I’m Adair Oesterle, the founder of Microtul.I've worked in the biotechnology industry for 25+ years as an application engineer. My journey in research began at the Marine Biological Labs located in Woods Hole, MA.My expertise includes technical support, scientific writing, manufacturing and beta testing biomedical research instruments, conducting transgenic research, and the production of custom micropipettes. I am a specialist in microinjection applications and am the author of the Pipette Cookbook (2005 – 2025 editions).My experience has been further enriched through contracting opportunities with the International Atomic Energy Agency, Google/Verily, Lawrence Livermore National Labs, the Massachusetts Institute of Technology, UCSF, and Smithsonian/USDA alliance.I am eager to collaborate with you to assess your research requirements and assist in developing the ideal laboratory configuration and microtools.
