Biology is an increasingly computational discipline due to rapid advances in experimental techniques, especially DNA sequencing, that are generating data at unprecedented rates. The computational techniques needed range from the complex (.e.g algorithms, distributed computing) to the simple (e.g. scripting, parsing), and there are hundreds of thousands of Biologists now involved in computing. We propose that OCaml can serve virtually the full spectrum of computational tasks needed by Biologists, improving both programmer productivity and computational efficiency. To support this end, we have developed Biocaml.
