Welcome to our Value through Reliability, Safety, and Sustainability Lab

Arjun Rao at HeliExpo 2015

Our research is concerned with creating long-term value in systems. We use a variety of techniques, based on the problem at hand. We draw from traditional engineering, systems engineering, operations research, organizational theory, and psychology.

Undergraduate seniors with at least a 3.3 GPA are welcome to apply for undergraduate research projects. In particular, we are currently looking for a student to work on a project on system failures. Click here to learn more.

May 2014: Nicoletta Fala has won this year's Herbert F. Rogers Award. Nicoletta is from Cyprus and came to Purdue as a freshman in fall 2010 as a Fulbright Scholar through the Cyprus-America Scholarship Program. During her Purdue career she volunteered for Purdue Space Day from her freshman year and became director of the event in 2012. She was an RA for Shreve Hall for the 2012-2014 school years. Nicoletta graduated with her Bachelor’s degree on May 18th 2014 and started her Ph.D. immediately after that. Named for alumnus Herbert F. Rogers, this is one of AAE's most important awards and it is awarded to Purdue AAE senior students who are “deemed most worthy and deserving by his/her contributions to the growth of the School of Aeronautics and Astronautics in fostering engineering as an academic discipline.” AAE's Awards Committee along with two student members selected Nicoletta from among a group of talented and outstanding candidates for this award.

May 2014: Prof. Karen Marais has won AAE's Elmer F. Bruhn Award for teaching for 2014.

November 2013: Prof. Karen Marais has been awarded a CAREER grant, the National Science Foundation's most prestigious honor for young researchers. The CAREER award is intended to aid the “early career-development activities of those teacher-scholars who most effectively integrate research and education”. Prof. Marais will receive the grant for five years for the project CAREER: Accidental Knowledge: Using Accidents and other Systems Engineering Failures to Inform Research and Education in Systems Engineering".
