BRIEF BIO

I’m a postdoctoral research fellow working with Prof. Daniel Polley at the Eaton-Peabody Laboratories (Massachusetts Eye and Ear Infirmary) and Department of Otolaryngology (Harvard Medical School).

In 2012, I received my PhD from University College London, where I worked at the Gatsby Computational Neuroscience Unit with Maneesh Sahani and Jennifer Linden.


RESEARCH INTERESTS

Broadly, I’m interested in systems-level neuroscience of the auditory system. My current research is focussed on addressing neural coding questions within the mouse auditory system, with a focus on understanding the role of corticofugal projections in perception of the sensory environment. I also have an active interest in computational neuroscience and the statistical aspects of neural data analysis.
