. She pursued post-doctoral work at Johns Hopkins during the 1970s, working first with Bernard Weiss and then with Opendra "Bill" Narayan and Richard T. Johnson. Along with Diane Griffin and others, Clements was one of several trainees of Johnson who went on to notable academic careers at Johns Hopkins. Clements became a faculty member at Johns Hopkins in 1978 as an assistant professor in the Department of Neurology and became a full professor in 1990, the 24th woman to achieve this rank at the Johns Hopkins School of Medicine. Clements joined the Division of Comparative Medicine in 1988 and headed its retrovirus laboratory from 1992. Clements successfully convinced the school to elevate the division to department-level status, and in 2002 became the first director of the new department, later renamed the Department of Molecular and Comparative Pathobiology. In 2000, Clements was appointed vice dean for the School of Medicine, taking over the duties of Catherine D. DeAngelis, who had left Johns Hopkins to become the first woman editor-in-chief of the ''

Research

Clements has conducted and led research into numerous viruses, concentrating on the animal lentiviruses. Lentiviruses are a complex type of

At the time, the origin of HIV was unknown, and Clements' work presented the possibility that HIV could have been transferred to humans from animals. Later, it was found that

Advocacy

Clements has advocated and fostered the creation of opportunities and supportive environments for women in academia. She is a member of the steering committee of the Johns Hopkins Women's Leadership Council. In 2005, the Johns Hopkins School of Medicine celebrated the promotion of the 100th woman to the rank of full professor in a ceremony organized by Clements and others at Johns Hopkins. The event was entitled "The Legacy of

Garrett herself had stressed the importance of equal opportunity in medical education, specifying that the school must allow women and men alike to seek admission and "prizes, dignities or honor that are awarded by competitive examination, or regarded as rewards of merit."
