Recently, my has published a resource aimed at collection, re-analysis and probe-level visualization of oncogenomic array data. This "arrayMap" resource can be accessed at www.arraymap.org.
In December 2000 I launched the Progenetix project, a reference database of (molecular-) cytogenetic aberration data in human malignancies. The data is represented in formats suitable to data mining approaches. Various data analysis and visualization tools were developed for the Progenetix project and are accessible through the website. Currently, the Progenetix database contains results from more than 29000 genomic profiling experiments using chromosomal and array based CGH techniques. Additionally, the website is a comprehensive publication tracker for oncogenomic data from array CGH, chromosomal CGH and metaphase analysis studies.
Aside from general CNA data collection and software development, my group is involved in cancer type specific analysis projects. These studies are usually collaborative projects, with a current focus on childhood brain tumors and and malignant lymphomas.
