Resumen de la plática Los ecosistemas extremos representan modelos naturales ideales para entender los principios de la ecología y evolución microbiana. Se emplearon enfoques meta-ómicos de alta capacidad para investigar los efectos de factores abióticos (ej., temperatura) e interacciones biológicas en la composición, estructura y función de las comunidades microbianas y virales en ambientes termales […]

Resumen de la plática Precision medicine has demonstrated the utility of using -omics technology to improve patient care, most dramatically in the field of oncology. So how do we extend this to the prevention of disease? In this talk, we will discuss how the use of AI, real-time environmental monitoring, and exposomics approaches can extend […]

Resumen de la plática In our bodies we have at least as many bacterial cells as human ones. The human microbiome plays a key role in maintaining our health, and alterations in its composition are linked to multiple health conditions, including those linked to our mental health. In the first part of this talk, I […]

Summary: Since Eric Davidson's work on the organization of regulatory elements in enhancers, syntactic properties of the arrangements - order, distances, orientation - of regulatory sites have been evaluated. There are thus various “enhancer grammars”. In that context I show the difference with the grammatical model of microbial transcriptional regulation. On the other hand, the […]

Resumen de la plática At a big picture level, my group at CMU is focused on studying the adaptive properties of spatial structure, across different biological systems. Spatially-resolved datasets are revolutionizing knowledge across many areas in biology, yet are under-utilized for questions in evolutionary biology. When it comes to understanding the role that population structure […]

Summary: Human microbiomes are remarkably person specific. In the skin microbiome, individuals have similar species, yet each person has a unique consortia of strains. How these unique consortia form and persist remains a fundamental open question. To understand the assembly of these complex communities, the Lieberman Lab reconstructs the recent on-person evolution of strains on […]
