Rafael Peña Miller
Rafael Peña Miller was born in Mexico City where he obtained a degree in Mathematics from UNAM. He obtained a PhD in Mathematics from Imperial College London, funded by a CONACYT-MEXICO scholarship. One of the publications that emanated from his doctoral research was chosen as the winner of the Lee Segel Prize, a biannual prize awarded by the Society for Mathematical Biology to the best article published in the area of ??mathematical biology. Later, he was a posdoctoral researcher at Biosciences, University of Exeter and in Zoology, University of Oxford, where he participated in several projects in the interface between mathematical modeling and experimental microbiology. He has been invited to do research stays in Switzerland, Spain and Germany. In 2015 he was awarded a Newton Advanced Fellowship by the Royal Society of the United Kingdom.
He is currently an Assistant Professor at the Systems and Synthetic Biology Laboratory of the Center for Genomic Sciences, UNAM, studying the genetic and metabolic mechanisms that enable bacterial communities to implement collective strategies to survive – and thrive – in hostile and rapidly-changing environments.
Specific projects in the Peña-Miller Lab can be grouped into four general areas: 1) using mathematical modelling and experimental evolution to study how environments with complex spatio-temporal structure modulate antibiotic-resistance fitness landscapes. 2) using single-cell microfluidics and image analysis to studying gene regulatory mechanisms that produce phenotypic heterogeneity in a population of genetically-identical cells. 3) modelling the interaction between mobile genetic elements, their bacterial hosts, and the environment. 4) studying how multispecies microbial communities are assembled, with the aim of rationally designing (and controlling) stable and robust synthetic microbial consortia.
