Seminar

Seminar: From alpine beetle populations to Cretaceous moth radiation: can we connect the dots between microevolution and macroevolution?

Monday, June 12, 2023 - 14:00 to 15:00
OIST Main Campus (C700)

Abstract Population genetics and phylogenetics are two main subfields of evolutionary genetics. The former investigates the genetic variations among populations within a species while the latter focuses on reconstructing phylogeny of many species using genetic data. In this presentation, I will present my previous work on the population genetics of an alpine ground beetle, Nebria ingens complex, in the Sierra Nevada in California and my current work on the deep evolutionary history of species radiation of Lepidoptera. In the alpine ground beetle study, I used genome-wide variants to characterize the population structure and demographic history. I found that the glacial refugia was in the low-elevation drainage basins of Sierra Nevada during the last glacial maximum, followed by the postglacial recolonization to the current high-altitude alpine zone. I also used genome-wide association approaches to identify the genes putatively associated with the postglacial elevational range shift, local adaptation to the heterogeneous environments, and the morphological variations. For the study of Lepidoptera species radiation, I use published high-quality lepidopteran genomes to explore the genomic evidence related to rapid diversification of modern lepidopteran lineages. The preliminary results suggest that the gene evolution involving host plant detection, phytocompound detoxification, and protein digestion play crucial roles in species diversification along with the Angiosperm radiation. Finally, I will provide my personal perspective on connecting population genetics (microevolution) and phylogenetics (macroevolution) for a more thorough understanding of evolutionary processes.

About Dr. Yi-Ming Weng: Yi-Ming was born and brought up in Taiwan. He graduated from National Chung-Hsing University for bachelor’s and master’s degrees in Entomology department. He is interested in insect biodiversity and evolution in general. For his master thesis, he studied phylogeography of alpine ground beetles in Taiwan, looking for sharing evolutionary history between the alpine ground beetle species with similar ecological niche and geographical distribution. Yi-Ming started his PhD carrier in the University of Wisconsin-Madison in 2017. He worked with Professor Sean Schoville to further study the evolutionary history of alpine ground beetle from the Sierra Nevada in California using genomic data. By the time he started to develop his skillsets in bioinformatics and genomics. Now Yi-Ming is working with Professor Akito Kawahara in the University of Florida as a postdoctoral researcher studying evolutionary genomics of Lepidoptera.

Despite Yi-Ming has been working mostly with computers for his bioinformatics analyses, he is most interested in outdoor activities and direct observation of insects. He believes that good biological questions usually come from the field, and stepping out to touch the insects gets the best inspiration.

Seminar

[Seminar] Critical Sobolev Spaces and Subspaces of BMO, Professor Daniel Spector, National Taiwan Normal University

Monday, June 19, 2023 - 10:00 to 11:00

Abstract: It is well-known that functions in critical Sobolev spaces embed into the space of functions of bounded mean oscillation (BMO) originating in the work of John and Nirenberg. Less well-known is the fact that they actually embed into BMO on subspaces of every smaller dimension. In this talk we introduce a class of spaces which are finer targets of these critical Sobolev embeddings than BMO that capture this phenomena, which we term beta-dimensional BMO. Interestingly, these spaces also gives an answer to the question of which BMO functions admit restrictions in BMO of subspaces. The key tool is a capacitary analogue of the John-Nirenberg inequality for the Hausdorff content, obtained recently in a joint work with You-Wei Chen.

Lecture 1 Tuesday, June 20 10 am Title: Riemann and Lebesgue Integration Abstract: The Riemann integral is perfectly suited for consideration of volume, surface area, arc length, and integration of functions in classical analysis - when the sets in question are smooth and the functions in question continuous. In this talk, we introduce these ideas and explain the progression from Riemann integration to Lebesgue integration, emphasizing in particular the powerful tools one obtains from this construction. Lecture 2 Wednesday, June 21st 10 am Title: Capacitary Integration Abstract: The Lebesgue integral provides one with a satisfactory tool for many purposes in mathematical analysis. Yet in the modeling of natural phenomena, with the introduction of partial differential equations, integrals which are not Lebesgue integral makes a prominent appearance - capacitary integrals. In this talk we discuss this motivation for capacitary integration, with examples, explain the differences with Lebesgue integration, and show the usefulness of these non-standard objects. Lecture 3 Thursday, June 22nd 10 am Title: Capacitary Sobolev Inequalities and Applications Abstract: The study of capacities and Capacitary Sobolev Inequalities is now more than half a century old, and yet there are still a number of open research questions to investigate concerning them. In this talk we discuss in more detail Capacitary Sobolev inequalities with an emphasis on a subject with the most recent activity - Capacitary Sobolev Inequalities around L1. Open problems will be mentioned.

Seminar

[Seminar] A kinase and a phosphatase: molecular basis of inherited Parkinson’s disease by Prof. Suzanne Pfeffer

Friday, June 23, 2023 - 10:00 to 11:00
C700, Lab 3

June 23, 2023 10:00 - 11: 00 at C700, Lab 3

Prof. Suzanne Pfeffer, Biochemistry at Stanford University School of Medicine

A kinase and a phosphatase: molecular basis of inherited Parkinson’s disease

Activating mutations in LRRK2 kinase cause Parkinson’s disease and activated LRRK2 phosphorylates a subset of Rab GTPases. We have discovered that Rab phosphorylation blocks primary cilia formation in specific neurons and astrocytes in the nigrostriatal circuit that are important for dopaminergic signaling in Parkinson's disease. This lecture will provide an update on our studies using purified LRRK2 and its counteracting PPM1H phosphatase to understand how the proteins become localized and activated on membrane surfaces. In addition, work will be presented related to the consequences of LRRK2 mutation for neurons and astrocytes in the dorsal striatum of mice and humans.

Research

Postponed to late July [Seminar] Natural analogues provide valuable insights on the potential mechanisms for fish adaptation and acclimation in the face of changing ocean conditions

Thursday, July 20, 2023 - 11:00 to 12:00
Lab4 L4E01 Seminar Room

Speaker: Dr. Davide Spatafora, Shimoda Marine Research Centre (SMRC), Tsukuba University, Shimoda City, Shizuoka, Japan

Hosted by: Professor Timothy Ravasi, OIST Marine Climate Change Unit

Abstract: Natural analogues are characterized by temporal and spatial environmental fluctuations and are home to pre-adapted ‘biodiversity’ (e.g., organisms chronically exposed to high CO 2 conditions). Therefore, these spots provide a unique opportunity to investigate the ability of the fish to acclimate or adapt to future ocean conditions thus informing us about how they may adjust in a future world.

Workshop

Integrability, Deformations and Chaos

Tuesday, July 25, 2023 - 10:00 to Thursday, July 27, 2023 - 17:00
OIST Seaside House, OIST Lab 4

In the last few decades, the notion of Integrable systems and Chaos, both classical and quantum, have seen immense developments. Fuelled by a flurry of scientific inter-community dialogues, these ideas have turned out to be universally useful in a wide spectrum of theoretical studies, from worldsheet string sigma models, to black holes and holography, and further into real experimental systems. Numerous interesting connections between these seemingly disparate research areas are developing, promising to shed light on important open questions. We hope to further fuel these dialogues by inviting people from different fields using state-of-the-art tools to explore these exciting ideas.
