Employment

August 2001 to present University of Hawaii, SOEST/IPRC
Assistant Researcher. Reseach is being conducted within IPRC Theme-2; GOAL 2: To determine the influences on Asia-Pacific climate of western-boundary currents, the Kuroshio/Oyashio Extension system, marginal seas, and the Indonesian Throughflow.

July 1999 to July 2001 University of Washington, School of Oceanography
Research Associate Post-doctoral. Present research involves analysis of data collected in the Indonesian Seas in conjunction with numerical model experiments to investigate aspects of the Indonesian throughflow.

September 1998 to June 1999 International Pacific Research Center (IPRC)
Post-doctoral Researcher. Research involved study of ocean processes in the western equatorial Pacific and eastern Indian Oceans and their relationship to climate variations on timescales from seasonal to interannual.

August 1992 to August 1998 The University of Hawaii
Graduate Assistant. Research involved numerical model/observation intercomparison to study dynamics of the western equatorial Pacific. Results from general circulation models are used with various remote and in-situ data to gain insights into various aspects of ocean circulation and water mass mixing in the western Pacific. Specific interest involves running experiments with a numerical model to determine the factors controlling the annual cycle of mass transport between the Pacific and the Indian Oceans via the Indonesian throughflow. Additional responsibilities include administration and system maintenance for two Silicon Graphics workstations.

August 1990 to August 1992 Hughes STX Corporation
Senior Scientist. Provided research support for NASA scientist doing numerical ocean modeling. Involved in studying ocean mixed layer schemes and their relation to a general circulation model. Primary focus was on the equatorial Pacific with an effort to understand the Pacific warm pool. Additional responsibilities included administration and system maintenance for Silicon Graphics IRIS and CDC 4340 workstations and the development of graphics software for the analysis and display of large scale data sets.

September 1988 to August 1990 The Florida State University
NASA Traineeship. Used a numerical model of the Indian Ocean to study the seasonal circulation in the Bay of Bengal. Model experiments were run on a Cray Y-MP supercomputer and the results were displayed using color animation with a Silicon Graphics workstation.

June 1986 to September 1988 Atlantic Research Corporation
Associate Staff. Provided support to the Ship Performance Department (Code 15) of the David Taylor Research Center (DTRC) in Bethesda, Maryland. Work for the Ship Dynamics Branch (Code 1561) included the development of a graphic output program for ocean environment effects on vessels (US Navy's Tactical Environmental Support System); participated in the study of ocean wave data and theory for navigational guidance for the USS Midway; and conducted research on the Environmental Monitoring and Operator Guidance System (EMOGS) for submarine navigation of the channel at King's Bay, Georgia. Work for the Ship Dynamics Branch (Code 1563) included the incorporation of a depth changing algorithm into the current submarine simulation routine; incorporated a new weapons configuration into the simulation algorithm; and analyzed ship control problems for SSBN submarines.

June 1985 to September 1985 Atlantic Research Corporation
Technical Staff. Generated structured mathematical documentation from computer code governing SSBN submarine ship control simulation.
