About Me

My name is Natalia (she/her) and I am an NSERC-funded postdoctoral researcher in Dr. Jennifer D. Ryan's lab at the Rotman Research Institute, Baycrest Health Sciences. I use behavioural, computational, and neuroimaging tools to reveal the cognitive and neural mechanisms that support the interplay between what we see and what we remember.I completed my PhD in Psychology in Dr. Morgan Barense's Memory & Perception Lab at the University of Toronto in 2023, after which I was a postdoctoral scholar in Dr. Maureen Ritchey's Memory Modulation Lab at Boston College in 2024.
