You can find more information about Pahari, here: Britannica article. Pahari refers to “of the mountain,” and it is an umbrella term for all the different languages and dialects spoken throughout the Himalayan mountain range in Northern India. The dialect that his family speaks is best described as a distinct combination of both Hindi and Punjabi. Those were the initial languages that Kartik was exposed to since birth, and he learned English when he moved to the US. As a result, some of the interest in this lab stems from curiosity about language development in a multilingual environment.

He is a huge music nerd, and likes listening to a variety of different genres of music. His top 3 favorite genres are Indie-Rock, R&B, and Electronic music (If you want music recs, his top three songs at the moment would be: “I’m This” by Peter Cat Recording Co., “Jasmine” by Jai Paul, and “Champagne Coast” by Blood Orange).
