Olena Tigova is a public health specialist with over 10 years of experience in tobacco control as both researcher and project coordinator. Her main areas of interest include prevention of exposure to second-hand tobacco smoke in public and private settings, behaviour change, and implementation science. She is also passionate about research methodology and scientific communication.

She holds a PhD (Cum Laude) in Medicine and Translational Research from the University of Barcelona (Spain, 2026), a Master in Public Health from Stockholm University (Sweden, 2014), and a Master in Management of Healthcare Organizations from Kyiv-Mohyla Academy University (Ukraine, 2012).

Since 2016, Olena has been working at the Tobacco Control Unit — initially as scientific manager of international collaborative research projects and since 2020 as a researcher. Her doctoral research, supervised by Prof. Fernández and Dr. Martínez, characterized the prevalence and determinants of smoking and second-hand tobacco smoke exposure in private homes, and included the adaptation and piloting of an intervention to promote smoke-free homes among Catalan households with children.

Olena has co-authored over 50 publications and participated in six international and four national collaborative research projects. She has prior experience in public health research and epidemiology (School of Public Health and AIDS Alliance, Kyiv), health inequalities (Centre for Health Equity Studies, Stockholm; Center for Research on Health and Economics, Barcelona), and healthcare management (CRHIM, Barcelona).
