From 1920 to 1926 he was attached to the College of Agriculture in U.P., and from 1926 to 1928 to the University of California; in 1928 appointed systematic botanist and since February 1934 acting chief of the Natural Museum Division of the Bureau of Science, Manila, now director of the National Museum. When assigned to the U.S. Navy in Guiuan, at the southern tip of Samar, made collections in that region. He retired as director in November 1961, and was for some following years attached to the Araneta University. Quisumbing undertook restoration of the Herbarium, which was completely destroyed during the war.
Quisumbing was author of taxonomic and morphological papers, many of which deal with orchids, including ‘Medicinal plants in the Philippines’ (Manila 1951). Saccolabium quisumbingii has been named in his honour.
