Title: Human Genome Annotation

A central problem for 21st century science will be the analysis and
understanding of the human genome. My talk will be concerned with
topics within this area, in particular annotating pseudogenes (protein
fossils) in the genome. I will discuss a comprehensive pseudogene
identification pipeline and storage database we have built. This has
enabled use to identify >10K pseudogenes in the human and mouse
genomes and analyze their distribution with respect to age, protein
family, and chromosomal location. One interesting finding is the large
number of ribosomal pseudogenes in the human genome, with 80
functional ribosomal proteins giving rise to ~2,000 ribosomal protein

I will try to inter-relate our studies on pseudogenes with those on
tiling arrays, which enable one to comprehensively probe the activity
of intergenic regions. At the end I will bring these together, trying
to assess the transcriptional activity of pseudogenes.

Throughout I will try to introduce some of the computational
algorithms and approaches that are required for genome annotation and
tiling arrays -- i.e. the construction of annotation pipelines,
developing algorithms for optimal tiling, and refining approaches for
scoring microarrays.
