Science has become a way for me to experience and understand the delicate balance of the world around us.
I am a post-doctoral researcher working in the Brzezinski Lab at UC Santa Barbara (California).
I use silicon isotopes to study the silicon biogeochemical cycle and its influence on the biological pump of carbon in the modern and past ocean with a special focus on polar regions.
