Understanding the Human Brain and Disease

Genetic approaches and next-generation 3D human brain models to decode pediatric neurological disease.

About the Lab

Decoding the genetic basis of brain disorders

The Chen Lab investigates the genetic mechanisms underlying pediatric neurodevelopmental disorders. Building on advances in multi-level in vitro and in vivo 3D cellular systems, we aim to investigate how disease-causing variants alter gene networks, cellular states, and circuit-level phenotypes in the developing human brain.

Research Focus

Our scientific questions

We use human iPSC-derived neurons, brain organoids, and mouse models to study how genetic variants cause pediatric neurological disease.

01

Neurodevelopmental Disorders

Investigating the genetic underpinnings of autism spectrum disorder, intellectual disability, and epilepsy using patient-derived iPSC models and CRISPR genome editing.

ASD Epilepsy iPSC CRISPR
02

3D Brain Organoid Models

Developing next-generation cerebral organoid systems to model human brain development and disease in a dish, enabling high-throughput functional assays.

03

RNA Splicing & Gene Networks

Decoding how disease-causing variants disrupt RNA splicing networks and alter gene expression programs during human neurodevelopment.

06

Therapeutic Strategies

Translating mechanistic insights into therapeutic approaches, including antisense oligonucleotides, gene therapy vectors, and small molecule screens.
