`Publications

`
`A note on publication venues: in my primary area of research in Human Computer Interaction (HCI), the ACM
`Conference on Human Factors in Computing Systems (CHI) is considered one of the best forums for dissemination
`of research results and covers the broad spectrum of research in HCI. The ACM Symposium on User Interface
`Software and Technology (UIST) , the ACM Conference on Computer Supported Cooperative Work (CSCW), and
`the European Conference on Computer Supported Cooperative Work (ECSCW) are also of similar quality, but are
`focused on particular sub-areas of the field. Papers in these conferences are refereed as full papers, and have an
`acceptance rate of around 15-25% each year. The top journals in the HCI field are the ACM Transactions on
`Computer-Human Interaction, the Human Computer Interaction journal, and the International Journal of Human
`Computer Studies. I also do research in the fields of Information Visualization and Information and Communication
`Technologies for Development (ICTD) where the IEEE Visualization Conference, IEEE Information Visualization
`Symposium, and the IEEE/ACM International Conference on Information and Communication Technologies for
`Development are the top publication venues with acceptance rates of around 20-30%.
