Dr. Aaron Noell

Dr. Noell is a technologist working in the instruments division at JPL. Currently, he is developing instruments for the assessment of habitability and the search for extant life on other bodies in the solar system. His research interests also include the radiation chemistry of low temperature ices, and the impact of that chemistry on habitability/bio-markers in the ices. His instrument development has focused on microfluidic implementation of capillary electrophoresis, ion chromatography, and selective electrochemical detection (e.g., ion selective electrodes). Additionally, he has worked to develop sample handling and extraction techniques compatible with microfluidic instruments, such as subcritical water extraction. Previously, he was an NPP Postdoc at JPL working on instrumentation to detect bacterial spores for both biodefense and astrobiology purposes, and received his Ph.D. in Chemistry from Caltech in 2010.
