I attended the annual RCSA Fellows Conference in Tucson, AZ, a bittersweet end to my 3 years in the program. Thanks to @eileenms.bsky.social for her leadership, and to my fellow 2024 RCSA Fellows for the encouragement, with support from @rescorp.org . Can't wait to see where our paths cross next!

Awesome to see this published after years of hard work. Proud twin moment! 🤩🥳 www.cell.com/cell/fulltex...
New issue alert! 👉 cell.com/cell/current On the cover: Brann et al. demonstrate that each olfactory sensory neuron selects one of approximately 1,000 receptors to express based on its spatial position within the olfactory epithelium, thereby creating a precise and stereotyped receptor map
I’m thrilled to share that I’ll be joining Bryn Mawr College as a tenure-track Assistant Professor of Chemistry in January 2027! I’m excited to teach Bryn Mawr students, build the Brann Astrochemistry Group, and continue mentoring and empowering women and gender-diverse students in STEM. 🚀🌟
Congratulations to the 2026 Fellows! 🥳 RCSA’s support was truly invaluable during my time on the job market, and I’m excited to meet everyone in Tucson this June and welcome a new cohort into this community. #RCSAFellows
RCSA has selected a new class of outstanding postdoctoral scholars in the third year of the #RCSAFellows initiative, which aims to increase faculty excellence in the physical sciences through a multiyear program of job search preparation, professional development, and community building.

Successful #ACSSpring2026! I had my first meeting as a member of the Committee on Economic and Professional Affairs (CEPA), received my plaque for the 2025 ACS Astrochemistry Subdivision Outstanding Dissertation Award, and enjoyed catching up with friends and colleagues!
The AAS Laboratory Astrophysics Division (LAD) is honoring Julia Santos for her PhD thesis at Leiden University, "Transformation and sublimation of interstellar ices: insights from laboratory experiments and astronomical observations." 🔭 aas.org/posts/news/2...
Really honoured to be a part of this cohort!! This is such a unique award that helps early career faculty enhance their research programs but innovate in teaching and learning!
RCSA welcomes 24 early career teacher-scholars in chemistry, physics, and astronomy as recipients of its 2026 #CottrellScholar Awards. Each awardee receives $120,000. Congratulations to this exceptional class!

My first paper with the Öberg astrochemistry group! In laboratory ice experiments, we find that oxygen atoms react with methyl cyanide to form methyl isocyanate. This work sheds light on chemical evolution in space & the origins of life’s building blocks. doi.org/10.3847/1538...

My advisor, Karin Öberg, says you’re ready to graduate once you start dressing like your advisor. It’s therefore fitting that yesterday we matched (unplanned) during my dissertation talk :) Excited to share I defended my PhD & will be going to @mpe-garching.bsky.social to work with Paola Caselli!
At #LINO25 I shared my research, got thoughtful advice from Nobel Laureates, and joined Frances Arnold for a science walk. I’m feeling inspired, energized, and excited to stay connected with this international community. Thank you @tamu.bsky.social and @nationalacademies.org for sponsoring!

A few photos from my week at #ACSSpring2025. Reconnecting with members of our #CASFutureLeaders community is always so inspiring. Thanks to all who tracked me down (and made me laugh) in San Diego!
En route to San Diego for #ACSSpring2025. I’m looking forward to attending my first Committee on Economic and Professional Affairs (CEPA) meeting tomorrow. I’m also giving a presentation in the Astrochemistry Symposium in honor of Eric Herbst on Tuesday at 11 AM ☺️
