I grew up in Madrid, Spain, and carried out my first degree in Biological Sciences at the Universidad Complutense in Madrid, graduating in 1986. I obtained my PhD (DPhil) from the University of Oxford (Madgalen College) in 1990, on Drosophila developmental genetics and supervised by Prof. Phil W. Ingham. I subsequently (1990-1992) obtained a post-doctoral fellowship from the Spanish Ministry of Science and Education to do a post-doctoral period with Prof Antonio García-Bellido, at the Universidad Autónoma de Madrid, working on the control of growth and form in Drosophila development.
I returned to UK with a Marie Curie Human Capital and Mobility Fellowship to do a second post-doc with Prof Andrea H. Brand at the Wellcome/CR-UK Institute, University of Cambridge (1993-1997). After this, I was awarded a Wellcome Trust Research Career Development Fellowship to establish my independent research group at the Department of Genetics, University of Cambridge (1997-2002). Here, I established my line of research into neuron-glia interactions during nervous system development. In 2001 I received an EMBO Young Investigator Award for my achievements as a young group leader.
In 2002, I moved to the School of Biosciences, University of Birmingham, appointed Senior Lecturer, and where I consolidated my research into nervous system development using Drosophila.

Nervous system development: structural and developmental plasticity
Our lab aims to understand how the nervous system is formed, and how it works. Structure and function come together in the course of development, and influence each other throughout life, endowing the nervous system with plasticity. As the animal grows and nervous system volume and cell number increase, the two cell types in the nervous system - neurons and glial cells - make adjustments that modify migration patterns, axonal trajectories, cell division and cell survival. These plastic adjustments result in the robust, reproducible formation of the nervous system across individuals, and over evolutionary time. Conversely, these cell interactions fail in diseases of the nervous system and brain (e.g. neurodegenerative diseases, psychiatric disorders and brain tumours) and upon injury (e.g. upon spinal cord injury and stroke).
We use the fruit-fly Drosophila because it is a very powerful model organism to address questions swiftly, in vivo and with single cell resolution. Our approach combines genetics, molecular biology, cell culture, computational analysis and in vivo confocal microscopy in fixed specimens and in time-lapse.
We have focused on: how neuron-glia interactions influence axonal patterns, glial migration and cell number during axon guidance; the control of cell number by gliatrophic factors and neurotrophic factors during connectivity; and the influence of neuron-glia interactions in glial proliferation. We are currently working on neurotrophic factors, regeneration and image processing to address neuroscience questions, always within the context of neuron-glia interactions and developmental and structural plasticity.
Ultimately, our findings help understand nervous system structural and developmental plasticity; brain evolution and the mechanisms underlying different brain types and behaviours; and how to repair the diseased or damaged nervous system with relevance also for humans.
