In pandemic's wake, EE supports unprecedented number of research internships

For undergraduates in the engineering school, summer often means a chance to apply their learning in new ways, whether conducting field research, working in industry or volunteering abroad. Last summer, with the COVID-19 pandemic disrupting many of these plans, some students’ research projects took them in unexpected directions.

In response to increased need, the Department of Electrical Engineering boosted their support for faculty-advised summer research projects. Students explored topics including strategies for making public spaces safer, techniques for make smart phones safer, and approaches for improving the building blocks of quantum computing, among others.

Musab Almajnouni and Vincent Yang: Could LEDs Aid the Fight Against COVID?

Musab Almajnouni didn't have a back-up plan for summer. He was joining a team of biologists in Madagascar, where he would use his computational skills to study disease. So, when the coronavirus pandemic swept those plans aside, forcing him home to Riyadh, Saudi Arabia, he had no idea what would come next.

That's when he got an email from his mentor, Claire Gmachl, the Eugene Higgins Professor of Electrical Engineering. She had an idea for a project that she wanted undergraduate students to lead, and reached out to Almajnouni to gauge his interest.

"I just want to state this, and I'll probably repeat it, but she's a fantastic professor," Almajnouni said of Gmachl. He first got to know her in a first-year engineering course, which sparked enough interest for him to turn from finance to electrical engineering. "She's always made herself available for students to really get to know the material she's teaching."

With that rapport established, the following summer he interned in the Gmachl lab on a biomedical sensing project, where he learned up close the ins and outs of optics research and developed strong relationships with his colleagues.

But this next project was something different. Almajnouni teamed up with his fellow junior in electrical engineering, Vincent Yang, whose plans to intern at BAE Systems had also fallen through due to the pandemic. They would work directly under Gmachl on a project to understand how ultraviolet light emitting diodes might be used to disinfect public spaces. It wasn't a trip to Madagascar or a defense security clearance, but it seemed like a golden opportunity for the two students to put their skills to use in the fight against the very disease that had crashed their plans.

"What caught my eye specifically was the application of our research topic to COVID-19," Yang said. "Given than I lost my expected summer job to COVID, and recognizing the massive impact on people around the world, I was motivated to contribute."

Over the summer, the two Slacked and Zoomed their way through a mountain of literature on the subject. In addition to regular lab group meetings, twice a week Almajnouni and Yang met online with Gmachl to parse their questions and find the essential thread to move ever deeper into the subject. After a preliminary review, they began developing a model for more efficient UV-emitting devices.

"Musab and Vincent were such amazing researchers," Gmachl said. "They always were a step ahead of me in exploring and evaluating various device geometries."

This project was one of six funded by the Stephen C. Johnson Slingshot Fund for Innovation, an unprecedented effort by electrical engineering to support faculty-advised summer research for its undergraduate students.

Yang took the lead in working out the optical simulations through a computer modeling tool, adjusting the geometries by a few nanometers at a time until the numbers matched their needs, which Almajnouni helped define through his research of the materials. By summer's end, they had identified a wavelength of ultraviolet light that shows evidence of being both safe and effective for public spaces. This fall they are continuing the work as independent research, with a goal of drawing their analysis toward the design of a useful device. The team believes LEDs could one day transform the health and safety of public spaces. But the research is far from conclusive.

"The next step is to just write a paper and try to publish it and see where it takes the scientific community," Almajnouni said.
