The 2021 Great Lakes Regional Conference for the Institute of Industrial and Systems Engineers, hosted at Purdue University, will be focused on Hidden IE: Systems are Everywhere. Industrial and systems engineers are known for expanding into a variety of industries. During this interactive weekend, we will explore and build upon the problem-solving and communication skills that ISE programs teach and learn how our daily interactions can align with our unique passions. Systems are present everywhere, from coordinating college football games to improving the admission process in hospitals, and everything in between. Purdue’s chapter of IISE is excited to host a diverse group of speakers, industry partners, and students with the goal of strengthening networks and stretching the perception of typical roles for industrial and systems engineers.
