Research

Our goal is to advance predictive biology for tissues. We seek to uncover fundamental principles by which cells interact to generate stable, adaptive, and resilient tissues in the face of fluctuating environments. We view tissues not as collections of cell types, but as dynamic circuits composed of interacting cells that together govern homeostasis, remodeling, and failure. Our central question is: what are the minimal cell-cell circuit motifs that sustain tissue function? How are these circuits rewired across development, physiological fluctuations, aging, and disease? Drawing inspiration from systems theory, we aim to define the “grammar” of cellular interactions that underlie robust tissue behavior.

We study these principles across the ovarian and cardiovascular systems to identify conserved and context-specific rules of tissue organization. By integrating cutting-edge spatially resolved and genomics technologies, machine learning, and mechanistic models, we investigate how cells encode dynamic organismal cues such as hormonal cycling, inflammation, and stress, and how cell-intrinsic and cell-extrinsic interactions self-organize into reproducible spatial patterns during tissue remodeling. Ultimately, our goal is to move beyond descriptive atlases toward causal, predictive models of tissue organization, enabling the discovery of mechanisms that drive resilience versus failure to inform new therapeutic strategies for age-related and hormone-dependent diseases.

Tissue resilience in cardiovascular disease

Our research focuses on understanding tissue resilience in cardiovascular disease: the ability of human vascular tissues to maintain function and recover after stress or injury. We combine multi-omics, histology, and deep learning to identify the molecular and cellular programs that preserve homeostasis or promote repair in the face of chronic stress. A major focus is on how the extracellular matrix, immune cells, and vascular smooth muscle cells interact to either stabilize or destabilize the vessel wall. By uncovering the early molecular events that distinguish adaptive remodeling from pathological degeneration, we aim to identify biomarkers of disease progression and therapeutic targets that restore vascular resilience.

Ovarian aging

The ovary is one of the first organs to age. Both its reproductive and endocrine functions rely on dynamic changes in cell type composition, cellular programs, and their interactions across the estrus/menstrual cycle. Remarkably, these cyclical processes cease with age, but the underlying cellular and molecular changes that drive this transition remain poorly understood. We combine cutting-edge spatial profiling, in vivo lineage tracing, and machine learning to uncover the drivers of ovarian aging, with a particular focus on immune and vascular dysfunction. By studying the ovary as a model system, our goal is to uncover fundamental principles of tissue organization, translate these insights to human biology, and identify novel therapeutic targets.
