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.

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.

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.

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.

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.

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.

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.

This team aims to advance augmentative and alternative communication technology for people with communication disorders and enable new forms of human-computer interaction by combining novel materials science with modern machine learning.

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.
