Helena Josefina Kjöllerström

Main Research Interests

My main research interests are: cytogenetics analysis, combined with the genetics of reproduction and fertility as well as Y-chromosome fertility markers in the horse.

I am mainly interested in the study of horses, namely the Sorraia breed from Portugal.

 

Academic Qualifications

2005 - Degree in Biology (University of Lisbon)
