"It's a fantastic and unique acquisition for our university," said cell biologist Claire Walczak, the Imaging Center's executive director. "This super-resolution microscope, one of only 16 in the world and one of only 8 commercial units, is part of our vision to bring state-of-the-art technology to IU's life science researchers, to enable them to address questions that they did not have the ability to ask previously, due to the lack of appropriate technologies."
