I am currently working as a Research Fellow at the Australian National University (ANU), where my research is partially funded by the University of Edinburgh for my contribution to the Scottish Historic Population Platform (SHiPP) project [1] as part of my employment. I obtained my PhD degree from the ANU in 2022, where the focus of my doctoral research work was on proposing Effective Record Linkage Techniques for Complex Population Data [2]Record linkage is the task of identifying records in a dataset which relate to the same entity. It is an important step in cleaning datasets (for duplicate removal) and extensively used for tasks such as population reconstruction. In the absence of unique identifiers per records, a record linkage method must be used to identify whether two records relate to the same entity. This task is particularly complicated where population datasets (data about people) are concerned, due to the many mistakes introduced to them at the time of data entry and transcription, errors and variations in names, and the imbalance in name distributions (many people sharing common names and few very uncommon names), etc. My focus is on developing effective record linkage techniques using which high quality population record linkage can be achieved. For a comprehensive list of my publications, please see my Google Scholar profile [3].
