Biography:
Nathan obtained his BA in Biological Anthropology and
Psychology at the University of Santa Cruz.
He later worked as a research assistant at the VA hospital in San
Francisco investigating the diagnostic markers and disease progression
of various forms of neurodegenerative disease using MRI and NMR
spectroscopy. During this time, Nathan also collaborated with the
Marine Mammal Center in Marin to help implement MRI techniques for
studying Sea Lions suffering from brain damage due to water pollution
in the San Francisco bay. He also worked for the Farallones National
Marine Sanctuary tracking Harbor Seal behavior and population
demographics along the West coast. During that summer, Nathan spent
three months at the La Suerte Biological Field Station in Costa Rica
where he conducted an independent field study investigating the vocal
patterns of free-range Capuchin Monkeys (Cebus capucinus).
In 2006 Nathan was awarded the Brain Research Scholarship to purse a
PhD degree at University College London. During his time at the
Institute of Neurology and at the Institute of Cognitive Neuroscience
in Queen Square, Nathan worked closely with epilepsy patients suffering
from bilateral hippocampal sclerosis (BHS). Specifically, his team
investigated deficits of short-term working memory due to hippocampal
damage (BHS) using Magnetoencephalography recordings of induced
cortical oscillatory activity. These studies led to a systematic
exploration of the anatomical and functional interactions between
long-term and short-term forms of memory.
Research Description:
Nathan’s research currently focuses on
the characterization of individual’s perceptual abilities and
how these processes interact with higher cognitive functions, such as
working memory and interference suppression. Using methods such as
electroencephalography (EEG) and functional magnetic resonance imaging
(fMRI), Nathan aims to elucidate the neural correlates of these
processes and determine how the cortical networks supporting such
abilities are modified over the course of normal ageing.
