Ryan Greene is a PREP researcher within the Flammability Reduction Group of the Fire Research Division (FRD) at the National Institute of Standards and Technology (NIST). Ryan studied at Cornell University, where he specialized on polymeric materials and materials chemistry. Specifically, his undergraduate research focused on the development of nanofibrous facemask filters from recycled polyester bottles, while his graduate was in the creation of slow-release fertilizer pellets using pulverized glass waste. Ryan is currently involved in the development of the NIST Materials Flammability Database under Dr. Isaac Leventon. This project is designed to support the quantitative prediction of material flammability through the maintenance and analysis of comprehensive data sets from several mg to intermediate scale apparatus. As part of this effort, Ryan has developed test procedures and automated analytical processing scripts for the group’s simultaneous thermal analyzer (TGA/DSC), Flash organic elemental analyzer, and molecular weight apparatus. Collectively, this work is aimed at determining effective thermal decomposition mechanisms for combustible solids and quantifying the average molecular weight and composition of the gaseous volatiles they produce. Outside of NIST, Ryan works as a goalie coach for the Bethesda Lacrosse Club.
