Kicked off #Goldschmidt2025 yesterday by running a super fun workshop to help students write their first fellowship! It was extremely rewarding to facilitate their discussions and see their first draft come together in a few hours!!

Presented at the Future of Volcanology today at #IAVCEI2025
Despite delays from the previous talks & tech hiccups (while we were all starving!!), I’m so grateful for those who stayed till the end with me.
The feedback and support afterwards truly made it all worth it!

Despite the scorching heat and a touch of sushi-induced food poisoning, #IAVCEI25 has been SO MUCH FUN! Old friends, new friends, tons of cool science, and of course, swimming in Lac Léman 🌊
Also kinda loving when people say they know me from Bluesky/Twitter… pls keep it coming 😁💙

And so summer has began!
I had a wonderful time at the Alaska Aleutian in Anchorage last week. Lots of fun science conversations, great new connections, and amazing sights in and around Anchorage!

I did not expect this to get this much attention 🤯
If you like meteorites, come visit us at the Smithsonian National Museum of Natural History!
Not only we have an amazing collection but you are likely to see me sneaking in and out from hidden doors through the exhibits 💁🏻♀️

Brushing off the cobwebs here! 🕸️👋
Spring flew by in a blur: events at the Smithsonian, talks at UBC, UC Riverside, UMD, & a GSW poster at Carnegie (yes, I’ve been talking a lot).
Now bracing for the summer travel + conference sprint. Excited for science, snacks, and hopefully fewer airport delays!

When Solimões and Rio Negro meet, they become the massive Amazon river. But because of their difference in density, they don’t mix right away.
I don’t think liquid immiscibility can get any more clear than that!

The Smithsonian Mineral Science fellows ;)
This crowd is amazing and I can’t explain how much fun (and snacks lol) we have in the office every day.
Glad to be part of this amazing group of young scientists and grateful for all the super inspiring and funny chats we had the past few months!

The Old Rag Granite at Shenandoah National Park… I’ll have to admit I like granites a lot better when I am not struggling to hike them before the sun sets 🥲
Virginia views are always 10/10 tho ✨

Here to share that I recently started a PostDoc fellowship at the Smithsonian Museum of Natural History!
It was an unusual road to get here - but somehow I feel that I am exactly where I should be ☺️ Super grateful to all the fantastic people who have facilitated my way here!
📍Washington DC! 🇺🇸

Yesterday I defended my PhD thesis :) For a while I didn’t think I could do it - it wasn’t easy, but now that I am here, I’m glad I made it this far 🎓☺️

For everyone who’s been using Ti-in-quartz or Ti-in-zircon thermometers, my 2 cents on what to watch out for when constraining the aTiO2 just got published on Geology 😌
