 Welcome to this SIB course on the BG resource on gene expression made useful easily the tools and database of BG. We are going to start by introducing ourselves, the trainers and developers of BG. And then we will go through the course and ordering this course, we will try to keep things interactive and active so that you will often be asked to do things, whether it's filling information in the Google Doc for which you have links or answer little quizzes on a formula which is called the WUCLAP, similar to other platforms like this. So first presenting ourselves. So I am Mark Robinson Rashavi, I'm a professor of bioinformatics and ecology and evolution at the University of Lausanne for a long time. I did my PhD on the evolution of rodent genomes doing bioinformatics before the word bioinformatics existed in 97. So I actually if you check have a PhD in biometrics because bioinformatics did not exist. I started, I got the first small grant for a project which I thought would be short and easy to organize expression with ontologies and homology between species in 2003. It proved to be slightly bigger than I first thought. And when I got the position and you expanded this project and the key point which Frederick will tell you about was that Frederick joined my group in 2007 and has been working with me on BG since then. And more generally my research group does bioinformatics resources, especially BG, but also fundamental research on evolution. So I'm interested in evo-devo and how you can use evolution of development to get new hypothesis in molecular evolution of population genomics. And in that context gene duplication natural selection are especially interesting. And I work on different organisms. So I have a big project on ultraplots, a big project on fishes. And as those of you who do bioinformatics know, it's quite easy to change species in bioinformatics. So that's where I am. I see that there's a question in the chat. No, it's just a link to a group. And just a bit more person, more about me. So first you should know one thing about me is that they don't like to speak about me. So there are no personal photos, no kids, no vacations. And second, in the previous side, I said that I also like to, I don't shut up. So I have very strong opinions on open access, equality in science, science outreach and the position of science in society. And I'm quite active on this. So if you look at my Twitter, I tweet a lot. I also used to have a blog. I'm active in my faculty and so on. So just one photo to illustrate this, this was the photo which illustrated a tribute and oped we published with quite a few younger scientists. That was the only old guy in this defending science against pseudo science in the French media, French speaking media. It was published at the same time in Switzerland, France, Belgium and Canada. And this is the photo. They only took the Swiss guys for the photo for the publication in Switzerland. Here is our group a few years ago just to show you the wonderful t-shirts we made, which are t-shirt full of equations of bioinformatics and biology. These three photos show the group at different times. This was the first group photo in 2007 with Frédéric was this was our first meeting during the pandemic. We managed to find a place to meet in the woods outdoors. It was a bit cold, but at least we were together. You could talk science. And this is our most recent group retreat in the top of Los Angeles in the snow this winter. And just this photo has a funny little story. I was co-organizing a conference in Basel and the organizers should all have something green to show them. So they prepare a green tie for me, but they didn't know that they come to the conference only with my t-shirts, my science t-shirts. Like this one is a plus completion budget t-shirt. This one has equations. So I could not wear a tie, but they had scarfs for women. So I took the scarf and they the organizers thought it very fun. And I'm using that I was wearing the scarf for women, which I have no problem with as a proponent of equality. So that's my short presentation. And I'll give the mic to Frédéric and change the side. Yes. Hello. So I work with Mark and Frédéric Bastion. So as Mark said, I arrived in Lausanne in 2007 to do my PhD, which was about analysis of gene expression patterns in animals. So it's been a while that I work on gene expression. And I looked like on this picture at the time. So yeah, time passes. And at the time we started BG with only five species and only EST data. But at the end of my PhD, the Swiss Institute of Bioinformatics decided to found the BG database. And nowadays we are a team of eight people working at developing BG and the related bioconductor packages. And now officially I'm the associate director of the group Evolutionary Bioinformatics at the Swiss Institute of Bioinformatics. And you can switch slide, Mark, please. And yes, just to show you, it has been a fun journey with lots of conferences in great places such as Shanghai on the bottom right and lots of hiking session or group writing sessions at the top left. And a lot of conferences with Mark, actually, that you see at the bottom as well during a great conference dinner. So yeah, I mean, over the years, as most of you, I guess, lots of really cool events.
