 Constantina Maltezou



I'm a User Experience and Psychology researcher with seven years of industry experience in leading projects and multidisciplinary teams (ranging from financial and investment products, to telematics and car insurance, to AI social listening tools, etc). I'm also a certified Design Sprint organiser and facilitator (i.e. running participatory design workshops). I come from a multidisciplinary background, which stems from computer science, human-computer interaction, psychology and ethnographic methods. I'm currently working on my PhD research, which combines psychology with human-machine interaction to determine factors derived from vocal cues that influence the perceived trustworthiness of a speaker (whether human or AI), how this impacts acceptance and use of voice technologies by older adults and ethnic minorities, and how this in turn can impact their social inclusion, motivation and empowerment. When I'm not working I love social boardgame nights, playing squash and I'm a big foodie like my husband (so, cakes are always welcome!)
