As a librettist, Robert creates impactful and entertaining works that have been described as “relatable and fresh.” His comedies are noted for being “quick-witted and layered”, and his horror as “hauntingly engaging.” Recently, Feng was a speaker at the 2025 OPERA America Conference in the panel “In Search of the Perfect Libretto.”

Feng’s first opera Having Guests for Dinner is a 1-act horror/comedy with music by Nick Bentz. It premiered virtually with New Opera West in 2020 and has since been produced at Hartford Opera Theater, Central Washington University, and Hillman Opera at SUNY Fredonia. The full length version was commissioned and co-produced by Kor Productions. Feng and Bentz’s second opera Salmo, a grand space opera in four acts, will be workshopped by Brown University for their 2026/27 Academic Year. 

Other operatic works include the supernatural horror opera You Do Not Recognize the Bodies in the Water workshopped at OPERA America in 2022 with music by Felix Jarrar, and the political satire Chew On This with music by Yunfei Li commissioned by Lyric Opera of Kansas City and No Divide KC for their Come As You Are (CAYA) Festival. Chew On This was described as “truly an operette for our times” (S. Fairbank). Upcoming projects include the Sci-Fi operetta Pathfinder with music by Jane Kozhevnikova, Annihilation: A nuclear oratorio for the end of days with music by Scott Wheeler, Extinction Event with music by Meilina Tsui, and The Ming and I, commissioned by Boston Opera Collective for their 2026 Opera Bites Showcase with music by Ben Yee-Paulson.
