I am a Research Scientist at the Mind Research Network in Albuquerque, New Mexico. I am interested in how apparently distinct brain networks integrate and shape sensory processing. Within my research, I often isolate brain activity by measuring the cortical response to steady-state visual or auditory stimuli (i.e. with frequency-tagging). These studies have revealed distinct attention networks for enhancement and suppression (Psych Science), individual differences in attention strategies during fine and course discriminations (Journal of Neurophysiology), individuals sensitivity to musical patterns (Frontiers), and the influence of visuospatial load on auditory 40 Hz responses (Frontiers). I am also interested in isolating brain responses that contribute to processing more natural or socially relevant stimuli. Toward this aim, we demonstrated that EEG responses to movie clips contain enough information to predict which clips individuals viewed, but did not appear related to individuals subjective preference for the clip content (PLOS ONE). In an EEG hyperscanning study, we demonstrated that EEG responses during speech preparation are related to the listener ERP response to the prepared speech (Scientific Reports). This relationship may appear as a result of each process overlapping in their sensitivity to individual effort and cortical processing.

Scientific Reports

Radio Interviews

In part 1 of an interview on KUNM 89.9 FM, Marty Adamsmith and I talk about my latest paper in Scientific Reports. In part 2 we discuss mosh pits, the whites of your eyes, how attention is the environment impinging on your brain, and whether we can find the brain measures that correspond to people "clicking".

Scientific Reports

New Paper in Scientific Reports

My latest paper came out in Scientific Reports! We show that EEG alpha activity within a speaker during speech preparation is correlated with the listener N400 ERP response to the produced speech. The relationship between listener N400 amplitudes and the speaker’s preparatory alpha activity may appear as a result of each process overlapping in their sensitivity to individual effort and cortical processing.

Brain Camp

I had a great time participating in the 2018 Summer Institute in Cognitive Neuroscience! It was three weeks with great people learning about and contributing to the next edition of the Cognitive Neuroscience textbook. (Updated 08.10.2018)

Guitar

New Paper in Frontiers in Human Neuroscience

My latest paper combines my two favorite hobbies: science and music! We showed that brain responses to individual guitar notes were modulated by musical context (key and repetition). Individuals neural sensitivity to musical patters might be related to their sensitivity to other complex processes, such as language. (Updated 02.15.2017)
