Development and application of microdevices for instrumenting and controlling single living cells

Research Description
John Wikswo and his group are at present working in three areas: the study of the linear and non-linear electrical properties of cardiac tissue during stimulation, propagation, and recovery for threshold- and defibrillation-strength shocks; the magnetic measurement of cellular action currents in cardiac and intestinal tissue, as can be observed using SQUID magnetometry; and the development and application of micro- and nano-scale devices for instrumenting and controlling the single biological cell and small populations of cells. His long-term program to understand the effects of defibrillation-strength shocks on cardiac tissue now includes studies of charge and electroporation and molecular diffusion. The magnetic studies of action currents range from determining the information content of the magnetocardiogram in isolated rabbit hearts to the non-invasive diagnosis of intestinal ischemia in humans. The project to instrument and control single cells is addressing issues as varied as the use of cells to identify and discriminate chemical and biological warfare agents by metabolic phenotype; the development and application of BioMEMS (BioMicroElectroMechanical Systems) devices to understand the molecular signaling associated with chemotaxis, cellular motility, angiogenesis, and metastasis; and the nature of the signaling and metabolic activity associated with the immune response.

Postdoctoral Position Details
EMD Millipore Research Associate in Automated Systems Biology

With the support of EMD Millipore Bioscience, the Vanderbilt Institute for Integrative Biosystems Research and Education (VIIBRE) is seeking candidates for a research associate in either of the Departments of Physics & Astronomy, Biomedical Engineering, or Molecular Physiology & Biophysics. The successful candidate will be expected to conduct both experimental and computational research as a part of a long-term project in the automated inference of mathematical models of metabolic and signaling dynamics of small populations of cells. Techniques being used include microfabricated bioreactors with optical, electrochemical, and mass spectrometric sensing, closed-loop control, microfluidics, numerical modeling, and bioinformatics. A doctoral degree in a related field is required. Apply at Review of applications will begin on 1 July, 2011 and will continue until the position is filled.
VIIBRE is a transinstitutional initiative created in 2001 to foster and enhance interdisciplinary research in the biophysical sciences, bioengineering, and medicine at Vanderbilt University, integrated with a strong focus on undergraduate, graduate, and postdoctoral education. VIIBREa??s primary focus is the use of microfluidics and advanced analytical systems to instrument and control single cells and small populations of cells. Founded in 1873, Vanderbilt is a private, coeducational university with approximately 6,000 undergraduates and 5,000 graduate and professional students. Vanderbilt University is an equal-opportunity, affirmative-action employer. Women and minority candidates are particularly encouraged to apply.
