ResearchDr. Klein's research focused for many years on the epidemiology and clinical manifestations of HIV infection. He has contributed to our understanding of routes of HIV transmission, especially among heterosexuals, injecting drug users, and health care workers. He has studied the clinical complications of HIV infection including opportunistic and other infections, such as tuberculosis, pneumocystis, syphilis, human papillomavirus-associated genital neoplasia, and others. His most research has focused on hepatitis C and disorders of aging as they affect patients with HIV infection.
