JCF obtained his undergraduate degree at the University of Brussels in 1959. In the course of his graduate training, which also took place at the University of Brussels, he became interested in mathematical psychology, and also in applied (industrial) psychology. He received his Ph.D. in 1965. The topic of his dissertation concerned the construction and the application of stochastic models for reaction times. Between 1966 and 1969, JCF held a number of post doctoral positions and visiting appointments at various universities in the US (University of Pennsylvania, University of Wisconsin and University of Michigan). During that period, his scientific interests grew larger, and he started investigating some theoretical problems in psychophysics and measurement theory. He went back to Europe in 1969 and taught at the Universities of Brussels and Paris for a couple of years. In 1971, JCF returned to the US as a Professor of Psychology at New York University. He remained at NYU until 1989, when he joined the Department of Cognitive Sciences and the Institute of Mathematical Behavioral Sciences at the University of California at Irvine.

Research

My research is marked by a systematic effort to apply mathematics, and in particular the axiomatic method, combinatorics, functional equation techniques, and probabilistic models to the analysis of behavioral science phenomena. This led me to work mostly in six areas, with substantial temporal overlap. The first four of them pertain to classical topics of research for mathematical behavioral scientists. As made clear by the bibliography section, many of the papers and the majority of the monographs or edited volumes mentioned below were co-authored with colleagues or students. My collaboration with Jean-Paul Doignon, with whom I have worked since the beginning of our respective careers, is especially noteworthy.

Reaction latencies. Around 1955, there was much interest in understanding the effect of the probability of stimuli on the reaction latencies. A popular model at the time was based on information theory in the sense of Claude Shannon, with the concept of the human subject as a channel of communication. This lead to relate average reaction latencies to stimulus probabilities via entropy measures. Using stochastic models inspired by those in vogue in learning theory, I was able to show that these probability effects were, at least in some situations, entirely explainable by sequential effects (see [1], [2], [6], and [11]).

Psychophysics. On a ground well prepared by the work of Luce and Galanter, I strived to formalize classical Fechnerian psychophysics in a modern language influenced by the progress in measurement theory and also benefitting from functional equations techniques. This led to experimental work extending classical results and to the proposal of a new psychophysical law in [75]. The following other papers are relevant to this line of research: [4], [8], [9], [12], [13], [16], [18], [24, [33], [34], [60], [62], [75], [88], and [95]. Much of this work is summarized in the long paper [60] and in the monograph [B1] published in 1985, which was revised and reprinted in 2002.

Measurement theory and philosophy of science. In the line of works by Luce, Suppes, and others, I have developed axiom systems for various fundamental measurement structures. One preoccupation, prompted by applications in the behavioral sciences, was the case in which the domain of the measurement structure was bounded on both sides, that is, bounded above and away from zero. Relevant papers are [5], [7], [9] and [10]. Any fundamental measurement structure is an ordered structure which can be formalized in a variety of ways depending on the situation, merging thus fundamental measurement theory with combinatorics. Several papers describe results my efforts in this area (cf. [3], [23], [29], [30], [36], [51], [56], [67], [80], and [91].) I also tried to give a theoretical account of possible errors of measurement by extending the framework of fundamental measurement to include probabilistic representations (see [12], [14], [17], [19], [22], and [31]). An essential concept in the formal description of scientific theories, related to measurement, is the `meaningfulness' of scientific statements (such as the physical laws), that is, the invariance of such statements with respect to changes of the units of the variables. Typically, from a strictly formal standpoint, common scientific statements are not meaningful in that sense. Their invariance is implicit, rather than intrinsic to the formalism. First in [25], written with Louis Narens, and then more systematically and with more generality in [90], I have began the development of a formal framework for the statement of meaningful scientific statements. Such a framework leads to more general axiomatizations of the theories, possibly giving a better insight on their empirical foundation. Much remains to be done in this area, such as clarifying the relationship between meaningfulness and dimensional invariance.

Probabilistic choice theory. In static choice, that is, without consideration of a possible temporal evolution, the most notable result is presented in [15], in which I solved a problem of representing multiple choice probabilities by inequalities involving random variables. This problem was raised by the economists Block and Marschack almost 20 years earlier. Other papers in the same category of static choice are [14], [26], [47], [49], [50], [59], [64], and [74]. Probabilistic choice can also be studied from the standpoint of the evolution of preferences over time, leading to stochastic models of choice. A particular application concerns the the evolution of the preferences of potential voters in a political election, as revealed by panel data. Relevant papers are [66], [68], [70], [72], and [98].

The last two areas are original endeavors.

Knowledge spaces and learning spaces. The foundation paper is [32], written jointly with Jean-Paul Doignon. We presented there a formal framework for the assessment of knowledge, for example of students learning arithmetic or algebra. This framework was combinatoric in character, and as such insufficient for a practical assessment, which is unavoidably plagued with careless errors on the part of the test takers. This paper was the beginning of a systematic development which is continuing today. Many papers were written, dealing with all the pieces of a practical assessment system. In particular, it was essential to create a stochastic framework for the description of the evolution of an assessment, question by question. Many papers in the reference section are relevant to this development. The high points are [35], [41], [42], [43], [48], [57], [58], [71], [76], [82], [93], [99], and [100]. Much of the results are presented in the monograph [B4], by Doignon and Falmagne. (A much expanded revision will be published as [B7].) This work led to the creation of a web based system called ALEKS which is used today in more than 700 schools and universities in the US and abroad. This line of research is now being pursued by many investigators mostly in Austria, Germany, and the Netherlands.

Media Theory. Mathematical structures used in both knowledge space theory and combinatoric choice theory can be generalized in the form of a semigroup of transformations on a set of states. This system is defined by two axioms and is called a {\sl medium}. Such a generalization is not gratuitous because it enables many results obtained in media theory have applications in many diverse mathematical structures. For example, a learning space can be represented as a special case of a medium. The main papers describing the results are [69], [77], [85], [87] and [97]. A monograph on this subject, jointly written with David Eppstein and Sergei Ovchinnikov, has been published by Springer (see [B6]) .
