FAA COE Student of the Year – Zach Grasley
Zachary Grasley has been named the 2005 DOT COE Student of the Year. Zach is a Ph.D. student with CEAT in the University of Illinois’s Department of Civil and Environmental Engineering. He completed his Master’s in Civil Engineering at the University of Illinois in 2003 under faculty advisor and CEAT Director, David Lange. Professor Lange is also his advisor for the Ph.D. work which he is expected to defend in June 2006. Zach completed his B.S. in Civil Engineering at Michigan Technology University in 2001, graduating Summa Cum Laude.
The Award
For the past fifteen years, the U.S. Department of Transportation (DOT) has honored an outstanding student from each University Transportation Center (UTC) at a special ceremony held during the TRB Annual Meeting, and FAA has been invited for the past six years to submit a nomination. Zach is the fourth student from the University of Illinois to receive this award. As the Outstanding Student of the Year, Zach will receive a certificate presented by a high-ranking Departmental official. In addition to the certificate, Zach will receive $1,000 through an award from the Center, plus the cost of attendance at TRB. Selection for the award was based upon his accomplishments in three areas: Technical Merit and Research, Academic Performance; and Professionalism and Leadership.
His Research
Zach has been involved in several research projects while pursing his Master’s and Ph.D. degrees at the University of Illinois and with CEAT. Zach’s research during his Ph.D. studies has been focused on PCC Mix Designs, August 2004- June 2006. This research project involves assisting in the optimization of concrete mixture design specifications for a new airfield pavement at O’Hare International Airport and assessing the feasibility of using recycled concrete aggregate as an internal curing agent in new airfield pavement. Zach has also received an Eisenhower Fellowship Research award through the National Highway Institute for developing new analytical models for predicting shrinkage of concrete as both a composite and viscoelastic material in which he authored the grant proposal. In addition, Zach won a PCA Research Fellowship in support of his work on the project New Sensor Tech. to Measure Int. Moisture Content in Concrete.
