Biography
My area of expertise is Human-Computer Interaction / User Experience, and Psychology of Voice (previously I worked as a full-stack software engineer, specialising in front-end development). I have seven years of industry experience in leading projects and multidisciplinary teams in the UK and abroad (ranging from financial and investment products, to telematics and car insurance, to AI social listening tools, etc). Past clients and employers include Aviva, Panasonic Avionics, Disney and PepsiCo among others. 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 (so, cakes are always welcome!) ------------------------------------------------ https://orcid.org/0000-0002-9443-4226 ------------------------------------------------ JOURNAL PUBLICATIONS: Maltezou-Papastylianou, C., Russo, R., Wallace, D., Harmsworth, C., & Paulmann, S.
