Raja Kushalnagar Professor and Director, Information Technology Program

I am the Director of the Information Technology program in the Department of Science, Technology and Mathematics at Gallaudet University in Washington, DC. Our IT program has grown rapidly in the past few years, and we are exploring new concentrations and minors for the program, including cybersecurity and data science. I primarily teach human-centered computing with a focus on accessible computing, and application development courses. I also teach cybersecurity related courses at both the introductory and specialized levels. My research interests encompass the fields of accessible computing and accessibility/intellectual property law, with the goal of improving information access for deaf and hard of hearing individuals. In the accessible computing field, I investigate information access disparities between hearing and deaf. For example, I investigate how deaf individuals acquire information through speech-to-text, e.g., enhanced captions that provide visual cues to non-speech information. In the accessibility/intellectual property law field, I advocate for updates in accessible and intellectual property law, to incorporate accessible computing advances such as automatic captioning/subtitling. I have published several peer-reviewed publications and received grants in the fields of accessible computing, accessible law and intellectual property law.

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. He can be found on Twitter @lukOlejnik

As a recognized industry guru and technology evangelist, he's embraced the continued evolution of the related arts and sciences. Reprints of some of his articles are available at generaltitles.com.

His recent credits include visual effects development & supervision, color grading, look development, film editing, and title design for feature films. Credits include work on films such as the recent live-action Beauty and the Beast for Disney. Other clients include Sony/Columbia, Warner Bros., and Universal.

His interests here with the W3, AGWG, Silver Task Force, and the Low Vision Task Force, are partly motivated by his personal struggles with low vision. His visual impairments, coupled with his extensive experience in color, typography, and visual arts & sciences make him uniquely qualified to lead the research and development of the Accessible Perceptual Contrast Algorithm project, as well as co-authoring guidelines on visual contrast and accessible readability for WCAG 3.

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.
