My research activity began in 1989 with my postgraduate studies. My doctoral thesis was devoted to the study of relationship between the structure and optical properties of crystalline materials and especially to studies of optical activity. In that work I put into operation a new type of polarimeter called High Resolution Universal Polarimeter (HAUP).
Later I started working in the field of liquid crystals (LC) but without abandoning the previous research activity. Specifically, my work in liquid crystals has focused on the characterization of non-conventional LC phases by means of optical measurements and X-ray diffraction. One of the most outstanding lines of my research activity has been the study of nonlinear optical properties of LCs. In this sense, my work consisted in the implementation of different experimental systems for the measurement of second harmonic generation (SHG) and SHG interferometry.
I have also contributed with more than 75 articles in international magazines and 50 communications in international congresses.
I have supervised 4 doctoral theses, a dissertation for PhD, a DEA and a Final Master's Project. One of the doctoral theses I supervised was awarded the Glenn Brown International Prize for the best thesis in liquid crystal physics granted biennially by the International Society of Liquid Crystals.
