News  

Our new abstract will be presented at SfN: Fortin N.J., Elias G.A., Li L., Agostinelli F., Baldi P., Shahbaba B. (2018), Sequential activation of upcoming nonspatial item representations in hippocampal activity, Society for Neuroscience Abstract (San Diego, CA).


We received an NIH grant (R01MH115697) to develop novel methods for neural data analysis. This is a collaboration with Dr. Hernando Ombao and Dr. Norbert Fortin.


I will be presenting at the 9th International Purdue Symposium on statistics


I will give a talk at the Kyoto Deep Learning workshop on March 19.


Our new paper on dynamic modeling of covariance matrices is available on arXiv. You can also see a demo here.
