Faculty Keywords: Cell and Molecular Neuroscience (23), Genetics (9), Imaging (8), Ion channel (6), Mouse (11), Neuromodulation (12), Systems Neuroscience (25) My lab works on the molecular processes underlying excitation-contraction coupling in heart and smooth muscle cells. Membrane and intracellular ion channels and associated regulatory programs are functionally examined using genetic, molecular, and biophysical approaches. The laboratory concentrates on gene inactivation and overexpression in transgenic mice and the molecular evaluation of the function of the targeted genes. The laboratory is also involved in the development of new imaging technologies using purpose –designed sensor molecules that provide a unique insight into complex, physiological and pathological interactions between specialized cell types in vivo. These studies are pursued by a diverse and extraordinarily talented group of scientists and students in the laboratory. Also visit my Research/Photo Gallery entry |
Faculty associated with: Ashok Gopinath, Eric Williams Keywords: Axon guidance (3), Cell and Molecular Neuroscience (23), Development (21), Genetics (9), Mouse (11), Neurogenesis (7), Olfaction (11), Sensorimotor Systems (11) My lab is interested in the development of the mouse olfactory system. How are millions of olfactory sensory neurons in the nose able to find their appropriate targets in the olfactory bulb? We use molecular and genetic tools to understand this process of axon guidance and target recognition. The olfactory system is also one of the few systems that undergo regeneration in the adult animal. Are the same mechanisms and molecules used during regeneration as during development? By understanding this process in the embryo may provide insight into how regeneration is maintained during adulthood. |
Faculty Keywords: Behavioral Ecology (2), Birds (4), Development (21), Evolution (5), Fish (12), Mathematical Modeling (14), Neuroethology (24), Vision (11) I work in the area of visual ecology dealing with the question, "why do animals have the color vision systems they do?" The obvious evolutionary requirement is that the visual system be adapted for the visual tasks it must perform in the environment in which the animal lives. Research questions are: 1. What are the physiological characteristics of the visual system? I concentrate on the spectral properties of the photoreceptor cells as these represent the input to the visual system; 2. What is the nature of the photic environment? Measurements of the light available for vision and the optical characteristics of visual targets are measured; and 3. What are the visual tasks that the visual systems seems to be adapted for? This usually requires a knowledge of visual behaviours. Thus, my lab works in all three of these research areas bot here at Cornell, and out in the field. |
Faculty Keywords: Birds (4), Development (21), Fish (12), Imaging (8), Mathematical Modeling (14), Sensorimotor Systems (11), Systems Neuroscience (25), Vision (11) I conduct research into the physiological optics of human and animal eyes. Past projects have concerned a longitudinal study of anisometropia and anisometropic amblyopia in humans, emmetropization of the chick eye to spectacles, the chick eye's response to light regimes, and aberrations of human eyes. Earlier I worked on the role of the otolithic organs and semicircular canals in the orientation of fish. I have also conducted on the allometry (scaling with body size) of eyes and inner ears. |
Faculty associated with: Sunayana Banerjee Keywords: Bird Song (2), Development (21), Finch (4), Immediate early genes (5), Neuroendocrinology (7), Neuroethology (24), Social behavior (12), Stress (8) I am interested in neuroendocrine mechanisms of social behavior and social relationships in birds. The research seeks to answer questions such as, how are sex differences in brain and behavior produced in development? What are the mechanisms responsible for mate choice? For the formation and maintenance of long-term pair relationships in socially monogamous birds? |
