・The 1st TUS Geometry & Natural Science
Speaker: Masayuki Sakurai（Tokyo University of Science）
Title: Reading Life through Shape: The Biology of Nucleic Acid Structure
Date: June 14, 2025
Place: Tokyo University of Science, Kagurazaka Campus, Room 222
Abstract: DNA and RNA function not merely as linear sequences, but
as structured molecules whose shapes are key to their roles. In this talk,
I explore how the structure of RNA?especially transfer RNA?enables biological
function, and how structural variation is compensated through chemical
modifications or protein support. I also highlight adenosine-to-inosine
(A-to-I) RNA editing as a process in which structural irregularities are
recognized and corrected, effectively altering RNA "meaning."
Finally, I introduce technologies for detecting and directing RNA editing,
offering a new view into how life can be understood?and controlled?through
molecular geometry.

・The 3-th TUS Geometry & Natural Science
Speaker: Akinori Yamanaka（Tokyo University of Agriculture and Technology）
Title: Integration of Phase-Field Simulation of Microstructural Evolution
with In-situ Observation using Bayesian Data Assimilation
Date: July 26, 2025
Place: Tokyo University of Science, Kagurazaka Campus (Room: in adjustment)
Abstract: The phase-field method is an effective numerical modeling and simulation approach for microstructural evolution (e.g., grain growth, grain boundary migration, and phase transformation). To improve the predictive accuracy of phase-field simulations, the parameters in the model must be accurately calibrated using experimental data. In this presentation, I will introduce an approach that integrates in-situ experimental observations with phase-field simulations through data assimilation based on Bayes’ theorem, enabling precise parameter estimation.
