Chrisnah (°1996) is a PhD student in linguistics within the CongUbangi project. His PhD dissertation focuses on the phonetics, phonology, morphology and syntax of Ndunga, an Ubangi (Mbaic) language spoken around Lisala in the Mongala province of the Democratic Republic of Congo. He studied Bantu linguistics at Marien Ngouabi University where he obtained his Master degree in 2021. For his Master dissertation, he did his first fieldwork to describe the consonant system of one variety of Luumbu (Bantu B44) spoken in the Republic of Congo. He then joined the Summer Institute of Linguistics (SIL) in 2021 where he worked for three years and half as a linguist whose main responsibilities included conducting fieldworks to write spelling and grammar guides, as well as dictionaries and lexicons of various Bantu languages (A80, B40,70, C20,30, 40, H10). During his time at SIL, Chrisnah has done linguistic fieldworks and participated in grammar-based workshops in the Republic of Congo, the Democratic Republic of Congo and Kenya. Moreover, he acted as part time teacher at Marien Ngouabi University (2022-2024) in General Linguistics, Phonology, English Grammar and Intensive Oral Language.
