Director of communications Chris Wermann works with nutritionist Jenny Watson at Kellogg's. Chris on Jenny We first met in Kellogg's Manchester offices two-and-a-half years ago, when we were getting to grips with the World Health Organisation's obesity challenge. We both work in the public affairs/regulatory environment and have to report back to the team. Most of our working relationship takes place online but we manage meet in the office occasionally or at meetings elsewhere, and at our regular nutritional conferences. Sometimes we only meet for 10 minutes before a meeting because we agree the agenda and our approach beforehand. If we're at a meeting away from home we try to socialise. Jenny helps me understand the science and explains what the challenges are, how we can deliver results and also how to understand the effects the regulatory challenges have on the business. She's analytical and good at taking in facts. I am better at understanding the political environment. I am a feet-first individual and she has taught me to stand back and think before I speak. She's much more rational and keeps me in check, but she's no shrinking violet. Jenny on Chris We've worked together ever since I started at Kellogg's. We partner each other on every issue that involves nutrition, which means we're pretty much in daily contact. The difficulty is that Chris is based in London and I'm in Manchester. On the rare occasion that he's up in Manchester, I'm usually in London so we're often like ships passing in the night. Chris is a bit of a mentor for me. He's not a nutritionist, so it's useful to get his perspective on issues. He is extremely tenacious - he never gives up on anything. Even when I'm ready to throw in the towel, he wants to keep going. He's always positive and, if I get too wrapped up in the science, he brings me down to earth and reminds we why we're doing it. He's very pragmatic. He also works very hard and will leave his home in Henley to drive to Manchester at 4am so he's in the office before people who just live round the corner. I often tell him he looks tired and he needs to go home to concentrate on life, but he can always see something else he's got to do to save the world.
