I'm no longer a student at UMass, but they let former Doctoral students keep web pages.

My thesis was: Table Visualizations, a Formal Model and its applications (now available). This researched machine learning and visualization (Datamining). 

Unfortunately, AnVil Informatics or AnVil, where I did Analysis and Visualization is no more.
AnVil was founded based on my research here at UMass where I invented RadViz and other visualizations.

Yes it's sad, but the good news is:

I was (3 yrs) at Oracle doing data mining (and some visualization).

but now I am at InforSense still doing data mining with more visualizaton

MIVAC is (not) Back! To learn more click the multi-colored link!

This is a Java applet that demonstrates most High Dimensional Visualizations.
The applet is more of a "proof" of concept; written almost 5 years ago.
The technology has been advanced greatly and incorporated into AnVil's data mining platform,
which is potentially available to interested parties.

For more information, please see the papers below. For more personal details see here

Data mining and Visualization applied to Bio/Chem Informatics is my current research area.

The data mining visualizations below were developed from my research at the IVPR and
along with some unique machine learning algorithms are potentially available to interested parties.

Here is the paper that introduces RadViz - A visualization that can effectively handle thousands of dimensions - DNA Visual And Analytic Data Mining presented at Visualization '97.

This paper extends the RadViz concept and shows how to produce any high dimensional visualization from a graphic primitive called a Dimensional Anchor Dimensional Anchors: A Graphic Primitive for Multidimensional Multivariate Information Visualizations

Two additional papers survey high dimensional visualizations and benchmark high dimensional visualizations
