When Andr\u00e9s R. Vindas Mel\u00e9ndez, assistant professor of mathematics at Harvey Mudd College, speaks about mathematics, it\u2019s not formulas or theorems that dominate the conversation, it\u2019s artistry. Starting in January 2026, thanks to a new two-year National Science Foundation grant, that sense of mathematical wonder will translate into a hands-on research program.<\/p>\n\n\n\n
The grant will fund his research through December 2027 and will provide funding for four undergraduates per summer for two summers to explore the world of geometric combinatorics, a field in which geometry, combinatorics, and algebra come together to uncover the underlying structure of complex shapes and patterns.<\/p>\n\n\n\n
For the next two summers, Vindas Mel\u00e9ndez will mentor students over 10 weeks. Participants will collaborate on original problems, many drawn from Ehrhart theory, which studies the properties of polytopes (multi-dimensional generalizations of polygons) by counting lattice points, grid-like dots with whole-number coordinates inside or on the edges of shapes.<\/p>\n\n\n\n
\u201cI want to take combinatorial objects\u2014graphs, posets, polytopes\u2014and associate them with geometric objects,\u201d says Vindas Mel\u00e9ndez. \u201cBy studying these objects\u2019 structures, we hope to understand something deeper about the original mathematical ideas behind them.\u201d<\/p>\n\n\n\n
Students won\u2019t be working from pre-made datasets or repeat experiments. \u201cThey\u2019ll write their own code, build their own data and search for patterns in the geometry,\u201d he says.<\/p>\n\n\n\n
Combinatorics is often called \u201cfancy counting,\u201d Vindas Mel\u00e9ndez says, but it\u2019s more accurately about how objects are classified, arranged, and enumerated. \u201cGeometric combinatorics adds a spatial dimension to that,\u201d he says.<\/p>\n\n\n\n
Combinatorics is about distilling complex structures into simpler, manageable parts. While humans may not be able to visualize a six-dimensional shape, for example, computers can. Students will use code to define, manipulate and analyze these mathematical objects, blending abstract theory with hands-on computation.<\/p>\n\n\n\n
There are real-world implications. Polytopes appear in natural sciences, data science and optimization problems. They show up in crystal structures, biological cell shapes and even tiling patterns used in architecture and manufacturing.<\/p>\n\n\n\n
One exciting aspect of the program is its focus on younger undergraduates, those who may just be finishing their first year and haven\u2019t yet had much exposure to upper-level mathematics.<\/p>\n\n\n\n
\u201cIt\u2019s really powerful to show students early on that they can do math research,\u201d Vindas Mel\u00e9ndez says. \u201cThey don\u2019t need to wait until junior or senior year to start exploring.\u201d<\/p>\n\n\n\n
Vindas Mel\u00e9ndez emphasizes inclusion, aligning with federal regulations that require opportunities be open to all. He has consistently mentored a diverse range of students, including women, first-generation college students and students from underrepresented backgrounds in STEM. \u201cThis past summer, half of my research team were women,\u201d he says. \u201cI want students from all walks of life to feel they belong in mathematics.\u201d<\/p>\n\n\n\n
While geometric combinatorics has roots stretching back to the ancient Greeks and Euler\u2019s famous polyhedral formula, the field has exploded in new directions over the past few decades.<\/p>\n\n\n\n
\u201cThe growth of interdisciplinary approaches\u2014combining algebra, number theory, geometry, combinatorics, and many other areas\u2014has really moved this field forward,\u201d Vindas Mel\u00e9ndez says.<\/p>\n","protected":false},"excerpt":{"rendered":"
