 So good morning, everyone. Thank you for joining this SAB course on the BG database, making gene expression useful easily. I'm Marc Robinson-Rachavi and with Frédéric Bastion, we're going to be giving this course. And so we start with the introduction of us, of the trainers, so that you know a bit who we are and where we come from and how we're making this database. We have here links to our social media presence on Mastodon and Twitter. And is the slides changing? Yes. So I'm Marc Robinson-Rachavi. I am originally French. I obtained a PhD in Lyon in France on the evolution of rodent genomes in the previous millennium. During that PhD, I mixed experimental biology and bioinformatics. And after I defended my PhD, I never did experimental biology again. I preferred bioinformatics. And I've been a professor of bioinformatics in the Department of Ecology and Evolution of Lausanne, Switzerland since 2005, where I had a group which on the one hand studies evolution in biology, on the other hand develops bioinformatics tools, including, I mean, most importantly, BG. BG actually started on the first small site project on trying to have homologous gene expression in 2003, while I was still in Lyon. And I restarted the program when I joined Lausanne. And then I hired Frédéric. And that's when really the project really became functional. So my research group is focused on the relationship to genomics and evo-divo, as well as related topics such as gene duplication, natural selection. And also since I'm introducing myself, something about me is that I am very passionate about many issues about science and society. So I'm an activist of open access. I'm an activist of equity, diversity and integration in science. I like a lot to communicate science, although with blogs have been going down. And I'm not the kind of guy to make a YouTube channel. I do it less than before. But now you can find me on Mastodon speaking about all kinds of things. Mastodon is an open source and decentralized alternative to Twitter, basically. And these are just some photos illustrating my career these last years. So this is the group as it was in Lausanne in 2006 or 2007. This is the one meeting we managed to have outside in the woods during campus closure at the worst of the COVID closures. This is the group a few years ago. We have a t-shirt with biology equations. This is after I had my integral lesson as a full professor of giving me a nice envelope from the group. And this is a funny story that I was in a conference, organizing a conference, and they wanted me to wear a green tie to identify me as organizer. But I did not wear a shirt. I was wearing a t-shirt. I hadn't brought any shirts. I never wear ties. So I said I can't wear a tie. They said, well, we also have a scarf, a green scarf for women who organize the conference. I said, cool, give me the scarf. So they were very, they really like this, the organizers that I was wearing the women's scarf and they took photos of it. And this is the group in our latest group meeting in December. So you see it's a quite big group with a lot of people who work on different subjects. And now I'll give the floor to Frédéric. Hello. So I'm Frédéric Bastion. I also studied in France. I'm French. So I have a background in ecology and evolution. And I joined the labs of Mark in 2007. And my work was to study the evolution of gene expression after duplication. And for these, we wanted to build a database allowing to compare gene expression between as many species as possible. And at the time, that was only in five species, the five mother species. And then at the end of my PhD, the Swiss Institute of Bioinformatics decided to support BG to found BG. So I stayed in Lausanne. And now the team has ruled over the years and now we are a team of eight people working at developing this database allowing biologists to get clear information about gene expression where genes are expressed to make comparison between species. And now we have 52 species in BG. And so now after a few years now at the SIB, I'm an associate director in the evolutionary bioinformatics group of Mark. And I lead the development of the BG database. I lead the team developing BG. So I also have a few photos just to show you what we like to do in the work setting. So on the right, you get a lot of photos at social events. And I would say it's because it's kind of representative of how I conduct collaborations. I mean, I set a lot of collaborations during those kind of social events actually. Yeah, I like to interact with people in kind of informal settings like that. And on the left, on the top left, you have a photo where the whole group was working at writing a paper. And I like this kind of collaborative work environment. Developing a database is definitely something that it's not a project that you conduct alone. It has to be a group work. And I very much like this. And so yeah, Mark and I, we go back a long way now. So you see also a photo that I take of Mark taking a photo of me, you know, at a conference of three years back. And yeah, that's it, I guess, for introducing ourselves. All right. Sorry, thank you. And so for those who joined in the last minutes, welcome also. And on the document of the course, you have a link to a Google doc to introduce yourselves. So in a few words, you know, whether you consider yourself a bioinformatician, computation biologist, a microbiologist, evodivo zoologist or whatever.
