For his Advanced Postgraduate Studies Diploma, Larys Frogier intellectual work focused specifically on the intersections between art and politics during the AIDS epidemic, a period in which he analyzes the convergence of artistic practices and activist strategies. Considering the AIDS activism as a decisive social and cultural practice for giving people access to treatment, he also examines how AIDS was also a major crisis of representation in social contexts and in the contemporary arts communities.
Enrolling in ACT-UP Paris activities while researching on emerging North American collectives such as Gran Fury, Diva TV, Democracy Next co-founded by Felix Gonzalez-Torres, as well as giving tribute to the art critics and cultural activists such as Douglas Crimp and Simon Watney, Larys Frogier analyses how disrupted visual representations, forced the visibility of marginalized bodies, and transformed the artist's role into that of a political actor.

Following his diploma, his key contributions include:
. The essay "Résister en corps dans la crise du sida" (Resisting through the Body during the AIDS Crisis), published in the proceedings of the Images de la maladie 1790–1990 symposium.
. The essay "Homosexuals in the AIDS Crisis in France: Integration, Denial, Activism," presented at the Institute of Contemporary Art in London.
. The essay "Repräsentation, Identität und Minoritär-Werden: Die Anti-AIDS-Bewegung in Frankreich," published in German in the journal Texte zur Kunst.

These works are part of a broader inquiry into how anti-AIDS activism—particularly through groups like Act Up—borrowed visual strategies from contemporary art to create a political and social counter-representation.
