Biography
Karim is a Peruvian researcher who has been working since 1997 on the first study on the reproductive ecology of South American sea lions (Otaria byronia) in Peru. The main goal of her research is to determinate the impact of El Niño events on this species. She graduated from UBC in 2005.
