Athula Buddhagosha Attygalle (Sinhala: අතුල ආටිගල) is a Sri Lankan scientist who works as a professor in the field of mass spectrometry in the United States.

[4] After his doctorate, Attygalle was awarded a fellowship by the Humboldt Foundation to conduct research at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) under Hans Jürgen Bestmann, a pioneer in the field of insect pheromone synthesis.

Four years at FAU provided the impetus for Attygalle to become an expert in high-resolution mass spectrometry and micro-chemical techniques for structure elucidation of natural compounds at nanogram level.

[5] Currently Attygalle is attached to the Stevens Institute of Technology as a Research Professor in the Department of Chemistry and head of the mass spectrometry laboratory.

[7] Attygalle co-authored the 1999 article "Single-Site Catalysts for Ring-Opening Polymerization:  Synthesis of Heterotactic Poly(lactic acid) from rac-Lactide" in the Journal of the American Chemical Society, which has been widely cited.
