🎉 New research! Microplastics don’t just pollute; they carry harmful chemicals. In #Celegans, this combo reduced lifespan & reproduction. This study was led almost entirely by undergraduate researchers at StMU 💙💛 🔗 www.mdpi.com/3615716 #microplastics #NIHfunded #science #undergraduateresearch

“Approach difficult conversations with empathy.” Important words from Crystal Rogers at #worm25
Reminders to myself and others
• Apply often, apply broadly, and diversify funding.
• Fight misinformation about science and scientists (publicly and/or privately).
• Use social media for advocacy, branding, and SciComm- expand your network.
• Maximize your resources- learn how to do science on a budget.
• Bring your whole self to science (when you can safely).
• Celebrate All of your wins, big and small!
• Always keep your options open and approach science and academia with flexibility.

I’m feeling hopeful and inspired at Pamela Padilla’s #worm25 talk. We have work to do. We should be kind while doing it.

I’m so exited for #worm25! It’s already off to a great start with the teaching workshop. If you’re interested in how worms respond to environmental stress from microplastics + environmental chemicals, come by my group’s poster, 858A on Sunday night! #undergraduateresearch #PUI

I'm incredibly excited to share my lab's first pre-print! www.researchsquare.com/article/rs-6... We show that microplastics (MPs) mediate the delivery of a plasticizer, di-butyl phthalate (DBP), to C. elegans & alter reproduction and lifespan. 1/6 #Microplastic #Celegans #undergraduate #Science

“a key feature of this community became abundantly clear: Worm people tend to help one other.” This statement is true and why I love the worm community. Despite the chaos, I will keep training young scientists, in the ways of this incredible community. 💪🏼💕🥼🔬

If on some days you are tempted to give up and throw in the towel - DON'T! Don't let them win. Science on! Try to make it work. We can do this!

Last week St. Mary's University hosted the 2025 Research Showcase. Students from my group shared their projects on microplastic toxicity with posters and oral presentations. They have accomplished so much and it was great to see them shine. THIS is what scientists look like!

It’s homecoming week at St. Mary’s and my research group went all out to decorate the lab door. I love their creativity. 🏜️🌵👩🏽‍🔬 The future of science is still bright. #Celegans #Science #StMU

The administration undermines efforts to reduce plastics. But plastic never will be disposable, and neither are the people it poisons.

Im so proud of Chiara Maldonado for winning a poster award at #ABRCMS2024. She’s a force in the lab & great scientist. Keep an eye out for her, she’s looking for summer research positions and PhD programs in the near future- she’s going places! 🤩 #science #womeninstem #stmu #celegans #nanoplastics

My students have an ABRCMS meeting feed just for our group. The amount of joy I see in their pictures and posts is 🥰😍❣️ This gang is amazing. See for yourself (5 of the 19).
