Meet up-and-coming scientists and learn about questions at the forefront of research today in this series of short talks.

2:00–2:30 pm – The Case of the Immortal Chemicals
Speaker: Ethan Sontarp, Graduate Student with the Sunderland Group

There’s a mystery that needs to be solved: where does invisible pollution go when it is released into the environment? Scientists use chemical fingerprinting to do detective work, uncovering why certain man-made pollutants are so resistant to breaking down and where they like to go. By following this trail of clues, researchers can learn how to stop pollution from entering our food and drinking water. Join Harvard scientist Ethan Sontarp to discover how environmental detective work can help protect the world around us.

3:00-3:30 pm – Learning about the Deep Past from Ancient DNA
Speaker: Daniel Tabin, PhD Student in the David Reich Lab

Writing has only been around for about 6,000 years. This means that the stories of people who lived before that time were never recorded for future generations. Thankfully, these stories are not lost forever. How can we learn about the adventures, relationships, and challenges of people who lived long before anyone ever put words on a page? Join Harvard scientist Daniel Tabin to discover how ancient DNA can help us piece together the lives of people who lived thousands of years ago—and hear about the remarkable stories he has helped bring back to light.

20-minute talk followed by 10-minute Q&A session. Recommended for ages 10 and up.
Regular museum admission rates apply.

Join the Salata Institute at Mignone Center for Career Success for an evening that explores scientific creativity and tangible career opportunities in Denmark. Learn how you can build a meaningful career in a thriving, collaborative research ecosystem through Danish Technical University and Science Hub Denmark. Discover how your next research step could take you to the heart of Europe’s green and bioscience transition. This session features Andreas Worberg, Head of the Center for Biosolutions at Danish Technical University, and Charles More, interdisciplinary thinker and founder of Imaginative Philosophy. Together, they will share perspectives on how cutting-edge bioscience, biomanufacturing, and creative scientific thinking translate into real-world climate and planetary health solutions. Speakers will highlight career pathways within Denmark’s collaborative research landscape, including opportunities supported by Science Hub Denmark, and discuss how researchers can move from early-stage inquiry to applied impact. Attendees will gain insight into how their next research step could place them at the heart of Europe’s green and bioscience transition—working across disciplines, sectors, and borders to address urgent climate challenges.
