Looking for new possibilities, Nick Nelson transferred to UWM for its physics program. Eager to learn more through undergraduate research, he worked with professor Philip Chang on a project about classical dwarf novae, leading to new findings and publication in a peer-reviewed journal. After earning his bachelor's degree in physics, Nelson continues to dream bigger as he starts a doctoral program in astronomy and continues working toward a career in astrophysics.

As we start the school year, we would like to extend a huge congratulations to a project that has received a tremendous honor. “Mapping Racism and Resistance” is the recipient of the 2026 Governor’s Archives Award for Archival Advocacy. This project was selected by the Wisconsin Historical Society and Board of Curators. Professor Anne Bonds from Geography and Professor Derek Handley from English have taken the lead on this project along with hundreds of community volunteers. We congratulate everyone involved to make this possible and for earning this well deserved award.

On August 28 at 3:00 PM at the Wisconsin Black Historical Society there will be remarks and notes of appreciation on receiving this award. Please join if you are able to celebrate!

A few years ago, scientists discovered mysterious objects sending short bursts of radio waves at distinct intervals. Thanks to UWM College of Letters and Science professor David Kaplan and an international cohort of astronomers, we’re finally getting a glimpse of what is producing these energy bursts.

Title:
On the Combinatorics of Restricted Skew Dyck Paths

Abstract:
This thesis studies the enumerative combinatorics of skew and restricted Dyck path families. Beginning with classical Dyck paths, non-decreasing Dyck paths, and domino tilings, we review their connections to Catalan numbers and odd-indexed Fibonacci numbers. For partial skew Dyck paths, we use Prodinger’s decorated path framework and the kernel method to obtain level-by-level generating functions and a structural bijection explaining the level recurrence.
The main contribution concerns restricted skew Dyck paths whose valley heights form a non-decreasing sequence. By tracking semi-length and peak count, we derive the bivariate generating function S_UD(x,y)=xy(1-2x)/((1-2x)^2-xy(1-x)). Setting y=1 recovers the total enumeration as a Fibonacci binomial sum. Finally, extracting row polynomials from this generating function shows that the double-indexed array s_UD(n,m) gives a combinatorial realization of OEIS triangle A114164.

📢 Attention all UWM grad students! 📢
 
We’re dropping our 2026-27 call for grad-led public humanities programming early this year to maximize percolation time for the ideas you want to bring to life.

We welcome UWM Master’s & Doctoral students across all disciplines to submit proposals for public humanities programming that takes up our 2026–27 theme: Slow Action. 
 
How might the humanities help us enact organizing as a form of care? What does it look like to build actionable pathways that are anchored in shared values, yet open to change? How do attention and pace shape what’s possible as we face the most pressing challenges of our time?
 
We’re looking for programming that: 
    •    is rooted in humanities practices 
    •    is public-facing & accessible 
    •    is achievable by May 28, 2027
    •    can occur, be presented, or be distributed during C21’s Day of Action, a celebration of the Slow Action theme (ED May 2027)

 
The deadline to apply is Nov. 1, 2026. For more information and to apply, check out the link in our bio! College of Letters & Science

Title:
Convergences groups and Gromov Hyperbolic Spaces

Abstract:
This thesis investigates the relationship between convergence group actions and hyperbolic spaces. Since the 1990s, this relationship has been a significant theme in geometric group theory, revealing deep connections between geometry and dynamics. The goal of this thesis is to provide a streamlined introduction to these ideas and to clarify the proofs of several foundational results.
In particular, we discuss a theorem of Tukia and Freden showing that properly discontinuous actions on hyperbolic spaces induce convergence group actions on their boundaries, and a theorem of Bowditch characterizing convergence group actions through the induced action on the space of distinct triples. Together, these results illustrate how geometric properties of hyperbolic spaces are reflected in the dynamics of group actions on their boundaries.
