Mirror Lab Symposium: Frontiers in Recent Human Evolution

We will describe and discuss projects that explore genetic variants that emerged in the evolution of modern and archaic humans, and how such archaic variants affects humans today. We will also discuss projects that use ancient DNA to reconstruct the early peopling and history of the Japanese Archipelago. We will explore how we can intensify our collaborations in these areas and brainstorm about future research directions.

This talk will explore some aspects of non-smooth Lorentzian geometry, the mathematical framework underlying Einstein’s general relativity, which is currently being developed. Just as metric length spaces provide a synthetic generalisation of smooth Riemannian manifolds, the time-separation function plays the role of a “distance” in Lorentzian geometry. The need for a non-smooth Lorentzian framework appeared early on, most famously with Penrose’s singularity theorems. After introducing the basic concepts and some initial results in this synthetic setting, we will turn to causal set theory, a radical approach to quantum gravity in which spacetime is modelled as a discrete causal graph. I will formulate a new notion of curvature, inspired by Ollivier-Ricci curvature on metric graphs, using optimal transport between causal diamonds. We will see that it does recover Ricci curvature on smooth Lorentzian manifolds, and numerical examples will be presented.

Title: Rocks instead of clocks: Bayesian modelling of the fossil record enlightens the diversification and extinction of Hemiptera in deep time

Abstract: Untangling the patterns and drivers behind the diversification and extinction of highly diversified lineages remains a challenge in evolutionary biology. While insect diversification has been widely studied through the “ Big Four” insect orders (Coleoptera, Hymenoptera, Lepidoptera, and Diptera), the fifth most diverse order, Hemiptera, has often been overlooked. Hemiptera exhibit a rich fossil record and are highly diverse in present-day ecosystems, with many lineages closely associated with their host plants, making them a crucial group for studying how past ecological shifts—such as mass extinctions and floral turnovers—have influenced insect diversification. This study leverages birth-death models in a Bayesian framework and the fossil record of Hemiptera to estimate their past diversity dynamics. Our results reveal that global changes in flora over time significantly shaped the evolutionary trajectories of Hemiptera. Two major faunal turnovers particularly influenced Hemiptera diversification: (i) the aftermath of the Permo-Triassic mass extinction and (ii) the Angiosperm Terrestrial Revolution. Our analyses suggest that diversification of Hemiptera clades was driven by floristic shifts combined with competitive pressures from overlapping ecological niches. Leveraging the extensive fossil record of Hemiptera allowed us to refine our understanding of diversification patterns across major hemipteran lineages. We also the recently developed Bayesian Brownian Bridge model, which estimates the timing of lineage origin and extinction through fossil-based Bayesian modelling, to provide a temporal framework for the rise and fall of 310 major hemipteran lineages.

The 10th OIST-Keio Joint Symposium brings together various perspectives on fluid dynamics, highlighting recent advances across theory, computation, and experiment. Through a series of focused talks and poster presentations, the event spans fundamental flow phenomena, complex and multiscale fluids, and engineering‑relevant applications. This 10th showcase continues a series of events bringing Keio and OIST researchers together to foster discussion and enable innovation through interdisciplinary collaboration.

Japan’s next wave of global innovation is emerging from the south. This roundtable session, co-hosted by OIST Innovation and Kyushu University Kyusokai , explores the strategic potential of the Okinawa–Kyushu axis as a powerhouse for national-level Deep Tech.

Join us to discuss how we can leverage our unique geographic and academic strengths to create a sustainable supply base for world-changing technologies. We will move beyond theory into the practical realities of venture capital and domain-specific scaling.

Title : "Introduction to Isogeny-based Cryptography"

Abstract : Isogeny-based cryptography is a fast-moving field, and recent developments have introduced several new techniques, making the barrier of entry particularly high for young researchers wishing to work in the field. To aid new researchers in the field is the aim of this "summer" school, which introduces all of the many essential tools that are used today. Among the topics to be covered are the correspondences between ideals and isogenies that give rise to both the Deuring correspondence, which is an essential part of protocols such as SQIsign, and the class group action on CM curves and oriented supersingular curves, which gives other cryptographic primitives such as CSIDH and SCALLOP. Further, higher dimensional abelian varieties and isogenies between these have recently become an integral part of isogeny-based cryptography, providing huge improvements to many existing protocols, as well as creating new protocols.

Abstract: I will describe the resolution of two conjectures related to Dirichlet forms. In both cases a conceptually simple solution arises by stepping away from the p=2 regime. This leads to a new definition of a p-Dirichlet space, which unifies three quite different areas: Dirichlet form theory, Analysis on fractals and Analysis on metric spaces. The talk includes joint work with Mathav Murugan

Abstract: Classical Sobolev trace theory tells us when a boundary map can be extended as a Sobolev function inside a given domain in R^n. For the purposes of minimization problems in Nonlinear Elasticity, it is natural to rephrase this question in the context of extending a given embedding of the boundary as a homeomorphic Sobolev map. In this talk, I will explain what is known about this problem, ending with a full trace theory for Sobolev homeomorphisms in 2D.
