  • Biography

    Jonathan Sweedler received his Ph.D. from the University of Arizona in 1988. He is a Lycan Professor in the Department of Chemistry, the Bioengineering Program, the Department of Molecular and Integrative Physiology, the Neuroscience Program, is the Director of the University of Illinois Biotechnology Center, and is a part-time faculty member in the Beckman Institute's NeuroTech groups. His fields of professional interest are the neurochemistry of neuropeptides and indoleamines, and the development of new technology for assaying the cellular microenvironment using capillary separations, single cell mass spectrometry, and nanoliter volume NMR spectroscopy.

  • Research

    Jonathan Sweedler's research emphasizes the development and implementation of new analytical instrumentation and methodology, and the elucidation of the functional roles of multiple neurotransmitters and neuromodulatory compounds in individual neurons and well defined neuronal networks in the common neuronal model system, Aplysia californica. Much of his research group's work involves scaling a variety of methods to the nanoliter volume regime to allow the identification and quantitation of neuroactive compounds from cellular microenvironments.

    In terms of analytical methodology (primarily BSG research), Sweedler is developing new microseparation methods based on capillary electrophoresis and chromatography, and has demonstrated unique detection modes such as wavelength resolved fluorescence, radiochemical, and NMR. His group, in collaboration with other members of the Biological Sensors Group, improved the sensitivity so that high quality NMR spectra can be reliably obtained on picomole samples. One of the most significant methods under development in his laboratory involves profiling the peptides in individual neurons using matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometry.

    A large subset of his group's research (primarily within the NeuroTech Group) is designed to understand the molecular (chemical) nature of learning and behavior. Using the techniques described above, they are studying the neurotransmitters and neuromodulatory compounds used in simple and well-defined invertebrate neuronal networks, such as the bag cell neurons that control aspects of reproduction and several groups of neurons involved with feeding in Aplysia californica. They have discovered many cases of previously unknown processing of known neuropeptides, as well as previously unknown peptides. Increasing our understanding of the functional roles of cotransmission in relatively simple neuronal systems directly contributes to the Biological Intelligence research theme at the Beckman Institute.

    Sweedler's major sources of research funding are the NSF, NIH, and private foundations.
