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 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.

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
Top: Topology weightings across chr15 showing how the karamu haplotype is related to the klugii and orientis haplotypes. Upper panel shows three possible rooted genealogical topologies. Second panel shows weights for each topology along the chromosome, smoothed with a 20 kb span. Arrows above the plot indicate the locations of inversions. Third panel shows unsmoothed topology weightings across a 1.5 Mb region corresponding to Inversion 2. Bottom: Ancestry painting across a 100 kb region within Inversion 2, showing ancestry tracts for two homozygous karamu individuals compared to two representative individuals homozygous for the orientis and klugii haplotypes. Coding regions are indicated below the plot, with the candidate gene for background colouration yellow indicated. Green triangles represent the top 10 SNPs for background colour in our GWAS. There is evidence for recombination throughout the supergene region, and specifically in the vicinity of yellow, consistent with the hypothesis that orientis ancestry at this locus (i.e., the B allele) is associated with darker colouration in karamu individuals.

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!
Next-generation snow leopard population assessment tool: multiplex-PCR SNP panel for individual identification from feces
Snow leopards, Panthera uncia , are under threat from numerous pressures and are the focus of a great deal of conservation efforts. However, their elusive nature makes it difficult to estimate populat...

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! 🧬 🧪
