LUMS provides its PhD students with opportunities to engage with academic communities worldwide. Two students from the Department of Mathematics, Muhammad Ameer Hamza and Mughees Ghayas, recently participated in a staff exchange initiative at the University of Valencia, Spain, under the EU-funded CaLIGOLA program. This exchange, held from November 13 to December 28, 2024, aimed to promote international collaboration and advance research in areas such as Cartan Geometry, Lie Theory, Integrable Systems, and Quantum Groups.

Muhammad Ameer Hamza's Research on Topological Data Analysis
Hamza, a PhD student specializing in Topological Data Analysis under the supervision of Dr. Haniya Azam (Assistant Professor, Mathematics) and Dr. Hassan Mohy-Ud-Din (Assistant Professor, Electrical Engineering), focused on the topological regularization of image segmentation using deep learning methods. His project aimed to improve methods for segmenting 3D MRI scans, particularly in distinguishing cardiac structures like the left ventricle, right ventricle, and myocardium. To support this work, Hamza used computational tools such as Google Colab with A100 GPUs to calculate Wasserstein distances between persistence diagrams of predicted segmentation and the ground truth, a necessary step in diagnosing cardiovascular diseases.
During his visit, Hamza gave a talk on "Topological Data Analysis: A Naïve Introduction," discussing its applications in areas like string theory, biology, and chemistry. He also collaborated with Dr. María Antonia Lledó Barrena on double geometry, which allowed him to explore complex linear algebra and the structure of manifolds. After his time in Valencia, Hamza extended his research journey to Aarhus University in Denmark, where he worked with Dr. Simon Kristensen and Nikita Shugla on Diophantine approximation theory, exploring problems in continued fractions.

Mughees Ghayas' Research on Algebraic and Combinatorial Properties
Mughees Ghayas, a PhD student under the supervision of Dr. Imran Anwar, focused on the asymptotic behavior of Inc(N) invariant monomial ideals, particularly their algebraic and combinatorial properties. His research lies at the intersection of algebraic geometry and combinatorics, revealing patterns in infinite algebraic structures. During the visit, Mughees concentrated on conjectures about Cohen-Macaulay properties of simplicial complexes and the asymptotic behavior of ideals under combinatorial constraints.
Mughees presented his research weekly to Professor Marian Lledó at the University of Valencia. These presentations led to discussions that helped refine his research, including exploring applications in theoretical physics. He also delivered a seminar at Universidad Autónoma de Madrid, where he had discussions with faculty members such as Dr. Beatriz Pascual, Dr. Ana Bravo, and Dr. Adolfo Quirós, which opened potential future research opportunities.

Collaborations and Research Development
The visit to the University of Valencia provided both Hamza and Mughees with the chance to deepen their research and engage in international collaborations.
Both students expressed appreciation for the support of their supervisors, Dr. Haniya Azam and Dr. Imran Anwar, and thanked Dr. Walther Schwarzacher, Dean of SBASSE, for facilitating the funding and support that made their exchange possible.
This initiative reflects LUMS’ commitment to fostering global research connections, enabling students to advance their work and bring valuable international experience back to the institution.
