David Humphreys

David Humphreys
Senior Consultant

David wandered into UX when he realised he couldn’t code or graphic design, but he was good with people and loved working with the internet. He has been working for Peak since 2007 and has worked with a range of clients from different industries. He still thinks usability testing is fun. He retains a key interest in user behaviour and how that affects design.

Senior Consultant

David has a wonderful family of five, a lot of video games, board games, comics and books and not as much time as he would like. Playing games with the family has been a good strategy and getting them to realise Monopoly is a bad game is a great achievement. A good Indian curry and a nice beer round out any good day and he can’t wait for the mighty Brisbane Lions to return to their winning ways.

After many years away, Amber returned to her hometown Brisbane, with Belgian born husband and young family in tow. She enjoys the nature and quality of life that Brisbane offers, and can often be seen traipsing after two young children across the various local parks, markets and cafes. Her ‘happy place’ is beaches in Australia, or Belgian beer & chocolate cafes back in her second home of Belgium.

Michael spent his whole life informally studying the ways people tick before realising that in his day job as a designer he can help connect people with positive experiences. As a systems thinker he takes a holistic approach to the business problems presented by considering the entire range of people involved. Michael is representing the voice of the user in his work & this really makes him happy.

Senior Consultant

Spending time with his family and friends, constantly listening to music, being absorbed in nature, creating or appreciating visual art, learning new things, or just spacing out on Philosophy reads all constitute good use of free time in his books.

Miranda started her young family around the same time as starting with Peak. She now has three young children and is devoted to them and her husband. Every week seems to fall in to a busy rhythm of school, work, service and play with very little time for rest. Miranda spends her spare time either in entrepreneurial pursuits, personal development, or in community building activities.
