Before coming to Europe and the United States for graduate studies, I worked in the Manila offices of two of the world's largest financial services group and in one of the top national security agencies of the Philippine government.

Currently based in the Netherlands, I have resided in the Philippines, Germany, and the United States for extensive periods of time, and I have traveled for work and leisure in Europe, North America, and Asia. 

My online library catalog can be found here. I only listed the hard copy version of the books that I acquired over the years. I maintain these book collections in the Philippines and the Netherlands.
