PhD candidate studying mutation rates and demographic histories in Koalas (and all marsupials). Honours studying cave cockroaches! Member of AWGG and MEEP @USYD
Sydney, New South Wales
Joined October 2019
🚨!Out now in Systematic Biology!🚨 Read how we hurt molecular clocks 🪦with the ridiculous substitution rate acceleration found in the mitochondrial genomes of these cool looking cave cockroaches. They indeed leave the rest of cockroaches in the dust! https://t.co/qCOGKE2FKf

ゴキブリが嫌いな人に理由を聞くと 「動きが気持ち悪い」 「不潔、汚い」 「黒くて大きい」 などが多い気がしますが、この子なら動きもかわいいし、綺麗だし、小さいので、嫌いにならないですよね...?

Excited to publish our population genetic analysis of three subterranean cockroach species (#Nocticolidae)! The Pilbara subterranean habitat appears to be conducive to gene flow for these tiny roaches, contrasting high endemism in other taxa. https://t.co/SV0KWPkIO3

Aim There has been growing interest in non-cave subterranean habitats and their influence on the evolution of troglomorphic (i.e. ‘subterranean adapted’) species. Studies on the diversification of...

Reparations for global climate justice? In this new paper we quantify the compensation that over-emitting countries may owe to the rest of the world for the appropriation of atmospheric commons. Out today in Nature Sustainability, with the brilliant @AndrewLFanning. 🧵

New work from @mikeletnic, Mathew Crowther, Heidi Parker, Elaine Ostrander and I in @molecology finds most DNA tested wild dingoes were pure. Prior DNA studies frequently misidentified pure dingoes as hybrids. https://t.co/FTrKsyRg8H

It was so much fun learning how to incorporate comedy into my science talks. As someone who has historically found public speaking challenging I can’t believe I actually enjoyed this! Thank you so much @ScienceTalksSyd
Native-cockroach guru @tobykovacs had the audience in stitches at the @Syd_Comedy_Fest 🪳 Interested in giving this a go? Our EOIs have just opened! Speakers will be selected for #scienceweek & @sydneyfringe It only takes 1 min: https://t.co/o8n7foV7SU

White plume moth, Pterophorus pentadactyla. A fascinating looking butterfly from the Pterophoridae family. The deeply split wings that are reminiscent of bird feathers are characteristic. The rear wings are split three times and the front wings split twice.

Really excited (+nervous) to have submitted my 1st 1st-author paper! We report an extreme acceleration of substitution rates in the mito genomes of “cave” cockroaches (#Nocticolidae) and highlight the challenges of estimating evolutionary timescales when rates vary! Preprint 👇
