Research
Falissard has worked on statistics, psychoanalysis and child and adolescent psychiatry. In statistics, he found how to represent optimally a correlation matrix by points on a 3-dimensional sphere. This representation preserves the topological structure of the correlation matrix and is more accurate than the more classical Principal Components Analysis. From the end of the XXth century to the mid of the 2010s, Falissard did research in epidemiology (as the co-principal investigator of mental health in prison study and in methodology of subjective measurements in health and in particular in psychopathology. In particular he developed an outcome measure in schizophrenia, which made it possible to show that "in patients with schizophrenia, symptoms improvement can be uncorrelated with quality of life improvement." After that he engaged more in the epistemology of mental health research, and took many positions in the national media (the questionable place of genetics studies in psychiatric research, the potential misuse of medications in child and adolescent psychiatry, the insufficiency of health policies in child and adolescent psychiatry, the inappropriate importance of the place of neurosciences in psychiatric training. For his research in the field, he was awarded the Ülkü Ülgür International Scholar Award by the American Academy of Child and Adolescent Psychiatry in 2019.

Falissard published a series of papers addressing psychiatric disorders, disability, mental health or subthreshold manifestations. While emphasizing on the importance of early detection of child and adolescent mental disorders, he discussed potential problems with early detection of mental disorders in youths, and also highlighted clinical, psychological, societal and economical factors that can render the effective early detection programs a complete failure. In 2015, he focused his studies on evaluation processes of non-pharmacological treatments in child and adolescent psychiatry, and questioned biology as the only theoretical framework relevant in medicine and psychiatry, and quantitative approaches (particularly randomized designs) as the only standards for evaluating treatments. Moreover, he emphasized how the construct of "Neurodevelopmental disorders" can be problematic in our understanding of some child and adolescent psychiatric disorders.

In 2020, during the COVID pandemics, Falissard criticized the anxiety-provoking nature of the discourse of psychiatrists in the media. In his interview with Juliette Parmentier, he discussed the impact of the COVID-19 crisis on the mental health of young people, and stated that for the 16-25 year old "The main problem for this age group is the total lack of recognition of their sacrifices."
