photo neededIn hmolscience, Dimitri F. Katakis (c. 1950-) is a Greek psychologist noted, in psychological thermodynamics, for his 1978 to 1986 theory, developed with with Charis Katakis, of teleonomic entropy or goal-directed or purposefulness entropy.

Overview
In 1978, Katakis, together with Charis Katakis, according to Kenneth Bailey, began applying the concept of entropy, in the general sense, to psychotherapy. [1]

In 1982, Kimitri Kataks, together with Charis Katakis, in their “Teleonomic Entropy in Biopsychosocial Systems”, hypothesize a teleological-themed entropy, or entropy antonym, the abstract of which is as follows: [2]

“The concept of entropy has been developed from, and has usually been applied to, systems on one level. Due to its unifying potential, however, interest in applying entropy to, complex multilevel systems as well has recently increased. The concept's distributional and statistical formulations, nevertheless, have little relevance to the apparently purposeful, decision-making properties of complex living systems. In order to make it more suitable for understanding the functioning of such biopsychosocial systems (particularly organisms, groups, organizations, and societies), its definition has to be extended. This paper introduces the new concept of teleonomic entropy. In order to distinguish this generalized concept from that of thermodynamics and statistical mechanics, we shall refer to the latter as physicochemical entropy. Teleonomic entropy at the physicochemical level is related to, but not identical to, physicochemical entropy.”

Education
Katakis completed his PhD in psychology from the University of Thessaloniki.
