aim of Decepticon 2015 is to bring all those practitioners and academics together. Topics that will be discussed include verbal and nonverbal cues to deception, interview techniques, use of technology to detect deception (e.g., polygraph, fMRI, EEG, eye-trackers and motion capture suits), preventing deception and deterring fraud, cultural differences, border-control, lying about intentions, self-deception, malingering and socially acceptable lying (e.g., poker, magic and white lies). The conference will take place 24-26 of August 2015 in Cambridge (UK). Unfortunately, the submission deadline has passed; we received the impressive number of 106 submissions, but of course you can still register to attend the conference and listen to all these inspiring talks.

Media coverage & outreach
- I featured in Stephen Fry's English Delight show in the episode "Words fail me", broadcasted on BBC radio 4. In the show, which also featured Steven Pinker, Fry discussed the link between emotions and language, and how this is affected by lying (11 August 2015).
- Together with my colleague Ronald Poppe I demonstrated our motion-based lie detection method and future directions to the Dutch news, NOS op 3. We also demonstrated our lie detection method on BNN radio (Dutch; from minute 8.00; 2 August 2015).
- I was interviewed live on TV for BBC's Crimewatch Roadshow about our motion-based lie detection research, including a demonstration of the equipment (16 July 2015).
- I participated in a panel debate on 'the necessity of lying', together with Prof. Rae Langton from the University of Cambridge, Prof. Tom Sorrel from the University of Warwick and our great host Peter Curran. The panel was organised as part of the Philosophy and Music Festival 'How the lights get in' at Hay. Video and article are now online.
- I gave an interview to BBC Radio 4 Cambridgeshire about a recent report on identity theft (27th of May, 2015)
Our research on automatically detecting deception based on body movements received a significant amount of media attention, including English videos by Dailymotion and Fox, Dutch videos by Zoomin TV, WNL Vandaag TV, and RTL Boulevard TV (NL), radio coverage on BBC's Naked Scientists (UK), BBC World Radio (UK), Radio538 (NL) and Radio 2 (NL), newspaper articles in The Guardian (UK), The Telegraph (UK), Daily Mail (UK), Cambridge News (UK), The Register Mail & Guardian (SA), NRC (NL), Algemeen Dagblad (NL), Volkskrant (NL), KIJK (NL), 7days (kids magazine, NL), Trouw (NL), BNR (NL), Nieuws (NL), RTV Utrecht (NL), De Morgen (BE) HLN (BE), and we were mentioned on several websites such as Bruce Schneier's Blog, International Business Times, Computer World UK, Engadget, Techie News, PC World, News Nation, Tumblr, My Science, TweakTown, ABP Live & Lancaster University King's College Cambridge, and Xsens Customer Case.

Interested in using eye-tracking equipment in an applied way? I am looking for an MSc/MPhil student who would like to find out if we can use saccadic eye-movement to detect deception. Please contact me if you're interested in conducting experimental research and write your dissertation on this topic. Email: sophie.van-der-zee|AT|cl.cam.ac.uk
