We are behavioural
designers
If behaviour connects us, it can be what protects us.
We humans are a complex bunch. Fickle. Erratic. Contradictory. Emotional. Some call these obstacles. At Common Thread, we call them catalysts. And once they’re understood, a few small, careful nudges can move people to positive change. From disease to inequality to climate change. Universal and interconnected problems need solutions that reflect the social and cultural complexity that we all live in.
What We Do
Research Design
We bring the best of applied behavioural science, design thinking and anthropology to original and secondary research.
Experience Design
Through workshops, trainings, services and solutions, we seek to elevate the moments that matter with and for our clients.
Strategy Design
Practical, evidence based and optimised to consider the entire ecosystem of human behaviour.
Storytelling
Context, not content. We support people to explain and reveal their challenges in their own words, to add a human face to graphs and data points. Stories matter.
Our Approach

We listen to all voices and perspectives
Every perspective deserves to be heard so we seek out all voices that play a role in behaviour change. Policymakers and providers, advocates and obstructers, the refusers and early adopters.

We understand the drivers of behavioural change
Uncovering the insights that prove to be the real levers of change. That’s our focus. When we reveal and leverage the motivators of human behaviour, better health is possible.

We unite global science with local context
Our approach fuses the best of design, behavioural science, marketing, public health and anthropology, while amplifying local voices and promoting community solutions.

We design human-centred solutions
We design with people, not for them. From insights, we design and prototype solutions. We test, modify, and start again until they are solving the problems we set out to tackle together.
Our Story
Behavioural design has come a long way.
Common Thread was born out of frustration. Sherine and Mike met while trying to eliminate Polio from Pakistan and immediately bonded over the need to put people, and their actual needs and context at the centre of public health. Five years, a few outbreaks, the births of four children, and a few dozen countries later, we made the leap. Driven by a desire to do great work, with great people, today Common Thread is an emerging leader in behavioral science for global public health. We count the world’s most important organizations as partners, clients and friends.

We want to know what moves you.

