Lígia is the founding Chief Executive of the Centre for Homelessness Impact, a member of the What Works Network. She set up the Centre in 2018 and led the feasibility study which preceded its creation while at Crisis UK.

Lígia is bringing ‘what works’ methodology to homelessness: the use of reliable evidence and reason to improve outcomes with existing resources. In 2019 Lígia was conferred the Award of Fellow of the Academy of Social Sciences (FAcSS) for her contribution to social science. In 2016 she was awarded a Clore Social Fellowship on Housing and Homelessness, funded by the Oak Foundation.

Lígia was previously at Crisis UK, where over a period of nine years she led the organisation's evidence and data programme - growing its scale and impact so that it's now one of the largest and most influential in the UK and internationally. She joined the charity in March 2008 following stints at the Young Foundation and the Refugee Council. Lígia was awarded a PhD from the Government Department of the London School of Economics in 2007. She has also worked in research roles for Professor David Held, founder of Polity Press, for sociologist Professor Helmut Anheier, who founded and directed the LSE’s Centre for Civil Society, and for the International Labour Organisation where she covered issues including human trafficking, child labour and women’s rights.
