The monarch migratory syndrome is complex, integrating behavior, morphology, and physiology in an environmentally sensitive manner. Underlying this syndrome is an expansive genetic suite encompassing over 500 genes, as well as a significant capacity for seasonally-sensitive phenotypic plasticity. The evolutionary histories of this genetic suite and capacity for seasonal plasticity remain largely unknown beyond within-monarch assessments.\r\nMonarch migration is an emerging model for testing broader hypotheses about the evolution of animal migration, complex traits, and the role of plasticity in adaptive evolution. A clearer understanding of how this spectacular phenomenon has emerged within just the past 20,000 years is necessary to better contextualize evolutionary inferences drawn from this model. My dissertation research will focus on characterizing patterns of seasonal plasticity as well as migratory genetic and phenotypic variation within the butterfly genus Danaus.

Yet current and near-future surveys of the universe will yield spectra for millions of galaxies and imaging for billions. I will discuss the tactics employed to speed up these codes, ranging from neural net emulators of key physics (photoionization modeling; stellar spectra) to efficient gradient enhanced GPU-accelerated high-dimensional sampling to rapid simulation-based inference. These yield speed-ups of somewhere between 100x and 100,000x, with unavoidable trade-offs in flexibility and accuracy. I will discuss applications of these techniques to model modern astronomical data, including both industrial-scale modeling of galaxy SEDs and newly-possible directions such as spatially resolved galaxy modeling.

There are individual attitudes (e.g., preference for burritos) that vary in strength (e.g., central to the self), resistance to change (e.g., unwavering in the face of dietary information), and their relationship with relevant behaviors (e.g., purchasing of burritos). This approach misses a key property of attitudes: Attitudes are interdependent. \r\n\r\nIn this talk, Brandt focuses on recent research from my lab that studies how attitudes are dependent on other attitudes, identities, and values within a political belief system. He presents the findings that (1) central attitudes of a political belief systems are stronger, being more stable overtime and more resistant to change and (2) that attitudes become moralized when they are connected with other moralized attitudes in the belief system. In combination, these findings suggest that the interdependence of attitudes matters for attitude change and moralization. \r\n\r\nThe goal of Mark Brandt's research is to understand the causes and consequences of political, religious, and moral beliefs that can ultimately be leveraged to reduce conflict and promote a more fair, just, and free society. He studies ideological and moral beliefs \u2013 such as political ideology, racism, religious fundamentalism, and moral conviction \u2013 and how they structure attitudes and behaviors, how they become moralized, and why people adopt them in the first place.\r\n\r\nDavid Dunning, organizer of the Katz-Newcomb speaker series in Psychology and an associate of the Research Center for Group Dynamics, hosts.
