Henrique Dantas came to Oregon State from Brazil to work with professor John Matthews on his signal processing research that seeks to understand how the human brain controls the trajectory of hand movements. They envision the day when people with disabilities can control a wheelchair simply by thinking.
“We are trying to unpack the complex decisions in the brain that move a hand,” Dantas said. He and his team are using electrodes implanted near the brain to gather data and analyze it to predict hand position. Dantas’ career goal is to work at Google or Microsoft on machine learning and artificial intelligence.
Anahita Sanandaji, a doctoral candidate from Iran, is looking at ways her research can improve 3-D image segmentation, which is used in applications such as CT scans.
Although automatic algorithms exist, they are not currently as accurate as a visual review by a human being, which is extremely time-consuming.
“So we are observing human experts — using videotape, eye tracking, audio recordings, and more — to see how the mind works and how their behaviors can improve the algorithms,” Sanandaji said.
