Research & publications

Her research interests focus on endovascular techniques for the treatment of arterial and venous disease, incorporating new advances in technology. She works closely with the engineering group at the Hamlyn Centre, Imperial College London. Miss Riga has led the translational endovascular robotic research theme at Imperial College, publishing the first pre-clinical evidence for the advantages of robotic technology in complex endovascular tasks such as supra-aortic branch intervention and fenestrated endografting. Her research has won 30 national and international prizes, attracting over £10 million in funding including a UK flagship EPSRC investment to make Imperial the UK's largest translational micro-robotics facility.
