I am entering my second year of graduate school working under Prof. Claudio Silva in the Visualization and Geometric Computing Group at the SCI Institute. My undergraduate work was done at Northeastern University in Boston, MA earning me B.S. degrees in both Electrical Engineering and Computer Science.

After graduating from Northeastern I moved to Sydney, Australia where I played on the New South Wales state LaCrosse Team and a team representing Australia in the South Pacific LaCrosse Tournament. Upon returning to the U.S. I worked closely with the SCI Institute and Massachusetts General Hospital in their Dept. of Radiation Oncology developing new visualization techniques to aid them in the diagnosis and treatment of various cancers.

Currently, I am working with Gilbert A. Preston to develop an integrated, multi-modal visualization system for his research in studies based on memory, attention, and the genetic substrates of such effects. These efforts are also being used to advance the visualization techniques used for Costal Margin Observation and Prediction (CMOP) as well as visualization of cosmological data, such as that used by Dr. Katrin Heitmann at Los Alamos National Laboratory.

VisTrails 1.0 Packages

NumSciPy.tar.gz	Package wrapping some of the functionality of Python's Numpy and SciPy packages. At this time it is an incomplete wrapping, but more functionality is being continually added. A wrapping of the NDArray class provides array access and manipulation modules while conversion modules provide mechanisms to convert between arrays and matrices. Additional functionality includes partial wrappings of the imaging, signal processing, IO capabilities of Numpy and Scipy To install this package, first install the Python SciPy package. A binary installation of this package is recommended as it can be tricky to build from source. After the Python package is installed, extract the above tarball and run the setup script. >>> python setup.py install This will install the package to the default userpackages directory. If a different location is necessary, add the flag: --install-lib= To enable Stockwell Transforms, add the flag: --with-stockwell Note: Stockwell Processing requires the installation of the fftw3 library.	Example VisTrail
Matlab.tar.gz	Package wrapping Matlab for VisTrails. This package is capable of executing any Matlab command and passing data back and forth between Python and the Matlab execution engine. The python package mlabwrap and a working Matlab installation are required for the proper functioning of this package. To install this package, install mlabwrap using the direction on their website and place the wrapper files into $HOME/.vistrails/userpackages After starting up VisTrails, enable the package in the Preferences dialog. Please note: This package relies on the scipy and numpy Python packages as well as the SciPy VisTrails Package.	Example VisTrail
ITK.tar.gz	Package wrapping the Insight Toolkit for use in VisTrails. It is currently capable of loading a single-serie DICOM volume, slice it, and perform some segmentations on it using wrapped ITK functionality. To install this package, install The Insight Toolkit using the directions on their website, making sure to enable WrapITK and disabling CSWIG_PYTHON during the build process. Then, place the wrapper files into $HOME/.vistrails/userpackages After starting up VisTrails, enable the package in the Preferences dialog.	Example VisTrail
