I work at the Barrow Neurological Institute in Phoenix, AZ, where I run the Brain Modeling Laboratory. My primary research interests are using single neuron recording in human epilepsy patients to study cognitive neuroscience.
In my thesis work with Prof. Raimond Winslow I studied how molecular noise sources present in the photoreceptors of the retina limit the ability to detect flashes of light. This work combined electrophysiological measurements in the tiger salamander retina with computer modeling and signal detection theory. Primary coursework included:
My primary studies were in biophysics with an emphasis on mathematics and computer modeling.
In 2008, I established the laboratory with a focus on human single neuron recording in epilepsy patients. Our major discoveries have included a representation of race amongst neurons in the left amygdala, the effects of low-level image properties, such as image brightness and contrast, on neurons in the medial temporal lobe, and a method for determining where seizures are likely to originate based on single neuron recordings.
Established research collaborations with epileptologists at the Barrow Neurological Institute and developed courses on biomedical engineering and signal processing.
As a faculty member of a young department, I developed the core course on biomedical signal processing while collaborating with the University of California, Los Angeles on performing real-time control of single neuron firing in human epilepsy patients.
My research in the laboratory of Christof Koch focused primarily on understanding how noise sources in cortical pyramidal cells influenced signal processing in the cortex. In this work we used a combination of stochastic ion channel models and multi-compartmental neuronal modeling.
My research in the laboratories of Ernst Niebur and Kenneth Johnson showed that synchronous firing of neurons in the second somatosensory area was related to the attention devoted to a tactile, versus a visual, stimulus. This work used Monte-Carlo simulation to show the statistical significance of these differences recorded in the Macaque monkey.
I co-founded this company which employed 10 people. We worked primarily on the design and development of microprocessor based controllers as well as business database systems using the Macintosh platform.
