Dr Shameem S Ladak

Research Associate (Omics)

School/Department: Department of Cardiovascular Sciences


Address: University of Leicester, Department of Cardiovascular Sciences, Clinical Sciences Wing, Glenfield Hospital, Leicester LE3 9QP


Shameem is a Research Associate in Professor Gavin Murphy’s research group. She worked as a postdoctoral researcher at the cardiovascular department, Johns Hopkins University, USA (2018-2019).Shameem obtained her PhD in Immunology and lung transplantation in 2018 following an MRes in immunobiology in 2013 from Newcastle University


Shameem’s research is focused on the vein graft study. Her work involves studying the role of acute shear stress in vein graft disease under the guidance of Mr Mustafa Zakkar using an in vitro and ex vivo shear stress model. The main focus of her study is to identify the immediate changes in different cell layers of veins and interactions between them when they are implanted in a new haemodynamic environment with an aim to offer personalised preventive interventions for patients undergoing coronary bypass graft surgery. In addition to this, Shameem consents patients and records data in CRF.

Shameem is also actively involved in the other ongoing clinical trials including VAL-CARD and Ob-CARD trial and is responsible for processing bloods and samples as per the protocol.
