Lessons from two years as a sessional instructor at a transfer college

April 4, 2025

ESB 2012 and Zoom

Since defending my PhD in the UBC Mathematics Department in 2023, I have worked as a sessional instructor both at UBC and at Corpus Christi College, which is one of UBC’s affiliate colleges, located at the northeast corner of campus. At UBC, I taught three semesters of an academic and scientific... Read more

Math-Bio: The Social Lives of Viruses

April 2, 2025

ESB4133

Viral infections are social processes. Viral replication requires shared gene products that can be used by multiple viral genomes within the same cell, and hence act as public goods. This gives rise to viral cheats, a type of molecular parasite formed by large deletions, that spread by... Read more

Towards a characterization of elliptic Harnack inequality for jump processes

April 2, 2025

Let $X$ be an isotropic unimodal L\'{e}vy jump process on $\mathbb{R}^d$. We develop probabilistic methods which in many cases allow us to determine whether $X$ satisfies the elliptic Harnack inequality (EHI), by looking only at the jump kernel of $X$, and its truncated second moments. Both our... Read more

Deformations of Special Structures in Dimensions 6 and 7

March 28, 2025

ESB 2012 and Zoom

Conifold transitions are a mechanism in which a Calabi-Yau 3-fold is deformed into another by contracting curves and smoothing out the resulting conical singularities. Reid's Fantasy conjectures that all Calabi-Yau 3-folds can be linked by a sequence of these transitions. It is further... Read more

Transversal projections of fractals

March 26, 2025

2207 Main Mall

The orthogonally projected shadows of a dispersed set in the plane carry much of the information about the shape of the set. The average size of the shadow, known as the Favard length, can be used to study density, structure, distribution, rectifiability, and complex analytical properties such... Read more

The scaling limit of the high-dimensional Ising model is the Gaussian free field

March 26, 2025

In two independent papers, Aizenman and Fröhlich argued that every scaling limit of the critical Ising model in dimensions $d>4$ is trivial (or Gaussian). This qualitative result can be reformulated as follows: the Schwinger functions of any (reasonable) scaling limit satisfy Wick’s law. This... Read more

Math-Bio: Harnessing Mathematical Modeling and Epidemiological Data for Infectious Disease Surveillance and Public Health Decision Making

March 26, 2025

ESB4133

Mathematical modeling, when combined with diverse epidemiological datasets, provides valuable insights for understanding and controlling infectious diseases. In this talk, I will present a series of case studies demonstrating how the synergy between modeling and serological, case-based, and... Read more

2-cell embeddings of cubic graphs

March 25, 2025

ESB 4133 (PIMS library)

Given a graph G, its genus distribution is the sequence whose k-th term is the number of 2-cell embeddings of G in the orientable surface of genus k. The Log-Concavity Genus Distribution (LCGD) Conjecture states that the genus distribution of every graph is log-concave. This has been proven to... Read more
