I have been conducting research at the crossroads of Human-Computer Interaction and Ubiquitous Computing for the past 10 years. During this time, I significantly contributed to two emerging areas of research: Usable Privacy and Security and Interaction in Public Space. My major research achievements are
- invention of new authentication concepts (CHI’16) as well as novel authentication mechanisms based on gaze (CHI’12), behavioral biometrics (CHI’16, CHI’18), and images (Ubicomp’14, MobileHCI’15); in-depth investigation of various threat models such as thermal attacks (CHI’17, Honorable Mention) and shoulder surfing (CHI’17); and the investigation of authentication in new application areas, e.g., VR (USEC’17).
- creating a comprehensive understanding of audience behavior in public space — in particular, conveying the interactivity of public displays (Looking Glass, CHI’12, 204 citations, Best Paper Award), building a behavioral interaction model (The Audience Funnel, ACM Multimedia’10, 257 citations), the most widely cited methodology paper for evaluating public displays (How to evaluate public displays?, ACM PerDis’12, 97 citations), and a text book on Pervasive Displays (Synthesis Lectures, 2013).
- I have published over 140 refereed archival publications listed in DBLP. Most of these were published in journals and proceedings of international conferences with equivalent standing (acceptance rate <25%).
- My publications are well cited by the community (>3200 citations) with six publications having been cited more than 100 times. I have an h-index of 28.
- I have the second most papers in ACM SIGCHI 2017 among 2100 authors (https://goo.gl/eXLMnH )
- In my career I received 3 Best Paper Awards and 5 Honorable Mention Awards.
