Dr. Rafael Yuste, Departments of Biological Sciences and of Neuroscience. The Yuste laboratory studies the structure and function of cortical circuits using advanced optical and biophysical approaches. By imaging and manipulating the activity of neurons in living mouse brains, the group attempts to decipher the function of the mammalian neocortex and understand how dendritic spines contribute to the circuit function. This work could lead to better understanding of the pathophysiology of epilepsy and schizophrenia. In addition, the Yuste lab is pioneering the use of the Cnidarian Hydra vulgaris as a model system for the comprehensive measuring of all neural activity in an animal during its behaviour. The Yuste group also helped inspire the White House's BRAIN initiative, a large-scale scientic project to develop new methods for Neuroscience. There are currently 22 students and staff working in the Yuste lab.

Franck Polleux, Department of Neuroscience. Throughout his career, Dr Polleux has focused on the identification of the molecular mechanisms underlying neuronal development in the mammalian brain. More recently, his lab also started studying the genetic basis of human brain evolution as well as the signaling pathways underlying synaptic loss during early stages of Alzheimer’s Disease progression.

Dr. Stavros Lomvardas, Department of Pathology and Cell Biology. Our research program aims to understand the molecular mechanisms of olfactory receptor gene choice. Olfactory receptor (OR) genes compose the largest mammalian gene family consisted of more than 1000 members. These genes are expressed in a stochastic and mutually exclusive fashion in such a way that only one OR allele is expressed in each olfactory sensory neuron. Our data suggest that this unusual expression pattern is orchestrated by a combination of positive and negative regulatory mechanism. According to our findings, OR genes undergo chromatin mediated silencing at a developmental stage that precedes olfactory receptor activation. One of the 3000 alleles is chosen for activation, by the enzymatic removal of the silencing chromatin marks. We currently combine genetic and biochemical approaches that together with cutting edge microscopy should reveal critical mechanistic details of this process.

Dr. Virginia Cornish, Department of Chemistry. Synthetic Biology aims to engineer artificial pathways in cells both to test fundamental notions of how complex biological networks function and to develop new technologies for the treatment of disease.  Moving beyond advances in the last century for the synthetic manipulation of biomolecules in vitro, the Cornish laboratory is creating conceptually new approaches for the modification of biomolecules in a living cell.  As opposed to designing molecules that can be added to the cell with minimal perturbation of its natural functions, their approach is to design molecules capable of co-opting the cell's own highly evolved and integrated synthetic machinery (evolution and translation) for production of the modified biomolecules in vivo.  Finally, they are using these new synthetic methods to develop tools for live cell imaging.  There are currently 12 students and staff working in the Cornish laboratory.

Dr. Brent Stockwell, Howard Hughes Medical Institute, Department of Biological Sciences and Department of Chemistry. The Stockwell laboratory is exploring two biological questions using chemical tools. First, what is the full range of cell death processes, and how are these processes regulated. In this context, we discovered an alternative form of cell death that we termed ferroptosis, for its critical reliance on cellular iron. We are examining the mechanism of this form of cell death, as well its relevance to numerous diseases.  Second, we are testing the notion that 85% of proteins are resistant to small molecule modulation by using a computational design strategy to create small molecule inhibitors of these historically undruggable proteins. This would have profound ramifications for drug discovery and medicine. There are currently ~20 students and staff working in the Stockwell laboratory.

A main research thrust is to establish new photophysical mechanisms that may be utilized to revolutionize solar energy conversion or light emission. As examples, recent discoveries in our lab showed how an electron and a hole is bound by the Coulomb potential across an organic semiconductor interface, how an exciton can split into two via the singlet fission process, and how hybrid semiconductors can yield the highest possible quantum efficiency in light emission.