Our Team
SHERINE GUIRGUIS is our Director and lead strategist. Sherine looks for the people behind the data. She’s been creating powerful narratives with data for 20 years, from leading large-scale behaviour change strategies to responding to the Indian Ocean Tsunami, ridding the world of polio, and responding to West Africa’s Ebola outbreak. Working with thousands of local women to eliminate Polio from India in 2011 sparked her passion to help understand and improve gender dynamics in public health. Sherine has held senior behaviour change positions with UNICEF and is widely published in public health and social and behaviour change.
Sherine has a MSc in Public Health from the London School of Hygiene and Tropical Medicine and a MA in International Development and Economics from Johns Hopkins University. She is a guest lecturer at New York University’s (NYU’s) School of Global Public Health and sits on a number of Technical Advisory Groups, including for the Global Polio Eradication Initiative and PATH. Sherine speaks Arabic, and loves good food and beautiful design in all its forms. She is a mom to busy twin toddlers, and hopes to one day reclaim her hobbies, which include horseback riding and diving. Sherine lives in Barbados.
MICHAEL COLEMAN is our Director and lead storyteller. Finding and creating space for community voices gets Mike going. He’s always been connecting people and information, from his senior communications posts with UN agencies in Angola, Pakistan, and Viet Nam, to social development, documentary production and journalism in Honduras, Sri Lanka, Canada and Poland. Years spent working to eradicate polio – and being part of the team that managed the attacks on health workers in Pakistan – taught him to waste no time getting to the root of a problem.
Michael is part of a USAID and Gates initiated Community of Practice called Design for Health. Michael has facilitated Design for Health sessions, and has studied Service Design with Marc Stickdorn, a global leader in the field, Michael has a MA in Political Communications from Goldsmiths at the University of London. He has been a guest lecturer at NYU’s School of Global Public Health and a lead trainer for the US Center for Disease Control’s STOP Polio Programme. He is based in Ireland and speaks intermediate French and Spanish.
Felicity keeps us focused on people. With a background in public health, health systems strengthening, and community engagement, Felicity makes sure we are asking ourselves, communities, and clients the right questions for creative solutions.
Felicity oversees research and accounts at Common Thread, and brings a people-centered approach to both. Before joining Common Thread, Felicity worked for Cambridge Economic Policy Associates, the WHO in Geneva and the Philippines, UNICEF in South Asia (Bangladesh, Nepal and Sri Lanka), and for national and sub-national governments, and donors.
Felicity has lived and worked in South Africa, the Philippines, the UK, Switzerland, Bangladesh, China, Colombia, Ghana, and many more countries. She holds a Postgraduate Degree in Public Health from the University of York and a Bachelor’s Degree in Anthropology and Development Studies from the University of Sussex. Felicity is based in the UK.
In her spare time she is a wanderer – loving mountain climbing or any excuse to escape London’s high rises. She paints and loves her Collie dog back in Yorkshire.
Olivia loves to help others thrive. As the People and Project Manager at Common Thread, Olivia uses her passion for connecting with others and wellbeing to nurture our company culture and make sure everyone has what they need to do great work. Before joining Common Thread, Olivia was the Managing Director for Impact Hub Phnom Penh in Cambodia, working with partners such as UNDP, USAID, and Oxfam to train and empower the next generation of local changemakers and entrepreneurs. Olivia has also consulted on a range of projects ranging from design research to training for organisations around the world such as 17 Triggers, Swiss EP, Youth Business International, and Frontier Labs Asia. In her spare time, you can find her running workshops on wellbeing, making embroidery, and doing karaoke.
Lydia loves asking why. Whether buried in dataset or chatting with a couple about their children’s health, Lydia is constantly trying to understand how context shapes people’s. decisions. An epidemiologist by training and behavioural designer by nature, she has spent most of her career designing and evaluating health programmes in sub-Saharan Africa. After receiving her Master’s in Public Health at the University of Cape Town, Lydia worked with ideas42, designing reproductive health programming in Senegal, studying intimate partner violence prevention strategies in India, and understanding how to build empathy between health providers and their clients in Zambia.
Lydia is also an honorary lecturer at the University of Zambia School of Public Health. Otherwise you can find her outdoors—tending her (slowly) budding vegetable garden, trying not to be thrown off her horses, or deftly avoiding crocodiles on the Zambezi river.
Marc brings people together. He co-creates delightful experiences that respond to real problems. He is constantly amazed by how a deep understanding of people can inspire groups to re-design complex systems. He has a Ph.D. in literary and cultural studies from Duke University. He has published scholarly articles, literary translations, original poems, and he was awarded a Digital Humanities grant from the US National Endowment for the Humanities for his project on creative tele-collaboration in the university classroom. He has worked in the US, France, Puerto Rico, Argentina, and Mexico. He speaks English, French, and Spanish. He has taught at University of Miami, State University of New York, Cornell University, and Cornell Weill School of Medicine. He loves drawing, paper-sculpting, and biking.
Jim makes us look good. He blends experience in a wide cross-section of design – from print and UX & UI visual design to 2D animations, illustration and photography – with an extensive history of working with NGOs and international development and environmental agencies. He has a Diploma of Arts (Graphic Arts) from RMIT University and a Bachelor of Arts (Public Relations) from Deakin University. In his spare time, Jim pretends he’s a folk musician, and wears plaid shirts. He also likes dragging a stupidly heavy camera up mountains, and swimming underwater as often as possible.
Katrina brings our ideas to life. With over 12 years of international experience directing art projects, creating brands, and designing artwork, Katrina is part of Common Thread’s growing design team.
Katrina is a believer in form and function and loves to combine logic and design. She is a big fan of empty spaces and good contrast and brings this style to Common Thread. She has a Master’s degree in Roman-German Philology* from Lomonosov Moscow State University and studied Visual Communications at the British Higher School of Design and Art in Moscow.
In her spare time Katrina loves drawing people, on canvas or digitally, and is working on her own series of illustrations. She loves curling up with a good book of fiction and a glass of wine.
*Philology is the study of language in oral and literary history.
Gael brings clarity. The relationship between people, design and the interconnectivity of the systems that make the world go round give Gael energy. She has worked in design, research and strategy for commercial and social projects but is most driven when people are put at the heart of the solution.
Before joining Common Thread her work was centred on community engagement in urban design; mapping urban ecology, investigating service accessibility and putting local voices in the development process. She is excited to apply design thinking to global public health.
One of her proudest achievements is climbing Kilimanjaro. Originally from Scotland, she currently resides in Edinburgh where she enjoys cycling, reading and trying to grow herbs in her tiny garden.
