This article reports that a Virginia Tech professor whose wife was among 32 people killed by a student gunman last year will become director of the university's new Center for Peace Studies and Violence Prevention. Jerzy Nowak will give up his job as chairman of Tech's horticulture department to take the new post on July 1. His wife, Jocelyne Couture-Nowak, was a instructor of French whose classroom sustained the most casualties--12 killed and six injured--in the rampage by Seung-Hui Cho, a mentally ill undergraduate. Mr. Nowak, who is 61, led the effort to create the new center following the tragedy. The center will have research and community-outreach components, and it will involve a range of people, from students to faculty members to politicians to community leaders. It will span the applied sciences and the humanities, bringing teams of people together to talk about and carry out violence-prevention strategies. In his new job, Mr. Nowak will bring together people from a variety of fields, something he did in the horticulture department, working with industry and politicians on community development and economic diversification. Furthermore, Frederick A. Winter, a senior program officer at the National Endowment for the Humanities, has been appointed senior director of advancement and leadership development at the Association of American Colleges and Universities. Starting in July, Mr. Winter will oversee the association's Liberal Education and America's Promise, or LEAP, campaign, which was started in 2005 to promote liberal education. In his new position, he will manage fund raising for the campaign, develop its leadership, and drum up support for liberal education among business and philanthropic leaders.
