Dr Hannah C. Butler

My post-doctoral research position involves looking at the pollination system of various flowering plants. Previously I have worked on mostly Amaryllidaceae and enjoy continuing to do so. But currently I am trying to broaden this by working on other families that I love, including Orchidaceae and Apocynaceae. My work consists of mostly natural history studies, or ‘what pollinates what’ and how this fits into a bigger picture of evolution. I am also enjoying being able to lecture undergraduate modules.
