The Multi-Motive Model of Behaviour Change & the Multi-Motive Design Tool Problem Designers working on behaviour-change problems do not have effective ways of meeting the needs of different types of users or addressing users whose preferences change over time. Approach I devised a framework that segments users into groups based on their motives for performing behaviours. The framework was validated through structural equation modelling methods. I then created a design tool based on the framework and tested it with professional designers who found it easy to learn and applicable to many types of behaviour-change problems. The tool demonstrably increased the number and variety of their solution concepts. This research was nominated for the best paper award at the 2015 ASME Design & Technical Conferences. HOW DO WE ENABLE WORKING MOTHERS TO BREASTFEED? A Robust Breastmilk Pasteurization Device for Use in the Bangladeshi Garment Industry Problem Long work hours and a lack of childcare support in Bangladesh’s garment industry makes it impossible for its 3.2 million female workers to breastfeed, leading to child malnutrition. Approach I was the technical lead in the design of a pasteurization device that increases the shelflife of breastmilk in a seing where refrigeration is unavailable. This patented device enables breastfeeding women to express milk during work hours, pasteurize it, and take it home where a caregiver can feed their child. The device is low cost, sanitary, robust and easy to use. This project won a $100,000 grant from Grand Challenges Canada and was a collaboration with ICDDR,B (an international NGO), the device is currently being tested across Bangladesh. HOW DO WE ENCOURAGE CONSERVATION BEHAVIOURS RELIABLY? The Principle of Discretization Problem Reducing people’s ecological footprint is an effective way to mitigate climate change, but it is very difficult to convince people to reduce their resource consumption Approach I studied lead-user populations that have low ecological footprints. Aſter fieldwork among the Old Order Mennonites of Ontario, I posited the principle of discretization: people were likely to conserve when the resource was available in discrete units (e.g. logs of wood, buckets of water). I experimentally validated the principle and designed a water-saving showerhead based on it. My study is now a part of the design curriculum of multiple universities and was nominated for the best paper award at the 2011 ASME Design & Technical Conferences. HOW DO WE IMPROVE NUTRITION IN SOUTH ASIAN SLUMS? A Scalable Aquaponic System for South Asia Problem South Asia’s peri-urban slums are home to over 270 million people. The residents of these slums experience extreme poverty and malnourishment. Approach I worked on a team with public health and global affairs experts to design an aquaponics system that would provide families with regular sources of protein and micronutrients (100 bunches of leafy greens every 5-6 weeks, 2.5kg of fish every 10 weeks). The system is scalable and robust to electricity outages. I developed the technical specifications for this system and produced prototypes. This project was a collaboration with WaterFarmers Aquaponics consultants in Canada and the Bangladesh Agricultural Research Institute.

HOW DO WE CHANGE USER BEHAVIOUR WHEN USERS VARY SO MUCH?The Multi-Motive Model of Behaviour Change & the Multi-Motive Design Tool
ProblemDesigners working on behaviour-change problems do not have e�ective ways of meeting the needs of di�erent types of users or addressing users whose preferences change over time.ApproachI devised a framework that segments users into groups based on their motives for performing behaviours. The framework was validated through structural equation modelling methods. I then created a design tool based on the framework and tested it with professional designers who found it easy to learn and applicable to many types of behaviour-change problems. The tool demonstrably increased the number and variety of their solution concepts. This research was nominated for the best paper award at the 2015 ASME Design & Technical Conferences.
