Hi, my name is Cesar de la Fuente, and I'm a Presidential Associate Professor at University of Pennsylvania. Today I'd like to tell you about how we've been using, for a number of years now, artificial intelligence approaches for antibiotic discovery.

Antibiotic resistance is a huge global health problem. It affects every corner of the world. I could make the case that it is the most underinvested area that affects the most people in the world. We can see here, currently antimicrobial-resistant infections—these are bacterial infections, they are associated with millions of deaths every single year. The current projection is that by 2050, that number is going to go up to about 10 million deaths per year around the world. As we can see here that this is going to surpass every other major cause of death in our society, including cancer, diabetes, and many other causes of death. If we do a quick calculation, those 10 million deaths per year actually correspond to about one death every three seconds. Really, this is a huge global health problem that affects really all of us, and we can refer to it as a silent pandemic where we need to do something about it. Throughout my whole career, I've been really passionate about this huge problem, and I have been trying to think of out-of-the-box methods or approaches to try to counter AMR.

In my lab, I'm really fortunate to be working at this intersection between machines and biology. We believe that by using the power of machines, we can accelerate discoveries in biology and medicine, including antibiotic discovery. I'm really fortunate to be able to work with people that come to my lab from all walks of life and from many different parts of the world. Many of them have different ways of thinking about problems and they have different expertise. To give you an example, right now in my lab we have people with computer science backgrounds, with chemistry backgrounds, people that are microbiologists, engineers, and so on. We all work together to try to tackle a lot of the things that I'm going to describe today. I'm going to talk about all of this chronologically and how I got into this field and so on.
