KAP

I recently completed my Ph.D. in Mathematics at Georgia Tech, where I was advised by Jen Hom. My research focuses on problems in low-dimensional topology, primarily from the perspective of knot Floer homology and bordered Heegaard Floer homology. At UC Davis, I look forward to working with Melissa Zhang and broadening my approach by exploring new tools for studying knots and links in 3- and 4-manifolds.

I am a Mexican mathematician with a strong interest in discrete geometry, convexity, graph theory, matroids, and combinatorial problems in general. I earned my master’s degree at the Universidad Nacional Autónoma de México (UNAM) and completed a joint Ph.D. at UNAM and the Université de Montpellier. My research focuses on bodies of constant width, Reuleaux polytopes, and the development of new approaches in these areas of mathematics.

Chris studies theoretical computer science, with a focus on convex optimization, on random matrices, and on connections between theoretical computer science, pure mathematics, and statistical physics (e.g. sphere packing, spin glasses). Prior to coming to Davis, he was a postdoc at Bocconi University in Milan, and he received his Ph.D. in 2022 from the University of Chicago. Chris also likes designing crossword puzzles and puzzle hunts. On his days off, he likes to enjoy nature and swim in alpine lakes.

Kiseok Yeon joined UC Davis as a Krener Assistant Professor this Fall quarter. His main research interest lies on analytic number theory (especially the Hardy-Littlewood method), theory of exponential sums and its applications, and analytic methods in connection with rational points on varieties. 

Aside from mathematics, he loves playing tennis and running. He would love to be contacted if Department members want to do exercise together – he loves all kind of exercises!
 

Oliver Siebert works in mathematical quantum theory, mainly using tools from functional analysis (including spectral theory, operator theory, operator algebras). Currently, he is interested in many-body theory with applications to quantum information (Lieb-Robinson bounds, area laws), and in non-relativistic QED/Pauli-Fierz Hamiltonians. He completed his Ph.D. in 2021 at the University of Jena under the supervision of David Hasler. Following that, he worked as a postdoc with Marius Lemm at EPFL and the University of Tübingen.

Jared Krandel is a new KAP who will be starting at UC Davis in January 2025. He graduated from Stony Brook University in Spring 2024 and is spending this Fall as a postdoc at SLMath in Berkeley. Most of his work so far has been in an area of geometric measure theory called quantitative rectifiability. He studies geometric properties of rectifiable curves and surfaces through things like analyst's traveling salesman problems, characterizations of uniform rectifiability, parameterizability problems, and more. 

Anna Zarkh received her Mathematics Education Ph.D. in May 2024 from the University of California, Berkeley. She holds B.A. and M.A. degrees in Mathematics from Bar Ilan University in Israel. Anna’s research focuses on university mathematics education, specializing in socio-cultural theories, discourse analysis, and micro-ethnographic methods. She is interested in the historical development and effects of communication practices in contemporary academic mathematics.

Yoon Jae "Nick" Nho is a Krener Assistant Professor, mentored by Professor Roger Casals. His research is in symplectic geometry and topology, and he is interested in geometric structures that are related to physics. He received his Ph.D. from the University of Cambridge in August 2024, under the supervision of Professor Ailsa Keating. 

He is from South Korea, and his hobbies include reading books, watching films, and listening to music.

Chenchen Zhao completed her Ph.D. at the University of Southern California in May 2024, advised by Greta Panova. Her research interests lie in the area of Enumerative and Algebraic Combinatorics. Her dissertation explored the positivity of Kronecker coefficients and the Newton polytope of the Kronecker product of Schur polynomials.
