RNA metabolism dysfunction and RNA-targeting therapy in neurodegeneration The nervous system has extremely complex RNA processing regulation. Dysfunction of RNA metabolism has emerged to play crucial roles in multiple neurological diseases. Mutations and pathologies of several RNA-binding proteins are...
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...
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...
Understanding how the information in the genome is utilized is one of the central questions in modern biology. It has become clear that a critical level of gene regulation occurs through the chemical modification of both the DNA itself...
My research is focused on pushing the limits of single-molecule detection methods to study complex biological systems. His group develops state-of-the-art biophysical techniques (e.g., multicolor fluorescence, super-resolution imaging, combined force and fluorescence spectroscopy, vesicular encapsulation, single-molecule pull-down) and applies...
The vertebrate central nervous system (CNS) is an amazingly complex structure composed of distinct subtypes of neurons and glia. Our lab aims to identify the molecular mechanisms that control the generation of the major cell types of the vertebrate...
Eukaryotic cells package their genomes in the form of chromatin, which is comprised of histone proteins and DNA. Modification of chromatin by chemical marks such as methylation and acetylation affects how cellular machineries interpret the genome. The Taverna laboratory...
Protein function is dynamically regulated in the cell by reversible posttranslational modifications. We are interested in the mechanism by which chromatin modifications regulate transcription, nucleosome dynamics and the response to DNA damage. A particular focus is on the non-degradative...
What are cellular and molecular mechanisms that control tissue regeneration in vivo? Stem cells ensure tissue renewal in most adult tissues, and their activities are under the precise control of signals from specific local microenvironments, or niches. The ability...
