 Hi there, I am Iris Rojas. I am a geology professor at College of the Desert in California. So let me tell you just a little bit about what I do other than teaching. So my specialty is geochronology and I also study igneous deposits, volcanic deposits or igneous rice, the deposits that result from a violent volcanic eruption most of the time. So how did I combine my love of dating rocks, putting an age to them and volcanoes? So what I do is that I put constraints on the eruption age of ancient volcanoes. I look at their deposits and I can tell you the chemistry of the magma or the lava that erupted and I can also tell you how old it is or how long ago it erupted. So that's what I did in terms of my research. Most of my days now are spent in a classroom, a lab or outdoors leading field trips. It's so nice to meet you. I hope you enjoy geology as much as I do and I'm just glad to share my story with you all. Have a great one!
