Alexa is a second year Experimental Psychology PhD student in the Lifespan Decision-Making Laboratory, under the supervision of Dr. Ben Eppinger (CRDH). Broadly, she is interested in modeling developmental changes in learning and decision-making strategies in order to better understand how school-aged children learn, and how we can support learning in and outside of the classroom. Specifically, she is examining how the use of model-based, model-free and other intermediate decision strategies change across the lifespan. To do so, she uses methods such as electroencephalogram (EEG) and computational modeling.
Ariel A. Batallán burrowes
Ariel A. Batallán Burrowes is currently a PhD candidate working under the guidance of Dr. C. Andrew Chapman as a member of the Center for the Study Behavioral Neurobiology (CSBN). Ariel completed his undergraduate studies at Colby College in Waterville, Maine and received a BA in Psychology with a focus in Neuroscience. During his time there, Ariel was a member of the Behavioral Neuroscience Lab for five years, under the leadership of Dr. Melissa Glenn. There he assisted with research investigating behaviors and neurobiological mechanisms of learning and memory associated with dietary manipulations, pharmacological and genetic models of schizophrenia, and sex differences. Here at Concordia, Ariel continues to focus on sex difference research, exploring the modulatory role of ovarian hormones on neuronal function within the entorhinal cortex, a region important for sensory information, using electrophysiological techniques.
Sean is a Master's student in Ben Eppinger's Lifespan Decision-Making Lab (CRDH). His main research interests are cognitive effort and decision-making. In other words, he wants to try to answer the question: how does how hard we think affect how we make decisions? He was excited about this journal when I first heard of it, because too often does good science go unheard because it's bogged down jargon.
Rachel is a second year PhD Student in the Clinical Psychology program and am completing my research under the supervision of Dr. Karen Li in the Cognitive Aging Laboratory. She is a member of The Centre for Research in Human Development (CRDH). Her research focuses on how to optimize older adult’s cognitive and physical functioning through exercise and cognitive training. She is particularly interested in using functional near infrared spectroscopy to study brain activity when older adults walk while completing a secondary cognitive task (termed dual-tasking), and how this changes following training.
Heather is a PhD candidate in Dr. Wrosch's Personality, Aging, & Health Lab (CRDH). Her research focuses on pathways to successful aging. She studies the impact of stress on health and how personality factors (e.g., self-compassion) can help protect older adults from stress-related health declines.
Broadly speaking, Sandra’s research looks at understanding the nature of, and mechanisms behind different symptoms in obsessive-compulsive disorder (OCD) and other anxiety disorders, as well as identifying possible treatment targets for these disorders. More specifically, her research topic is looking at the specific symptom of mental contamination (which is seen in OCD and in posttraumatic stress disorder), which is feelings of internal dirtiness people experience after a perceived violation (e.g., sexual assault). Her thesis is looking at how a person's perception of responsibility for a sexual violation might impact the severity of feelings of mental contamination, and subsequent washing behaviour.
Marie-Pier is a second year Master’s Student doing research under the supervision of Dr. Dale Stack and Dr. Lisa Serbin as part of the Infant and Child Studies Laboratory. She is a member of The Centre for Research in Human Development (CRDH). Her research pertains to the development of antisocial behaviors from infancy to late adolescence. Particular foci of her work are longitudinal prospective designs that allow for the investigation of the moderating, mediating, and transactional processes involved in the persistence or transience of antisocial behaviors.
Alexandra is a first year Master’s student in Dr. Iordanova’s Learning and Memory lab. She completed my Behavioral Neuroscience B.sc at Concordia. During that time, she became invested in Pavlovian learning. Cues that predict biologically relevant events can hijack behavior. For example, drug-related cues trigger cravings in dependent individuals. But how does the brain process this information? Her project focuses on the role of VTA dopamine. Her lab uses optogenetics to stimulate dopamine neurons. Namely, in locking and second-order conditioning. Their recent findings suggest dopamine serves as a prediction error signal. The theory that it only encodes changes in value may be too narrow. Her goal is to discover methods of rescuing hijacked behavior. One day she hope to use what she learned to help drug-dependent populations.
Milan has a Master’s degree in psychology from Wilfrid Laurier University and is currently a doctoral candidate at the Center for Studies in Behavioral Neurobiology at Concordia. He studies substance use disorders and is particularly interested in the neural systems that control how cues in the environment trigger relapse.
Coordinator of public and social affairs
Cassandra recently completed by Undergraduate degree at Concordia University. Her research interests include how the ability to engage in cognitive control changes across the lifespan. More specifically, she is interested in investigating the developmental and individual differences in effort-reward trade-offs. She would like to study these basic cognitive mechanisms on a neuobiological and computational level.
