Miembro Fundador PeruBiotec

PhD, MIP (Law), Abogado en propiedad intelectual

Cargo actual: Consultor Principal, Ag RD&IP Consult P/L

Jorge Mayer Jorge nació y se crió en el Perú. Cursó estudios superiores en Austria, donde se doctoró en Química y Bioquímica. A lo largo de su vida profesional ha trabajado en Alemania, Colombia y Australia, y siempre convencido de los beneficios que aporta la transferencia tecnológica para los países en vías de desarrollo, tales como su propio país de origen. Por muchos años ha contribuido a la generación y transferencia de tecnologías en el área de la biotecnología agrícola, como por ejemplo cuando trabajó en el Centro Internacional de Agricultura Tropical en Colombia o para el proyecto del Arroz Dorado, un proyecto de especial importancia para el sudeste asiático. Su especialidad adicional en propiedad intelectual lo posiciona idealmente para efectos de transferencia tecnológica.

Primer ensayo de campo con Arroz Dorado 2005 Con Peter Beyer, uno de los inventores del Arroz Dorado, durante el primer ensayo de campo en Louisiana, en el 2005. En aquel entonces el ensayo no se pudo hacer en el Asia, donde vive la mayor cantidad de gente que se beneficiará de este alimento biofortificado, por la falta legislación en bioseguridad. Hoy en día, países como Filipinas y la India por suerte ya cuentan con una regulación funcional, la que permite hacer ensayos de campo y comercializar cultivos transgénicos.
