I've done similar profiles for the researchers in Paris at the Museum natioinal d'Histoire naturelle (here)! I think this gives everyone a bit of insight into the many different crew members which staff the various roles in the big research seen in scientific papers. And Dr. Tim O'Hara's lab has had a good week for "big research paper drops" with more to come!!
Just as a refresher though.. Here's a pic with the BIG project that Tim O'Hara's lab has been working on for the last several years: the BIG ophiuroid (aka the brittle and basket star) phylogeny! aka the "family tree" of the ophiuroids!
As I've mentioned previously, the new phylogeny is a BIG deal. It involves a group with over 2000 species which has been a taxonomic headache to scientists for over 100 years. Their research has literally turned this whole field on its head! (if brittle stars had a head!)
The tree clarifies which groups show support for being "real" and elaborates on how different brittle star and basket groups are related to one another. It will almost DOUBLE the number families!!!
The tree was made using a phylogenomic data set. This is different from a lot of the molecular trees made in the last 20 years because it includes a whopping 425 genes and over 60 taxa! (other trees generally use only 3 to 10) You can see the big paper as published in Current Biology here.
The Echinoderm researchers at Museum Victoria includes a diversity of workers!
1. Dr. Andrew Hugall
Where Tim O'Hara provides the "Ophiuroid Taxonomy and context", Dr. Hugall is the phylogenetics and analytical guru part of the "Big Ophiuroid" team. Although he is currently working on marine invertebrates, he worked previously on birds, discovering "Accelerated speciation" in highly colorful birds, a paper which was published in Nature in 2012. You can see that here.
2. Lupita Bribiesca
Lupita is a PhD student at the University of Melbourne and got her undergraduate degree from the Universidad Nacional Autónoma de México. She's not only very proficient in computer coding and analysis but she's already a prolific author in echinoderm systematics! Especially in anchialine cave echinoderms!
3. Skipton "Skip" Woolley
I featured Kate Naughton's work on the blog back in 2009 when she and Tim O'Hara discovered a brooding "cryptic" species of the Australian Biscuit Star Tosia using molecular tools to understand the relationships of Tosia australis along the Australian coast. (see this story here)
Since then Kate has received her PhD and continued to do her awesome work combining ecology, taxonomy and molecular phylogenetics at Museum Victoria.

5. P. Mark O'Loughlin and Deep Sea Sea Cucumbers
One of the most established echinoderm researchers at Museum Victoria was actually Tim O'Hara's original mentor!
Mark O'Loughlin has been a fixture of the "marine invertebrates" scene in the Melbourne/Victoria area of Australia for decades. He's published a huge volume of work on echinoderms, including sea stars and sea cucumbers. Here's his profile at ResearchGate!
here's a sclerite from a new species of "sea pig" (Family Elpidiidae) that Mark is currently working on from the the Great Australian Bight (979 m)
My thanks to the Museum Victoria for my visit! About 1000 specimen lots identified!
