Hola.

Maybe you need \commalistsentence?

\def\Autores{%
  {Luis David Gómez-Méndez, Ph. D.},
  {Adriana del Pilar Pulido-Villamarín, M. Sc.},
  {Rubiela Castañeda-Salazar, M. Sc.},
  {Juan Carlos Ulloa-Rubiano, Ph. D.},
  {Adriana Matiz-Villamil, M. Sc.},
  {Fidson Juarismy Vesga-Pérez, Ph. D}%
}
\starttext
\commalistsentence[\Autores][{;\space},{\space\letterampersand\space}]
\stoptext

Check lang-lab.mkxl for other goodies and examples.

Best regards,

Jairo
