Post-Doc associated with: John Guckenheimer, Francisco J Valero-Cuevas Keywords: Computational Neuroscience (13), Hippocampus (11), Learning and Memory (13), Mathematical Modeling (14), Motor Systems (13), Sensorimotor Systems (11), Systems Neuroscience (25) Mathematical and computational tools for development and analysis of dynamical models for integrated neural / motor systems. We represent physiological systems using Dynamical Systems Theory. We use Hodgkin-Huxley-type membrane equations for neurons, and standard rigid body dynamics for the mechanics of locomotion. Applications at Cornell include feedback control of finger movement (with Francisco Valero-Cuevas), and insect locomotion (with John Guckenheimer). |

Post-Doc associated with: Andrew H. Bass Keywords: Biomechanics (2), Evolution (5), Fish (12), Functional Morphology (1), Motor control (1), Motor Systems (13), Neuroethology (24), Neuromodulation (12), Sensorimotor Systems (11), Zoology (2) I am interested in the mechanisms, ethology, and evolution of sound production in fishes. Among other things, I am investigating how monoamine neurotransmitters modulate the vocal communication in toadfishes. |
Post-Doc associated with: Joseph R. Fetcho Keywords: Biomechanics (2), Evolution (5), Fish (12), Lateral line system (2), Neuroethology (24), Sensorimotor Systems (11) I am broadly interested in the sensory biology, evolution, and behavior of fishes. In the Fetcho lab I am trying to understand how sensory inputs are translated into motor outputs at the cellular level using optical, genetic, and electrophysiological techniques in zebrafish. |
Post-Doc associated with: Andrew H. Bass Keywords: Auditory Neuroscience (5), Fish (12), Lateral line system (2), Neuroethology (24), Neurophysiology (5), Sensorimotor Systems (11), Vocal Motor Systems (3) My main research interest are the sensory systems of fish, especially the octavolateral sensory systems. |
Post-Doc associated with: Joseph R. Fetcho Keywords: Cell and Molecular Neuroscience (23), Development (21), Fish (12), Motor Systems (13), Neuromodulation (12), Systems Neuroscience (25) I investigate the modulation of developing spinal circuits in zebrafish, using optical, genetic and electrophysiological approaches.

Post-Doc associated with: Carl D. Hopkins Keywords: Computational Neuroscience (13), Electroreception (3), Fish (12), Mathematical Modeling (14), Neuroethology (24), Systems Neuroscience (25) My research interests primarily deal with general principles of neural coding and processing in spiking neurons of sensory systems, in particular issues related to the potential for "temporal", as opposed to "rate", coding and processing schemes. Secondarily, I am interested in the statistical structure of neural spike trains, and deterministic explanations for this structure. I am currently studying the neural pathway that processes electrical communication signals in weakly electric fish from Africa, which must detect differences in the waveforms of very short (< 1 ms) electrical pulses. I hope that the general strategies used by this relatively simple and specialized neural system will prove useful in suggesting and guiding research on other more complex sensory systems, such as the mammalian auditory system. |
Post-Doc Keywords: Cell and Molecular Neuroscience (23), Motor Systems (13), Neuroethology (24), Neurotransmitter receptors and transporters (9) I joined Dr. Ron Hoy's laboratory in 2005. We are currently investigating changes at the neuromuscular junction (NMJ) in various mutants of Drosophila melanogaster. This information will be applied to the new educational program, The Fly CD, which is a follow-up to the Crawdad CD. |
Post-Doc Keywords: Olfaction (11) Chemical communication and individual recognition; the neurobiological mechanisms of recognition and memory. |
Post-Doc associated with: Dave M. Lin Keywords: Cell and Molecular Neuroscience (23), Development (21), Mouse (11), Olfaction (11) My work involves trying to identify molecules and processes in the olfactory epitheleum that affect (i) Axon Guidance (ii) Gene Expression of olfactory receptors Our lab uses the mouse as a model system to understand the biology behind these events. Until now, my research has been limited to the screening of several putative axon guidance molecules (involved in other axon guidance events in other systems), and assaying for odorant receptor expression profiles. The primary means to do this is by RNA in-situ hybridization on serial sections of the nose of mice at various stages. More broadly, I envisage to exploit rapidly developing technologies like DNA micro-array technology, and perhaps some proteomic assays, to understand the role of individual molecules in the context of the several other molecules likely to have a role in these events. |
