My research is about conceptually simple and inexpensive experiments but of great scientific and technological relevance. In this style of research, not only is it possible to collect and interpret the results of an experiment, but it is possible to quickly design and construct an experimental arrangement. In addition, the results obtained in the laboratory can be compared with the theoretical predictions or building mathematical models to understand the observations. Under this approach, I have carried out studies in granular media, colloidal systems, the formation of works of art (such as sand drawings and watercolor paintings); and the study of patterns formed from the evaporation drops. This with the aim of detecting contaminants, protein, and structural changes in cells.
