ALUMNI REGISTRATION & UPDATES The Department of Civil & Environmental Engineering is always interested in how our alumni are doing. We hope you will take the time to send your updates to [email protected] or, if you prefer, you can “snail mail” them to: Department of Civil and Environmental Engineering Louisiana State University Attn: Julie Mueller 3418 Patrick Taylor Hall Baton Rouge, LA 70803‐6405 Please include basic information such as your full name, year of graduation, degree, mailing address, email address, telephone number, company, and your title/position. For your update, please include information on your recent professional and personal developments, along with a high‐quality photo, if available. Thanks for staying in touch! Volume 15 Fall 2015 Louisiana State University 3418 Patrick Taylor Hall Baton Rouge, LA 70803‐6405 ADDRESS SERVICE REQUESTED I n October, the Department of Civil and Environmental Engineering was visited by two ABET accreditation teams. One team focused on the civil engineering undergraduate program while the other team focused on the environmental engineering undergraduate program. ABET accreditation, which the programs undergo every 6 years, is very important to the department, our students, employers of our graduates, and other constituencies. Accreditation involves a continuous improvement process, as well as documentation, which ensures our curricula in civil and environmental engineering are relevant and meet the expectations of the profession. This evaluation is an exhaustive and comprehensive process and therefore I wish to express my sincere gratitude to all of the faculty and staff who worked diligently to prepare for the visit. The accreditation teams examine a program’s curriculum, admission processes, advising procedures, assessment processes, and samples of student work. Programs must demonstrate achievement of their stated objectives and outcomes. The department is anticipating that both curricula will be accredited for the maximum six year period prior to the next mandatory accreditation visit. Along with numerous student and faculty achievements in this issue we also share with you research highlights from two of our new assistant professors: Drs. Navid Jafari and Chao Sun. Both joined our department this fall and are a welcomed addition to an already strong faculty base. Pictured above is the new renovated Patrick F. Taylor Hall that will house all the engineering departments in the College of Engineering. Completion of the building is set for November 2017 and so far the project is on schedule. 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.
