Dónal Fitzpatrick

I am presently a lecture (Assistant Prof.) at the School of Computing Dublin City University. In 1999 I received my Ph.D. from the School of Computer Applications Dublin City University; the title of my thesis being "Towards Accessible Technical Documents: Producing Braille and Spoken Output from LaTeX Documents". In 2000, I was awarded the prestigious Fulbright Fellowship to continue work in the area of accessible mathematics, and also to investigate how GIS data could be made usable by blind people. In 2001, I returned to DCU to take up the faculty position alluded to above. Both my teaching and research activities revolve around accessibility. Presently, I teach undergraduate courses in web design and HCI. In both modules, I base the content and assessment around the notions of Universal Design. I have been Principle Investigator on several national and EU grants. the most recent of these (Enhanced Government Learning EAGLE) was a multi-million Euro grant to introduce online training to local authorities across the EU.

Lukasz Olejnik

Lukasz Olejnik comes from an information security background. His previous engagements include security engineering work at the Poznan Supercomputing and Networking Center and CERN. Lukasz holds a PhD from INRIA (Grenoble) in privacy. His research interests include information and computer security and privacy, especially as applied to online interactions with a special emphasis on the Web, user data disclosure and dissemination problems and privacy-sensitive matters related to Web browser functionalities, as well as Web security. In his research, he analysed user tracking and profiling on the Web. Examples include studies of Web history leaks, as well as privacy and transparency analysis of Real-Time Bidding. Lukasz published his works in venues such as NDSS, ESORICS, WEIS and Phys Rev. He has publications spanning fields such as quantum cryptography and privacy. He co-created the What The Internet Knows About You, a demonstrator of privacy risks related with Web browsing history disclosure via Web browsers. This project included a crucial educational component. Lukasz is also responsible for How Much Are You Worth project, which provided a transparency-aiding browser extensions and was capable of submitting data from users. The data was then leveraged to quantify the value of user data in Real-Time Bidding. Lukasz believes that private matters should stay private, but privacy risks should become public.

Andrew Somers Color Science Researcher

Andrew Somers has a broad base of experience in Television and Film in Hollywood, with major credits listed as public record on iMDB. He's been working with color, images, titles/text, and the related engineering issues since before personal computers were capable of displaying images. He's been at the forefront of digital imaging technology and was involved at the beginnings of Digital Cinema, and has been a part of the evolution of the related technologies ever since.

His specific work the last 21 years has been primarily Visual Effects Development & Supervision, Color Grading, Look Development & Editorial, and Title Design for feature films, including work on films such as the recent live-action Beauty and the Beast for Disney. Additional related work is in web design and other graphic design including book design and other print media.

This experience is coupled with a background in broadcast engineering, related vision and perception research, and coding (C/C++, PHP, Javascript, etc.). His current project is the research & development for a new color theory for a book he's writing on that subject.

His interests here with the Accessibility Working Group, Silver Task Force, and the Low Vision Task Force are partly motivated by his personal struggles with visual impairments. He expects to utilize his extensive background in digital imaging & engineering to provide research and development toward improved standards and guidelines relating to visual accessibility for the WCAG.

Johannes Wilm PhD, Anthropology

Johannes (German/Danish/Swedish) has studied social sciences and humanities with a focus on the Americas, Politics, and History in Norway, the UK and Sweden. He has conducted fieldwork in Douglas, Arizona and Nicaragua for extended periods of time and has lived in several Latin American countries. To pay for his other activities, he started doing (open source) web development with and has tried several times to create academic writing systems for non-technically inclined users so that others could take over more of his technical responsibilities in the creation of academic journals. Since 2012 he has worked on the web-based editor Fidus Writer, and in the process he has found that it made a lot of sense to connect with other, larger JavaScript editors to push for improvements in this area and to engage with browser makers through the W3C. Johannes is therefore mainly active in the Editing Taskforce.
