When University Of California (Davis) Professor of Evolutionary Biology, Professor Jonathan Eisen, was scheduled to speak at a meeting on Metagenomics in the Era of Big Data, he found himself in a bit of a pickle – or more to the point, a YAMMM. This stands for: yet another mostly male meeting. The male speakers outnumbered women 21:6. He considered his options. In the past, he has submitted a conference abstract in protest, A quantitative analysis of gender bias in quantitative biology meetings. He has also written to organisers and publicly called them out on their gender exclusion. This time, he considered not going, but then came up with a clever approach to tackling YAMMM.
