Since 1995 he has written critical material on Kafka, Goethe, Kleist and Holderlin in cooperation with the Department of German Studies.
Nervi first gained renown for his poems when he was only 18 years old, and 1978 saw the publication of his first collection La turoj de l' ĉefurbo ("The Towers of the Capital").
After the publication of his first book, Nervi continued to write poetry, which appeared in several literary reviews including Fonto and Literatura Foiro.
In 1986 his translation in Esperanto of Il repertorio della memoria by Eugenio Montale was used as the introduction to Spomenka Štimec's novel Ombro sur interna pejzaĝo.
Leaving behind the classical themes of La turoj de l' ĉefurbo, Havenoj contains much sea imagery and was also inspired in part by his studies of German literature, for which he received his second doctorate.
