Uncertainty in Experimental Measurements (and Other Lessons from the Real World)

Release Date:
9/20/2013 9:00 AM

Gregory Quinn, features Gregory Quinn


The Alvine Engineering Professional Effectiveness and Enrichment Program will present a lecture by Dr. Gregory Quinn. He will introduce the concept of measurement uncertainty as it relates to engineering testing and experiments.  Understanding uncertainty and other concepts related to good experimental practice enables engineers to set up better tests, understand the limitations of the data they gather, and critically examine the claims of other researchers. Every means of measuring the physical world has some degree of uncertainty to it, whether it’s using a yard stick or a scanning electron microscope, and there are accepted means to ascertain, calculate and present uncertainty from those measurements.  Additional lessons learned about research engineering and personal experimental mishaps will be shared.


Dr. Quinn graduated as valedictorian in 2000 from the Stevens Institute of Technology with a BE and ME in mechanical engineering.  Upon graduation he accepted a position as a research engineer at Hamilton Sundstrand Space Systems International where he has enjoyed developing space technologies ever since.  Dr. Quinn also received a Ph.D. in mechanical engineering from the University of Connecticut in 2009. His work at Hamilton Sundstrand has focused on spacecraft thermal control systems and technology as well as advanced space suit life support systems.  In 2005, he traveled to the high arctic of Canada for the Haughton Mars Project, where he tested several new spacesuit concepts. Since 2011 he has been the lead thermal control systems engineer for Sierra Nevada’s Dream Chaser commercial crew vehicle, and in 2013 assumed responsibility as the technical lead for advanced space suits.

The University of New Haven is a private, top-tier comprehensive institution recognized as a national leader in experiential education. Founded in 1920 on the campus of Yale University in cooperation with Northeastern University, UNH moved to its current West Haven campus in 1960. The University operates a satellite campus in Tuscany, Italy, and offers programs at several locations throughout Connecticut and in New Mexico and California. UNH provides its students with a unique combination of a solid liberal arts education and real-world, hands-on career and research opportunities. The University enrolls approximately 6,400 students, including nearly 1,800 graduate students and more than 4,600 undergraduates – the majority of whom reside in University housing. Through its College of Arts and Sciences, College of Business, Henry C. Lee College of Criminal Justice and Forensic Sciences, Tagliatela College of Engineering, and College of Lifelong & eLearning, UNH offers 75 undergraduate and graduate degree programs. UNH students have access to more than 50 study abroad programs worldwide and its student-athletes compete in 16 varsity sports in the NCAA Division II’s highly competitive Northeast-10 Conference.
