Summer scholar profile: Grace Aro

Each year, the Summer Scholars Program awards funding to a select group of rising juniors and seniors from across Tufts academic disciplines, to carry out ten-week independent research projects. This summer, we profiled three engineering students as they worked on their projects.

Project: There are “a lot of people in the world who don’t have access to clean drinking water,” says Aro, “and that’s a big issue.” Her project investigates an interesting potential solution: a co-polymer membrane that could filter organic materials out of surface water, while resisting getting clogged. The membranes that she made and tested in the lab are zwitterionic, meaning that they were created with zwitterions — ions that have positive charges on one end and negative on the other.  So far, Aro’s research suggests that the zwitterionic membranes seem to have equal the filtering capabilities of commercially-sold membranes, while clogging less. She’s also experimenting with whether the membranes can remove lead from a solution.
