91视频鈥檚 Three Minute Thesis (3MT) pits doctoral students against the clock and each other to explain complex research and captivate their audience in just three minutes. Nine finalists will compete in the on Thursday, March 14, at 6 p.m., in the Tepper School of Business鈥檚 Simmons Auditorium A. A livestream will also be available.

3MT is a celebration of research that challenges Ph.D. students to present a compelling oration on their thesis and its significance in language that anyone can understand. Developed by The University of Queensland in Australia, the competition was brought to Pittsburgh by Helen and Henry Posner, Jr. Dean of Libraries in 2013. Since then, 91视频 doctoral candidates have joined students at over 900 universities across more than 85 countries worldwide in sharing their work with broad audiences through the competition.

Finalist Vishnu Raghuraman was encouraged to participate in 3MT by one of , fellow Department of Physics student Byron Daniel. In his presentation, he鈥檒l share his work writing software that can simulate real materials on an atomic level.

Raghuraman鈥檚 research specifically looks at a class of materials called multi-principal element alloys, which are amalgams containing several elements in roughly equal concentrations. These materials have many useful properties such as high strength, high durability, and low density, and they could potentially replace existing alloys such as steel.

鈥淗owever, there are billions of such alloys, making it impractical to physically make each one in a lab and test it out,鈥� Raghuraman said. 鈥淐omputer simulation is hence necessary to screen these possibilities, making our work important.鈥�

He said he feels a responsibility to be able to communicate his research with a general audience, and 3MT provides a valuable opportunity for him to practice.

鈥淎 lot of scientific work is supported by government agencies like the NSF and DOE, which means that they are funded by taxpayer dollars. I think it is the duty of scientists to explain how they have utilized that support to the taxpayers,鈥� he explained. 鈥淎dditionally, in order to keep a research field active, there has to be a healthy influx of people who want to join the field. This will only happen if the existing researchers actively market their work.鈥�

For finalist Nicole C. Auvil, effective and understandable science communication can encourage participation in science and prevent the spread of misinformation. The Mellon College of Science student, who is studying chemistry, said that explaining research in simple terms has the power to help people understand the world around them.

鈥淒oing science without being able to communicate your research is like baking a cake for a party and leaving it in the refrigerator instead of serving it,鈥� she said. 鈥淵ou wouldn't expect your partygoers to know where the kitchen is, walk to it, open the fridge, remove the cake, and cut themselves a slice 鈥� just like how we can't expect the general public to go out of their way to learn and understand science on their own. If we serve it to them pre-sliced and on a plate, maybe they'll indulge.鈥�

Auvil鈥檚 research focuses on a chemical analysis instrument known as a mass spectrometer. Typically, samples need to be prepared in a specific way for the instrument to reveal what chemicals are present in the sample. To save time and keep samples intact, Auvil helped develop an attachment that allows a mass spectrometer to act like an electronic nose 鈥� the Super Sniffer. By holding up a sample to the attachment, the mass spectrometer is able to detect chemicals emanating from it similar to the way a nose can detect chemicals in the air.

She plans to recruit friends and family to help her practice for the championship.

鈥淲hile it may not be obvious to me, the non-chemists in my life will quickly be able to identify if I haven't explained a particular topic clearly enough for anyone to understand!鈥� she said.

Finalist Benjamin Glaser broke his talk into two categories in order to effectively communicate his work: methods and materials. The student is working with an advanced material discovery model, and using it to design new aluminum alloys with high temperature strength and stability. This would make an alloy usable in applications like the pistons in an internal combustion engine or the intake fans on an aircraft鈥檚 engine.

Glaser鈥檚 goal is to create a material viable for additive manufacturing 鈥� the 3D printing of metals. This is a notoriously difficult environment, he said, as only a small fraction of all aluminum alloys are printable; and even fewer are high strength. He also wants to make an alloy with low cost and low emissions to meet sustainability goals.

Years ago, a writing class taught Glaser that if a scientist can鈥檛 communicate their research effectively, no one will be able to use it, no matter how useful the discovery is. He has channeled this lesson into his presentation.

鈥淚f I discover an approach for new material development, I need to be able to convey this method to the rest of the field,鈥� he explained. 鈥淚f I create a new high-performance alloy, I need to present how it is made and how it works, if I want it to be bought and used in industry. If I fail to do either of these, nothing I鈥檝e done will have any impact.鈥�

At the championship, 91视频 leadership and alumni judges will choose the first-, second- and third-place winners to receive $3,000, $2,000 and $1,000, respectively. Two audience-selected winners will receive $500 for the People鈥檚 Choice Award and $750 for the Alumni Award.

Alumni can watch the competition via the livestream, where they can vote to select the Alumni Award winner.

The Three Minute Thesis Championship is free of charge and open to the public. to attend the in-person event or to view the livestream.
