Data Sciences for the 21st Century (DS421) is a two-year interdisciplinary graduate training program whose mission is to train a new generation of scientists to tackle grand challenges at the intersection of natural, social and data sciences by translating data into evidence-based analysis of impacts and solutions in the face of rapid environmental change. The DS421 program is open to incoming and first-year PhD students from all departments, and from select on-campus Master’s programs. A number of second-year fellowships for PhD trainees are available from the DS421 program, providing a full stipend ($32,000) plus tuition and fees. Applications are also welcome from students who have received independent fellowships from other sources that support them for this period in their career (Berkeley, NSF, International, etc.). Conference travel funds, seed grant funding, and other activities will be available to all trainees. Applicants should have a background in one or more of the following areas: natural or environmental science, social science, public policy, landscape architecture, environmental planning, statistics, environmental law, computer science, or related fields. Applications will open in February, awards will be announced in April. See the Data Sciences website for more information.
