His current research focuses on communities of extremophile organisms that live in temperate glaciers and salt deposit in the high plateau. These unique environments are experiencing in the past or are currently undergoing dramatic changes geophysicists. Many questions about ecology, evolution and physiology of these insects remain unanswered. Research efforts will emphasize molecular approaches to investigate aspects of population, evolutionary and physiological extremophiles in glaciers, salt deposit and other extreme environments. Also continue to explore its potential as environmental paleobioindicadores past and as climate proxies .
