Sasha’s research uses epidemiological methods, randomised trials and evidence synthesis to answer pressing health service/systems questions, with a focus on population ageing. Sasha was the chief investigator of a NIHR funded multi-site randomised trial of Hospital at Home vs hospital admission that was awarded the BGS Dhole-Eddlestone Memorial prize in 2023 and contributed to the evidence supporting NHS England’s virtual ward programme. Currently her research includes understanding the impact of inequalities that drive the need for social care by an older population, she is a co-investigator on CRUK funded research (led by Toral Gathani) on barriers and facilitators to the early diagnosis of breast cancer in ethnic minority women and a co-lead for the Cochrane Thematic Group: People, Health Systems and Public Health.

After an undergraduate degree in psychology from the University of Vermont, Sasha completed a master's at the Harvard School of Public Health and a DPhil at the University of Oxford.
