Title: "Empirical Constraints on Theories of Planet Formation: Capitalizing on Diversity"
Abstract: Planetary bodies provide suitable environments for the emergence of life. Thus knowing their distribution as a function of mass, orbital radius, and bulk composition can help constrain the possible number of habitable worlds. Observations in the accessible regions of our Galaxy provide empirical constraints on planet populations. Yet extrapolation of these results to the rest of the observable Universe requires understanding the dependence of formation and evolution on a wide range of initial conditions. On the one hand, this process is simple: small bodies grow into larger ones through collisions (and sticking) of solid particles, or through local gravitational instabilities. On the other hand, the specific outcomes depend on a large number of complex properties requiring coupled understanding of dynamics, chemistry, and radiative transfer over several orders of magnitude in solid particle size, gas density and orbital radius.
I will first introduce some basic concepts of planet formation, with a focus on how they might depend on stellar mass. Then I will review current observational results (RV, micro-lensing, and direct imaging) that constrain these theories and outline a framework to quantify our ignorance. Finally, I will propose experiments (some underway with new IR instrumentation on 8-meter class telescopes, and others planned for future facilities) that aim to efficiently improve our understanding. One exciting prospect is to determine peak in the surface density distribution of gas giants (and the minimum of the companion mass ratio distribution) as a function of stellar mass suggesting current theories to a very stringent test.

Title: "The Measurement Challenges and Significance of Singly Charged Ions in the Heliosphere"
Abstract: A difficult to measure, but highly significant ion population in the Heliosphere is that of singly charged ions. The densities of these ions are often orders of magnitude below those of the solar wind, and their energies are insufficient for full characterization using present-day techniques. These ions can be from planetary, solar, and interstellar sources, and they contain information about the plasma and dust compositions of their origin. This overview will cover some of the significant science that has come out of singly charged ions, as well as the difficulties in observing them and some of the measurement techniques being investigated for future flight instruments.close

Title: "Mentoring Insights and Practices: Examining the Experiences of African-American STEM Mentors in Higher Education"
Abstract: National initiatives seek to tap into underrepresented populations to assist in meeting the demand to fulfill future scientific and technical jobs in the United States. In order to support and bring these national initiatives to fruition, steps must be taken to address existing obstacles. In the case of minority students, we must begin by examining ways to assist underrepresented minority (URM) STEM students persist in the face of obstacles and challenges, to graduate, and become available talent for future jobs. Mentoring can be a mechanism that aids in diversifying who participates and persists in STEM fields. Mentors provide emotional, psychosocial, and career support which can help protégés persist in their chosen STEM disciplines. Thus, mentoring can support the production of future engineers. Unfortunately, minimal research studies exist that examine the mentoring approaches, practices, and interactions that occur in URM mentoring relationships. In this seminar, Dr. Joi Mondisa will discuss findings from her research that examines the individual experiences of exemplar African-American STEM mentors and their mentoring practices with their African-American protégés. Using qualitative methods, this research reveals insights about mentoring experiences that can inform educational practices and diversity initiatives. In addition, this research offers a language for talking about these experiences which are not captured by existing literature.
Biography: Joi Mondisa is an Assistant Professor in the Industrial & Operations Engineering Department at the University of Michigan. In her research, Dr. Mondisa focuses on examining mentoring approaches, relationships, and intervention programs. Other areas of study include designing and assessing learning experiences and outcomes. She earned a B.S. in General Engineering at the University of Illinois at Urbana-Champaign, an M.B.A. at Governors State University, and an M.S. in Industrial Engineering and a Ph.D. in Engineering Education from Purdue University. Prior to earning her graduate engineering credentials, Dr. Mondisa worked in industry for ten years in the areas of manufacturing, operations, technical sales, and publishing.close
