Protecting the Environment
She has dedicated herself to studying human influences on the environment. Anne Tilghman Hall researches the effect of crop protection agents on the environment.
As a student, I decided to become a whale researcher. I’ve always loved nature and am fascinated by the way that living creatures adapt to their environment. So when studying for my bachelor’s degree in biology, I investigated the populations of humpback whales off the West Coast of Greenland and in the Caribbean. I also wanted to assess the influence of humans on their feeding behavior. At the same time, I worked part-time for Greenpeace one summer. We both wanted to protect whales. But Greenpeace’s attitude towards threats was too narrowly focused for me. I wanted to look at things from different perspectives
From 2015-2017 I was the team lead of Bayer’s Nontarget Plant Experts in Monheim Germany. We investigated the potential side effects and conducted risk assessments of Bayer products plants that grow neat the treated crops. From 2017-019 I became the Director of Bayer’s Environmental Toxicology and Risk Assessment Team in the United States; this team looks at the broader picture assessing potential effects on aquatic and terrestrial plants and animals. I am now the Head of Environmental Safety for North America leading a team of outstanding scientist that ensure the environmental safety of BCS products and support sustainable agriculture and pest control options. If I discover that a product might have the potential for side effects on the environment, the interesting part of the work begins. I look to understand the possible interactions and if needed develop solutions that will make the product even safer without changing its targeted effect. I love scientific challenges!
A ‘Go With The Flow’ Kind of Woman
When I was an expat, I had a lot of fun and visited various places in Europe. However, if I could choose where to live, I’d choose the US because of my family. They are very important to me, but I came to Germany without them. So during my first week in Monheim, I thought, ”What have I done?“ But I quickly came to appreciate the joys of living abroad and discovering differences in culture. It was an adventure I don’t regret. I often went hiking, and now I also enjoy urban hiking in different cities. That’s something I never did in the US. But even though I like hiking, I miss the sea. I’ll always be drawn to the water.
Back in my days as a whale researcher, I learned that some things turn out differently than you expect. For example, while I was working on my master’s degree, the whales I was studying suddenly had to move to different feeding grounds and location, making my project not feasible. So I changed my research focus, and concentrated on the ecotoxicological effects of foreign materials on the environment instead. And that's what I’ve been doing ever since. It led me to Bayer, where I have spent the past 24 years.
