Emma Caroline Teeling^[1] MRIA is an Irish zoologist, geneticist and genomicist, who specialises in the phylogenetics and genomics of bats. Her work includes understanding of the bat genome and study of how insights from other mammals such as bats might contribute to better understanding and management of ageing and a number of conditions, including deafness and blindness, in humans. She is the co-founder of the Bat1K project to map the genomes of all species of bat. She is also concerned with understanding of the places of bats in the environment and how to conserve their ecosystem.

Teeling is a full professor at University College Dublin, where she has founded two scientific centres: the Laboratory of Molecular Evolution and Mammalian Phylogenetics (also known as the "BatLab"), and the Dublin part of the Centre for Irish Bat Research.^[2] Teeling is widely cited in her areas of study and is an elected member of Ireland's national academy, the Royal Irish Academy.^[3]

Emma Teeling was born to John and Deirdre Teeling. Her father is an academic, and serial entrepreneur in the mining, Irish whiskey and other sectors, while her mother is an academic in the area of education; they married in 1971. She has two younger brothers, Jack and Stephen, and she and her siblings grew up in Clontarf, where her father has his head office for multiple companies,^[4] and with her mother working in a school in nearby Coolock,^[5] another northern suburb of Dublin.^[6] She played Dublin-level camogie for Fairview.^[7] She attended Holy Faith Secondary School, Clontarf,^[8] and was the author of one of a set of short articles about late 1980s Moscow for a Soviet Supplement in the Irish Independent, after a school trip to the USSR.^[9]

From 1991 to 1995, Teeling took a B.Sc. in Zoology at University College Dublin (UCD), which included study of deer in Dublin's Phoenix Park.^[8] She further studied at the University of Edinburgh, for an M.Sc. in Animal Behaviour and Welfare, from 1995, including working with swift foxes^[8] at the Cochrane Ecological Institute in Canada.^[10] She then saw an advertisement for PhD studies relating to bats,^[8] and pursued this from 1997 at Queen's University, Belfast and the University of California at Riverside.^[11] She filed her thesis on A molecular perspective on chiropteran systematics in December 2001, and received her PhD in molecular phylogenetics from Queen's.^[1]

Teeling worked as a postdoctoral research fellow from 2002 to 2004 at the US National Cancer Institute. In 2005, she returned to Ireland to take a role as lecturer in Evolution and Genetics in the School of Biology and Environmental Science at UCD, securing tenure in 2006. She founded the Laboratory of Molecular Evolution and Mammalian Phylogenetics (known as the "BatLab" even in official materials)^[12][13] at UCD in 2005, and the Centre for Irish Bat Research at UCD in 2008; she remains one of the four Principal Investigators of this cross-border project, and its director.^[14] The Laboratory of Molecular Evolution and Mammalian Phylogenetics conducts a large amount of field work in Brittany, working with a conservation organisation, Bretagne Vivante.^[15] Teeling is also concerned with understanding of bat populations and their broader ecosystems, and bat conservation.^[2]

Teeling was promoted to associate professor (in Evolution and Genetics) in 2012,^[2] and later to full professor. She is also Head of Zoology.^[10] In addition to her research work, she teaches or coordinates a number of courses, and supervises PhD studies.^[16] As of 2020, she is also Deputy Director of UCD's Earth Institute.^[17]

Teeling has written and co-written many articles, papers and chapters, some of which are widely cited. Extant are more than 100 documents, with a citation level, per Scopus, of 6424 applications across 4751 citing documents, and a h-index of 31 ("very good").^[33][2] Papers which Teeling has authored or to which she has contributed include:^[2]

Teeling is a member of the Society for Molecular Biology and Evolution and was a member of the society's 2012 Annual Meeting Committee, which managed the event in Dublin, Ireland^[48] and later a member of the society's governing council.^[49] She is also on the editorial board of one of the society's two journals, the Journal of Molecular Biology and Evolution.^[50]

She is also a member of the editorial board of Oxford University Press's open-access journal Giga Science.^[51]

Teeling was appointed to the board of the Irish Research Council.^[52] She was elected as one of the professorial members of the Governing Authority of UCD in 2019, for a five-year term.^[53]

Teeling has presented a TEDx talk, on the genome of bats, which has been viewed, as of 16 June 2022, more than 565,000 times.^[54] University College Dublin has also uploaded one of her lectures, 'Bats: secrets of extended lifespan', to YouTube.^[55] She has been interviewed and featured on radio - on one occasion in episode 2 of a series, 'Bright Sparks', which also interviewed her astronomer husband, in episode 8, about his work - ^[56][57][58] and television. On one occasion programme-makers accompanied her team when it was locating bats in old churches in Brittany.^[59] Following the release of the first six bat genomes by the Bat1K consortium, Teeling was interviewed by the BBC and commented on how bats' unique immune systems may help them defend against viruses, including COVID.^[60]

Teeling is married to astrophysicist Peter Gallagher, a senior professor at the Dublin Institute for Advanced Studies and adjunct professor at Trinity College Dublin, at the latter of which he worked for many years. They both came from Clontarf in Dublin but only met in first year Science in UCD. They lived near Washington D.C. for part of their time in the US during advanced studies, before moving back to Ireland together when Teeling received a job offer from UCD.^[61] They have two sons.^[27][62] Teeling invested in the first round of funding for her brothers' whiskey distillery company, the Teeling Whiskey Company, operating the Teeling Distillery, the first new distillery in Dublin for 125 years.^[63][64]
