Biography

I am a Reader (Associate Professor) and the PGR Director in the School of Computing Science. I am also a member of the Glasgow Interactive SysTems (GIST) research section and I lead the SIRIUS Lab research group (https://mkhamis.github.io/mkhamis/team/), focusing on research at the intersection of Human-Computer Interaction (HCI), and User Privacy & Security.

Previously I was a Lecturer at the University of Glasgow from 2018 until 2022. I received my PhD from Ludwig Maximilian University of Munich (LMU) in Germany, where I was supervised by Florian Alt, and Andreas Bulling. I also worked as a Research Associate at the German Research Center for Artificial Intelligence (DFKI) in Germany, and at the German University in Cairo (GUC) in Egypt.

My research has received funding (>£1 million, out of which >£920,000 as PI) from the Royal Society of Edinburgh, the UK National Cyber Security Centre (NCSC), the UK Foreign, Commonwealth and Development Office, the UK Engineering and Physical Sciences Research Council (EPSRC), Meta/Facebook Reality Labs, REPHRAIN and the PETRAS National Centre for IoT Systems Cybersecurity.

I have 130+ publications, including 15 papers at ACM CHI, the top conference in Human-Computer Interaction, four of which received honourable mention awards (top 5% of ~3000 submissions). I have also published at top conferences and journals in HCI and Security, like ACM TOCHI, ACM TOPS, USENIX Security, IEEE S&P, PETS, IJHCS, ACM UIST, UbiComp/IMWUT, CSCW, ACM ETRA, ACM ICMI, PACM IMWUT, and ACM MobileHCI.

I regularly serve on editorial boards and program committees, such as IJHCS (since 2020) and ACM IMWUT (2021-2023), and ACM CHI (2019-2023), CHI LBW, PerDis, MUM, and others. I was the General co-chair of ACM PerDis 2019 and I am General Co-Chair of ACM ETRA 2024 in Glasgow. I also organized several workshops like PETMEI, Eye4Sec, ArabHCI and Human-Drone Interaction.

As an Associate College Member for EPSRC, I review research grants proposals submitted to the EPSRC. I previously served as an academic advisor for the UK's Commonwealth Scholarship Commission. I advise the Extended Reality Safety Initiative (XRSI), and have previously advised Emteq Labs and Edify.

Many of my accomplishments resulted from collaborations with scholars in Germany, UK, France, USA, Japan, Finland, Austria, Italy, Slovenia, and Egypt.

I am a member of ACM and SIGCHI, and a founding member of Cairo ACM SIGCHI chapter, and co-organized the first ArabHCI workshop at CHI 2018.

Research interests

I worked in a diversity of topics within HCI, privacy and ubiquitous computing. In particular, I am active in the fields of eye tracking, pervasive displays, usable security, and user privacy. My contributions are at the crossroads of user privacy and ubiquitous computing:

- Usable Security and Privacy: I contributed to both: (1) understanding threats to user privacy that are caused/facilitated by ubiquitous technologies, such as thermal attacks (CHI'17, Honorable Mention), and shoulder surfing (CHI'17, MUM'17, INTERACT '19, ETRA'20), and (2) inventing novel ubiquitous systems for protecting user privacy and security on mobile devices (CHI'20, CHI'19, ICMI'17, MTI), public displays (IMWUT, ETRA'19, PerDis'17), and in VR (TOCHI, IEEE VR'19, USEC'17).

- Designing Gaze-based Systems: I contributed to comprehensively understanding and addressing challenges of gaze interaction on ubiquitous devices, such as mobile devices (CHI'18, MobileHCI'18) and public displays (UIST'17, UbiComp'16, MUM'16), as well as proposing novel concepts that employ gaze to address problems on public displays (CHI'18, IMWUT, PerDis'17), and mobile devices (ICMI'17). I published survey papers that reflect on prior work and set the agenda for future research in eye tracking on mobile devices (MobileHCI'18) and eye tracking for security applications (CHI'20).
