Natalie is a British Heart Foundation Assistant Professor in the Birmingham Platelet Group headed by Professor Steve Watson.

Natalie has a strong background in cell biology and microscopy in both mammalian and plant cells. Her current research project is investigating platelet signalling using super resolution microscopy to map the location and clustering of the platelet surface receptors, combined with biochemical studies of signalling pathways.

Qualifications

  • PhD in Plant Cell Biology (2009)
  • BSc (Hons) in Biological Science with Study In Continental Europe (2005)

Biography

Natalie undertook her undergraduate studies at the University of Birmingham obtaining a BSc in ‘Biological Sciences with Study in Continental Europe’. She spent her year abroad at the Université Paul Sabatier, Toulouse, France where she completed modules in genetics, molecular cell biology and plant biotechnology.

Natalie’s PhD was in plant cell biology, investigating the role the cytoskeleton plays in the self-incompatibility response of poppy, under the supervision of Professor Noni Franklin-Tong (FRS) at the University of Birmingham. Natalie’s postdoctoral research has seen her move from plants to mammalian cells where she has studied processes such as cell migration, endocytosis and cell signalling.

Her current position, as a British Heart Foundation funded Research Fellow in the Birmingham Platelet Group, is centred on platelet surface receptors, their signalling and the cytoskeleton. The unifying theme throughout Natalie’s work has been the use of cutting-edge microscopy to study cell biology, which is something she thoroughly enjoys.

In addition to research, Natalie has taken on roles to promote ‘Team Science’ within the department and further afield. She was the UoB Team Science Lead for COMPARE from 2017-2021 which promoted Team Science and collaboration between the Universities of Birmingham and Nottingham. This initiative was recognised as an excellent example of a Team Science training initiative by the Academy of Medical Sciences in their 2019 report ‘From innovation to implementation: team science two years on’. Natalie is currently the Team Science Lead for the BHF Accelerator Award for Birmingham.

Natalie has also recently taken on the role of Post Graduate Research (PGR) Lead for ICVS.

Teaching

Postgraduate supervision

Natalie is the Deputy Coordinator for the TAPAS European Commission Horizon 2020 Marie Sklodowska-Curie Innovative Training Network (ITN) European Joint Doctorate. 

Natalie currently supervises PhD students funded by the EU (TAPAS), COMPARE and the BHF all working on different aspects of platelet activation and signalling.

Dr Poulter currently has openings for self-funded PhD students in the area of:

  • Investigating platelet activation and surface receptor signalling using biochemical techniques and advanced microscopy

If you are interesting in studying any of these subject areas please contact Natalie directly, or email the College Graduate School for any general doctoral research enquiries.

Research

Natalie’s main research interest is how the spatial organisation of receptors on the platelet surface relates to platelet signalling and activation, in single platelets as well as those in the more complex structure of the thrombus. The aim of this research is to understand how platelets become activated and how this process can be modulated to control thrombus formation.

One area of her current work is related to (hem)ITAM receptors, particularly the collagen/fibrin(ogen) receptor GPVI, but this is being extended to non-ITAM receptors such as the GPIb-IX-V complex. This work uses super resolution microscopy (particularly dSTORM) to look quantitatively at receptor clustering under different conditions (e.g. spreading on different ligands or in the presence/absence of secondary mediators or inhibitors), localising other signalling molecules within the platelet, investigating receptor shedding and interrogating the downstream signalling pathways via biochemical approaches. The main goal is to understand how the extent of receptor clustering can influence platelet activation and whether interfering with this clustering presents a novel target for anti-platelet therapies in the future.

Other interests include investigating the effect of rare genetic variants of the GPIb receptor complex on platelet function and also the role of the cytoskeleton and associated proteins in platelet adhesion, spreading and thrombus formation.
