Mark Williams Mark Williams '86, Ph.D. has a passion for creating pedagogically sound, elegantly designed digital learning experiences. His passion surfaced early in his academic career and eventually led him to start Pyramis Studios, a biomedical media communications group, where he served as president and creative director. While at Pyramis, he authored and led the development of the Sylvius project, a popular suite of software applications for teaching the structure of the human brain to medical and graduate students. Williams also spearheaded the development of award-winning web design and animation for major universities and pharmaceutical companies.

In February 2006, Williams founded Modality, Inc. to design and implement mobile educational technology solutions to problems he witnessed firsthand as a neuroanatomy graduate student and later as a medical educator at Duke University. Beginning with the launch of the Apple App Store in July 2008, Modality created more than 150 mobile applications spanning K-12 and higher education, health sciences, and consumer reference. In November 2010, Modality was acquired by mobile medical reference leader Epocrates, Inc. Williams led the expansion Epocrates' mobile development and design capabilities as the head of User Experience.

In 2013, Williams brought together a number of key Modality team members to start his third company, Durham-based R65 Labs. The company is focused on digital health solutions that drive individual and group performance.
