What does it mean when something like addiction or depression is genetically influenced? Are people who are at risk destined to develop problems? Psycologist Danielle Dick explores how our genes and our environments come together across the lifespan to create multiple pathways that can influence addiction.
#addiction #mentalhealth #behavior #genetics
This talk was given at a local TEDx event, produced independently of the TED Conferences. It was filmed and edited by Tijo Media at the Carpenter Theatre at Dominion Arts Center in Richmond, VA.
Dr. Danielle Dick is a Professor in Psychology, African American Studies, and Human and Molecular Genetics at Virginia Commonwealth University. Her research examines genetic contributions to substance use and mental health outcomes, and how the importance of genetic predispositions changes in different environments. She has received millions of dollars of grant funding from the National Institutes of Health and won numerous national and international awards for her research. She founded and directs the College Behavioral and Emotional Health Institute and runs a study called Spit for Science with nearly 10,000 college students taking part.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Dr Niamh O’Sullivan is a University College Dublin (UCD) lecturer in neuroscience and genetics in the UCD School of Biomolecular and Biomedical Science, UCD Conway Institute, whose TEDxUCD 2014 talk is entitled ‘Do My Genes Define Me?’
News reports and articles frequently appear declaring that scientists have discovered a new gene which ’causes’ various diseases or traits including heart disease, cancer or IQ levels… but what is the reality of these claims and how do they affect us in our day-to-day lives?
In her TEDxUCD talk Dr Niamh O’Sullivan discusses the current state of our understanding of genetic variations and, as someone who knows quite a lot about her own genetic code, looks at how her genes affect her physical appearance, her personality and her health and asks whether it can be argued that who she is, is determined by her genetic code.
Dr Niamh O’Sullivan is a lecturer in neuroscience and genetics in UCD’s School of Biomolecular and Biomedical Science in the UCD Conway Institute. She is also a principal investigator studying the mechanisms underpinning human neurodegenerative disorders such as motor neuron disease and Alzheimer’s disease. Her laboratory makes use of the experimental model organism the fruit fly (Drosophila melanogaster) to better understand the functions of genes linked to the human diseases.
Niamh graduated with a BA (Genetics) from Trinity College Dublin before moving to UCD where she undertook a PhD investigating the genetic events that occur during memory formation. She continued to work on this successful project before receiving a Marie Curie Fellowship to study neurodegeneration using the fruit fly at the University of Cambridge. Her work at Cambridge suggested a new explanation as to why neurons are dying in some forms of human disease.
Niamh received a Junior Research Fellowship from Imperial College London to continue her research before being appointed to her academic position in UCD last year.
Niamh is passionate about science and is keen to raise the level of discussion on all areas of discovery.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
