(Video: At last year's Princeton Research Day, Sara Fridovich-Keil spoke about how she could measure a person's heart rate by using a video of their face. This year, she's taken her research a step further. Come to Princeton Research Day May 10 to see her and 200 others present their findings and innovations.)
Engineering students will be well represented at Princeton’s big event for showcasing a wide array of student work and discoveries.
About 50 students from the School of Engineering and Applied Science will participate in Princeton Research Day on May 10. The day’s schedule includes student poster presentations, live talks and demonstrations. Other students will give performances and present art exhibitions. In total, roughly 200 Princeton University students are expected to participate.
Princeton Research Day is scheduled to take place at the Frist Campus Center from 10:30 a.m. to 5 p.m., and concludes with an awards ceremony. It is free and open to the public.
Among students presenting a variety of work are:
Sara Fridovich-Keil, a senior in electrical engineering, will present her technique for using video to measure blood flow in a person’s fingertips. Hemoglobin in blood, she explained, absorbs green light. With a smartphone, she can measure how much green light is reflected by a finger, which reveals information about blood flow. Fridovich-Keil is also working to use sensors in a smartphone’s camera to provide information about blood pressure, blood vessel elasticity, blood-oxygen saturation and possibly even anemia.
Nancy Lu, a graduate student in chemical and biological engineering, will present a novel system to heal cracks in structural materials, coatings and geological formations. Her team, which also includes postdoctoral researcher Jeremy Cho, believes this could lead to interesting engineering applications for the real world.
Grace Guan, a sophomore planning to study operations research and financial engineering, will give a look at the financial stability of the health care marketplaces set up by the Affordable Care Act.
And a team of mechanical and aerospace engineering students will present their research into using hybrid-electric technology in an airplane. Using battery power alone would make the plane too heavy, but they found a way to use a lighter battery in hybrid mode. They would use traditional fuel for the main flight, and battery power for when an extra boost is needed, such as takeoff and landing.
All six engineering departments are represented.
Princeton Research Day is a collaboration among the offices of the Dean of the College, the Dean of the Faculty, the Dean of the Graduate School and the Dean for Research.
