The Garcia group research interest is to understand the molecular mechanisms that maintain genome integrity in stem cells and how lose of genome integrity leads to development of cancer during ageing. Her research focus on both embryonic stem cells ESC/iPSC and adult stem cells, in particular haempoietic stem cells (and how genome instability leads to blood disorders during ageing).

Qualifications

Principal Investigator in Stem cells and genome stability:

  • PhD (1997) Medical School, Universidad Autónoma of Madrid
  • BSc Biology (1994) School of Biology, Universidad Autónoma of Madrid

Biography

Paloma Garcia studied Biology at the Universidad Autonoma of Madrid, Spain and joined the lab of Professor Carmela Cales at the School of Medicine (Universidad Autonoma, Madrid) for a PhD project studying the molecular mechanisms leading to the establishment of endoreplicative cycles in megakaryocytes (1994-1997). During this period Paloma was awrded an EMBO short term fellowship to perform some of these studies at the Weatherall Institute of Molecular Medicine (WIMM), Oxford, under the supervision of Professor Jon Frampton. 

Following her PhD work, Paloma was awarded a Marie Curie fellowship to join Professor Frampton lab in WIMM, Oxford, where she established a conditional gene deletion approach to investigate MybL2 function and started working on stem/progenitor cell properties and the development of blood disorders. 

In 2002 she moved to University of Birmingham as a senior postdoctoral researcher funded through the Leukaemia and Lymphoma Research (LLR). She was able to demonstrate that correct levels of MybL2 are necessary to maintain genome stability in human haemopoietic cells, and that low levels result in DNA fragmentation and chromosome rearrangements. 

García’s independent research group was established in 2009, once she was awarded a Researcher Fellow position at the University of Birmingham through the Science City Research Alliance scheme (SCRA). Using her mouse model, she demonstrated the importance of MybL2 in the development of blood disorders during ageing. She also led the investigation that revealed a role for MybL2 in the elongation rate of replication forks in ESC.

She now holds a Senior Researcher position at the University of Birmingham

Teaching

Undergraduate

Masters

  • MSc Mol Mech Immunol

Postgraduate supervision

Dr Paloma Garcia is interested in supervising doctoral research students in the following areas:

* molecular mechanisms controlling genome stability in embryonic stem cells and induced pluripotent stem cells

* molecular mechanisms of somatic reprogramming to induced pluripotent stem cells

* molecular mechanisms underlying blood disorders during ageing.

Self-funded PhD students are welcome to apply.

Research

  • Mechanisms regulating proliferation and genomic stability in embryonic stem cells and somatic cells, with a special focus into the role of the transcription factor MybL2 (B-Myb) at the interplay between DNA replication and DNA repair.

• Investigation of the molecular basis behind the deletion of chromosome 20q (del20q), and in particular the role of MybL2 haploinsuficiency in the development of haematological diseases.

• Gene expression mechanisms regulating haemopoietic stem cell self-renewal and differentiation; in particular, studies on the transcription factor c-Myb are a major, on-going research project because of its central role in coordinating signaling and gene expression events.
