Art Miller is a Research Oceanographer (equivalent to Full Professor) and a Senior Lecturer in Climate Sciences at Scripps Institution of Oceanography (UCSD). He is also currently Head of the Oceans and Atmosphere Section, which includes the CASPO Division and MPL.  He is a physical oceanographer who studies oceanic influences on climate variability using a combination of computer simulation models and observational analysis. He also is increasingly involved in working with biologists to try to understand how physical oceanographic changes affect oceanic ecosystems. He is the author or co-author of more than 100 refereed publications and has had funding from NSF, NOAA, NASA, ONR, DOE, and the CA Dept of Boating and Waterways. He typically advises 2-8 Ph.D. students.

His research extends from basic issues in dynamical oceanography to a variety of topics in climate dynamics, atmospheric dynamics, coupled ocean-atmosphere interactions, ocean data assimilation, regional impacts of global climate change, and oceanic ecosystem response to physical forcing. His earlier papers involved the field of Pacific decadal variability. His recent interests include diagnosing climate regime changes in the physics and biology of the California Current, assessing the impact of climate changes on marine ecosystems in the North Pacific, and assessing the impact of mesoscale sea surface temperature anomalies on regional coupled ocean-atmosphere variability.

He is frequently invited to speak at conferences, workshops, and institutions around the world. He has previously served on the Scientific Steering Committees of the U.S. Global Ocean Ecosystems Dynamics Program (GLOBEC) and the Bering Sea Ecosystem Study (BEST) Program. He has also served as Co-Chair of the U.S. CLIVAR Phenomena Observations and Synthesis (POS) Panel and been a member of the international panels of VAMOS Ocean-Cloud-Atmosphere-Land Study (VOCALS) Modeling Group and PICES Evaluations of Climate Change Projections Working Group. He is also a former member of the U.S. CLIVAR Pacific Implementation Panel.  He is an Associate Editor of Atmospheric Science Letters (Royal Meteorological Society) and previously was Associate Editor of the Journal of Geophysical Research-Oceans (American Geophysical Union). He has also served as a referee for dozens of scientific journals and various national and international funding agencies.
