Nathan defended his doctoral disseratation in March 2009 and is currently working at The Genome Institute at Washington University School of Medicine.
In addition to studies of neural synchronization in BOLD-fMRI imaging, Nathan's thesis reserach involved the development of computational models of species evolution and optimal animal foraging behavior. His papers on foraging and evolution include:
