Fatma Deniz (born Imamoglu)


I am a postdoctoral researcher in the Gallant lab in UC Berkeley
and a Data Science Fellow at Berkeley Institute for Data Science.
I was also a DAAD FitWeltweit fellow at the
International Computer Science Institute.



Research interest

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.
