Originally trained in Agronomy, Dr. Podestá has recently become involved in studies of ENSO-related climate variability and applications of seasonal-to-interannual climate predictions to enhance decision-making in climate-sensitive sectors of society such as agriculture.

Dr. Podestás interests also include satellite remote sensing of ocean dynamics using sea surface temperature, ocean color, and sea surface height fields; applications of satellite and in situ observations to the understanding of oceanic variability and biological responses. He has previously written on fishery oceanography and fishery ecology.
