Carlos B. Zavalaga began his career as a researcher on seabirds at Punta San Juan in 1992. At that time he began studying the Humboldt penguins and Inca terns. After obtaining his Bachelor (1992) and Professional Title (1997) in Biology at the Universidad Peruana Cayetano Heredia, he worked as a researcher at the Marine Institute of Peru in the Marine Mammal reserach unit. Between 2001 and 2008 he obtains Master's degrees in Biology and Ph.D. in Marine Biology at the University of North Carolina, Wilmington, USA., conducting foraging ecology research in three spp. of boobies (Sula spp.). In 2009 he travels to Japan to do a postdoctorate at Nagoya University, investigating mainly shearwaters and seagulls. Upon his return to Peru, he began working as a researcher at the Universidad Científica del Sur and as an independent environmental consultant. In his professional career he has studied different taxa of seabirds in Galapagos, Peru, USA, Japan, Italy, Argentina, Antarctica and Chile. He is currently developing different research projects in ecology, conservation and management that involve guano birds in Peru, polar skuas in Antarctica and gray gulls in Atacama-Chile. His main interest in seabirds is biologging for studies of the behavior of birds in the sea and the use of new techniques of biological monitoring.
