When President John Peters gives presentati ons, it is Xidis who is tapped to create the PowerPoint slides and later click through them as he speaks. She makes websites fresh, att racti ve and easy to navigate, bolsters NIU’s marketi ng eff orts through constant

web upkeep for the Offi ce of Admissions and its recruitment goals. She also helped to roll out NIU’s new logo, creati ng the Graphic Standards website and bringing client websites into the new templates. Colleagues praise her respon-siveness and reliability.

Celebrating Excellence Keynote Speaker: Jaron Lanier

Wednesday, April 24, 8 p.m. 

Holmes Student Center, Duke Ellington Ball Room

Jaron Lanier, the father of virtual reality, will deliver the key-note address of NIU’s Celebrati ng Excellence observati on.

One of the most infl uenti al thinkers of our ti me, Lanier is a digital media pioneer. He not only helped popularize the term virtual reality, he also predicted many of the ways in which technology would revoluti onize and transform our culture.

In 2010, Time Magazine named him as one of the 100 most infl uenti al people in the world. He also has been named among the top 100 public intellectuals in the world by Prospect and Foreign Policy magazines as well as one of history’s greatest inventors by Encyclopedia Britannica. His new book “Who Owns the Future?” is a visionary reckoning of the eff ects network technologies have had on our economy. Lanier asserts that the rise of digital networks led our economy into recession and decimated the middle class. Now, as technology fl att ens more and more industries, from media to medicine to manufacturing, we are facing even greater challenges to employment and personal wealth. In this ambiti ous and deeply humane book, Lanier charts the path toward a new informati on economy that will stabilize the middle class and allow it to grow.

Lanier will be available to sign copies of the book following his talk.
