I obtained my M.Sc degree at the Physics Department of the University of Patras, Greece and then my Ph.D in April 2015. My thesis was entitled “Observational study and modeling of close eclipsing binary stars of W UMa type” (supervisor Assistant Professor E.P Christopoulou). As a doctoral candidate I observed and investigated eclipsing binary stars (EBs) with peculiarities, third bodies and mass transfer and developed automated pipelines to model their physical properties and investigate eclipse timing variations.

As a fellow I plan to reveal the principal parameters and the statistics of EBs on data from Catalina Real-time Transients Survey and the Vista Variables in the Via Lactea ESO Public Survey, by applying time domain astronomy techniques and non-linear modeling methods.

Obtuve mi Magister en el Departamento de Física de la Universidad de Patras, Grecia y luego mi Doctorado en abril de 2015. El título de mi tesis fue “Observational study and modeling of close eclipsing binary stars of W UMa type” (Profesor Asistente supervisor E.P Christopoulou). Cuando estaba realizando mi doctorado me dediqué a observar e investigar estrellas binarias eclipsantes (EBs) con peculiaridades, terceros cuerpos celestes, transferencia de masa y desarrollo de pipelines automatizadas para modelar sus propiedades físicas e investigar variaciones de tiempo eclipsante.

Como investigador planeo demostrar los parámetros principales y las estadísticas de EBs en datos del Survey Catalina Real-time Transients y del Survey público Vista Variables in the Via Lactea de la ESO, por medio de técnicas de la astronomía de dominio temporal y métodos de modelamiento no lineales.
