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, I use functional magnetic resonance imaging (fMRI)
and try to understand how the brain represents and processes complex information
when it performs a natural task. For example recognizing an object in an image,
understanding language, and listening to music.
In addition, I work on improving online user authentication applications using
image based authentication procedures combined with knowledge
gained from cognitive neuroscience (Check MooneyAuth for more information).
I also created a database of two-tone, Mooney images for my dissertation.
E-mail me if you would like to use those for your research. Code is available on GitHub.
