William from Guatemala has a passion for science and volunteering that has led him to focus his life on it. Four years ago, he created the initiative "Yo Por Ti". Their work has focused on reducing inequalities and human rights, both for the elderly and children in need. The initiative has supported donations and activities in many places and has caused a tremendous impact on people. Now he would like to lead the project in the creation of immediate response groups in communities that are vulnerable to natural disasters, to reduce humanitarian losses.
