Research interests

My research is focused on Machine learning, deep learning and its applications in classification of abnormal lymphoid cells from peripheral blood digital images as a support in hematological diagnosis. This research is being carried out due to the cooperation between the Hospital Clinic of Barcelona and codalab group. I am also interested in applying convolutional neural networks and algorithms for classification when there is little data.
