Siân Lax’s current role is within the Cancer Research UK Clinical Trials Unit (CRCTU) where she acts as the first point of contact for clinical investigators wishing to work with the CRCTU.


  • PhD in Biochemistry, 2004
  • BSc (Hons) in Molecular and Cellular Biochemistry, 2001


As the Clinical Trial Facilitator, Siân, manages the CRCTU New Business process and provides assistance in obtaining research grants and contributes to writing clinical trial essential documents, publications and reports.

Before working at the CRCTU, Siân was a post-doctoral research fellow working in Professor Steve Watson’s Platelet Group, understanding the role of the platelet receptor CLEC-2 in regulating the severity of acute lung injury using in vivo models of lung inflammation and injury. Her previous post-doctoral work involved elucidating the in vivo role of hormones in lung injury and the role of mesenchymal stromal cells in lymphoid tissues following infection. Siân obtained her Ph.D. from University of Birmingham in 2004 researching the function of Rho-kinase II in regulated keratinocyte differentiation.
