My name is Samantha Sallie, and I am a 2nd year PhD student under the guidance of Dr. Valerie Voon in the Department of Psychiatry at the University of Cambridge. In addition to conducting research in psychological mechanisms of resilience, I previously trained in statistics and philosophy of science at the University of Pennsylvania and London School of Economics. Currently, I am focusing on detecting and modulating neural networks governing impulsivity and compulsivity in drug and alcohol addiction, via both invasive and non-invasive brain stimulation approaches. Relatedly, my most recent work aimed to understand how the stress of isolation affected alcohol consumption and problematic internet usage in the context of the COVID-19 pandemic. In the future, I hope to pair stimulation methods and cognitive tasks assessing mood-based impulsivity to inform more biologically-driven clinical treatments of addiction disorders.
