Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Did you know there are 2 types of avocado varieties? A-types switch from female to male, B-types male to female, within a single day. This reciprocal sex alternation promotes cross-pollination and has a simple genetic basis. Read more in this recent preprint from the final chapter of my PhD thesis 🥑

Excited to share the preprint of my last PhD chapter, "Warm waters undermine cryptic female choice." We find that warm temperatures relevant to climate change reduce female influence on sperm velocity and expected paternity of preferred, dominant males in the ocellated wrasse.

Warm waters undermine cryptic female choice

Reproduction is often more thermally sensitive than survival. Thus, understanding the thermal sensitivity of reproductive interactions is crucial given global warming. However, it is unknown how tempe...

I am an evolutionary ecologist that uses marine invertebrates—especially sea urchins and their echinoderm relatives—to study how microbial symbioses are essential to reproduction and development.

I'm finally getting around to doing my intro post. I'm a postdoc interested in the molecular interactions between the ejaculate and the female postmating, and their potential to contribute to reproductive isolation and speciation. 🧪👩‍🔬#HiSciSky #AcademicSky
