Welcome to my new and improved home
page!
I am a Ph.D. student in the
department of Psychology at Arizona State University. My research
interests include memory and language representation, neural network
modeling, effects of ageing and Alzheimer's disease, and multivariate
analysis methods for fMRI.
I am currently conducting my dissertation research at NIH.
I am pursuing the application of large-scale neurobiologically realistic models to the problem
of multi-modal information integration (including prior experience) mediated through top-down and bottom-up
attention. Specifically, I am developing a model of selective and divided attention during delayed-match-to-sample
and paired associates tasks. A large amount of data exists in the literature on this topic, at many different spatio-temporal
levels of analysis including single cell recordings in animals, EEG and MEG, fMRI, PET, and behavioral measures.
Large-scale neurobiologically realistic models are an attempt to combine these multiple levels of analysis to
inform a single theory; in this case of multi-modal integration.
My Masters thesis examined a new
perspective on evaluating computational simulations and variables in
written word recognition. Evaluating popular models of word recognition
suggests that we may need to rethink the simplistic view of orthography to
phonology conversion and its role in word recognition. Multivariate
analysis of several phonology variables from a novel experiment also leads
to the same conclusion.
