Irene Miguel-Aliaga

Miguel-Aliaga is from Spain and grew up in Barcelona.[4] She completed her Doctor of Philosophy degree at the University of Oxford,[1] supervised by Kay Davies on invertebrate models of human diseases.[3][4]

After her PhD, she moved to the United States for postdoctoral research, joining the laboratory of Stefan Thor at Harvard University. Miguel-Aliaga then moved to Linköping University, where she characterised the neurons of Drosophila.[3] She was awarded a Marie Skłodowska-Curie Actions fellowship and joined Alex Gould at the National Institute for Medical Research, where she studied the specification of gut-innervating insulin-producing neurons.[3] In 2008, Miguel-Aliaga started her independent research career at the University of Cambridge. She was named a Wellcome Trust Career Development Fellow, and eventually moved to Imperial College London.[3] At Imperial, Miguel-Aliaga serves as Professor of Genetics and Physiology.[3]

Miguel-Aliaga's research investigates the plasticity of human organs, and in particular, how fully developed adult organs are impacted by environmental changes.[6] To understand these processes, Miguel-Aliaga makes use of the gastrointestinal tract,[7] as it allows for the study of how an organ senses signals from its internal and external environments.[6] To better understand the functional significance of various organs, Miguel-Aliaga compared the intestinal epithelium of males and females. She identified that different biological sexes demonstrate different brain-gut communications, particularly during production and tumour formation.[8] As part of this work, her group identified the communication pathways that exist between the gastrointestinal tract and other organs. She has continued to use the model organism Drosophila, as it shares over 60% of its genes with humans.[8]
