me, eating popsicle. by Amelia, age 5

I am a Research Assistant working in Theodore J. Perkins' lab at the Ottawa Hospital Research Institute.


I do variety of things here, including:

  • Development of custom data analysis and data visualization software, such as PhyloviewBluster, ARD and MLTrends.
  • Assorted data aggregation and analysis of Microarray, SAGE, Proteomics, Solexa and other data in support of work by our group and other OHRI and the Stem Cell Network researchers.
  • Maintenance of the StemBase system: extending and maintaining the software and curating data added to the system.
  • Hiring and supervision of high school, college and unversity students.
  • The care and feeding of our compute cluster, various departmental servers, the associated software menagerie and this web server.
  • Setting up and supporting Mascot, a BioWorks Sequest cluster, the Trans Proteomics Pipeline analysis system and the Solexa sequence anaysis pipeline.
  • In supporting and collaborating with students and researchers in the OHRI and the Stem Cell Network, our group provides training in Bioinformatics, microarrays and data analysis:
