New investigators

We are an international group of students and post-docs using the LENA System or other daylong (audio, video) recordings in their research. On our our monthly conference calls, we discuss recent relevant literature and provide each other with feedback and support. We also liaise with the larger DARCLE community and discuss how their work might relate to our own. The DARCLE New Investigator group is a growing community. We welcome new members and ideas about how this group can engage novice researchers using the daylong recordings and the LENA System. To learn more about what our members are working on, please visit their sites. To join, please contact Hillary at
