With more than four decades dedicated to science education and a lifelong fascination with the cosmos, Dr Keith Treschman brings the wonders of astronomy vividly to life through engaging storytelling, deep scientific expertise, and infectious enthusiasm. A highly accomplished educator and astronomer, Keith holds Bachelor’s degrees in Science, Education, and Arts, alongside a Diploma in Education, Master’s degrees in both Education and Science (majoring in Astronomy), and a PhD focused on Astronomical Tests of General Relativity — placing him at the intersection of theoretical physics and observational astronomy.
Throughout his distinguished career, Keith has inspired generations of students and lifelong learners through innovative science communication. He has operated the Sir Thomas Brisbane Planetarium, delivering immersive presentations to both school audiences and the wider public, and played a key role in establishing the Dorothy Hill Observatory — a pioneering robotic observatory designed to support astronomical learning and research for secondary students.
An award-winning educator, Keith received the prestigious Gold Medal for Excellence in Science Teaching from the Queensland Science Teachers Association in recognition of his outstanding contribution to science education. Over the past forty years, he has hosted countless astronomy viewing nights, guiding audiences beneath the night sky and deepening their appreciation of the universe.
A passionate traveler who has visited all seven continents, he brings a global perspective to his talks — connecting the night skies above the world’s most remote places with the scientific stories that shape our understanding of space and time.
Guests can look forward to inspiring lectures exploring astronomy, cosmology, and the profound questions of our universe, delivered with clarity, humor, and a genuine passion for discovery.
Dr. Keith Treschman will be a Special Guest on our Arctic Golden Autumn & Northern Lights voyage, departing 18 August 2026 & our Northern Lights Explorer voyage departing 2 September 2026.
