Hi. I'm Gabriel Filippelli. I'm a Chancellors, Professor of Earth and Environmental Sciences, and the executive director of the Indiana University Environmental Resilience Inste. Much of my work is inspired by environmental impact on ecosystems and on humans. So in that context, I've done a lot of research work on deep climate, so climate change in the past, as it can critically inform our own societies decisions in controlling climate impacts in the future. In fact, that is one area of research that we focus on quite a bit at the Resilience Institute. We published a book last year, in fact, called Climate Change and Resilience in Indiana and Beyond, which gives some examples of how different sectors and communities can proactively respond to climate change and to minimize the negative impacts. Of course, I also work quite a bit on environmental health topics, particularly lead exposure and lead poisoning in urban environments, and much of my lab groups work has adopted this strategy of community engaged research, so research that is informed by and supported by community involvement in what we call sometimes citizen science. So in these programs, people actually take their own environmental samples with some guidance from us, and we analyze them and provide them recommendations, and in response to that, they've actually sparked some pretty substantial policy changes and some mitigation changes even here in the local level in Indianapolis. And we hope to continue doing this work, as there's much still to be done, as we're understanding not only the prevalence of the impact of lead on societal health, but also other environmental factors related to climate change like air quality, flooding, and so forth.
