Maryana Alegro Ribeiro, PhD

Postdoctoral Fellow
Neurology
Fields of Interest: 

Dr. Alegro joined the Grinberg lab in 2015, where she uses her knowledge in image and signal processing for building computational tools to help improve the understanding of neurodegenerative diseases. She also works in building and testing prototype imaging equipment for the lab. Her major experience is in MRI and histological image processing and, more recently, polarized light imaging. Dr. Alegro received her MSc in electrical engineering from the University of São Paulo Polytechnic School in 2009, where she focused on MRI brain tumor segmentation using machine learning. In 2014 she completed her PhD degree at the University of São Paulo Polytechnic School, her research focused on MRI and histology image registration. Dr. Alegro also has a long experience as enterprise software developer, having worked on the development of several medical systems for the Brazilian government.
