CEE held its first video competition March 14, screening 10 videos illustrating science and engineering advances that hold clues to a sustainable future. After the audience voted, official judges Professor Christopher Kaiser of biology and CEE Professor John Williams weighed the data and added their own assessments. Course 1 senior Sid Pai won first prize for a video chronicling a company he co-founded, Protoprint, that teaches waste pickers in India how to convert trash into filament for 3-D printers. A team of graduate students — Leon Dimas, Dieter Brommer, and Tristan Giesa — took second place prize for a rap video highlighting advances in their fields. Graduate student Jennifer Apell won third place for “New Samplers for Old Problems,” a video showing how to measure pollutant levels in contaminated sediment with a plastic sampler. View the videos.
