Professional background

Professor Lockley is a medical oncologist, specialising in the treatment and clinical investigation of ovarian cancer. She completed her PhD at the Barts Cancer Institute in 2008 and subsequently held a NIHR Clinical Lectureship at the University of Cambridge. She was appointed as a consultant in 2009.

Prof. Lockley held Cancer Research UK (CRUK) Clinician Scientist and CRUK Advanced Clinician Scientist Fellowships continually between 2011–2021 and became Professor of Medical Oncology at Queen Mary University of London in 2022.

Research interests

Her clinical practice and research programme both focus on ovarian cancer. High grade serous cancer (HGSC) is the most common subtype of ovarian cancer. This disease is initially very responsive to platinum and taxane chemotherapy but more than 70% patients develop chemotherapy resistance and the disease becomes incurable. PARP inhibitors are increasingly used in the treatment of ovarian cancer but resistance to these drugs is common and optimal duration of therapy is largely unknown. Circumventing drug resistance is therefore a major unmet clinical need. 

Prof. Lockley leads a laboratory group at Barts Cancer Institute, Queen Mary University of London. Her lab aims to improve treatments for women with ovarian cancer, particularly those that are resistant to drug therapy. One such approach is called Adaptive Therapy (AT). AT is a novel treatment paradigm in which drug dose is tailored to the evolution of chemotherapy resistance in individual patients over time. We have successfully translated our research findings investigating AT to the ACTOv clinical trial (Adaptive ChemoTherapy in Ovarian cancer) that will recruit patients from 9 UK sites beginning in 2023.

She also has a special interest in rare gynaecological cancers, particularly ovarian germ cell tumours. She is a member of the NCRI early onset working party and Vice Chair of the Malignant Germ cell tumour International Consortium (MaGIC) where she is co-leading development of the next international trial for poor risk germ cell tumours.
