Dr. Christian Vogler is the director of the Technology Access Program. He is a principal investigator within the Rehabilitation Engineering Research Center (RERC) on Telecommunications Access, with a particular focus on the accessibility of web conferencing and telecollaboration systems. In his role at the RERC, he is involved in bringing consumers and industry together on accessibility issues, as well as developing prototype technologies for improving the accessibility of such systems.
Prior to joining TAP in 2011, Dr. Vogler has worked on various research projects related to sign language recognition and facial expression recognition from video at the University of Pennsylvania; the Gallaudet Research Institute; UNICAMP in Campinas, Brazil; and the Institute for Language and Speech Processing in Athens, Greece. He also runs the DeafAcademics mailing list, a loose network of deaf and hard of hearing researchers all over the world.
Dr. Vogler passionately believes that deaf and hard of hearing people have only scratched the surface of what is possible with the Internet and mobile communication technologies, and that the most exciting technological developments are still to come. He always is on the lookout for students who are interested in communication technologies and want to make a difference in how we use them.
