Don't Miss Phosphorus Week in November
STEPS will host the Phosphorus Forum November 1-2 and the Sustainable Phosphorus Summit November 3-4
The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research community of diverse and leading scientists that addresses the complex challenges in phosphorus sustainability by integrating disciplinary contributions across the physical, life, social, and economic sciences. The STEPS vision is to facilitate a 25% reduction in human dependence on mined phosphates and a 25% reduction in losses of point and non-point sources of phosphorus to soils and water resources within 25 years, leading to enhanced resilience of food systems and reduced environmental damage.
Lucas Crane, Masters Student - Lucas is a current M.S. student and future Ph.D. student in Environmental Engineering at Arizona State University working under Dr. Treavor H. Boyer, Professor of Environmental Engineering. His primary research interests are in physicochemical characterization and treatment of water and wastewater, including waste-to-benefit reuse of human urine, implementation of urine collection systems, and application of sensing technologies in premise plumbing systems. In his undergraduate research, he designed a novel biocementation process using human urine and calcium-rich zeolites to reduce the costs of reagents and minimize the environmental impact of enzyme-induced carbonate precipitation; this work was recently published in the Journal of Environmental Chemical Engineering. In his master's research, he is investigating the permeation of urea from human urine through reverse osmosis and nanofiltration membranes. In STEPS, he will be continuing his study of urine by investigating the recovery of phosphate from human urine via chemical precipitation and electrochemistry and modeling flows of phosphorus in wastewater distribution systems.Read More
Dr. Ross Sozzani Promoted to Full Professor
We are so excited to announce that Dr. Ross Sozzani is now a full time professor here at our department! The Sozzani lab aims to gain a coherent qualitative and quantitative understanding of stem cell maintenance at the systems-level. Be sure to follow along with her exciting research and check out her bio! Congratulations Dr Sozzani! We cannot wait to see what you have in store for North Carolina State University !
The Global Nitrogen-Phosphorus Imbalance
STEPS investigator and SPA Director Jim Elser continues to lead our understanding of the nitrogen-phosphorus imbalance. The article details how the N/P ratio determines the community structure and function of plankton in lakes. He concluded that lower N/P ratios were associated with faster proteins synthesis and a higher growth rate among plankton.
