About Merle Van
Den Akker
I study how people make financial decisions — and how financial systems can be designed to improve them.
I am a behavioural scientist working at the intersection of psychology and finance. My work focuses on how individuals make decisions about spending, investing, and risk — and how institutions can design environments that support better outcomes without undermining autonomy.
I currently serve as a Senior Product Manager at the Commonwealth Bank of Australia, where I apply behavioural science to consumer banking and investing products. My role sits at the interface of research, product design, experimentation, and large-scale implementation.
