Modeler

Modeler is a term used to describe a person who constructs models or a software tool that enables modeling. A model is a simplified representation of a system, object, or phenomenon designed to analyze structure, behavior, or relationships and to communicate ideas. Modelers work across disciplines, applying abstract representations to guide design, research, or planning.

Professional modelers may specialize in physical modeling, building scale replicas of machines, buildings, or landscapes, or in virtual modeling, creating digital representations in 3D space, CAD, or parametric modeling. In data science and software engineering, a modeler develops mathematical, statistical, or computational models to explain data, predict outcomes, or simulate processes.

Modelers contribute to product development, architecture, animation, research, and operations research, among other fields. They use a range of tools, from traditional drafting and physical prototyping to computer-aided design software, 3D modeling programs, and data-modeling platforms. Common approaches include geometric, statistical, and agent-based modeling.

Education and training typically cover mathematics, computer science, engineering, or a domain discipline, with instruction in modeling methods, validation, and documentation. Successful modelers combine analytic reasoning with clear communication and the ability to translate complex systems into accessible abstractions.

Different industries may use the term differently; some contexts refer to a specific software product named Modeler. This article uses the general sense of the term.
