Welcome to the Jamaican Geologist YouTube channel!
Here, I explore a wide range of geology topics—with a special focus on Jamaica's unique geology.
A little about me: I hold a Bachelor of Science in Geology and a Masters in Natural Resources Management. As of January 2025, when I launched this channel, I'm six months into my PhD programme in geology. I bring ten years of professional experience with the government of Jamaica, where I worked first as a soils laboratory technician then as an economic geologist. My passion for the geosciences springs from childhood fascination, academic curiosity and industry experience, and I aim to reflect that balance on this channel.
Whether you're a student, a professional, or just curious about the physical world, I hope you find the content here both informative and enjoyable.
