 My PhD project is about waste management systems. We looked into the decisions that can improve the systems in terms of coasts and in terms of environmental impact, mainly looking into transportation decisions, which has to do with the collection and the disposals of garbage and waste that is produced by citizens. And we use optimization tools to make them more efficient in a way that they can reduce emissions, they can reduce coasts and they can improve the overall quality of the system. Well, waste management systems have a huge impact in the environment. A system that doesn't work means a city that starts filling with garbage. So health issues, anything that can come out of that. So making good decisions has an impact on that. Also, it has an impact on the reduction of emissions if you produce very efficient collection routes, you reduce, of course, the traveling times and with that the emissions. And also, well-functioned systems also can incentivize people to actually use the systems for doing recycling, to be more engaged, to actually use this kind of system. So there are three ways that this can make an impact if we help making better decisions. Right now, one interesting thing is all these tools that are available to make research easier in some way. All of these artificial intelligence chatbots like chatdipty or other tools that really helps. It gives a different velocity on the way we do research and that on one hand give us more time to focus on the important questions that we want to answer because they are great helpers and on the other hand, it's a real important time to do research that has to do with climate change. So that's another motivation for me. I know that this kind of research has an impact at the end of the day in the amount of emissions, in how the waste management systems work and I think that's really important now in the age we're living.
