All levels of Psychology PhD students are welcome and food will be provided!\u00a0Exponent investigates human factors\u00a0to make products safer, improve work environments, investigate accidents, and inform product design, by examining what drives human decisions, behaviors, and actions. David has spent the last 22+ years applying his expertise in cognitive psychology to solving real-world problems by answering challenging questions about the capabilities and limitations of human perception and performance. We hope to see you there!\u00a0",

        "description":"Derived functors play a central role in commutative algebra, organizing algebraic computations through exact sequences and homological methods. This talk begins with a brief conceptual revisit of derived functors in homological algebra, and then examines K\u00e4hler differentials of commutative rings as a motivating example for why we want derived functors beyond abelian categories. \n\nTo address this problem, we trace Dan Quillen\u2019s insight that homotopical methods provide an ideal framework for defining derived functors in nonabelian settings. Along the way, we encounter his definition of model categories, which have since become central tools in modern homotopy theory. From this perspective, the cotangent complex arises as a derived replacement for K\u00e4hler differentials. We will outline the construction of the cotangent complex and discuss some of its powerful applications to deformation theory. Time permitting, I will say something about how the homotopical viewpoint reconciles with homological algebra.",
