Biography

I have dedicated my career to understanding how and why we age and to the development of therapies to prevent, delay or reverse ageing and age-related diseases. In 2006, I obtained my PhD in Biology from Complutense University of Madrid, after receiving additional training in Poland and the United States. After my PhD, I moved to Finland as a postdoc supported by a long-term EMBO fellowship.

In 2010, I was awarded a Starting Grant from the ERC to establish my laboratory and was nominated as a Research Academy Fellow by the Finnish Academy. In 2014, I was recruited by Newcastle University, where I was promoted to full professor in 2019. In 2018, I received a Senior Research Fellowship from Wellcome.

In 2020, I joined the University of Glasgow as a Lord Kelvin/Adam Smith Professor. My laboratory is funded by the BBSRC, Wellcome and the University of Glasgow, and our work has been published in the prestigious journals in the field such as Cell Metabolism, PNAS, Nature Communications or Redox Biology.

Our laboratory is interested in understanding how information flows between the mitochondria and the rest of the cell, the way mitochondrial signals contribute to cellular homeostasis and why damaged mitochondria accumulate during ageing. To achieve our ultimate goal of helping people live healthier for longer, we have established strategic collaborations with other national and international research groups. If you are interested in collaborating or interacting with us, please don’t hesitate to contact us.

Research interests

How and why we age are two of the most intriguing biological questions which remain unanswered. Ageing is the major issue public health services around the globe are facing. Understanding ageing requires identification of the biological processes that affect it. One of the hallmarks of ageing is the accumulation of defective mitochondria that produce more mitochondrial Reactive Oxygen Species (mtROS). ROS are both a toxic by-product of metabolism and essential cellular messengers. Our laboratory and others have shown that mtROS are essential regulators of lifespan and that by boosting mtROS production, it is possible to improve animal health and allow them to live longer.

We do not know mechanistically how mtROS regulate longevity, and therefore, cannot currently use them as a therapeutic tool to extend healthspan. Although mtROS were described decades ago, we are only just starting to understand the role they play in cellular signalling and how they control essential cellular processes such as differentiation, proliferation and cell death. Our laboratory aims to fill these gaps and provide new and relevant knowledge which would allow the use mtROS as a therapeutical tool to prevent, delay or reverse ageing and age-related diseases. We work on four different areas in collaboration with national and international partners:

How is information exchanged between the mitochondrion and the rest of the cell? Why is this interrupted during ageing?
Where and how are mtROS produced within mitochondria? How does redox signalling contribute to cellular homeostasis?
What are the genetic and epigenetic mechanisms that underlie the accumulation of damaged mitochondria during ageing?
Development of technologies allowing the manipulation of mitochondrial function to extend healthspan and prevent age-related diseases.
