ChangeLing Lab

ChangeLing Lab is Carnegie Mellon University’s only research lab focused on understanding how languages change, and how these patterns of change shape the way that languages are at any given point in time, from a computational perspective. We are interested in phonetics, phonology, and morphology (whether diachronic or synchronic), emergent communication, and have a special concern for the use of language science to benefit people with disabilities.

ChangeLing is lead by David R. Mortensen, an Associate Research Professor in the Language Technologies Institute. It consists, additionally, of graduate students, former LTI students who still collaborate with David, and visitors.

If you are interested in joining ChangeLing, please email David at dmortens@cs.cmu.edu with a CV and a description of what work you would like to do with us. Please take the following into account:

• We are only concerned with work that has some linguistic angle (either it uses linguistics or it is useful for linguists). Students who are concerned with machine learning for its own sake would be better served by another lab.
• We are interested in large language models, but only with respect to their language and linguistic reasoning capabilities. Our lab is not a good place to do general, engineering-focused or fundamental research on LLMs.
