Hey there. I'm a neurosciences post-doc in the lab of Profs. David van Essen and Mathew Glasser at Washington University in St. Louis. My current research is mainly focused on quantitatively evaluating inter-species and interareal homology between regions of the cortex. My doctoral thesis was on structural and functional connectivity of the human cortex, as examined with diffusion MRI and intra-cranial depth electrode recordings in patients with drug-resistant epilepsy. My advisor was Prof. Eric Halgren at UC San Diego. 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 structure, function, and evolution of human cortex.

Fun Facts

• The weakly electric elephantnose fish has the largest brain-to-body oxygen use ratio of all vertebrates. I tried to keep one in the lab aquarium, but was unsuccessful.
• A primitive EEG system can be cobbled together from an Arduino and $35 mattel toy.
• I've been to all 58 of my home state of California's counties.
• According to Neurotree, there are 88 generations of mentor-mentee relationships in the direct line of decent from John the Baptist to me. Notable links in the chain include Charles Sherrington and Albertus Magnus. If I have seen further it is by standing on the shoulders of giants.
