Evolutionary dynamics of antibiotic resISTANCE

What drives the evolution of antibiotic resistance? How does resistance spread in bacterial populations? Can we predict the evolution of antibiotic resistance?  We are tackling these and other questions in the Evolutionary Dynamics of Antibiotic Resistance Lab, located at the Ramón y Cajal Institute for Health Research (Ramón y Cajal University Hospital) in Madrid. 

Research

Antibiotic resistant bacterial infections are arguably one of the major threats to human health. Our laboratory seeks to understand the ecological and evolutionary processes that drive the emergence and spread of antibiotic resistant clones. Ultimately, this will allow us to develop new therapeutic approaches to tackle the evolution of antimicrobial resistance. We work on the following three highly inter-related topics (among others).

New strategies to counteract the evolution of antimicrobial resistance.

Resistance to virtually all antibiotics has been reported soon after their introduction to clinical use, suggesting that the apparition of resistance will eventually outpace humankind’s ability to develop new antimicrobial compounds. Therefore, there is an urgent need to develop new intervention strategies to counteract the evolution of antibiotic resistance. In the lab, we take advantage of recent molecular biology advances to develop new approaches to overcome antibiotic resistance in bacterial populations.

What drives the ecological and evolutionary success of high-risk bacterial clones?

One of the main drivers of the antimicrobial resistance crisis is the emergence and global dissemination of epidemiologically successful drug-resistant clones. These high-risk clones have acquired certain adaptive traits that increase their pathogenicity and survival skills, including the acquisition of antibiotic resistance. We take advantage of cutting-edge genetic technologies to understand the ecological and evolutionary bases of high-risk clone epidemiological success. We believe that this mechanistic understanding will feed essential information for predicting (and avoiding) future expansions of antimicrobial resistant high-risk clones and provide a conceptual framework to better manage infections.

The role of mobile genetic elements in bacterial evolution.​

Mobile genetic elements play a crucial role in bacterial ecology and evolution because they mobilize key traits by horizontal gene transfer. However, the evolutionary impact of mobile genetic elements goes above and beyond being mere gene delivery platforms. Recent evidence suggests that mobile genetic elements evolve differently than chromosomes. Using experimental approaches combined with mathematical simulations and bioinformatic analyses, we try to decipher and understand the rules governing mobile genetic element evolution.

My work focuses on understanding how bacteria evolve to resist antibiotics, outpacing human efforts to counter bacterial infections. During my PhD, I studied the genetic responses that bacteria elicit when treated with antibiotics, and specifically how these responses can promote bacterial survival and evolution. During my postdoc, I studied a complementary aspect of bacterial evolution; plasmid-mediated antibiotic resistance. In 2021, I started the Evodynamics lab thanks to a Miguel Servet Fellowship. In my spare time, l like mountain biking and brewing my own beer.

Paula Ramiro Martínez

I graduated in Biology at the Rey Juan Carlos University (Madrid, Spain) and have an MSc in Biotechnology. During my internship in clinical microbiology, I fell in love with this field and, above all, became quite interested in antibiotic resistance. Now, I am delighted to be part of the Evodynamics lab and to work on understanding bacterial evolution and its relation with antibiotic resistance. When I'm not in the lab, I love spending time with friends and family, watching series and movies, and reading.

As a person with a profound curiosity for science, I am thrilled to work at the Evodynamics lab and learn new things daily. I am a hard-working, orderly person who tries to help as much as possible. In addition, I like animals and enjoy taking care of my cockatiels, playing video games or cooking sweets.

Cristina herencias rodríguez

Postdoc motivated by the problems that threaten our society, such as climate change and antimicrobial resistance. During my PhD, I focused on the implementation of sustainable processes for the separation of intracellular bioproducts with a metabolic perspective. In 2022, I obtained a Sara Borrell postdoctoral fellowship to develop new therapeutic approaches to tackle the current world health crisis of antibiotic resistance. I love practicing martial arts and traveling.

I have studied a degree in Biology at the Complutense University of Madrid (UCM) and then I worked in the University of León as a research assistant. I was involved in the molecular characterization of antibiotic-resistant bacteria present in food. During this job I became interested in antibiotic resistance and research. I am currently studying a master’s degree in Microbiology and Parasitology at the UCM. Recently I joined the lab to complete my Master’s Thesis. In my spare time, I love going to concerts and hiking.

I'm a Biologist (UCM), currently studying a MSc in Bioinformatics and Computational Biology. After finishing my Bachelor's Thesis in the lab, I'm glad to continue being part of the Evodynamics group. I'm always down to work in new fields that prove a challenge and satisfy my curiosity, such as understanding the evolution of antibiotic resistance. In my free time, I love sports, spending time in nature, and traveling as much as I can!

João Gama

I am a microbiologist, and for some time my research has been focused on bacteria own parasites: phages and plasmids. I am interested in the ecology and evolution of these mobile genetic elements and their consequences for the spread antibiotic resistance. In my spare time I am either listening to some heavy music or being a nerd!

Álvaro San Martín

I'm a biologist (URJC) with master's degrees in biotechnology (UAM) and bioinformatics (ISCIII). I'm passionate about understanding the mechanisms of microbial infections, which led me to pursue a Ph.D. in bioinformatics. Currently, I am delving into microbial pathogenesis under the direction of Dr. Iñigo Lasa at Navarrabiomed in Pamplona and Jero here at the Evodynamics lab. Outside the lab, I enjoy sports and mountain retreats.
