Nigel Hitchin attended Ecclesbourne School, Duffield, and earned his BA in mathematics from Jesus College, Oxford, in 1968.[2] After moving to Wolfson College, he received his D.Phil. in 1972. From 1971 to 1973 he visited the Institute for Advanced Study and 1973/74 the Courant Institute of Mathematical Sciences of New York University. He then was a research fellow in Oxford and starting in 1979 tutor, lecturer and fellow of St Catherine's College. In 1990 he became a professor at the University of Warwick and in 1994 the Rouse Ball Professor of Mathematics at the University of Cambridge. In 1997 he was appointed to the Savilian Chair of Geometry at the University of Oxford, a position he held until his retirement in 2016. Amongst his notable discoveries are the Hitchin–Thorpe inequality; Hitchin's projectively flat connection over Teichmüller space; the Atiyah–Hitchin monopole metric; the Atiyah–Hitchin–Singer theorem; the ADHM construction of instantons (of Michael Atiyah, Vladimir Drinfeld, Hitchin, and Yuri Manin); the hyperkähler quotient (of Hitchin, Anders Karlhede, Ulf Lindström and Martin Roček); Higgs bundles, which arise as solutions to the Hitchin equations, a 2-dimensional reduction of the self-dual Yang–Mills equations; and the Hitchin system, an algebraically completely integrable Hamiltonian system associated to the data of an algebraic curve and a complex reductive group. He and Shoshichi Kobayashi independently conjectured the Kobayashi–Hitchin correspondence. Higgs bundles, which are also developed in the work of Carlos Simpson, are closely related to the Hitchin system, which has an interpretation as a moduli space of semistable Higgs bundles over a compact Riemann surface or algebraic curve. This moduli space has emerged as a focal point for deep connections between algebraic geometry, differential geometry, hyperkähler geometry, mathematical physics, and representation theory. In his article on generalized Calabi–Yau manifolds, he introduced the notion of generalized complex manifolds, providing a single structure that incorporates, as examples, Poisson manifolds, symplectic manifolds and complex manifolds. These have found wide applications as the geometries of flux compactifications in string theory and also in topological string theory. In the span of his career, Hitchin has supervised 37 research students, including Simon Donaldson (part-supervised with Atiyah). Until 2013 Nigel Hitchin served as the managing editor of the journal Mathematische Annalen.

Tony Pantev received his Ph.D. in 1994 from the University of Pennsylvania. He was a C.L.E. Moore Instructor at MIT, a Sloan Research Fellow, and has held visiting positions at the Isaac Newton Institute in Cambridge, England, the Centro de Investigación en Matemáticas in Guanajuato, Mexico, Ohio State University and the Institute for Advanced Studies in Princeton. He is a professor at the mathematics department of the University of Pennsylvania which he joined in 1997.
Pantev’s research interests include algebraic and differential geometry, Hodge theory, and mathematical physics. Together with Katzarkov, Toen, and Simpson he has obtained fundamental results in non-abelian Hodge theory, that led to the proof of the Shafarevich conjecture for varieties with linear fundamental groups. Together with Donagi he proved Langlands duality for Hitchin systems, a result that applies directly to mirror symmetry. Elaborating on this work, Pantev, jointly with Arinkin, and Block proved the existence of quantization for Fourier-Mukai transforms for general analytic manifolds. In a different direction, Pantev together with Katzarkov and Kontsevich developed the foundations of non-commutative geometry and non-commutative Hodge theory and studied the non-commutative aspects of the mirror correspondence. In an ongoing project with Toen, Vaquie, and Vezzosi, Pantev is exploring a major conceptual advance in derived geometry which was realized through the new notion of a shifted symplectic and Poisson structures.
Pantev has published over 50 peer-reviewed articles, one book, and has edited 3 proceedings volumes. He has supervised 14 PhD dissertations, 8 MSc students, and has mentored 6 postdocs. organized over 25 conferences, workshops, and schools on algebraic geometry, mirror symmetry, and mathematical physics. He serves on the editorial board of Advances in Mathematics, European Journal of Mathematics, and Research in Mathematical Sciences.

The fine-tuning (FT) of the universe for life is the idea that the constants of nature (parameters of physical models of the universe) must belong to very small intervals for life to exist. However, several criticisms have emerged concerning the probabilistic measurement of such life-permitting intervals. Based on a series of recent developments, I present a Bayesian
and maximum entropy framework that addresses several of these concerns. Further, I also present a result that says if tuning is fine or if the level of tuning cannot be assessed for certain families of distributions. Finally, using a recent mathematical theory of learning and knowledge acquisition, I examine whether FT can be learned or if it can only be speculated upon. As a bonus, if time permits, we will also touch on an extension of FT to other areas of science beyond cosmology.

Navigating the transition from AI/ML theory to real-world application is an arduous task within the swiftly evolving AI landscape. This presentation emphasizes the imperative of establishing practical AI and ML principles, testing platforms, and confronting the associated challenges. The transition from conceptual understanding to real-world implementation presents many opportunities in the rapidly evolving landscape of data science. This talk explores the creation of operational platforms for practically testing AI and ML principles, while addressing the myriad of challenges that arise during this process. We will delve into the foundational concepts that underpin AI/ML systems and emphasize the importance of translating these theories into tangible, operational platforms. By doing so, we can uncover the complexities and nuances that often elude theoretical discussions, making way for practical solutions that drive innovation and transformation. We will present a first-of-its-kind platform to highlight the key principles, strategies, and methodologies required to effectively create operational platforms that empower organizations to turn their AI and ML visions into reality, driving meaningful impact and progress in the field. Attendees will gain insights into best practices that empower organizations to actualize tangible advancements in the field.
