The formation of precise neural connections during development is critical for proper brain function We use a combination of single-cell transcriptomic analysis, animal models, virus-mediated axon tracing and in vivo electrophysiology to identify the molecules and mechanisms mediating correct neural circuit...
We study how cells build the human body. We use human pluripotent stem cells to build organoids that recapitulate essential features of developmental processes. With these simplified in vitro models, we dive deep into mechanisms that integrate gene regulation,...
Disrupted social behavior is a core feature of compromised mental health, including anxiety and depression, and is a long-standing early diagnostic marker of disorders that emerge in later-life. Yet, we have little understanding of the ontogeny of social behavior...
Epithelial-to-mesenchymal transition (EMT) is a cellular lifestyle change that produces highly invasive cells that can migrate long distances in the body. These processes are critical for normal embryonic development but are often reactivated in disease states such as cancer...
Neural circuit mechanisms underlying the development of social behaviors Adolescence is a period of physical and psychological development during which a person develops from a child into an adult. Following the onset of puberty, increased hormonal levels stimulate the...
Single cell gene molecular profiling has demonstrated that cell classification requires more than a simple collection of markers. Current approaches do not account for the dynamic nature of cell states and inherent variation in cell types. This is especially...
The evolution of multicellularity occurred hand in hand with the diversification of cell types with disparate morphologies and functions. This segregation of function across different cell types enabled astounding animal complexity; but at the same time, extreme specializations of...
Understanding the brain using evolution, viruses, and barcode sequencing. Our research aims to understand the structure and function of the brain. To do so, we take a comparative approach and develop molecular, viral, and sequencing technologies to measure neuronal...
Redox regulation plays a central role in signal transduction processes operating in the brain. Aberrant redox signaling is a hallmark of several neurodegenerative diseases such as Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, Amyotrophic Lateral Sclerosis and various Ataxias. It...
Our research is focused on understanding how neuronal connectivity is established during development. Our work investigates the function of extrinsic guidance cues and their receptors on axonal guidance, dendritic morphology, and synapse formation and function. For several years we...
