Lluís Brines' main research line has been Francesc Eiximenis' thought and works.
Lluís Brines' research about Francesc Eiximenis began with his doctoral dissertation, after getting his degree in Law in the University of Valencia.
It analyzes Francesc Eiximenis' works and thought from a social, political, economic and only in some respect, in spite of the title, legal point of view.
[1][2][3][4][5][6][7] It was reprinted in the review Estudios Franciscanos (Franciscan Studies) between 2006 and 2007 (with an enlargement of a short biography of Francesc Eiximenis).
[10][11][12][13] In 2009 he worked together with philologist Josep Palomero in an edition with modern language of Francesc Eiximenis' classical book Regiment de la cosa pública (Government of the Republic).
[22] Since 2017 he collaborates with the Biographisch-Bibliographisches Kirchenlexikon (BBKL), which is a digital encyclopedia in German language about Christian persons related to the history of the church, philosophy and literature.
The selected people stem from the fields of Christian theology, history, literature, music, painting, pedagogy and philosophy.
[24] Lluís Brines was the ideologist and creator of the website antiblavers, whose main aim was to fight in a scientific and serious way against Blaverism.
[26] One of the most important milestones of the website during its first years was the gathering of old and modern evidences of the flag with four red stripes in Valencian territory.
Maybe one thing that made Blaverists very upset was the success of the campaign that was done by the website antiblavers, in collaboration with the antifeixistes website in order to avoid the presence of the GAV (Group of Valencianist Action) in the Christmas fair Expojove during the Christmas of 2010.
Moreover, the project was divided into two websites: The first important Blaverist attack against Lluís Brines took place in December 2010, when in his old address in Valencia some graffiti appeared with his name and surname and the words "paederast" and "paedophile".
The graffiti was allegedly made by the former co-president of the Youths of the GAV (JJGAV) Aitor Alan Marquina Bañuls.
[30] A bit later, in January 2011, other graffitis appeared in Simat de la Valldigna (Safor), the village of Brines' paternal family, where he was also called "paederast" and "paedophile".
[32] was finally condemned in 2018 to pay a fine of 600 €,[33][34] and since then he ceased to attack Lluís Brines and even to write in the Blaverist and far-right website valenciafreedom.
