WELCOME TO MY PERSONAL WEBSITE!

I am Jeff (he/they), a Scientist in the Interface Geochemistry section of the GFZ Helmholtz Centre for Geosciences. My current research focuses on molecular-scale mineral-organic matter interface biogeochemical processes in polar terrestrial and aquatic ecosystems.
In addition, I am also studying the formation and transformation of iron-bearing minerals, and their influence on the cycling of nutrients (e.g. P, Si) and toxic elements (e.g. As, Cr) in oxygen-poor modern and ancient environments. I combine several analytical approaches from geochemistry, materials and analytical chemistry, and nanoscience to gain better understanding of iron biogeochemistry at the nano- to atomic-scale.
Feel free to connect with me with my socials (BlueSky, X), or drop an e-mail!

As a queer, POC and 1st-Gen scientist, I am a huge advocate LGBTQIA+ visibility, and diversity in STEM! 🏳️🌈 Check out my People’s Profile courtesy of the European Association of Geochemistry (EAG) Diversity, Equity and Inclusion (DEI) Committee.
Together with Dr. Claire Treat, Donovan Dennis and Mackenzie Baysinger, we have recently started the lunch club “Out on the ‘Berg” (aka Rainbow lunch) for LGBTQIA+ folks and allies at the Telegrafenberg scientific institutes GFZ-RIFS, AWI and PIK. The OOTB core group also recently teamed up with the GFZ Diversity Team to launch the first “Pride on the Hill” event last July 2024.
Please also visit Pride in STEM and LGBTQ STEM Berlin if you want to know more about how we can increase LGBTQ+ visibility, and create safe spaces for LGBTQ+ people in STEM.
