Ph.D. Candidate Alfredo Vidal Ceballos Creates Microscopic Images to Increase Awareness of Diseases Like Alzheimer’s Alfredo Vidal Ceballos s, a Ph.D. candidate in biochemistry, works in Professor Shana Elbaum-Garfinkle’s lab at the Advanced Science Research Center at The Graduate Center, where he researches the role that material properties, such as viscosity and surface tension, play in regulating biomolecular liquids in the brain. Vidal Ceballos is also a Creative GC: Art Science Connect Research Fellow. The fellowship supports his project to create compelling microscopic images that increase understanding of what a disease like Alzheimer’s actually does to the brain. He recently spoke to The Graduate Center about his work and his academic career at CUNY, which began in 2012 when he moved from Mexico to enroll at Hunter College.
