Arielle Carr
Bio
I am an assistant professor at Lafayette College in the
Department of Mathematical Sciences.
My research focus is in the fields of applied linear algebra, applied numerical analysis,
and scientific computing. I earned my PhD in math from Virginia Tech in 2021, a BS (2012)
and MS (2015) in math with a minor in computer science from VT, and a BA (2008) in sociology
with a minor in education from Roanoke College. I am an expert in iterative methods for solving
large linear systems and eigenproblems. In particular, I work with Krylov subspace methods and
preconditioning techniques to develop novel and innovative algorithms that achieve efficient
and accurate solutions to important problems in a wide range of fields
in science and engineering. Recently, I have extended this to applications arising in emerging
and novel technologies such as quantum computing and machine learning. I am also an experienced
educator with over ten years teaching undergraduate and graduate courses in mathematics and
computer science. Having previously taught middle and high school mathematics, I retain a deep
understanding and appreciation for cultivating strong foundational skills in STEM fields and
incorporate pedagogical approaches in my collegiate classrooms that build on techniques learned
when teaching at the secondary level. I have a strong passion for promoting the success of
underrepresented people in different fields, particularly for women in traditionally male fields
such as applied mathematics. I dedicate my professional service to efforts that
directly address this lack of representation, drawing on my experience studying and
researching gender roles in the workplace in my undergraduate studies.

SIAM members: As part of my Science Policy Fellowship project, I am researching gender perceptions of scholarly funding. Please consider completing my short survey, whose results will hopefully allow me to provide meaningful feedback to SIAM about how to strengthen existing efforts to ensure fairness in funding. Find more information and a link to the survey here.

Call for Undergraduate Researchers
- Undergraduate students, are you looking for research opportunities? Research affords you the opportunity to learn outside
of the constraints of a course, or textbook, or homework assignment. It provides you with valuable experience that ultimately
supports a wide range of careers in both academia and industry. For those of you with ambition to pursue graduate study,
undergradaute reserach allows you to experience the rigors -- and joys -- of academic research, while also augmenting your dossier
meaningfully and competitively when applying to schools. I have openings every semester for undergraduate research. In all cases,
credit can be offered for work completed. In exceptional cases, students may earn a competitive stipend. Please navigate to my
Research page for a description of current projects, and my
Papers page for a list of current and past students' projects. If you are interested in working
with me, reach out as soon as possible to ensure full consideration for a spot for the semester.
I am actively seeking student researchers to start as early as Fall 2026.
