Marie Curie Lecture Series - UOW Science Space

Join the University of Wollongong's Science Space for this public lecture presented by the Australian Institute of Physics's 2026 Women in Physics Lecturer as part of the Marie Curie Lectures.

In 2017, the Universe spoke in waves and light—ushering in a new era of astronomy. In this lecture, Dr Karelle Siellez weaves together sound, art, and astrophysics to explore the story of gravitational waves and the collisions that create the elements we are made of. Through "multi-messenger" signals like kilonovae and gamma-ray bursts, we'll uncover how the cosmos communicates its most violent events. Blending scientific insights with creative expression, this journey reveals how listening to the Universe—and protecting its silence—can connect science, nature, and humanity.

Dr Karelle Siellez is an astrophysicist and lecturer at the University of Tasmania. A specialist in multi-messenger astronomy, she contributed to the first detection of a gamma-ray burst and gravitational waves from the same cosmic event, recognised with the 2017 Breakthrough Prize. She is also an award-winning science communicator who integrates art, sound, and storytelling into her work, making complex astrophysics accessible and inspiring. Karelle has lived and worked in France, the USA, and now Tasmania—where she divides her time between telescopes, classrooms, and the wilderness of sea and forest.
