Many interesting speakers in this workshop in Dundee but most of them fall in the mathematics part of biomathematics. Among the few who do not is the biologist Vito Quaranta (Vanderbilt University). Although I have been told many times that things are changing for the better in that respect, the scarcity of life scientists and medical doctors in these type of conferences tells me that there is still a lot of work to do to convince them that computational and mathematical biology is not only relevant but necessary.
The talk from Vito Quaranta was not so much about science as about doing science at the interface between theory and experiments. He is lucky to count with the resources of the Vanderbilt Integrative Cancer Biology Center. Otherwise the problem of validating the mathematical and computational models with theoreticians come with would be next to impossible. This theoretical models make a number of assumptions about the properties of tumour cells, tissues and micro environments and predict outcomes that in many cases have to be contrasted with in vivo and in vitro experimental results. This experimental work is really challenging given the level of fragmentation of knowledge and expertise in biology and medicine. Different labs with different experimental techniques, machinery, cell lines and the necessary permissions to perform animal experiments and access human clinical data are required to validate one single theoretical model. That means that unless centres like the one in Vanderbilt become much more common most theoretical models will remain experimentally untested unless they proof to come out as the result of the consensus of the theoretical biology community.
