Thanks, Dr. Navarro, for sharing your journey and insights with us! #LatinxInScience

Honored to receive the 2026 R.R. Bensley Award in Cell Biology from the @anatomyorg.bsky.social 🏆 Excited to keep exploring how metabolism, genetics, and epigenetics shape gonadal development and cell differentiation 🧬Grateful to my mentors, collaborators, and lab mates who made this possible.

For this festive season, I’m sending friends and family something a little different: postcards straight from the microscope. 🔬

Featuring my hiPSC Christmas tree from last year and a hiPSC colony turned into a festive bauble, with wishes for a season that’s festive at every scale. 🎄

Are you going to SICB in Jan2026? I can't but I'll be there in spirit with these plates I am donating for the Division of Invertebrate Zoology Libbie Hyman Auction. Show up and support student travel funds by bidding for them! Featuring #membracids #acoels #cnidarians #rotifers @sicb.bsky.social

🎄 Day 1 of the 24 Days of Development ✨🧬
This study shows how different fixation methods (PFA vs. TCA) change what researchers can visualize in chicken embryos using HCR or IHC. 🔍🐣🔬 doi.org/10.1016/j.yd...

🎄✨ Introducing 24 Days of Development!
Each day we’ll highlight one of 2025’s most influential papers published in Developmental Biology, the official journal of the Society for Developmental Biology.
Follow along! 🧬❄️🌟 #DevBio

I can’t believe it’s already been a year! 🎉 Grateful to share this initiative with such an amazing group of Latinx scientists in developmental biology 🙌 More to come! ✨

Lovely work by @martinestermann.bsky.social and colleagues from the Capel lab! Together with our recent work (www.biorxiv.org/content/10.1...), this really makes a strong case that lactate is crucial to supporting male germ cells in vivo - from flies to mammals.

🚨 New preprint alert! 🚨
Excited to share the preprint that marks the beginning of my journey into the world of metabolism! 🍭🧬
A new chapter exploring how metabolic pathways shape gonadal development.
There’s more to come, stay tuned!
