Lara Cassidy - Speaker Profile


Presentation: A Genomic Compendium of an Island: Documenting Continuity and Change across Irish Human Prehistory

What will be discussed?
Lara will discuss the findings of her recently completed thesis which assessed the genomes of 93 ancient skeletal remains across the island of Ireland. This analysis provides the most comprehensive analysis yet of prehistorical migrations into Ireland and how the arrival of these waves of new populations shaped who the people of Ireland are today.

Background:

Lara developed an interest in biology and evolution from a young age through popular science books left lying around the house by her father. She went on to complete an undergraduate degree in Human Genetics at the Smurfit Institute of Genetics, Trinity College Dublin and finished with first-class honours.

She was subsequently awarded a postgraduate scholarship by the Irish Research Council to undertake a PhD in Palaeogenomics the Bradley Lab at the same institute. The main focus of this project was the sequencing of ancient human genomes from all periods of the island's prehistory to study past demography. 

The first publication of this work (Cassidy et al. 2016) presented a new demographic scaffold for the island, proposing that at least three ancestrally distinct Irish populations have existed on the island, whose inhabitation corresponds closely to the Mesolithic, Neolithic and Chalcolithic/Early Bronze Age eras. Large scale migrations into the island are implied during the transitionary periods carrying with them ancestry ultimately derived from Anatolia and later the Russian steppe. 

Lara completed her PhD last year and is now continuing on with her work on Irish human ancient genomics as a postdoctoral researcher in the Bradley lab.

Talk Title:  The Power of Mitochondrial DNA Affiliations I am one of the founders of SSGG, the Swedish Society of Genetic Genealogy. Also a member of ISOGG. What do you do as a Day Job? I’m a professional Genetic Genealogist at the company DNA Academy, providing training, presentations and consultancy for genealogists. I am also an author, having written a handbook in genetic genealogy and a popular science book on the peopling of Sweden, spanning the past 11,000 years. I am a regular contributor to the Swedish genealogy magazines. Before I did go 100% into genetic genealogy, I worked many years as a chemical management consultant. What do you do as a Night Job? When I’m not deep into mutations, DNA segments and church records, I have a family of four, 10 chickens and a farm house built in 1799 to care for. How did you get into genealogy? I have always been interested in local history and I love solving mysteries, so I got hooked on genealogy 30 years ago. My special interest is to...

Talk Title: The genetic identification of the 1916 Cork Rebel, Thomas Kent Affiliations: University College Dublin – School of Biology and Environmental Science/Earth Institute Qualifications: PhD in Population Genetics (Swedish University of Agricultural Sciences, Sweden) What do you do as a Day Job? Lecturer at UCD What do you do as a Night Job? Research, primarily focused on aquatic organisms including fishes, shellfish and hydrothermal vent and methane seep fauna. My research interests are in conservation, ecological and population genetics, as well as evolutionary biology. I employ genetic tools at population and individual levels to study genetic questions (gene flow, genetic drift, effective population size and selection) and to couple genetics with behaviors (kin-biased behaviours, reproductive success, mate choice, migratory behavior and life-history). I am also interested in conservation genetics, functional genomics and studies that combine population genetics, beh...

How do you feel about your DNA being used by the police? - the results of a survey

Background In April 2018, US police finally identified a murder victim (known as " Buckskin Girl ") whose identity had remained a mystery for 37 years. Despite everything that they threw at the case, Forensic Science could not come up with the answer. But Genetic Genealogy did, and in doing so, made history. The Buckskin Girl case was solved in 4 hours once the kit had been processed by Gedmatch The excitement generated by the case did not have a chance to die down because two weeks later, the prime suspect in the  Golden State Killer case  was arrested, causing a media storm. Once again, genetic genealogy techniques had helped identify the most likely candidates for the killer, and (using routine police work) officers had followed these leads and gathered the evidence necessary to bring charges against a single individual. Since then  over 11 people  have been arrested and charged with rape or murder, thanks to the application of the new technique by Law Enforcement...
