Talks

Some Recent Talks:

• "Numerical Methods for Geometric Motion" given at the Ottawa Applied Analysis Day (invited lecture) and McMaster Applied Mathematics Seminar, October 2023. A shorter version given at the International Workshop on Recent Developments in Applied Mathematics and its Applications at Caltech, November 2023.

  • 2D curvature motion app (not my work).

  • Gradient flow of Adhesion Energy YouTube video.

• "Asymptotic Error Analysis" given at the UBC PACMAN seminar, September 2023 and previously at the Plovdiv University Mathematical Analyis Seminar, June 2022. This is a general (math) audience talk I have given many times over the years with different applications. 

• "Machine Learning of Electrochemistry Battery Models" given at ICIAM, Tokyo, August 2023. 

• "Enthalpy Methods for Moving Boundary Value Problems" at the British Applied Mathematics Colloquium April 2023. Earlier versions given at the Western Washington University Mathematics Seminar, McMaster Mathematics Colloquium, and the Applied Math Seminar at York University. Accompanying videos:

  • #1 Enthalpy Method for Stefan Problem

  • #2 Enthalpy Method, mushy region

  • #3 Model two phase flow computation

  • #4 Model Sea Ice computation

MATLAB code for implicit Enthaply method in (u,s) formulation.

• "Equivalent formulations of the oxygen depletion problem, other implicit free boundary value problems, and implications for numerical approximation" given at the SIAM PNW chapter meeting, Vancouver WA, May 21, 2022. A longer version given at the Workshop on Interface Problems, June, 2022, Beijing Normal University, Zhuhai.

• Approximating the Arctan function (with many asides), a UBC Archimedes talk March 5, 2022. This is a general audience talk I have given to beginning undergraduates and high school students.
