Recorded 24 February 2026. Smita Krishnaswamy of Yale University presents "Inferring Dynamic Cellular Trajectories and Underlying Cellular Regulatory Networks with Neural and Graph ODE Models, Pt. 1/2" at IPAM's Mathematics of Cancer: Open Mathematical Problems Workshop.
Abstract: This two-part tutorial. The first part will cover our data diffusion geometry-preserving PHATE method for embedding cellular data into a low dimensional state space, and then to infer cellular trajectories within that space using our biologically principled neural ODE framework called MIOflow (manifold interpolating flows). In the second part, we will cover our graph ODE framework called RITINI (Regulatory Interaction Network Inference) to infer regulatory mechanisms underlying these dynamic cellular trajectories. We will also cover a case study in breast cancer, showing how cells transform from cancer stem cell states to aggressive metastatic states, and how these methods could be used to discover potential state-gating targets.

Recorded 05 May 2026. Takeo Hoshi of the National Institute for Fusion presents General data-analysis framework ODAT-SE and its applications at IPAMs Fusion Device Design and Engineering Workshop.
Abstract: This talk first provides an overview of our project, “Backcasting Digital Systems by Super-Dimensional State Engineering” [1,2], which is part of the Moonshot R&D Program Goal 10 (MS10): “Realization of a dynamic society in harmony with the global environment and free from resource constraints through diverse applications of fusion energy by 2050” [3]. This program is a Japanese flagship initiative for fusion energy. Our project was launched at the end of 2024 as an interdisciplinary effort bridging the fusion energy field with other domains, including AI and data-driven science, simulation science, applied mathematics, and high-performance computing (HPC). The project aims to develop digital systems for the design of fusion devices, particularly tokamak and helical types, as well as for related materials experiments. This talk then introduces our data analysis framework, ODAT-SE (Open Data-analysis Tool for Science and Engineering, pronounced oh-daht ess-ee)[4]. ODAT-SE enables a variety of analysis methods, including parallelized Monte Carlo methods for Bayesian inference and parallelized Bayesian optimization. These methods are designed to run efficiently on both small-scale PCs and massively parallel supercomputers. This talk gives several preliminary results by ODAT-SE.
