Much of my work involves combinatorial models for topological structures such as differential manifolds and vector bundles. The aims of such models include both combinatorial answers to topological questions (e.g., combinatorial formulas for characteristic classes), and topological methods for combinatorics (e.g. on topology of posets).\\ \\ ~~codedoc:xref:rbieri~~ **[[people:rbieri:start|Robert Bieri]]** - Visiting Professor\\ **Areas of Interest:** Geometric, homological, combinatorial and asymptotic methods in group theory\\ **Description:** My original interest in homological methods for infinite groups (cohomological dimension and Poincare type duality) shifted towards geometric and -- more recently -- asymptotic methods. I find it interesting to relate geometric properties at infinity of groups and G-spaces with algebraic properties of these groups, their group rings and their modules. The focus is on familar groups like metabelian, soluble, free and linear ones, or fundamental groups of 3-manifolds, but I also met Thompson's group F and other PL-homeomorphism groups on the way, and had an encounter with tropical geometry.\\ \\ ~~codedoc:xref:borisov~~ **[[people:borisov:start|Alexander Borisov]]** - Associate Professor\\ **Areas of Interest:** \\ **Description:** My general research area is algebraic geometry and number theory, broadly interpreted.

I am particularly interested in high-dimensional, "big data" modeling, and functional data analysis. My genetic leaf shape project was awarded a three-year NSF grant. I enjoy collaborating on interdisciplinary projects, working with researchers from the application domains and addressing real-life data analysis questions.\\ \\ ~~codedoc:xref:jhyde1~~ **[[people:jhyde1:start|James Hyde]]** - Assistant Professor\\ **Areas of Interest:** \\ **Description:** \\ \\ ~~codedoc:xref:qiqbal~~ **[[people:qiqbal:start|Quaid Iqbal]]** - Robert Riley Visiting Assistant Professor\\ **Areas of Interest:** \\ **Description:** \\ \\ ~~codedoc:xref:dikran~~ **[[people:dikran:start|Dikran Karagueuzian]]** - Associate Professor\\ **Areas of Interest:** Algebraic topology, representation theory, group cohomology\\ **Description:** My research for the past few years has been primarily in the representations and cohomology of finite groups. For the past few years I have been studying problems in algebra that arise from techniques of algebraic topology. Sometimes there is a theorem hidden behind the feasibility of a well-known method. An example of this phenomenon is my most recent preprint, written in collaboration with Peter Symonds of the University of Manchester Institute of Science and Technology. In this case the theorem was uncovered through exploration with the computer algebra package Magma, which is well worth checking out. Often such software lets us investigate mathematical phenomena which would be very difficult to understand otherwise.\\ \\ ~~codedoc:xref:kargin~~ **[[people:kargin:start|Vladislav Kargin]]** - Associate Professor\\ **Areas of Interest:** \\ **Description:** I am particularly interested in random matrices and its applications, in particular, statistical analysis of large data, zeroes of zeta functions, statistical mechanics of random media, and free probability.\\ \\ ~~codedoc:xref:tlee40~~ **[[people:tlee40:start|Tae Young Lee]]** - Robert Riley Visiting Assistant Professor\\ **Areas of Interest:** Finite groups and their representation theory\\ **Description:** I am interested in finite (or sometimes algebraic) groups, their representations, and connections to other topics in mathematics. My last few papers were about local systems (continuous representations of étale fundamental groups) and their monodromy groups (the images of these representations). I classified a specific kind of local systems, called hypergeometric sheaves, when they have specific type of finite monodromy groups, using representation theory of these groups and some number theoretic method. I would be also happy to discuss general problems about finite groups and their representations, or even some problems in discrete mathematics with algebraic points of view.\\ \\ ~~codedoc:xref:loya~~ **[[people:loya:start|Paul Loya]]** - Associate Professor\\ **Areas of Interest:** Global and geometric analysis, Elliptic theory of differential operators on manifolds with singularities, Partial differential equations\\ **Description:** The underlying theme of my research is the investigation of topological, geometric, and spectral invariants of (singular) Riemannian manifolds using techniques from partial differential equations. For example, the Euler characteristic of a surface is a topological invariant based its usual definition in terms of a triangulation of the surface. However, it may also be considered geometric in view of the Gauss-Bonnet theorem or spectral in view of the Hodge theorem. I am interested in such relationships on general singular Riemannian manifolds.\\ \\ ~~codedoc:xref:malkiewich~~ **[[people:malkiewich:start|Cary Malkiewich]]** - Associate Professor\\ **Areas of Interest:** Algebraic topology, especially stable homotopy theory, algebraic K-theory, applications to manifolds and cell complexes.\\ **Description:** My primary research area is algebraic topology. I like to apply stable homotopy theory (spectra) to questions about manifolds and cell complexes. My work has taken a recent turn towards scissors congruence: in 2002 I proved that it is described by a Thom spectrum, and I am developing the consequences of this surprising result for the higher scissors congruence groups.\\ \\ ~~codedoc:xref:mazur~~ **[[people:mazur:start|Marcin Mazur]]** - Professor\\ **Areas of Interest:** Algebraic number theory, group theory\\ **Description:** My research interests concentrate around areas where number theory and group theory intersect.

