P.h.D Candidate

Eduardo Sandoval

Eduardo is co-mentored by Robert T. Knight in the Department of Psychology and Michael DeWeese in the Redwood Center for Theoretical Neuroscience and the Department of Physics. In the Knight lab, Eduardo has been focusing on single unit activity within the anterior cingulate cortex, orbitofrontal cortex, and hippocampus during the Wisconsin Card Sorting Task and the Interval Timing Task, as well as gamma, theta, and beta oscillations in the microwire LFP.

In the DeWeese lab, Eduardo is currently developing a causal model of sparse coding for auditory nerve fibers. All of his research in the lab involves some temporal aspect, whether it be prediction of time series, or dynamical systems of the mind and brain.

Alexis Pracar

Alexis Pracar is a PhD student in cognitive neuroscience working under the supervision of Dr. Nina Dronkers and collaborating with Dr. Robert Knight. Her dissertation focuses on the neural mechanism that differentiates speech and song in patients with stroke-induced aphasia and patients with intracranial EEG. Alexis is interested in the neural architecture of language and the real time activity that supports it. She is also interested in the translation of science to wearable technologies and holds 3 issued US patents. She received her B.S. in public health from George Washington University in 2018.

Brooke Staveland

Brooke is a Ph.D. student in neuroscience working under the co-supervision of Prof. Robert Knight and Prof. Ming Hsu. Most broadly, Brooke hopes to apply computational neuroimaging methods in order to improve mental health treatment and maintenance. Her dissertation research uses intracranial EEG and computational modeling to study the neurobiology of anxiety. In her pre-doctoral work, Brooke used statistical and machine learning methods to look for meaningful treatment groups across a wide range of mental health diagnoses. Brooke received her B.S. in mathematics from George Washington University and was awarded the NSF GRFP in 2021.
