Faculty Bori Mazzag Mathematics

Dr. Bori Mazzag and Dr. Julie Glass, CSU East Bay, co-organized a series of CSU-wide talks in January as part of the year-long Math Council Colloquium series. The theme of the January talks was “Peer Instruction”. We aimed to connect faculty and staff across the CSU who work on providing academic support services to students in mathematics and statistics courses. In addition to the talks, we collected some information on the structure of the tutoring and peer instruction on the various campuses. CSU campuses were broadly represented in the series, including speakers from Humboldt State University’s Learning Center.

Faculty Peter Goetz, Andrew Conner Mathematics

Published the article “Classification, Koszulity and Artin-Schelter regularity of certain graded twisted tensor products” in the Journal of Noncommutative Geometry, DOI: 10.4171/JNCG/395

Student Cianna Balderama, Daisy Montalvo, Ashley Tran, Ana Sammel, Emma Villegas, Bridget Opperman, Makani Bright, Hunter Kahn, Soeon Park, Tanner Hooven,  Kevin Chung, Diego Rodriguez Moreno  Mathematics

Twelve CNRS students competed in the international Mathematical Contest in Modeling— an annual four day intensive competition. Teams of 3 worked intensely to apply mathematics to a real world problem. Students worked on mathematical models applied to competing populations of fungi, musical influence, and optimizing our nation’s delivery of higher education. The contest happened virtually due to the pandemic.

Faculty Kamila Larripa Mathematics

Kamila Larripa and co-authors had their paper accepted to the Journal of Theoretical Biology. The paper is entitled “Bifurcation and sensitivity analysis reveal key drivers of multistability in a model of macrophage polarization” and investigates how a specific immune cell responds to cytokine signals.

Submitted: October 2, 2020

Faculty Peter Goetz Mathematics

Recently published the single-authored paper “Graded Coherence of Certain Extensions of Graded Algebras” in Communications in Algebra, June 2020, https://doi.org/10.1080/00927872.2020.1775844

The paper studies when the coherence property is inherited by certain extensions of algebras.

Faculty Bori Mazzag, Kamila Larripa, Viri Macias, Megan Johnson, Ana Sammel and Emma Villegas Mathematics

Bori Mazzag and Kamila Larripa each received a CSU PUMP grant to mentor students in mathematical research for the 2020/2021 academic year. Mazzag will investigate calcium dynamics using differential equations and graph theory with Viri Macias and Megan Johnson, and Larripa will model the interaction between Sars-CoV-2 and the host’s immune system, working with Ana Sammel and Emma Villegas.

Faculty Steven Railsback, Bret Harvey Mathematics

Steven Railsback (adjunct faculty, Mathematics) and Bret Harvey (adjunct, Fisheries Biology) just published the book “Modeling Populations of Adaptive Individuals”, volume 63 in the prestigious Princeton Monographs in Population Biology series. The book presents a new kind of theory for adaptive behavior of individual organisms (e.g., when and where to forage, considering both growth and predation risk) that works in complex individual-based population models. The book builds on HSU’s long tradition in individual-based ecological modeling. https://press.princeton.edu/books/paperback/9780691195285/modeling-populations-of-adaptive-individuals
