The Barna Lab seeks to address how the living blueprints of developing organisms are built.
The Beachy lab studies the function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation) and in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.
We seek to understand the control of gene expression.
A major direction in the lab is to understand how such long-range interactions occur, how they achieve target specificity, and how they may be reprogrammed by alterations to the genome sequence.
Small-molecule modulators of the Hedgehog pathway
Our aim is to identify and characterize systems that influence the interplay among genetic variation, phenotypic diversity, and environmental fluctuations at the molecular level, integrating our findings to gain insight into complex cellular systems.
Seung Kim Lab
Our goal is to identify and understand the pathways that govern organogenesis of the pancreas, a vital organ with endocrine and exocrine functions.
The Molecular Basis of Vertebrate Evolution.
Our laboratory is interested in the growth, development and integrity of animal tissues. We study multiple different organs, trying to identify common principles, and we extend these investigations to cancer and injury repair.
Our research focuses on the development and function of glial cells in the vertebrate nervous system. Using genetic screens and cellular approaches in zebrafish, we aim to discover new genes with essential functions in glial cells, define new animal models of important disorders in humans, and provide new avenues toward therapies for injury and disease of the nervous system.
Research in the Villeneuve lab is aimed at understanding the molecular and cellular mechanisms underlying the faithful inheritance and function of eukaryotic chromosomes. Our primary focus is on elucidating the events required for the orderly segregation of homologous chromosomes during meiosis, the crucial process by which diploid germ cells generate haploid gametes.
We are a discovery-driven research group working at the interface between developmental biology, bioengineering, and statistical physics. We combine quantitative organism-wide fluorescence imaging ("deep imaging"), functional genomics ("deep sequencing"), and statistical modeling to understand the fundamental rules that control collective cell behaviors to optimize tissue organization, regeneration, adaptation, and evolution. We also seek opportunities for applying these rules to improve engineering systems.
