I'm very excited to share that today is my last day working at UC Berkeley before I start my new position at @arcadiascience.com next week! It has been a pleasure working as a postdoc in so many amazing labs along side amazing scientists, and I can't wait to start this new chapter!

I am recruiting PhD students to join my lab at MSU starting Fall 2026! Please spread the word and reach out if you are interested and/or want to learn more!

I am thrilled to announce that in January 2026 I will be starting my own lab at NYU Biology! Soon enough I will be recruiting postdocs and students! Please reach out if you are interested with a CV and description of your research interests, or if you know of people who could be interested! 🧬🗽 🦊

Ryan, @rishidekayne.bsky.social et al. present six new chromosome-level genome assemblies for Poeciliidae, providing a foundation for studies on convergent evolution, repeat content, and demographic history. 🔗 academic.oup.com/gbe/article/17/6/evaf111/8169767 #genome #evolution

Dynamics of a supergene. A study of the BC supergene in wing color morphs of the African monarch #butterfly by @rishidekayne.bsky.social &co reveals dynamic evolution of #supergene haplotypes, fueled by incomplete recombination suppression 🧪 @plosbiology.org plos.io/3DiFhnL

Happy that this paper - www.biorxiv.org/content/10.1... - was accepted at Mol Ecol Res and excited about the promise of this technology to measure pop sizes for such elusive species as snow leopards + learn about at least 1st-degree relationships + beyond? Congrats to Katie Solari and other authors!

Very excited to share our latest paper "Evolutionary Rate Shifts in Coding and Regulatory Regions Underpin Repeated Adaptation to Sulfidic Streams in Poeciliid Fishes" 🐟 academic.oup.com/gbe/article/...

Thrilled to share a new lab pre-print from graduate student Tris Dodge! Tris & co elegantly uncover the genetic underpinnings and fitness consequences of a sexual mimicry polymorphism in Xiphophorus birchmanni: www.biorxiv.org/content/10.1...

Excited to share our review paper "Why Do Some Lineages Radiate While Others Do Not? Perspectives for Future Research on Adaptive Radiations" which is now online here: cshperspectives.cshlp.org/content/earl... Check it out for all things adaptive radiation! 🐟🦎🌿🦋

Hi everyone! It's about time I introduced myself - I'm Rishi and I'm doing a Postdoc at UC Santa Cruz working on adaptation genomics in Poeciliid fishes and Danaus butterflies. I'm particularly the role(s) of structural variation in evolution! 🧬 🧪
