Curriculum Vitae et Studiorum

Olga Rickards was one of the first scientist in Italy to apply Molecular Anthropology to the reconstruction of the origin and history of human populations, traditionally studied through palaeontology and archaeology. Since the early seventies, her research group has investigated human genetic variability first at protein and afterwards at DNA level. These data were used to explore the evolutionary history of human populations living in various geographical areas, providing a quantitative and temporal framework that was unavailable from other types of evidence. Since 1990’s her research has focused on the characterization of ancient genetic material from prehistoric peoples of Italy, North Africa and South America and the comparison with sequence data from modern populations.


– She achieved her Ph.D. in Natural Sciences at Sapienza – Università di Roma (1978 in Anthropology).
– She achieved her Ph.D. in Biological Sciences at Sapienza – Università di Roma (1981 in Molecular Anthropology).
– She became in 1984 Assistant Professor of Molecular Anthropology at Tor Vergata – Università di Roma.
– She became in 2000 Full (Ordinarius) Professor of Molecular Anthropology at Tor Vergata – Università di Roma.

At Tor Vergata University she has served as:
– Head of the “Departmental Centre of Molecular Anthropology for ancient DNA studies” (since 1996; Department of Biology).
– President of the First and Second level Degree Courses in Biology (2005-2011).
– Coordinator of the Macroarea of MFN Sciences (since 2012).
– Vice Director of the Department of Biology (since 2012).
– Member of the PhD Committee in Evolutionary Biology and Ecology (since 1993).
– Member of the Senato Accademico Integrato (1993-1998).

Long/short term research appointments
– NATO fellow, Department of Genetics and Molecular Biology, University of Hawaii (1998-1999; 1991-1992; 1994);

Research Activity

The research activity of Olga Rickards is characterized by a methodology and perspective involving both a strong engagement as a field anthropologist, with a personal and direct participation in sample collections, and a remarkable interdisciplinary approach, dealing with archaeology, geology, ecology, physical and molecular anthropology, botany, zoology and biochemistry, to the reconstruction of human populations history and evolution as evinced in her publications (more than 250).

The main research expeditions Olga Rickards participated to were carried out:

  1. at Tahala and El-Awinat villages (Libyan Sahara) in 2004, as part of the Italian-Libyan Archaeological Mission in the Acacus and Messak of the Sapienza University of Rome and the Department of Antiquities, Tripoli, directed by Prof. Savino di Lernia and the late Ebrahim Azzebi, and aimed to clarify the genetic composition and origin of the extant Libyan Tuaregs and their possible relationships with the Garamantes people;
  2. and at Olduvai Gorge, near the Great Rift Valley in northern Tanzania in 2011, as cohordinator and supervisor of the field-workshop organized by the University of Perugia in the frame of the first edition of the Palaeoantropology school held in Perugia on 14-18 February 2011.

In 2009 she was awarded the Accademia Nazionale dei Lincei International Prize “Fabio Frassetto” for anthropology for her scientific research in the field of molecular anthropology with special mention to ancient DNA studies.

Research Interests: Human evolution, mtDNA and nuclear polymorphisms, ancient DNA, stable isotope analysis for reconstructing genetic history, palaeodiet and migrations of ancient populations.
