Projects
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.
Manipulating inflammation in the aging brain to promote brain resilience
Inflammation is a hallmark of brain aging, yet the source of inflammation in the old brain — and how to eliminate it — is unknown. This team aims to provide insight on how inflammation affects the aging brain that could potentially lead to the generation of new therapies to promote brain resilience.
Mechanistic dissection and therapeutic capture of an exercise-inducible metabolite signaling pathway for brain resilience
Exercise improves cognition and protects against age-associated neurodegenerative diseases, but further research is needed to understand exactly how this occurs. This project aims to pave the way for therapeutics that can capture the benefits of exercise for promoting brain resilience.
Mutant microglia and resilience to Alzheimer’s disease
This project aims to identify how mutant peripheral immune cells that invade the brain might actually reduce Alzheimer’s disease risk. The research will explore how to mimic these cells’ resilience-promoting effects to design new Alzheimer’s therapies.
From gut to brain: reprogramming peripheral macrophages at the intestinal barrier to prevent age-associated inflammation and cognitive decline
This team will investigate whether a decline in intestinal immune cell metabolism drives age-related inflammation and cognitive decline. By replacing aged intestinal macrophages with metabolically healthy ones, they hope to develop a novel approach to enhance cognitive resilience.
Unleashing engineered T cells as disease sensors and therapeutic actuators for neurodegenerative disease
This project will explore whether amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) result from immune cells attacking altered neurons. The team aims to pioneer the use of engineered immune cells as therapies for neurodegenerative disorders.
Role of Proteostasis and Organelle Homeostasis in Brain Resilience during Aging
This team aims to define how and why protein production breaks down in aging cells, leading to disease. This research may lead to new diagnostic and therapeutic approaches against neurodegenerative diseases and potentially aging itself.