I have done some work in the study of the relationship between exotic structures and (negative, non-positive) curvature, and its applications to the limitations of PDE methods in geometry. Other interests: geometric group theory, K-theory, mechanics.\\ \\ ~~codedoc:xref:aleksey~~ **[[people:aleksey:start|Aleksey Polunchenko]]** - Associate Professor\\ **Areas of Interest:** Statistics, sequential analysis.\\ **Description:** Mathematical statistics and specifically the problem of sequential (quickest) change-point detection, currently focusing on the case of composite hypotheses.\\ \\ ~~codedoc:xref:qiao~~ **[[people:qiao:start|Xingye Qiao]]** - Professor and Chair\\ **Areas of Interest:** Statistics, machine learning, causal inference\\ **Description:** My research interests encompass statistics, machine learning, and data science.

My current and future research focuses on developing this understanding by means of (a) design and analysis of screening experiments, implying the efficient planning and execution of high-dimensional experiments, and (b) developing statistically- and computationally-efficient subdata selection tools, facilitating the extraction of vital insights from large and ever-growing datasets while maintaining quality. In particular, the designs used for the screening experiments frequently exhibit constrained practical applicability due to (a) a disconnect between existing design selection criteria and the methods used for their analysis, (b) their traditional construction and analysis within the confines of the main effects model, despite real experimental dynamics being influenced by interactions, and (c) a scarcity of simulation and empirical studies illustrating the contexts wherein these designs hold significance versus when they do not. I focus on mitigating these challenges by means of developing the efficient design and analysis of screening experiments. I harness high-performance computing to develop analytically rigorous tools for advanced "design of experiments" and "sampling" to better understand these high-dimensional stochastic processes. \\ \\ ~~codedoc:xref:daniel~~ **[[people:daniel:start|Daniel Studenmund]]** - Assistant Professor\\ **Areas of Interest:** \\ **Description:** My research addresses questions arising at the intersection of geometric group theory and the study of discrete subgroups of Lie groups. I am particularly interested in invariants associated to the collection of finite-index subgroups of a given group G. One example is the abstract commensurator Comm(G), the group of all isomorphisms between finite-index subgroups of G, modulo equivalence. Other examples are growth rates of various functions associated to the collection of finite-index subgroups, which can be thought of as helping to quantify residual finiteness of G. I also study other invariants of groups, such as superrigidity and cohomology of arithmetic groups, using algebraic and geometric methods.\\ \\ ~~codedoc:xref:tongviet~~ **[[people:tongviet:start|Hung Tong-Viet]]** - Professor\\ **Areas of Interest:** Representation theory and character theory of finite groups, permutation groups and abstract finite groups.\\ **Description:** My main research interests lie in the representation and character theory of finite groups, permutation groups and applications to number theory and combinatorics, and finite group theory in general. I am interested in studying groups or group structures using several important numerical invariants of the groups such as character degrees (ordinary and modular), p-parts of the degrees or character values such as zeros of characters. In permutation group theory, I study derangements, that is, permutations without fixed points, and their applications in number theory and graph theory, permutation characters and permutation polytopes. Recently, I am also interested in studying the influence of real conjugacy class sizes on the group structures.\\ \\ ~~codedoc:xref:tnhattran~~ **[[people:tnhattran:start|Tan Nhat Tran]]** - Robert Riley Visiting Assistant Professor\\ **Areas of Interest:** Algebraic Combinatorics, Hyperplane Arrangement\\ **Description:** I am dedicated to research in combinatorics, and especially its connections with commutative algebra, algebraic topology and probability theory. My research over the past few years has focused on the theory of arrangements of hyperplanes, especially how the combinatorial properties of hyperplane arrangements interact with the discrete geometric structures (e.g., graph, polytope, root system), topological objects (e.g., Poincare ? polynomial, CW-complex), algebraic concepts (e.g., logarithmic derivation, Hopf algebra) and probabilistic models (e.g., expectation, vine copula).\\ \\ ~~codedoc:xref:dvanniel~~ **[[people:dvanniel:start|Danika Van Niel]]** - Robert Riley Visiting Assistant Professor\\ **Areas of Interest:** Algebraic and Geometric Topology\\ **Description:** \\ \\ ~~codedoc:xref:adrian~~ **[[people:adrian:start|Adrian Vasiu]]** - Professor\\ **Areas of Interest:** Arithmetic Algebraic Geometry\\ **Description:** My area of research is Arithmetic Algebraic Geometry, which is the common part of Number Theory, Algebra, and Geometry.
