Armour College of Engineering Undergrads Busy with Fall Armour R&D Projects

Armour_Logo_Website.jpgTwenty-five Armour College of Engineering (ACE) undergraduate students were awarded funds to participate in the Fall 2014 Armour R&D Program. This competitive program offers undergraduate engineering students the opportunity to gain a more complete understanding of the research and development process, preparing them for further success after graduation. Students are selected to participate in the program based on merit and are sponsored through Armour College of Engineering, IIT Wanger Institute for Sustainable Energy Research (WISER), Pritzker Institute of Biomedical Science and Engineering at IIT, and IIT Institute for Food Safety and Health (IFSH). Half of the funded students were newcomers, while the other half were returning to the program to further their research and development.

Armour R&D includes the Program for Undergraduate Research Education (PURE) and Mentored INovation and Development (MIND). Students selected to participate in PURE will have an opportunity to team with an IIT Faculty mentor on an engineering research project and gain valuable research experience. Those selected under the MIND program will develop technology based on research findings. Students will explore new applications of ongoing research and/or work towards the utilization of innovative technology.

The projects are categorized under the four IIT Engineering Themes: Water, Health, Energy, and Security. These themes are areas in which engineers can generate solutions of global impact that advance society.
