Walter D. Neumann, 1946-2024

It is with deep sadness and heavy hearts that we inform you of the death of Prof. Walter Neumann, who passed away yesterday. Heartfelt condolences are extended to his family, friends, and loved ones.

Walter received his PhD at Bonn University in 1969 and became a Barnard Professor in 2000. He was a member of the European Academy of Sciences (elected 2002) and a Fellow of the American Mathematical Society since 2012. He worked in geometry and topology and especially on low dimensional topology, for example on hyperbolic 3-manifolds and geometric group theory.

A website with a cv, autobiographical account of his early life, a celebration written by Alan W. Reid, a list of his PhD students, and a gallery of pictures can be found here:

A Zoom memorial will be held in his honor for family, friends, and colleagues; additional details will be announced in the near future.

Ivan Corwin, Professor of Mathematics and 2014 Packard Fellow in Science and Engineering, has been awarded a $40,000 award as part of the Increasing Diversity in STEM pilot program for Packard Fellows. The award will support the “Pathways for Women into Higher Mathematics” project.

The Packard Foundation’s goal in this initiative is to support Fellows’ efforts to increase the representation and inclusion of underrepresented groups (URGs) in their departments and universities.

The Pathways for Women into Higher Mathematics project will involve two pathway activities for women interested in mathematics to help guide them towards the possibilities that lay ahead in higher mathematics: the organization of the “Sonya Kovalevsky Day” for middle school aged students and a two-day Graduate Opportunities for Women (GROW) Conference to take place in 2024 and 2025.

Named after the Russian pioneer woman mathematician, the “Sonya Kovalevsky Day” will bring primarily female middle schoolers from NYC’s under-resourced schools and their teachers to Columbia to engage in hands-on workshops led by faculty and students.

The GROW Conference will bring women (cisgender, transgender, or woman-identified) and non-binary undergraduate students, primarily from non-tier I colleges or universities, to help them envision a potential career and graduate study in mathematics or statistics. GROW has been running for about 10 years, in rotating locations, and has engaged over 1,000 students over its duration.

The Packard Foundation’s support will be complemented with financial support and extensive mentorship and organizational support from the Columbia Mathematics and Statistics departments, as well as the Irving Institute for Cancer Dynamics. Corwin summed it up, saying, “these pathway activities will add to many exciting ongoing efforts at Columbia to attract a diverse population of students to higher mathematics and retain their interest and excitement.”

With profound sadness and grief we write to share the passing of Henry Pinkham, who recently passed away. Professor Pinkham was a beloved member of the department for nearly 50 years, and also served as the Dean of the Graduate School of Arts & Sciences for 9 years. Our heartfelt condolences go out to family, friends, and colleagues. His presence in our department will be dearly missed.

In Memoriam of Professor Henry Pinkham

Donations may now be made online to a fund in memory of Michael Zhao, a doctoral student in the Department who passed away on December 8, 2018.

Michael Zhao was an outstanding undergraduate at the University of Utah, graduating in 2017.  He completed Part III at the University of Cambridge and began here as a doctoral student in September 2018, only a few months before his tragic death.  He had planned to specialize in number theory.  Everyone here was devastated by the loss of such a promising young scholar.

Donations to the memorial fund may be made here:

http://www.math.columbia.edu/giving/michael-zhao-memorial/

Funds may be used for a physical memorial to Michael in the Department, for expenditures to benefit doctoral students in the Department, or both.  Please give generously.

The Department mourns the sudden and unexpected loss of its first-year doctoral student, Michael Zhao.  Michael was an outstanding undergraduate at the University of Utah.  He came here after spending a year as a Part III student in Cambridge.  Michael had made a promising start on his doctoral studies here and was planning to specialize in number theory or algebraic geometry.  He is survived by his parents, Shaoqing Song and Fuli Zhao, and by a brother, Alan Zhao.  The Department will announce a memorial gathering for him in the near future.

Funeral Arrangements have been made, as follows:
