Our Mission
Systematically decode the mechanisms of brain aging and neurodegeneration, and translate that understanding into principles for rejuvenation, regeneration, and therapeutic innovation.

By integrating large-scale single-cell multi-omics, cross-layer regulatory circuitry analyses, human disease genetics and clinical informatics, and AI/ML-driven modeling, we study the genetic and epigenomic mechanisms that govern regulatory networks and intercellular communication β€” and how their disruption drives cellular vulnerability and dysfunction in aging and neurodegenerative conditions.

Direction 1 Schema
DIRECTION 1

Pinpointing the Road to Degeneration

Systems-level decoding of aging and neurodegeneration β€” defining where, which, how, and when regulation systems fail across cell populations, molecular layers, and temporal dynamics (lifetime and circadian scales).

Zunpeng Liu

Zunpeng Liu is a Research Scientist in the Manolis Kellis Lab at the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT and the Broad Institute of MIT and Harvard.

His research systematically decodes the molecular and regulatory circuitry that maintains cellular identity and investigates how its breakdown contributes to vulnerability in aging and age-related disease.

By integrating large-scale single-cell genomics, regulatory circuitry analysis, human disease genetics, clinical informatics, and AI/ML-driven modeling, he studies the mechanisms governing cell fate, tissue homeostasis, and disease-associated dysfunction, with a long-term goal of translating mechanistic insights into predictive biomarkers and therapeutic strategies.
