From 1986 to 1994, first at the company PLANSEL S.A. and then at the Évora University, worked on Vitis vinífera clonal selection and on plant propagation techniques, especially table grafting of Vitis vinífera and Olive propagation by semi-hardwood cuttings. From 1994 to 2002, developed research for its PhD theses, on the subject of haploid production in Prunus species. From 2002 until now, it is working on plant propagation, and plant breeding. In vitro culture techniques for propagation of difficult to root plants, adventitious rooting anatomy and physiology, and breeding techniques to improve plant resistance against biotic factors, are themes of particular interest. Now it is working on anatomy and physiology of adventitious rooting in difficult to root olive cultivars, on in vitro culture of walnuts, and on the breeding of grapevine to improve resistance against powdery mildew.
