## Reshaping the World: A Systematic Unified Framework for Conceptual Engineering (SUFCE)

The purpose of the SUFCE project is to develop a well-founded systematic uniﬁed framework for conceptual engineering, that is: a method for the cognitive optimization of our conceptual apparatuses, based on adequate theories of concepts and of (cognitive) engineering.

## Postdoc Research Project #2

## Sign, Meaning, Reference (SIMERE).

## A Semiotic Epistemology for Conceptual Engineering

The purpose of the SIMERE project is to provide new foundations for the epistemology of semiotic systems by modeling a theory of referential meaning that methodologically justifies the possibility of semiotic cognition as a dynamic process from the dual standpoint of intension and intentionality, with direct applications and a broad spectrum of outreach in conceptual engineering.

## Postdoc Research Project #1

##

## Husserl's Epistemology and Semiotics

## of Mathematical Logic

The purpose of this research project is to contribute to a re-assessment of the significance of Husserl's philosophy of logic and mathematics, and to establish connections to it and some mainstream challenges in modern epistemology of mathematical logic by endorsing a semiotic-intentional viewpoint—viz. in terms of symbolic knowledge.

## Sémiotique, syntaxe, sémantique (1879–1901). Des conséquences de la modélisation du signe sur la théorie de la signification chez Frege et Husserl

My dissertation is a work in historical epistemology of language sciences. It deals with the redefinition of semiotics that occurs at the turn of the 20th century in correlation with the development of new formal languages for the modern, mathematically oriented logic. In that context, it focuses on the constitutive conditions of Frege’s logicist program (1893) and Husserl’s idea of phenomenology (1913). While aiming to determine the impact of their semiotic models on the development of their theories of meaning, it provides a chronological and systematic reconstruction of their conceptions of logic from 1879 to 1901. And in so doing, it leads to setting up an alternative between two ways of relating a calculus to its signification (either monistic or dualistic), correlated with two opposite views on semiotic meaning (either intensional or extensional), and entailing two different conceptions of logic (either as calculus or as language). Thereby, my dissertation contributes laying out the syntax-semantics dichotomy that underpins the rise of modern logic.
