The Phylogenetic Likelihood Kernel (PLK) is an important and compute-intensive Bioinformatics function that is used to infer phylogenetic (evolutionary) trees from molecular sequence data. This kernel typically consumes 85-95% of the total run time in algorithms for phylogeny reconstruction which represent a common task in biological data analysis. I will briefly outline the underlying mathematical ideas at an abstract level. Then, I will describe a dedicated HW architecture to compute the PLK and address parallelization strategies for various computer architectures such as current multi-core systems and the IBM BlueGene/L. I will conclude with a brief overview of future work and potential topics for joint work.
