Arnaud is a gene-nerd and evo-devotee often found day-dreaming in the lab about color pattern landscapes and tropical cloud-forests.
He is dedicated to using genome editing in non-traditional laboratory animals, establishing butterfly and moths as models in developmental biology and genetics, and integrating our general knowledge of genotype-phenotype relationships in nature via Gephebase.

GRADUATE STUDENTS
|
Amruta is interested in the molecular basis of diversity in the animal kingdom. Currently studying the landscape of Wnt signaling in the developing wing and the role of Hox genes in wing patterning, Amruta eventually wants to investigate the role of the same developmental pathways in other animal lineages. Other than excessive pipetting, Amruta enjoys reading and hiking.

Ling is mainly interested in the developmental genetics and molecular mechanisms underlying pattern formation. Using butterflies and moths as study models, she is investigating the developmental basis of wing patterns by expression and functional analyses. Other than spending time in the concrete jungle, she enjoys hikes in green spaces under the sun and loves cats.

Christa is interested in harnessing the added economic and scientific values in manipulating prolific organisms for human endeavors, from cell-based biosensors and bioreactors, to insect models. Currently, she is on a mission to establish the pantry moth, Plodia interpunctella, a grain pest, as an animal model for lepidopteran CRISPR works. She is obsessed with fountain pens, inks, and all things stationery.

STAFF
|
Joe is interested in the evolution, development and genetics of butterfly wing patterns. During his PhD he studied the wing patterns of Heliconius butterflies with population genetics and transcriptomics. Now, he is working on the mechanism of Wnt signalling in the developing wing, as well as the genetics of pattern differences between a sympatric species pair of Colias butterflies. He enjoys watching movies and long walks in the park.

Anyi is an evolutionary biologist investigating how development underlies morphological diversity. For her postdoctoral work, she aims to dig into the molecular mechanisms setting color patterns driven by the WntA pathway in butterflies, using a mix of functional genomics and developmental genetics. In addition, she is part of the team building genetic tools in the Indian mealmoth, Plodia interpunctella. She enjoys mentoring students, watching stand-up comedies, and coloring with her kid.
|
|
Luca is an evolutionary biologist interested in how development underlies morphological diversity. His postdoctoral research addresses how genes evolve to regulate differences in the wing patterns of butterflies and moths. Luca is also working on developing transgenic tools in the Indian mealmoth, Plodia interpunctella, with the hopes of developing a developmental model to address specific questions on scale development and evolution.

Donya is interested the genetic and developmental basis of diversity in the animal kingdom. The vast array of features that are programmed during development include unique morphologies and innate behaviors that animals are born with. She spent her PhD studying the evolutionary origins of novel morphologies, particularly a male genital structure in the fruit fly, Drosophila melanogaster. Now, she is interested in understanding how complex developmental programs specify innate behaviors using the pantry moth, Plodia interpunctella. Other forms of complexity she enjoys are the chocolatey notes of coffee and the “sweet science” of boxing.

UNDERGRADUATE STUDENTS
|
Kelsey is currently assessing the functions of HOX gene regulatory elements in butterfly development using CRISPR technique. Her interest in the insect HOX gene developmental pathways correlates to her desire to more greatly understand the pathways of HOX genes in human embryonic development. When she is not in SEH, she is probably at a coffee shop, a museum, reading a good book, or watching Game of Thrones with her friends.
|
|
Alexis is interested in the developmental interactions that outline butterfly color patterns. She is currently investigating the role of regulatory elements and their influence on the WntA pathway, and examining the phenotypic results on butterfly wing patterns. When she is not praying to the PCR gods or tending to caterpillars, she can be found drinking lots of coffee, running, or re-watching the Harry Potter movies.
|
|
Kiana is interested in evolutionary neural networks and its integration with human behavior and characteristics. She is now interested in how nostalgia affects the human brain and if it has any evolutionary benefit. In the Martin Lab, she focuses on how genes affect phenotypic variations as well as a closer look into mutational mechanisms. She loves taking pictures of flowers and watching documentaries.
|
|
Shakthi is interested in the development of wing pattern and formation in butterflies. He is currently investigating the role of sre-14 gene in Colias butterflies and examining the molecular mechanisms behind these changes. Outside of working at the lab, he enjoys playing chess, watching sports, or going on late night runs to Captain Cookie.
|
|
Christian is interested in the signaling pathways behind the development of patterning in butterflies. Currently he is investigating how the WntA pathway drives coloring patterns and the molecular mechanisms behind it. Outside of the lab, he enjoys listening to music, rowing for the GW crew team, and watching sports.

Vince is studying the evolution and genetic basis of a sexually ornamental type of butterfly scale found in the family Pieridae. He uses ancestral state reconstruction and phylogenetic comparative methods to estimate the macroevolutionary trends of the scale type and he uses population genetics combined with CRISPR methods to uncover a locus necessary for the development of this scale type in Colias eurytheme. He is probably reading or taking long walks across chromosomes.

Anna Ren is broadly interested in how structure can influence material properties. Currently, she is working on how scale cells can use colorless chitin to appear as a spectrum of different colors, from iridescent blues and ultraviolets to metallic gold and silver. When she is not turning everything in Illustrator/Photoshop into a mask, she enjoys painting, baking, and walks in the city.

Olaf Corning is fascinated by how cells organize to form complex structure and how DNA acts as a dynamic driver of state. He is interested in using disparate lines of thinking to understand and engineer biological machines. As an undergrad, he is using CRISPR mutagenesis and machine learning to discover and describe key developmental cis-regulatory modules. He has outside interests but he’s out of spa--

Natalie D’Souza is interested in learning more about the relationships between genotype and phenotype.
