BCI Buddy
Published:
A UCSD The Basement incubator startup created by my research assistant Cassia Rizq, Gavin Roberts, and myself. Our goal was to create the neuroengineers of tomorrow via interactive projects. Users could collect their own neural data, and program their own custom brain-computer interfaces with a simple drag-and-drop Scratch-like interface. We won 3rd in a pitch competition, and succesfully piloted our product with dozens of children, and had many pre-order requests. Our company was put on pause when various members of our team had to move from San Diego.

Set Size Effects on the P3b in a BCI Speller
Published in Proceedings of the Annual Meeting of the Cognitive Science Society, 2022
While analyzing data from a BCI speller, I noticed that my classifier did not perform equally well for different target letter complexities. After verifying the classifier was fine, I began looking at the neural data, and found that the complexity (set size) of the target letter produces monotonically decreasing P3b amplitude proportional to set size.
Development and Characterization of Zinc Dry Electrodes for Wearable Electrophysiology
Published in Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2024
I often have undergraduate students fabricate EEG/EMG electrodes out of sanded pennies, which are mostly zinc. A few of these students were curious to quantify how good zinc was as an electrode. Preliminary results indicate that zinc might perform as well as some silver chloride electrodes.
Comparing Simultaneous Scalp EEG Recordings from the OpenBCI Cyton and Brain Products BrainAmp
Published in Sensors, 2026
We simultaneously recorded data from 8 EEG channels to the low-cost ($1,250) OpenBCI Cyton, and high-cost (>$30,000) Brain Products BrainAmp. Participants completed three standard ERP paradigms. Our signal comparisons show that the Cyton is able to record data with the same fidelity as the BrainAmp, and may even have lower variance.
