Stephanie Poernbacher studied technical chemistry in Nuremberg and graduated with a degree in engineering. Since November 2003, she has been working in the materials testing laboratory with a focus on oil analytics at Siemens Energy. Stephanie is frequently invited to give lectures on the subject of oil analysis, for example in Hamburg, Berlin or Ludwigsburg. Since 2007, she has also been a lecturer at the Technical Academy in Wuppertal, where she also mainly focuses on gas-in-oil analysis. The focus of her daily work is also the assessment and evaluation of in-house and third-party analyses as well as R&D. Stephanie has had a pronounced interest in this peripheral area of chemistry since her studies, especially in connection with the production of large electrical devices. Therefore, she has found the ideal combination of her areas of expertise at Siemens Energy. She is an absolute expert in today's TechTalk topic and looks forward to your participation and questions.
