A data scientist and cognitive computational neuroscientist

working on understanding how the human brain works.

Welcome

Who am I?

I am a postdoctoral researcher in the Gallant lab in UC Berkeley. I am interested in how sensory information is encoded in the human brain and use machine learning approaches to fit computational models to large-scale functional neuroimaging data. Currently, using functional magnetic resonance imaging (fMRI) I try to understand how the brain represents and processes information when it performs a natural task. For example, when we listen to or read a story.

In addition, I design and promote approaches for scientific reproducibility. I co-edited a book on reproducibility published here. Here is an online version of the book. I also worked on improving online user authentication applications using image based authentication procedures combined with knowledge gained from cognitive neuroscience (Check MooneyAuth ) and created a database of two-tone Mooney images. E-mail me if you would like to use those for your research. Code is available on GitHub.

I am a passionate coder, baker, and I love feeling the resonance when I play the cello which makes me simply happy.
