SUMMARY:Lecture / Discussion:Professor Liliana Borcea\, the Peter Field Collegiate Professorship in Mathematics\, Inaugural Lecture
DESCRIPTION:Wave based imaging is an inverse problem for a wave equation or a system of equations with a wide range of applications in nondestructive testing of structures such as airplane wings\, ultrasound for medical diagnosis\, radar\, sonar\, geophysical exploration\, etc. It seeks to determine scattering structures in a medium\, modeled mathematically by a reflectivity function\, from data collected by sensors that probe the medium with signals and measure the resulting waves. Most imaging methods formulate the inverse problem as a least squares data fit optimization\, and assume a linear mapping between the unknown reflectivity and the data. The linearization\, known as the Born (single scattering) approximation is not accurate in strongly scattering media\, so the reconstruction of the reflectivity may be poor. I will describe a new inversion methodology that is based on a reduced order model approach. This borrows ideas from dynamical systems\, where the reduced order model is a projection of an operator\, called wave propagator\, which describes the propagation of the waves in the unknown medium. I will explain  how such a reduced order model can be constructed from measurements at the sensors and then I will show how it can be used for improving the existing inversion methodology.

SUMMARY:Lecture / Discussion:Sexual Citizens: A Landmark Study of Sex\, Power\, and Assault on Campus
DESCRIPTION:with respondents:\n-Abdul El-Sayed\, MD\, DPhil\, physician\, epidemiologist\, public health expert\, and progressive activist\n-Kamaria B. Porter\, Ph.D. Candidate\, Center for the Study of Higher & Postsecondary Education\; Research Assistant\, Department of Sociology\; University of Michigan\n\nThe fear of campus sexual assault has become an inextricable part of the college experience. But why is sexual assault such a common feature of college life? And what can be done to prevent it? Drawing on the Sexual Health Initiative to Foster Transformation (SHIFT) at Columbia University\, the most comprehensive study of sexual assault on a campus to date\, Jennifer S. Hirsch and Shamus Khan’s new book presents an entirely new framework that emphasizes sexual assault’s social roots\, transcending current debates about consent\, predators in a “hunting ground\,” and the dangers of hooking up.\n\nBased on years of research interviewing and observing college life―with students of different races\, genders\, sexual orientations\, and socioeconomic backgrounds―Hirsch and Khan’s study reveals the social ecosystem that makes sexual assault so predictable\, explaining how physical spaces\, alcohol\, peer groups\, and cultural norms influence young people’s experiences and interpretations of both sex and sexual assault. \n\nBook sales and signing will follow the discussion.\n\nCosponsors: Sexual Assault Prevention and Awareness Center (SAPAC)\, Departments of American Culture\, Sociology\, Women’s Studies\, School of Education\, and CEW+ Frances and Sydney Lewis Visiting Leaders Fund

SUMMARY:Workshop / Seminar:The Job Market Workshop Series (Zoom Meeting)
DESCRIPTION:The Job Market Series consists of 10 monthly workshops designed for psychology graduate students and postdocs who will soon enter the job market. All graduate students and postdocs are welcome to attend.\n\nThe series focuses primarily on the preparation of the application package for academic jobs\, including workshops targeted to each section of the application (e.g. cover letters\, research statements\, etc.).\n\nTwo annual workshops dedicated to the non-academic job market are also included. The timing of the workshops was selected to match an ideal timeline for students who will enter the academic job market in the fall of each year.
