Hello there!

My name’s Frank, and I’m an independent analytical/research mineralogist currently based in Tucson.  I’m affiliated with the University of Arizona, where I work with faculty and students in the Economic Geology group in an essentially adjunct “mostly-researcher/occasional-instructor” position. As a hardcore introvert, I certainly value my thoughtful alone time sitting in front of humming high-tech instruments and collecting data; indeed, it’s an ideal work environment that meshes well with my introspective personality. Still, my job does require me to periodically interact with other humans, and yes, I have to admit, I actually do get real joy and fulfillment from teaching and mentoring students, particularly when I’m working one-on-one or in small groups. Given my preference for those smaller, more intimate academic settings, it then might seem somewhat ironic that my enthusiasm for education also extends more expansively toward outreach. To that end, I’ve put together this website to share my passion for mineralogy & petrology with the global online community. So whether you’re a professional geologist, a student, a mineral collector, or simply someone with a curiosity and appreciation of science & nature (or even if you’re just looking for one of my recipes, or want to check out the photos from my last trip), hopefully you’ll find something among these pages that is both interesting and informative.

Although the site is still very much “under construction”, feel free to poke around… at this point, most of the pages have some content, and I’m routinely adding new content, and exploring ideas for new pages & general site improvements.

I’ll be hosting my Spring 2018 petrology class lecture notes on this site (on the “how to” PDFs page) for simplicity and because I don’t want to deal with D2L. To avoid any appearance of conflict of interest, I’ve temporarily disabled the donation and digital books pages here. From October 2017 to May 2018 these pages will be unavailable, and will be re-activated sometime in mid-May 2018 after I post final grades. Thanks.
