.I’m David Valerio/ I’m a second-year Ph.D. student at Rice University in Dr. Laurence Yeung’s research group where I study marine biogeochemistry.

I develop and apply novel isotopic proxies of dissolved oxygen (O2) and nitrogen (N2) in natural waters to quantify photosynthesis and denitrification in marine settings. To do this, I use ultra-high precision, triple isotope and “clumped isotope” measurements of naturally occurring dissolved O2 and N2 to create mass balances that quantify the rate and amount of biologically produced O2 and N2. The overarching goal of this research is to improve our quantitative understanding of global and regional biogeochemical cycles. After completing my Ph.D., I’d like to move into the startup world to work at the interface between microbiology, stable isotope geochemistry, and chemical oceanography to help solve some of the most important problems facing the world ocean today.

Besides doing research, I read books, lift weights, go to concerts, and evangelize for the greatest city in the world, Houston, Texas. I enjoy reading history, biography, science fiction and philosophical novels. I also blog when I feel like it.

I have a Google Scholar.
