Given the question: Given the following context:  With the help of his Peruvian friend Ricardo, Oliver, an American hedge fund banker, buys debts owed by the Peruvian government to landowners.  Though the deals are lucrative, Ricardo has lingering doubts about whether they are helping Peruvians.  At the same time, Maria, a nurse at an underfunded hospital in Lima, cares for her elderly, ailing mother, Gloria.  Though Gloria needs hospital care, Maria can not convince her superior, Dr. Cerrón, to admit her, as Gloria's illness is not life-threatening.  In the Andes, a mountain farmer, Florentino, struggles to convince his neighbors not to sell their ancestral land to Caravedo, a developer who has promised to bring modernization and jobs to the area.  Florentino has a strained relationship with his son, Diego, who dreams of being a pilot. Oliver's boss, Nathan, tells him they need to pull out of Peru, as the company needs an immediate influx of money.  Stunned, Oliver insists Nathan give him time to close a potential deal with Caravedo that could solve their problems.  Nathan gives him one week.  Though his family is distraught that he is returning again to Peru, Oliver tells his wife he must close the deal or all of their previous sacrifices will be for nothing.  Oliver recruits Ricardo to research Caravedo.  After Oliver aggressively pressures the Peruvian finance minister to repay debts, Ricardo walks away from the Caravedo deal.  He returns shortly but demands Oliver promise to abort any potential deals with Caravedo if they turn out to be exploitative.  answer the following question:  In what location does Diego's dad work?
