Kwasa works in the labs of Pulkit Grover, Angel Jordan Professor of Electrical and Computer Engineering and the Neuroscience Institute and Barbara Shinn-Cunningham, director of the Neuroscience Institute and George A. and Helen Dunham Cowan Professor of Auditory Neuroscience. Kwasa is also the chief technology officer of Precision Neuroscopics, a startup that sells inclusive neural technology products.
Precision Neuroscopics wins $150,000 UpPrize for improving EEGs for Black patients
Pulkit Grover, a co-founder and chief visionary officer at Precision Neuroscopics and professor of electrical engineering at CMU, says Etienne’s discovery of the problem with EEGs “was equally as important as finding the solution.”
Why Companies Are Using AI to Increase Diversity, But It May Not Work
"The biggest issue is that AI systems are great at observing and identifying patterns, which can propagate biases with respect to gender, race, etc. present in historical data, or even generate entirely new biases not present in the data," Pulkit Grover, a professor in the Department of Electrical and Computer Engineering at Carnegie Mellon University, who was not involved in the research, told Lifewire in an email interview.

This is a three-year study to develop a novel system for concussion monitoring and treatment. The proposed work brings together scientific leaders in engineering, neuroscience, and clinicians in brain injury research at CMU and University of Pittsburgh to develop automated noninvasive monitoring and treatment of concussions.
Innovation in brain imaging
Writers and scientists throughout history have searched for an apt technological analogy for the human brain, often comparing it to a computer. For Pulkit Grover, Carnegie Mellon University assistant professor of electrical and computer engineering and the Center for Neural Basis of Cognition, this analogy couldn't be more fitting. Although Grover and his research team spend much of their time exploring how information flows through computer networks (such as coding systems, cyberphysical systems, and low-power wireless systems), they also apply these information theory principles to brain-imaging systems. This cross-disciplinary research approach bridges mathematical theory with clinical applications—striving to improve the treatment of neurological disorders such as epilepsy.

Method for detecting and localizing brain silences using eeg
A novel method for using the widely-used electroencephalography (EEG) systems to detect and localize silences in the brain is disclosed. The method detects the absence of electrophysiological signals, or neural silences, using noninvasive scalp electroencephalography (EEG) signals. This method can also be used for reduced activity localization, activity level mapping throughout the brain, as well as mapping activity levels in different frequency bands. By accounting for the contributions of different sources to the power of the recorded signals, and using a hemispheric baseline approach and a convex spectral clustering framework, the method permits rapid detection and localization of regions of silence in the brain using a relatively small amount of EEG data.
Non-invasive method for suppressing spreading depolarization in human brains
Methods providing reliable and non-invasive ways to suppress spreading depolarization waves leading to cortical spreading depression are disclosed. The calcium conductance parameter of the 6 component Tuckwell model of spreading depolarization wave propagation is modified using Anderson Localization and other methods to disrupt the propagation of the waves, thus suppressing and eliminating spreading depolarization.
Conductive carbon fiber-based sponge
A carbon fiber-based conductive sponge for low electrode-skin impedance biosignal recordings is described. When the sponge is used with water or saline solution, no gel is required, drastically lowering the setup time for EEGs compared to classical wet electrodes. The wet sponges achieve an electrode-skin impedance as low as 2.5 kΩ¶ when wet, making them better than state of the art gel electrodes. Additionally, even as the sponge dries, it continues to remain conductive and performs as a reliable dry electrode.
A model of neurovascular coupling and its application to cortical spreading depolarizationJournal of Theoretical Biology
2023 Cortical spreading depolarization (CSD) is a neuropathological condition involving propagating waves of neuronal silence, and is related to multiple diseases, such as migraine aura, traumatic brain injury (TBI), stroke, and cardiac arrest, as well as poor outcome of patients. While CSDs of different severity share similar roots on the ion exchange level, they can lead to different vascular responses (namely spreading hyperemia and spreading ischemia).
High resolution focused non-invasive electrical stimulation of motor cortex in rodent model2023 11th International IEEE/EMBS Conference on Neural Engineering (NER)
2023 Transcranial electrical stimulation (TES), a technique for stimulating the brain without surgical intervention, has potential applications for therapeutic interventions as well as brain-computer interfaces. One of the known limitations of conventional TES is that the stimulation volume is very large, due to the size and placement of electrodes typically used, which does not allow accurate targeting and results in large off-target activation. This work demonstrates a novel method for high resolution transcranial stimulation of motor cortex in mouse models using a flexible ultra-high-density electrode array.
Building a culture of responsible neurotech: Neuroethics as socio-technical challengesNeuron
2022 Scientists around the globe are joining the race to achieve engineering feats to read, write, modulate, and interface with the human brain in a broadening continuum of invasive to non-invasive ways. The expansive implications of neurotechnology for our conception of health, mind, decision-making, and behavior has raised social and ethical considerations that are inextricable from progress.
Effect of skull thickness and conductivity on current propagation for noninvasively injected currentsJournal of Neural Engineering
2021 When currents are injected into the scalp, e.g. during transcranial current stimulation, the resulting currents generated in the brain are substantially affected by the changes in conductivity and geometry of intermediate tissue. In this work, we introduce the concept of 'skull-transparent' currents, for which the changing conductivity does not significantly alter the field while propagating through the head.
Abnormalities in cortical pattern of coherence in migraine detected using ultra high-density EEGBrain Communications
2021 Individuals with migraine generally experience photophobia and/or phonophobia during and between migraine attacks. Many different mechanisms have been postulated to explain these migraine phenomena including abnormal patterns of connectivity across the cortex. The results, however, remain contradictory and there is no clear consensus on the nature of the cortical abnormalities in migraine.
