A productive summer


This summer has been especially productive. Collaborators and I submitted several manuscripts on diverse topics, including species delimitation in scorpions using genome-wide SNP data, comparative analysis of venoms and biological activities within two groups of rattlesnakes, species delimitation and biogeography of a widespread group of birds, and systematics and biogeography of an alligator lizard.

50th peer-reviewed paper published

This month my 50th peer-reviewed paper was published, an exciting milestone in my career. Collaborators and I also unveiled a genomic toolkit for arachnids featuring hundreds of conserved DNA regions (ultraconserved elements or UCEs) that will allow targeted sequencing of any species in the arachnid tree of life [preprint]. The probe set we developed will soon be publicly available on http://ultraconserved.org
