How does the brain control appetite and metabolic health?

engineered mouse lines

Single cell to behavior

multiscale neuroscience

NIH supported

rigorous, translational research

We combine human genetics, mouse models, circuit neuroscience and single-cell genomics to understand severe obesity and the metabolic side effects of antipsychotic drugs.

WHAT WE STUDY

Three paths toward one goal

We ask how genes, development, neural circuits and medicines interact to shape appetite and metabolic health.

Why do rare variants cause severe childhood obesity?

GENES & DEVELOPMENT 1

We define the receptors, cell types, and neural pathways that separate serotonin's beneficial effects on feeding from its harmful systemic actions

Why do antipsychotic drugs disrupt appetite control?

Which serotonin circuits suppress appetite safely?

Human genetics

CRISPR models

Single-cell multiome

We model human obesity-associated variants in mice to uncover how hypothalamic development shapes appetite, glucose control, and lifelong metabolic risks.

MC4R signaling

In vivo physiology

Metabolic phenotyping

We trace how clinically important antipsychotics alter hypothalamic signaling and use that knowledge to identify ways to protect metabolic health.

Neural circuits

Calcium imaging

Feeding behavior

RECENT DISCOVERIES

New insights into metabolic disorder

NEURON, 2026

A vulnerable signaling partnership in clozapine-induced weight gain

Developmental reprogramming in melanocortin neurons changes how mice respond to a high-fat diet, connecting cell identity established early in life with adult energy balance.

Our newest work connects molecular mechanisms to whole-body physiology and clinically important forms of obesity.

NATURE COMMUNICATIONS, 2026

When early neural identity shapes adult metabolic risk

Our work identifies functional coupling between MC4R and the potassium channel Kir7.1 as an important convergence point through which clozapine promotes overeating and weight gain.
