In 2012, Bobaljik published a book (Universals in Comparative Morphology: Suppletion, Superlatives and the Structure of Words) on universals in comparative constructions, where he proposes the Comparative-Superlative Generalization. This book was awarded the Linguistic Society of America's Leonard Bloomfield Book Award.[6]
Bobaljik has worked extensively on the critically endangered Itelmen language.[7] He has participated in the development of an Itelmen-Russian dictionary,[8] its mobile app,[9] and is currently working on an audio and video dictionary of the language.[10]
