Postdoctoral Positions in Biomedical Image Analysis, Computer Vision, Image Processing, Scientific Visualization

DoD-Supported Postdoctoral Fellow in Realtime Imaging (immediately available) NASA-Supported Postdoctoral Fellow in Satellite Imaging and Visualization (filled)

Multi-modal, multi-spectral, multi-view imaging is creating a new class of challenging research problems in image registration, rectification, localization, object extraction, 3D structure estimation, object classification, object tracking, and multi-dimensional visualization. These common computer vision, image analysis and visualization problems are shared across multiple disciplines. In our case three related projects use similar computational and visualization approaches. One project is to locate, classify and track cells in live-cell microscopy for biomedical applications (see below). Another project is to improve hurricane forecasting by assimilating satellite observations and visualizing numerical model results through realtime automatic deformable 2D/3D cloud tracking and flow visualization. The third project is to track vehicles and people in large format wide-area video and use this information for event and activity analysis and video summarization. Other common goals include realtime parallel processing (multicore GPU or Cell clusters) and 3D visualization.

Desirable/required skills include a doctoral degree in EECS or related field with a solid background in image analysis, computer vision, pattern recognition and computer graphics with excellent programming experience (C++ and Matlab) including numerical PDE solvers, OpenGL, Qt GUI design, use of libraries like VTK, ITK, OpenCV, Boost, etc. Knowledge of level-sets, kernel classifiers and pyramid data handling techniques would be highly advantageous.

Postdoctoral positions are available to join an ongoing research project in the quantification of deformable motion in biology, with emphasis on cell motility, tissue growth and tumor development.

Our research has led to extremely promising algorithms for cell tracking (hundreds of motile cells over hundreds of time-lapse image sequences) with application to high throughput sequencing studies for genome analysis and drug discovery. Quantitative live cell imaging within a biological context offers promising new opportunities to understand cellular and sub-cellular processes that have never been observed before, ranging from the autophagic clustering behavior of cancer cells to microtubule regulation of actin and cell cycle biology. A series of recent papers listed below describe the computational algorithms for tracking deformable motion of biological objects, in particular motile animal cells and embryos. The position at Missouri is primarily computational (with bio-imaging opportunities possible based on candidate interest). The successful candidate for this position will have a strong background in image analysis, computer vision, or computer graphics with an emphasis in active contour and level set based image segmentation, data fusion and object tracking.

About the University of Missouri-Columbia

The University of Missouri is highly ranked as postdoctoral fellowship training center and is a leading research university. It one of only six American universities with the greatest breadth of academic units on a single campus that includes engineering, science, mathematics, medicine, business, law, journalism, agriculture, natural resources, environmental sciences, veterinary medicine, health sciences, nursing, education, humanities, and liberal arts. This enables novel collaborations in multidisciplinary research to be pursued, for example, engineering and medicine. UMC's current endowment campaign goal is to raise $1 billion by the end of 2008 - the 26th public university in the nation to have such a campaign.

The University of Missouri-Columbia (UMC or MU) was established in 1839 as the first public university west of the Mississippi river in the Louisiana Purchase - territory that was acquired from Napolean in 1803 by US President Thomas Jefferson. UMC is a nonprofit land grant academic and research institution that is recognized as one of the leading tier-one research and Carnegie-Doctoral-Research-Extensive institutions in the country. UMC is the flagship public university in the state of Missouri with over 21,500 undergraduate and 7,000 graduate and professional students. UMC has been a member of the Association of American Universities since 1908; the AAU was founded in 1900 and is currently composed of 62 leading research universities in the US and Canada.
