Projects
Neurodevelopment Initiative
Elucidating the development of the infant’s brain structure & function.
NeuroPlant Initiative
The NeuroPlant Initiative aims to leverage a botanical armamentarium to manipulate the brain — by building a pipeline to explore chemicals synthesized in plants as potential new treatments for neurological disease and as a window into the chemistry of the brain.
Nanoscale to circuit-level computational and experimental studies of the biophysical mechanism of ultrasound-mediated mechanical neurostimulation
Although ultrasonic neurostimulation has the potential to outperform traditional treatments for many debilitating neurological disorders, it remains unclear how ultrasound affects nervous system activity on the molecular level.
Elucidating mechanisms of microglial tiling
In a process called tiling, homeostatic microglia homogenously organize in a grid-like fashion to achieve efficient surveillance of the brain. The molecular mechanisms underlying tiling are unknown. I hypothesize that microglia use cell-surface proteins to sense density of neighboring microglia, thereby contributing to constant cell-to-cell distances.
Design and development of a high-performance intra-cortical speech BCI
Many neurological injuries and diseases such as brainstem stroke and Amyotrophic Lateral Sclerosis (ALS) result in severe speech impairment, drastically reducing quality of life. Recent progress in brain-computer interfaces (BCI) has allowed these individuals to communicate, but performance is still far lower than typical spoken conversation speeds.
Elucidating the biophysical mechanisms of latrophilin activation in excitatory synapse formation
Mapping the Mitophagy Network in Parkinson’s Disease
We will comprehensively define the gene network associated with mitochondrial dysfunction in Parkinson's disease using a cutting-edge technology, CRISPR, to understand how these nerve cells die in PD and how we can reverse the cell death to treat the disease.
Inflammation, Major Histocompatibility Class I and human brain development
Maternal infection is linked to increased risk of neurodevelopmental disorders such as autism and schizophrenia. This proposal examines how virus-associated cytokines, specifically interferons, affect human neurons modeled in brain organoids or studied directly in fetal brain samples.
Curiosity-driven social learning and interaction in artificial agents and humans
In order to reach the level of intelligence that humans possess, artificial agents need to be able to autonomously interact with other agents and humans and build rich models of how other minds work as a result of these interactions.
Restoring multi-limb motion in people with paralysis via brain-computer interface
Intracortical brain-computer interfaces (iBCIs) can restore lost communication and motor function for people with severe speech and motor impairment due to neurological injury or disease. iBCIs measure neural activity from the brain, decode this activity into control signals, and use these signals to guide prosthetic devices such as computer cursors and prosthetic arms.
Assessing the generalizability of individual brain models
Cognitive neuroscience has traditionally focused on identifying the neural basis of psychological traits or state effects across large samples of participants. Recently, researchers have pushed towards providing more precise estimates of individual functional organization to better understand both psychological constructs as well as their supporting neural mechanisms.
Next-generation brain imaging in freely moving animals
Calcium imaging in freely behaving animals allows for the tracking of neuronal activity under approximately normal behavioral conditions. However, the slow response time of calcium imaging inhibits high resolution voltage and temporal measurements. To address this issue, modern molecular tools have been developed to optically report the high-speed dynamics of neurons more accurately.
Optogenetic screening of the gut-brain axis via an internal light source
The gut-brain axis is implicated in many essential physiological and psychological functions, ranging from feeding, emotion, motivation, to memory. As a critical component of the gut-brain axis, vagal sensory neurons exhibit distinct projection patterns to target specific visceral organs.
Structural analysis of chloride channel CLC-2
Membrane transport proteins are essential for life. They transport essential nutrients and minerals across the membrane barrier that surrounds each cell in the human body. This transport is necessary for every living process – from eating and breathing to learning and doing daily work.
Topical Hedgehog modulators to enhance motor nerve regeneration after injury and repair
Development and validation of selective novel small molecule therapeutics for Parkinson's Disease
Extended Reality(XR) enhanced behavioral activation for treatment of Major Depressive Disorder
This team has created an extended reality–enhanced implementation of "behavioral activation," one of the most effective forms of evidence-based psychotherapy for major depression. They will use the Neuroscience:Translate award to test the efficacy and scalability of this approach and accelerate the development of extended reality technologies to improve treatment options for major depression.
Autism digital therapy with embedded endpoints and artificial intelligence for progress tracking and adaptive care - Renewal
Development of an extracochlear neurostimulation device to restore hearing – Renewal
Sensorineural hearing loss is an increasingly prevalent condition that causes disability to over a third of US adults aged over 65. This team is developing a breakthrough device to restore high-frequency hearing that preserves residual hearing through a reversible and minimally invasive approach.
Remote reliable measurements of movement using bluetooth enabled engineered keyboard for diagnosis of neurological diseases - Renewal
This team is developing a device that will enable accurate diagnosis of Parkinson’s disease via telemedicine. They initially introduced the technology of Quantitative DigitoGraphy (QDG) using a repetitive alternating finger tapping (RAFT) task on a musical instrument digital interface (MIDI) keyboard and will use Neuroscience: Translate funding for the next stage of device development.
Leveraging screenomics to identify mental illness: Detecting bipolar disorder through computational analysis of smartphone screen data
Mental illnesses like bipolar disorder affect millions of people around the world, but early symptoms are often difficult to detect. Working across the disciplines of clinical psychology, communication, and computer science, my research will develop a novel computational tool to identify signals of mania and depression in real-time.
Optimizing computational modeling of traumatic brain injury with machine learning: biomechanics and beyond
Traumatic brain injury (TBI) has become a global health hazard. If undetected, the brain damage of TBI can accumulate, calling for better TBI modeling and warning systems. TBI modeling involves three stages: head impact kinematics, brain deformation, and injuries.
Mechanistic insights into glycerophospholipid metabolism in the lysosome
Phospholipid dysregulation is implicated in the pathogenesis of lysosomal storage disorders (LSDs). We found that glycerophosphodiesters (GPDs) accumulate in lysosomes derived from Batten disease models, a life-limiting LSD whose pathological mechanism remains elusive. GPDs are the degradation products of glycerophospholipid catabolism by phospholipases.
