I t is a pleasure to introduce three new faculty members to the Department of Civil & Environmental Engineering (CEE). They have been selected to ϐill new faculty lines in the strategic initiatives of the department and the College of Engineering. Drs. Celalettin Emre Ozdemir, Hongliang Zhang, and Shengli Chen have already joined the department this fall and a fourth new faculty member will start in January 2015. The three assistant professors encompass the areas of coastal engineering, environmental engineering and geotechnical engineering, respectively. Descriptions of their research areas are highlighted in this issue of the newsletter. It is anticipated that we will hire three additional faculty members next year. Also, the department recently celebrated the debut of the ETEC Hydraulics and Water Distribution Laboratory with a ribbon cutting ceremony and reception. This lab was created to provide CEE undergraduate students an experimental and modeling facility where they can get hands‐on experience in the real‐time monitoring, control, and modeling of hydraulic systems. The department would like to sincerely thank Ronnie Hebert of ETEC, Inc. and Michael Pittman of the M.R. Pittman Group for their generous support. Another recent celebration for the College of Engineering as a whole was the ground breaking ceremony held in mid‐November for the renovation of Patrick F. Taylor Hall. This $110 million endeavor, made possible by the generous contributions of so many donors and through an impressive state match, is expected to be completed in fall 2017. This new, state‐of‐the‐art facility will provide students with an enhanced and inspirational learning environment and will serve as a superior space for innovative research. In the meantime and amidst all of the impending construction, our undergraduate programs will be preparing for our upcoming ABET accreditation visit in fall 2015. The ABET process requires that we are engaged in the continual improvement of our undergraduate programs in civil and environmental engineering and provide documentation that a process is in place to ensure such a goal is achieved. This continuous process of re‐evaluation is vital to the growth and continued success our programs. In closing, myself and the department would like to wish you and your family a wonderful holiday season. Sincerely, Dr. George Z. Voyiadjis Boyd Professor, Chair Bingham C. Stewart Distinguished Professor ALUMNI REGISTRATION & UPDATES The Department of Civil & Environmental Engineering is always interested in how our alumni are doing.
