# Helena Groot

Helena Groot de Restrepo (Bogotá, 1947) is a Colombian microbiologist and geneticist.
She is a full professor in the Biological Sciences Department and the Medicine School at Universidad de los Andes. Since 1984 she has been the Human Genetics Laboratory director and her research has focused on cancer molecular epidemiology, genetic toxicology and environmental mutagenesis. She is one of the eight women members of the Colombian Academy of Sciences (ACCEFyN).

## Biography

Groot finished her school studies in 1965 in the Marymount school. She graduated from a B.Sc. in microbiology at Universidad de los Andes in 1970 and completed a M.Sc. in human genetics in 1984. Currently, Groot is a titular professor in the Biological Sciences department at Universidad de los Andes and she is the Human Genetics Laboratory director.

## Research field

The Human Genetics Laboratory has the highest classification (A1) in the Colombian Research Centers and Groups from the Ministry of Science, Technology and Innovation (Colciencias) since 2013.

### Genetic toxicology

In 1984, Groot replaced Maria Victoria Monsalve and became the Human Genetics Laboratory director. Initially she focused on citoxicity and citogenetics, determining the genetic effects of heavy metals, pesticides, solvents and particulates.

### Population genetics

Using mitocondrial and chromosomal DNA, the laboratory has aimed to understand the population dynamics of American colonizers. The lab has also made progress on the detection of population polymorphisms and its influence on DNA repair and cancer.

### Cell lines

Since 1998, the laboratory has established cell culture practices to understand DNA repair phenomena, citotoxicity and to explore cell matrix benefits in biomedical research.

### Epigenetics

The most recent research field in the laboratory is epigenetics effects in complex diseases, such as Von Willebrand disease, haemophilia A and B, diabetes, rheumatoid arthritis, dermatitis, Friedreich's ataxia, oculocutaneous albinism and Multiple sclerosis.
