I have 5 years experience conducting respirometry experiments to determine the degradation rates of bio and petroleum-based polymers (particularly PHAs) under different environmental conditions. I conduct experiments utilizing a Micro-Oxymax respirometer following ASTM standards for biodegradabilty, as well as an automated biological oxygen demand sensor (autoBOD) which is used for rapid analysis. In addition to laboratory-based respirometry, I also conduct in situ degradation studies based on mass loss, and I developed a custom flow through incubation system which mirrors in situ conditions but allows for testing in the lab.
