Following @RobLanfear 's plea.
I've worked (early retired) on #phylogenetics at evolution's coalface (from marine protozoans to extratropical trees), at the junction of #paleontology and #neontology, the crossroads of #bioinformatics and #application

Love to quick-help with graph interpretations—e.g. https://phylonetworks.blogspot.com/2019/12/trees-informing-networks-explaining.html and https://phylonetworks.blogspot.com/2019/04/next-generation-neighbor-nets.html
