Eliana Maria Beluzzo Dessen

Dr. Dessen is a retired assistant professor in the Department of Genetics and Evolutionary Biology, Institute of Biosciences (IBUSP). She graduated as a Bachelor and Licentiate in Biology, IBUSP, in 1970; She obtained her MSc degree (1973) and the PhD degree (1978) at the same institution. She carried out a post-doc program in chromosome physiology at the Max –Planck Institut für Biologie, Tübigen, Germany, from 1981 to 1983, and later in molecular biology at the Zentrum für Molekulare Biologie Universität Heidelberg, Germany, during 1989.
She has been the Coordinator of the program for Education dissemination at the Human Genome Research Centre ( CEPID – CEGH) since 2005. She is also a member of Conselho Regional de Biologia – CRBio-1. In the past she taught molecular biology, cell biology, genetics and cytogenetics and currently teaches molecular biology in the “licenciate” course.

After retiring in 1997, she dedicated herself to education and dissemination of genetic information and has coordinated many didatical activities related to genetics, for instance: “Genética na Praça” carried out annually at the National Genetics Congress; the production of instruction materials; curatorship of scientific exhibitions; keeping public school teachers up to date with genetic training programs; development of new scientific projects for use in secondary schools.


Research Profile
Dr. Dessen started her scientific trajectory studying the effects of the hormone ecdisone in nucleoli and in DNA and RNA puffs in the polythene chromosomes of Sciarids. She also investigated aspects of dosage compensation in the X chromosome of Drosophila males, characterized genomic regions of Drosophila mutant strains and was mainly dedicated to the molecular study of site-specific genomic amplification in polythene chromosomes of Trichosia pubescens. She also worked on the characterization of several populations of Anopheles cruzii in malarial endemic regions in southeastern Brazil.

Education/information dissemination projects
2002 to the present: Coordination of “Genética na Praça” – http://www.sbg.org– education activity presented annually during the National Congress of Genetics. “Genética na Praça” is an activity focusing on Genetic education: it aims to address fundamental questions to stimulate curiosity, to encourage the search for knowledge in young people and to provide a basis for the discussion of ethics and social issues related to science.

2004-2005 – Coordination of the project Micro&Gene – http://www.ib.usp.br/microgene, which focused on teaching genetics and microbiology. The aim was to develop diversified teaching methods, to stimulate curiosity and the search of knowledge, in order to improve learning ability in a lucid way.

2005 to the present– Coordination of projects on science dissemination to high schools and the general public in the context of the human genome project and in conjunction with research themes at the Human Genome Research Centre (CEPID – CEGH) at USP:
