Luis J. Goicoechea es profesor de astronomía y astrofísica en la Universidad de Cantabria (UC). Su tesis doctoral trató sobre observaciones en algunos modelos cosmológicos inhomogeneos. En la segunda mitad de la década 1980, el y otros físicos teóricos españoles se incorporaron al campo de la astronomía/astrofísica. En dicha época también se consolidan los principales institutos y observatorios en España, se dan los primeros pasos de la comunidad nacional en programas espaciales y se produce el crecimiento generalizado de la astronomía española. Ha dedicado una gran parte de los últimos 25 años al estudio de sistemas lente extragalácticos, i.e., cuásares distantes que sufren efectos lente gravitatoria producidos por galaxias más próximas. Esta investigación se concentra básicamente en estudiar la estructura de núcleos galácticos activos lejanos (entorno de agujeros negros supermasivos en épocas remotas) y de galaxias a distancias intermedias, así como la expansión y contenido del Universo como un todo, y se desarrolla en el marco del proyecto GLENDAMA (Gravitational LENses and DArk MAtter). Actualmente, GLENDAMA utiliza instrumentación avanzada para crear una base de datos de alta calidad sobre la variabilidad de varios cuásares que sufren efectos lente. Principalmente el telescopio Liverpool, que tiene 2 metros de diámetro, funciona de forma robótica y está situado en la isla de La Palma (Islas Canarias, España).Las últimas novedades y resultados se incluyen en la nueva web https://gravlens.unican.es.
