Ms Darlena David MA MEd

Research Degree Student


I am a PhD candidate and am supervised by Mark Petticrew evaluating (complex) interventions in agriculture and other policies that impact and affect food systems. My PhD at LSHTM focuses on policy-level determinants of access to healthy food, particularly fruits and vegetables, in Kerala, India. My research background is primarily qualitative. 

I am currently a visiting student at the University of California, Berkeley (US). 

Prior to joining LSHTM I worked at the Hesperian Health Guides (Berkeley, US) and developed books that are used as organizing tools to challenge social causes and stigma of disability and inadequate care. Before that I worked in health communications at Christian Medical Association of India and Voluntary Health Association of India (Delhi, India). I also have experience in curriculum development and leading community health management training. 

I have a graduate degree in education and mass media from Manchester University and undergraduate and graduate degrees in English. I also have a postgraduate diploma in hospital administration from the Christian Medical College and Hospital (Vellore, India). 




I have led seminars on software for qualitative analysis (NVivo). I was also Seminar Leader on Disease Control Programmes in Developing Countries and Principles of Primary Health Care and Health Services.


My research focuses on the impact of policies on access to healthy foods in middle- and low-income countries.  Besides this, I have been involved with qualitative research for the MASALA study at  University of California, San Francisco
