Born in the Copenhagen suburb of Gentofte in 1946, Albert Gjedde spent time as an undergraduate student in Berkeley, California, United States (1964–65, 1968), Stellenbosch, Cape Province, South Africa (1968), and Lexington, Kentucky, US (1969).

As a junior investigator, Albert Gjedde worked as a visiting scientist at universities or research institutions in Lund, Sweden; Cologne, Leipzig, and Dresden, Germany; Paris, France; Szeged, Hungary; and Baltimore, Maryland, United States.

He uses PET to understand the synthesis of radioligand and tracer molecules that match the neurotransmitter molecules and the behavior of these transmitters under different functional conditions of the brain, normal as well as pathological, and the spatial and temporal relations among changes of cerebral blood flow, which is commonly used as a measure of brain work, and the cerebral oxygen consumption rate, which is the precise measure of this work.

Experiments explore the restructuring of neuronal networks that follows when sensory activity is processed by healthy subjects or volunteers suffering from inborn or acquired lesions.

Albert Gjedde has through his career been taken different international academic positions in funding agencies, editorial- and advisory boards, council-, and committees and learned societies.
