Chasing fireballs and the evolution of our solar system with Professor Gretchen Benedix

We've spoken about indirect career paths, but Professor Gretchen Benedix calls hers the pinball method, starting on a course that could change direction when she strikes something that she'd like to delve more into. This method has served Gretchen well and has given her opportunities to work with Dr Sally Ride, the first American woman in space, chase fireballs over the desert, hunt meteorites in Antarctica, and even get an asteroid named after her.

Join us as we speak with Gretchen about her journey to astrogeology, discovering how the solar system evolved, and the Desert Fireball Network.

About Professor Gretchen Benedix

Gretchen Benedix is a Professor (and former Australian Research Council Future Fellow) in the School of Earth and Planetary Sciences at Curtin University. She is also a member of the Space Science and Technology Centre, the largest research group dedicated to Planetary Science in the southern hemisphere.

She is a fierce STEM and Women in Science advocate and takes her responsibility as a role model very seriously. She uses her work to inspire young people and pass along her passion for understanding our Solar System.

Gretchen’s research interests lie in the study of meteorites to understand and unravel the evolution of the Solar System. She and her team are currently interested in using machine learning techniques to extend our ability to interact with big datasets, specifically looking at the numbers of craters on other planetary surfaces.

Gretchen wants to understand how the Earth fits into the history of the Solar System.

… And also, she love rocks…

Gretchen has a broad educational background in Geology, Engineering, and Physics, which lets her pull together multidisciplinary ideas to unravel the mysteries of the rocks.

She also loves science communication and has had the opportunity to work at two world-class museums as a planetary scientist, cosmic mineralogist, and astro-geologist, where Gretchen had the pleasure of sharing what she does --- It’s just one of the many aspects of her job that she loves - to be able to get other people, especially young folks, excited about studying our solar system and our place in it.

Veterinary policy and mental health with Dr Lydia Pethick

A common misconception about veterinary sciences is that it’s all about puppies and kittens, but that’s not always the case. Like other care providers, vets can have it tough in the service of the community and there is a lot of active work being done to ensure the vet industry, its people, the community, and not just the animals, can thrive. Join us as we speak with Dr Lydia Pethick, veterinarian, motivational speaker, and television presenter about working in policy and biosecurity as a vet, the state of mental health and wellbeing in the veterinary industry, and the actionable things we can do to positively impact our mindset and prevent burnout.

Building compassionate tech, and advocating for diverse voices with Bec Nguyen

For many of my guests, the careers and fields that we're in now didn't exist or were just newly conceived when we were at university. So those indirect paths I often speak about were just a matter of course. Bec Nguyen is the director of Upbeat Digital and a specialist in UX in digital health. Join us as we speak about her winding path to User Experience Design and design thinking as it grew as a space, building compassionate tech, and advocating for diverse voices no matter what industry you're in.
