Appointment as W3 professor and two first PhDs started at JLU Gießen

For the third time in my life, I had to built up a full HPTLC laboratory, as again nothing was there. So far, I never had the situation to join and start. Always, first I had to built up and establish everything.

Substitute W3 professorship at JLU Gießen

The professor at the time resigned earlier. One round of applications had already fallen through and the second call was in progress. The Privatdozent in the group fighted with the faculty and was not cooperative at all, as he expected still to get the professorship. Having a full position, he took his holidays when the courses started, so the professor lectures and the Privatdozent lectures (not even one slide obtained from him) had to be held by me. Before I started, he transfered one PhD student to the Food Chemistry department in Hamburg and the second was his girl-friend. The lab technician refused to have contact with solvents and solved a task in the way so that you have even more problems thereafter (not even a simple buffer preparation was possible). The result was: No expertise but a spion left for my start. So the first practical courses were almost impossible to be held, but we did. The loyality of the secretary was one light in the darkness, which touched me. The faculty was in a very bad monetary position when I started and there was hardly any support possible. My husband commented on my desire to take on the substitute professorship with no support, while my children were fully supportive. This experience gave my vita another feministic nuance. Would you have succeeded under these circumstances (110-h weeks from 2004 to 2018)?

Start as post-doc

After several moves due to my husband´s career, arriving this time in Stuttgart. After some trials, I got the chance to work as post-doc first on a 0.5 (no one believed in a mother with 3 toddlers, I was told later), then after 6 months, on a 1.0 post-doc position at the University of Hohenheim. There was only TLC in the food chemistry education and no HPTLC instrumentation. I successfully obtained funding for one complete HPTLC system to start with the research I was expert in. When I myself installed the ten devices over a week in the before emptied lab, two other post-docs passing the door stopped several times and stunned ("never seen so much equipment for doing just TLC"). For education, I convinced the open-minded director to buy used systems of the previous generation to enable at least automation, which I found is a prerequisite not to discriminate this technique. Step by step, another instrument was bought from the very rare universitary budget over the years. Finally when I left after 7 years, there have been two full HPTLC systems of the newest generation... and the feeling that there was laid a seed that now grows without me.

Scientific Consultant

Births of 3 children and working from home for 5 years, on scientific issues or as back office for my successor who got everything handed on a silver platter. It is still the same circumstance: the decision to become a mother destroys your career. Home-office was not accepted as part of a career at that time. I became a male-supporting female worker bee. First this period and experience gave my vita a feministic nuance, as it was no longer fair at all.

Head of Laboratory

Working as the Head of the Laboratory for 3 years in Switzerland. I had to start from the scratch, as there was no task transfer from my precessor (he made the DOS command Format C: on the computer). He was, after contract cancellation, immediately ill and then on vaccation. Arriving there, one of my two laboratory technicians refused to give me a hand shake, and I was wondering why. She was the life partner of my precessor and had quitted. However, we still had 2 months of working together. At the end, she came to my office and said that she strongly regrets that she quitted. The lab had had no head for 4 months and I had to start from the scratch and to manage a large overhanging workload (100-h weeks). I newly designed teaching courses writing a thousand slides, solved over 60 industrial confidential analytical problems and performed hundreds of instrument tests. The laboratory quality management system was also established. Result was a testimonial with the highest rating and a very very great offer not to quit (but I was pregnant and had to leave the country, as my husband did not get a job in CH). Working until the 9th month of pregnancy and then remote, the lab was in the best condition and well-structured when my successor started. He got all concepts, slides, and more....  What a difference in the start!

PhD at Saarland University, Saarbrücken

A cummulative PhD thesis was not possible and no issue at that time. My doctor father, who was the pope in HPTLC at that time, Prof. Dr. H. Jork suddenly died in 1994, and thankfully, I could finish my thesis (writing process) under the supervision of Prof. Dr. H. Engelhardt, his strongest oponent at the same university, in 1995. Already working 60 h per week as Head of the Laboratory, I had the defence of my PhD work in Saarbrücken  (and my wedding with over 100 guests a week later). Growing up in a small enterprise, it was normal to live for the work you love.
