RESTORE congratulates the successful completion of three undergraduate summer NSERC research students
Adam Papini (Chemical Engineering), Laura Kinsman (Civil and Environmental Engineering and Cooper Robinson (Integrated Engineering) undertook summer NSERC research scholarships within RESTORE in the period May - August 2008. They investigated aspects of bioremediation processes, contaminant behaviour in non-ideal systems, and nanoparticle transport in the subsurface. Regarding the experience, Laura says, "It was a very rewarding and challenging opportunity to have been involved with RESTORE. The experience gained and the new friends I met made for a great and memorable summer!" While they return to undergraduate classes in the fall, all have been invited to continue their research and remain part of the group into the future.
