Hey there. I'm a neurosciences Ph.D. candidate in the lab of Prof. Eric Halgren at UC San Diego. My research is mainly
focused on the structure and function of the hominin cortex, perhaps the most complex object in the universe. I examine the structural connections that underpin corticocortical communication using diffusion MRI
and the functional correlativity that is its hallmark by compositing spontaneous activity from intracranial depth electrode recordings in hundreds of patients
with drug-resistant epilepsy. My hope is that a better understanding of the full map of cortical communication can be leveraged to improve non-invasive
neuroimaging technologies like EEG and MEG.
In addition to my primary lines of inquiry, I have some tangentially-related projects looking at the transcriptional markers of evolutionarily-recent cortical expansion and
producing synthetic M/EEG, as well as an older series of work investigating acute alcohol intoxication and executive function with MEG. More broadly, I'm
interested in data-driven approaches to observing the human brain's structure and function as it exists in its natural environment.
I'll be graduating soon and will then begin post-doctoral training with Profs. David Van Essen and Matthew Glasser at Washington University.
