Professor Evans is the Dean of Agriculture, and Head of the School of
Agriculture and Food Science in University College Dublin. He is also Director
of the Reproductive Biology Research Cluster, a group of like-minded scientists
researching the factors impacting the establishment of pregnancy in cattle.
Professor Evans has attracted over 12 million euros of research funding, has
supervised over 30 graduate students, has published over 115 peer reviewed
papers and is the Co-Editor-in-Chief of the international journal Animal
Reproduction Science.
Professor Evans has a BSc in Animal Science from the Nottingham
University (UK), a PhD from the University of Saskatchewan (Canada) and a DSc
(Published work) from the National University of Ireland. Following a position
as a postdoctoral fellow in Cornell University (USA) he joined the academic
staff in University College Dublin, Ireland. His teaching is primarily in the
area of Animal Physiology with an emphasis on animal reproduction and
fertility.
Professor Evans has conducted research on a wide range of topics
focusing on reproduction and fertility in cattle and sheep. These areas include
the regulation of puberty, oestrus synchronisation, ovarian follicle
development, oocyte and embryo development, uterine health and function, and
management and physiological factors affecting fertility in cattle and sheep.
He is Director of the Reproductive Biology Research Cluster that is funded by a
multi-million Euro grant from Science Foundation Ireland (SFI) and a number of
industrial partners. The Cluster comprises over 60 scientists working on basic
and applied projects to address specific aspects of female infertility focusing
on events in the days immediately before and after fertilization. The overall
objective is to identify genes, proteins and other complex molecules, and their
expression patterns, in bovine ovarian follicles, oocytes, embryos, cervix and
uterus that are responsible for, or are markers of, infertility. Particular
focus is on those molecules that are responsible for failure of the initiation
and establishment of pregnancy in the days following fertilization.
