SHARMA LAB
Welcome to the Sharma Lab! Our research broadly addresses macroevolution of invertebrates through the lenses of phylogenomics, historical biogeography, and comparative development, with emphasis on arthropods.
This body of work integrates three avenues of inquiry:
(1) How is biodiversity distributed in time and space?
(2) How do geological phenomena affect the shape of biodiversity over time?
(3) What are the genetic mechanisms that underlie body plan diversification?

Lab News & Events 2018 (updated 8 April):
8 April 2019: Congratulations to Emily Setton on winning the National Science Foundation's Graduate Research Fellowship Program award! This predoctoral fellowship supports Emily's work on the developmental genetics of spiders.
28 March 2019: Our first collaboration with Efrat Gavish-Regev's lab (Hebrew University of Jerusalem) is accepted for publication in Invertebrate Systematics! We described a blind species of armored harvestmen (Laniatores) from a cave in Israel. Congratulations to all the students on the paper: Shlomi Aharon, Audrey Crawford, Keyton Friske, and Guilherme Gainett!
1 March 2019: Congratulations to Dr. Carlos Santibáñez López (former postdoctoral fellow and research associate of the lab) on the publication of his new scorpion phylogeny in Molecular Phylogenetics and Evolution! Carlos' phylogenomic work reveals two new superfamilies of scorpions, Vaejovoidea and Superstitionoidea. Check it out here.
15 February 2019: Many congratulations to Emily Setton and Guilherme Gainett on winning the best student poster and second place prize for oral presentation, respectively, at the 21st International Congress of Arachnology in Christchurch, New Zealand! Emily presented her work on the morphogenesis of spider spinnerets and Guilherme on the evolution of antenniform appendages in Amblypygi.
14 February 2019: Congratulations to Dr. Jesús A. Ballesteros on the publication of his work in Systematic Biology! Jesús' phylogenomic study reveals that arachnids are not a monophyletic group--horseshoe crabs are in fact derived, aquatic arachnids! Check it out here.
6 February 2019: Congratulations to Stephanie Schmidt on the publication of her work in Invertebrate Systematics! Stephanie led a team of US and Filipino scientists in describing the first Tithaeidae (a family of harvestmen) from the Philippines. Check it out here.
3 January 2019: Welcome to John Zern, a new undergraduate in the lab! John joins the spider crew this semester to work on the development of arachnid eyes.
1 December 2018: The lab bids fond and heartfelt farewells to Dr. Carlos Santibáñez López! After two wonderful years in the lab, Carlos is pursuing the phytogeography and evolution of Solifugae (camel spiders) with Professor Matt Graham at Eastern Connecticut University.
14 November 2018: Many congratulations to Carlos Santibáñez López on the publication of his work, using the shape of venom molecules as a phylogenetic character! Carlos has led a team of collaborators both here at UW and at the University of North Carolina-Charlotte to achieve this integrative work. The paper is published here on PeerJ.
12 November 2018: Congratulations to Guilherme Gainett on winning the Laudier Histology award for attending the International Congress of Arachnology! Guilherme, as well as Andrew Ontano and Emily Setton, will present symposium talks on arachnid development.
15 October 2018: Welcome to new undergraduates Josephine Hall and Mahad Siad!
17 September 2018: Congratulations to Logan March, Rachel Smaby, and Emily Setton on the publication of their work on antennal and leg patterning in insects! The work appears here.
22 June 2018: Congratulations to Emily Setton on winning an NSF travel award to attend the GIGA III meeting in Curaçao! Emily will be presenting her work on the use of differential expression tools to analyze functional experiments in spiders.
22 May 2018: Our collaborative work on a homeotic scorpion mutant from Asia has just been published in BMC Evolutionary Biology! This report constitutes the intersection of natural history, paleontology, and development in scorpions.
18 May 2018: Our lab has just published the first transcriptomic analysis of pseudoscorpion venom! Many congratulations to Carlos Santibáñez-López, who led the bioinformatics, and Andrew Ontano, who collecting this material on his first field trip with Mark Harvey in Western Australia last summer!
15 May 2018: The written exercise of the course Zoology 957 (Topics in the Evolutionary Developmental Biology of Animals) has been profiled in spring 2018's newsletter of the Writing Across the Curriculum program. Check it out here!
11 May 2018: Congratulations to Guilherme Gainett on winning the International Society of Arachnology's Jan and Oscar Francke Award! This grant support Guilherme's efforts to pursue the study of leg elongation in whip spiders (Amblypygi)
9 May 2018: Congratulation to Emily Setton on winning an American Arachnological Society research award! Emily will be traveling to Colorado to collect the embryos of mygalomorph spiders this summer.
5 May 2018: Congratulations to Guilherme Gainett on (a) winning a UW-Madison travel award for attendance at the GIGA meeting in Curaçao, (b) winning the Davis research grant for developmental genetic study of leg elongation in whip spiders (Amblypygi), and (c) the acceptance of his paper in the Journal of Morphology. All in one week!
26 March 2018: Congratulations to Emily Setton on the publication of her undergraduate research in the Proceedings of the National Academy of Sciences (PNAS)! This work of (mostly) chelicerate evodevo features data from spiders, scorpions, harvestmen, centipedes, horseshoe crabs, onychophorans, and pycnogonids. Check it out here.
2 February 2018: We have just published the first phylogenomic dating of the scorpion tree of life! Check it out here.
24 January 2018: Congratulations to Jesus Ballesteros on being awarded a National Geographic Society grant! Dr. Ballesteros will be conducting fieldwork and population genomic surveys to investigate the evolution of cave dwelling arachnids in Israel.
