Challenges and Opportunities of AI: Evidence on Adoption, Trust, and Bias
Ehsan Mohammadi
University of South Carolina


Abstract: Generative AI and algorithmic systems now shape decisions in health, education, and
scholarship, often faster than anyone can measure what they actually do. In this talk, Dr. Ehsan
Mohammadi, Associate Professor in the School of Information Science at the University of
South Carolina and Director of the Hi Da Research Lab, presents several connected lines of
research on that gap.
He begins with adoption. A survey of academics across 20 countries found heavy use of
generative AI in research and teaching alongside persistent doubts among those same users
about accuracy, transparency, intellectual property, privacy, and bias. He continues with AI
fairness: he discusses an audit of Google Vision AI that failed to identify women and people of
color as scientists and showed an additional intersectional bias affecting women of color. Third,
through the international AI Peer project, he compares large language model outputs against
human expert judgment in academic peer review. He closes with two externally funded AI
literacy initiatives: FLARE A Click here for more information

Title: Variable Importance Identification Through Lazy Training for Binary Classification


Abstract: Deep neural networks have been widely used in many applications (e.g., computer vision and natural language processing); however, understanding their explainability remains a challenging task. Recently, substantial research has been devoted to improving the explainability of deep neural networks, with most of this work focusing on the regression framework. In this paper, we instead focus on the binary classification framework and adopt a variable-importance framework combined with the idea of lazy training to propose an efficient algorithm for identifying important features. From a theoretical perspective, our method relies on only a minimal set of assumptions and achieves well-controlled error rates. The validity of the proposed method and algorithm is examined through extensive simulation studies and real-data applications.

Don’t They Want Us To Succeed?: A Critical Race Counterstory to Deficit Discourses about Students’ Effort in Undergraduate Calculus

Abstract: Nationally, undergraduate calculus is a course with high DFW rates, contributing to persistent racialized disparities in STEM. In response, researchers and practitioners have often drawn on deficit discourses that locate these educational failures within students—particularly Black and Latin* students—framing them as lacking effort or ability. This interactive session presents an analysis of how Black and Latin* calculus students’ experiences talk back to these deficit discourses. We place particular emphasis on our methods to make visible the interpretive decisions that shape qualitative research, challenging notions of detached “objectivity” while engaging the complexities of intersectionality and coalitional solidarity among participants of color with diverse racial and ethnic identities.  Click here for more information

Professor speaking at a colloquium

Colloquium

The math department hosts a colloquium series in which distinguished researchers present their recent work to a general mathematical audience.  All faculty, graduate students and undergraduate students are welcome.

View a short video about our Colloquium series

Organizer: Jeremiah Birrell

Algebraic Combinatorics Reading Seminar

This seminar meets about once a week.  The format is very informal, the idea is that we collectively select a topic for the semester and present material surround that theme.  Original research is not typically presented and we encourage participation from all levels. Graduate students with an interest in algebra/combinatorics are especially encouraged to attend. 

For more information or to be included in communication regarding this seminar please contact Anton Dochtermann.

Differential Equations and Applied Math Seminar (DEAM)

The Differential Equations and Applied Math Seminar is a seminar for those interested in differential equations, mathematical modeling, mathematical physics, scientific computation, and any other interdisciplinary mathematical work of an applied nature.  The speaker's topics are not restricted to their own work, as this seminar is a platform for presenting details of mathematics of interest.  Interested faculty, graduate students, and advanced undergraduates are encouraged to attend.

Organizers: Ray Treinen & Nestor Guillen

Discrete Math Seminar

All faculty, graduate students, and upper level undergraduate students are welcome. The seminar will provide a platform for faculty and students to present their research developments in discrete mathematics and related areas, foster research interactions among faculty and students, and create research opportunities and collaborations for faculty and students. Speakers from Discrete Mathematics, Combinatorics, Computer Science, and other related areas are all welcome. We are particularly interested in interdisciplinary research which applies mathematics as a tool to solve problems in other areas such as CS, BioInformatics, Bio‐sciences, Engineering, Physics, Chemistry, etc.

Organizer: Jian Shen
