I am a Canadian Mathematician with interests in Geometry, Algebra and Number Theory. I am primarily based in the Ottawa area and am currently a member of the Laboratory of Birational Geometry at National Taiwan University . My Math Genealogy information is here. My research is supported by NSERC via their Discovery Grant program. Over the years, I have contributed to the Macaulay2 system.
At the Winter 2025 meeting of the Canadian Mathematical Society , I will give a mini-course on the general theme of Mathematical Programming and Network Sciences. Over the next few years, Lie Fu and I will organize some scientific events on the general theme "Cohomological and Arithmetic aspects of orbifold geometry - recent and emerging developments" in support of our recent joint CNRS award. Also, with Emmanuel Haven, I am co-organizing a workshop Workshop on the Use of Quantum Algorithms/Formalisms in Finance which will take place at the Fields Institute , Toronto, this October 2025. Do reach out to me directly in case that you have interest in participating in any of these events.
I was on Faculty at the Department of Mathematics and Statistics at Acadia University from Fall 2023 - Spring 2025. I served as faculty representative to the university research ethics board from Winter 2024 - Spring 2025. During the academic years Fall 2021 - Spring 2023, I was on Faculty at the Royal Military College of Canada.
With colleagues from Acadia University, this past Fall 2024, I helped to organize the highly successful Science Atlantic - Mathematics, Statistics, and Computer Science Conference 2024. The conference took place at Acadia University on 4, 5 October 2024. Also, this Fall 2024, I ran a very well attended AARMS advanced course via Zoom. The title of the course was "A working introduction to Homological Algebra and its applications". This past Fall 2024 semester, I also gave a lecture at the 2024 Winter Meeting of the Canadian Mathematical Society.
During the spring 2022, I co-organized a CIRGET workshop entitled "Geometric and Arithmetic Frontiers of Orbifolds: a focused introductory workshop". The workshop webpage is here. There was a follow-up workshop during spring 2023. The webpage for this past spring 2023 workshop, "Geometric and Arithmetic Frontiers of Orbifolds II: Arithmetic and hyperbolicity", is here. During the winter 2022 semester, I co-organized an informal CIRGET working seminar on Moduli spaces, Algebraic Cycles and related topics. The list of CIRGET seminars and working seminars for the current 2025-2026 academic year is available here.
Over the past few academic years, I have I co-organized the Carleton-Ottawa Number Theory seminar. The seminar webpage for the 2024-2025 academic year is here. The seminar webpage for the 2025-2026 academic year is here.
In December 2023, I co-organized a session Algebraic, Arithmetic and Kahler Geometry: Recent developments at the 2023 Winter Meeting of the Canadian Mathematical Society.
In October 2022, I lectured at the Quebec-Maine Number Theory Conference. During the summer 2022, I attended the workshops 22w5162 and 22w5024 at the Banff International Research Station.
In December 2022, I co-organized a session Diophantine Arithmetic Geometry and Number Theory at the 2022 Winter Meeting of the Canadian Mathematical Society. In January 2022, I co-organized the annual CAAC conference. The workshop webpage is here.
