            The profile charts her path from a former undergraduate intern on the GeneSat project to her current research as the head of the Bioengineering & Instrumentation Group and co-director of the newly established Ames Aerobiology Laboratory.  Gentry received her Ph.D. in bioengineering from Stanford in 2015 as part of the Ames Graduate Cooperative Program.  She did her thesis work in the pioneering area of synthetic biomaterials, and in addition to continuing this work has developed a laboratory focused on developing model systems and instrumentation for characterizing dynamic environment/microbe interactions.


  • Diana Gentry's research on microbial model systems for disruptive environmental change has been featured in a short film by RAW Science TV.  The piece focuses on the bioengineering and directed evolution applications of the work, which were supported by a Center Innovation Fund award.  The project, one of the ongoing efforts of the Bioengineering & Instrumentation Group, is developing an automated biofluidics system which exposes microbial cultures to stresses and monitors their response in real time.  Other applications of the work include characterizing the effects of climate change on microenvironments and testing potential planetary habitability.
