When Enough Isn’t Good Enough: The Role of the Hippocampus in Reward Learning
Professor André White first explored the neuroscience behind drug-addiction as an undergraduate student researcher. At Dickinson College, he explored the role specific drug receptors played in methamphetamine-induced behaviors in mice. This work led to his first peer-reviewed publication and a lasting passion for behavioral neuroscience research. He has not strayed far from his early work, as he currently studies the molecular mechanisms that underlie cocaine-associated behaviors. White’s work investigates the complex environmental and genetic factors that modulate addictive behaviors in mice. He seeks to use his research to inform therapeutic and policy approaches to combating addiction.

“Forming Impressions of Others in the Era of Fake News, Social Media, and Gossip”

Prof. Jeremy Cone received his Ph.D in Social Psychology from Cornell University in 2012. He spent a year as a visiting assistant professor at Williams in 2012-201, followed by a post-doc in the Human Cooperation Lab at Yale University from 2013-2015. He rejoined the faculty at Williams as an assistant professor in 2015. His research focuses on understanding the nature and operation of implicit processes, including especially implicit attitude change.
Prof. Jeremy Cone’s lab studies the science of first impressions — how quickly you develop an opinion about someone and how easily that opinion can be changed as you learn new things about them. We study, in particular, a type of impression that we call “implicit” — ones that are spontaneous, unintentional, and they happen really, really fast (literally the blink of an eye). Importantly, they’re often quite different from how you consciously feel about someone — what you say when I ask you whether you like or dislike someone. You can consciously like someone and yet have a strong implicit negative reaction to them, and you can also consciously dislike someone and yet still feel implicitly positively towards them. We try to understand where those automatic gut-level reactions come from, what kinds of information can shape them after they’ve become well-established, and how they differ from conscious impressions.

Future Foods: How Modern Science is Transforming the Way We Eat
We are in the midst of an unprecedented era of rapid scientific and technological advances that are transforming the way our foods are produced and consumed. Professor Julian McClements will be discussing how food architecture is being used to construct healthier, tastier, and more sustainable foods. Functional foods are being created to combat chronic diseases such as obesity, cancer, diabetes, stroke, and heart disease.
These foods are fortified with nutraceuticals or probiotics to improve our mood, performance, and health. The dissimulation of foods inside our guts and assimilation by our bodies is being controlled to increase their healthiness. Precision nutrition is being used to tailor diets to person’s unique genetic profile, microbiome, and metabolism. Gene editing, nanotechnology, and artificial intelligence are being used to address challenges such as feeding the growing global population, reducing greenhouse gas emissions, and improving sustainability. This presentation highlights some of the interesting scientific advances being made in the food area and the role of structural design to create a better food future.
