Dr. Niels Briger Ramsing (Embryologist-Denmark)
Summary
Niels Birger Ramsing is Director for Strategic Product Development at Vitrolife A/S in Aarhus,
Denmark. He was the Chief Scientific Officer of Unisense FertiliTech A/S prior to the Vitrolife
acquisition and has a M.Sc. In Biostructural Chemistry and a Ph.D. in Microbial Ecology by the
University of Aarhus, DK. He is the inventor of the EmbryoScope and project leader for the
development of the EmbryoScope+.
Dr. Niels Birger Ramsing is currently the director for strategic product development in Vitrolife A/S.
He joined Unisense FertiliTech A/S, Denmark, as the Chief Scientific Officer in 2004, which was
subsequently acquired by Vitrolife AB in 2014. Prior to his work in the field of IVF he received his
M.Sc. in Biostructural Chemistry as well as his Ph.D. in Microbial Ecology from the University of
Aarhus, DK. Dr. Ramsing’s research expertise and interests span a diverse range of scientific
disciplines: development of novel diagnostic tools and technologies, DNA chip technology using high
affinity nucleotide analogues, development of microfluidic chip technology, quantitative molecular
biology, microsensor technology. Relevant to the EmbryoScope Time-lapse system technology from Unisense
FertiliTech, Dr. Ramsing has expertise in mathematical modelling and image analysis, as well as embryo
selection knowledge pertaining to assisted reproduction applications. The breadth of his experience has
been pivotal to the development of the EmbryoScope® Time-lapse imaging system.
During the early development of the EmbryoScope system, Dr. Ramsing worked closely with key opinion
leaders in the ART field. Together with ART innovators like Dr. Lynette Scott at Fertility Centers of
New England and Dr. Marcos Meseguer Escrivá from IVI, the system was elevated from a non-invasive and
sensitive micosensor system that measures respiration rates of the developing embryo to a cutting-edge
incubation platform with time-lapse imaging and assessment of morphokinetic milestones to aid in
selection of the best embryos for transfer.
Dr. Ramsing has been a guest speaker at more than forty international conferences and laboratories
across the globe. His publications exceed more than sixty articles accepted in international peer
reviewed journals. Dr. Ramsing also has ten patent application families filed since
2002.
