In this role, he is the member of the academic affairs leadership team who is in charge of all aspects of Oxy's curriculum. His primary responsibility is direction of the general education program and he has several other academic initiatives reporting to him, such as undergraduate research, Oxy's writing program, community-based learning, Oxy Arts and multiple interdisciplinary centers for the research of and outreach to Los Angeles. He has more than four years of service in the federal government as an employee of the National Science Foundation (NSF) from 2011-2013 and 2016-2018. There he was Lead Program Director of the NSF Scholarships for Science, Technology, Engineering and Mathematics (S-STEM) program housed in the Division of Undergraduate Education and a permanent program director responsible for undergraduate mathematics education. He has been on the Oxy faculty since 1994, serving as chair of the Oxy mathematics department twice (2005-2010, 2015-2016) and achieving the rank of Full Professor in 2014 after beginning his academic career at Oxy as a Minority Postdoctoral Scholar-in-Residence. Ron holds mathematics degrees (Ph.D., M.Sc. and B.Sc.) from Rensselaer Polytechnic Institute in Troy, New York. He has published peer-reviewed articles in an eclectic collection of peer-reviewed journals such as Data, Notices of the American Mathematical Society, Numerical Methods for Partial Differential Equations, IMA Journal of Management Mathematics, Works and Days and the Albany Law Review. His areas of research interest include mathematical modeling, applied mathematics, numerical analysis (specifically nonstandard finite-difference approximations of ordinary and partial differential equations), mathematics education, data science and the scholarship of teaching and learning. He is a passionate advocate for broadening the participation of underrepresented individuals in mathematics and other STEM disciplines and a strong believer in the importance of liberal arts education in the creation and maintenance of an equitable, just and thriving civil society.

Title: Different Differences, Video

Abstract: This talk is centered around different examples of the word "difference." First, I will summarize some of my work in the area of non-standard finite differences, which are numerical techniques used to generate approximate solutions of differential equations. Second, I will discuss how my differences from the typical mathematician has (perhaps) caused me to follow a different academic trajectory than one would expect. Lastly, I will present some comments on how the mathematics community treats "difference" and provide suggestions for how the future for other different mathematicians can be different from the past.

Emily Riehl (Johns Hopkins University)

Biography: Dr. Emily Riehl (she/her/hers) is an associate professor of mathematics at Johns Hopkins University, working on higher category theory, abstract homotopy theory, and homotopy type theory. She has published over twenty papers and written two books: Categorical Homotopy Theory (Cambridge 2014) and Category Theory in Context (Dover 2016), both of which are freely available online. She has been awarded an NSF grant and a CAREER award to support her work and has been recognized for excellence in teaching at both Johns Hopkins and at Harvard. A research monograph co-authored with Dominic Verity that reimagines the foundations of infinite-dimensional category theory, Elements of ∞-Category Theory, will appear sometime in 2021. In addition to her research, Dr. Riehl is active in promoting access to the world of mathematics. She has given interviews for the Association for Women in Mathematics, the radio program Science Friday, and the podcast My Favorite Theorem, and has been featured in the Girls' Angle Bulletin. She has given countless talks and lectures, including at the Women in Topology workshop at MSRI and the Women in Math and Statistics Conference hosted by Gender Inclusivity in Mathematics at Harvard. She is also a co-founder of Spectra: the Association for LGBT Mathematicians and has presented on mathematical proof and queer epistemology in the Women, Gender, and Sexuality Graduate Colloquium and Lecture Series at Johns Hopkins. She has also conducted an interview of fellow-Spectra co-founder Mike Hill On Performing Queerness in Mathematics for a guest post of the inclusion/exclusion blog of the American Mathematical Society.

Title: Contractibility as uniqueness, Video

Abstract: What does it mean for something to exist uniquely? Classically, to say that a set A has a unique element means that there is an element x of A and any other element y of A equals x. When this assertion is applied to a space A, instead of a mere set, and interpreted in a continuous fashion, it encodes the statement that the space A is contractible. This talk will explore this notion of contractibility as uniqueness and its role in generalizing from ordinary categories to infinite-dimensional categories.

Juliette Bruce (University of California, Berkeley / MSRI)

: Juliette Bruce is a National Science Foundation (NSF) Postdoctoral Research Fellow in the Department of Mathematics at the University of California, Berkeley, and Postdoctoral Fellow at the Mathematical Sciences Research Institute (MSRI) in Berkeley, CA.

Title: Computing Syzygies, Video

Abstract: I will discuss recent large-scale computations, which utilize numerical linear algebra and highly distributed, high-performance computing to generate data about the syzygies of various algebraic surfaces. Further, I will discuss how this data has led to several new conjectures.

He serves on the NSERC-Mathematical and Statistical Liaison Committee, the CMS Research Committee, and the BIRS Board of Equity, Diversity and Inclusion.

Abstract: Being an openly gay mathematician had a profound impact on my scholarly and personal lives. I will discuss experiences from my time as graduate student in the 1990s, to a pre-tenure faculty member, to the present day as a full professor. While I had challenges to overcome and many more remain, my message is a hopeful one for the next generation of up-and-coming LGBTQ+ mathematicians.
