Ulrik Braüner Nielsen is a Senior Researcher at the Department of Geosciences and Natural Resource Management, University of Copenhagen. His research focuses on forest genetics, particularly related to Christmas tree production and Abies species. Dr. Nielsen's research interests include: Forest Genetics and Tree Breeding Christmas Tree and Greenery Production Tree-Insect and Tree-Fungus Interactions Genus Abies Species for Timber and Christmas Tree Production Biomass Production His recent work has centered on genetic variation in Nordmann fir (Abies nordmanniana), somatic embryogenesis, SNP genotyping, and disease resistance. Dr. Nielsen has published extensively on conifer genetics with 146 research outputs, demonstrating a consistent research trajectory focused on improving Christmas tree production through genetic research. His work bridges molecular genetics with practical forestry applications, particularly in the areas of propagation techniques and genetic improvement of conifer species. Dr. Nielsen serves as a member of Plantedirektoratet (Danish Forest and Nature Agency) and has been involved with this organization from 2011-2012, contributing his expertise to national forestry policy and management decisions. Outside of his professional work, Dr. Nielsen maintains a personal connection to his research area as a hobby farmer with his own production of Christmas trees and greenery, as well as seeds, which likely provides practical insights that inform his academic research.
