Melanie Soderstrom is Professor and Associate Head of the Department of Psychology. Her research focuses on the development of language in infants, employing both experimental methods in the laboratory (testing infants' behavioural responses to speech sounds) and observational methods by recording and analyzing infants everyday language experiences. She has been active in the Open and Collaborative Science movement in infancy research, serving on the Board of ManyBabies and leadership in several ManyBabies projects, including as co-lead of the first ManyBabies project, examining infants' preference for infant-directed speech. She also led the ACLEW project, which developed new tools and resources for the study of infants' everyday experiences across cultures and languages. Current projects with her students examine the nature of infant-directed speech in Iranian families and the impact of maternal mental health on maternal speech.
