PhD research

My PhD focuses on Topological Data Analysis and Topological Deep Learning Applied to Physical Systems Across Scales. The central goal is to identify topological summaries that are not only statistically useful, but can also be related to physical mechanisms, observables, and changes of regime.

Current thesis projects

Three projects currently form the main multiscale backbone of my thesis, each asking how persistent topology can encode physically meaningful structure in a different class of data.

Astronomical scale Current

TopoAGN

Topological observables of AGN variability

Multiband light curves of active galactic nuclei are studied through classical variability diagnostics, delay-space geometry, persistent homology, and multiscale statistics to characterize structure that is difficult to capture with single summary statistics.

AGN Time series Multiband TDA
Mesoscopic scale Current

MasterMaze

Topology and geometry of behavioral learning

Movement trajectories from maze-learning and reversal tasks are analyzed using behavioral metrics, trajectory geometry, networks, information-theoretic quantities, and topological summaries to study how spatial organization changes during learning.

TopoDOS

Persistent topology of quasiperiodic spectra

Persistent homology is applied to density-of-states representations of quasiperiodic systems and BCN monolayers, with emphasis on the relation between finite persistence features, spectral gaps, scaling, and physically interpretable spectral structure.

Broader research topics

Beyond the three thesis anchors, I work on or actively explore the following directions across astrophysics, nonlinear dynamics, fluid and plasma physics, behavioral data, and condensed matter.

Active galactic nuclei and host galaxies.

Active Galactic Nuclei

Topological, geometric, and multiscale descriptors of AGN variability and host-galaxy structure, with the goal of connecting morphology and temporal behavior to nuclear activity.

Mosaic of galaxies with different morphologies.

Galaxy Morphology

Persistent homology and representation learning for robust, interpretable descriptors of galaxy images, including unsupervised and self-supervised approaches.

Time series representation of gravitational-wave-like data.

Gravitational-Wave Detection

Topological summaries of noisy gravitational-wave-like time series across signal-to-noise regimes, including sensitivity to physical parameters and robustness to noise.

Asteroseismology

Topological representations of oscillation spectra and stellar variability, seeking links between mode structure, stellar parameters, and multiscale geometric organization.

Dynamical & Complex Systems

Delay embeddings, persistent homology, Mapper, and recurrence methods for nonlinear dynamics, attractors, transitions, and higher-order organization.

Statistical, geometric, network, and topological analysis of movement patterns during learning tasks, with emphasis on spatial strategies and behavioral transitions.

(Magneto)hydrodynamics

TDA and scientific machine learning for shocks, vortices, reconnection, turbulence, and the validation of data-driven predictors for fluid and plasma dynamics.

Experimental signal illustrating Barkhausen noise.

Barkhausen Noise & Disordered Media

Persistent topology of avalanche-like signals and disordered systems, connecting homological signatures with statistics, criticality, and domain-wall dynamics.

Phase Transitions

Topological and Morse-theoretic approaches to changes of regime in lattice and statistical-mechanical models, with attention to critical behavior and order-parameter structure.

Across physical scales

The recurring question is the same: which geometric or topological structures survive changes of representation, noise, resolution, and physical scale—and what do they mean physically?

Astronomical

Signals, spectra & images

AGN variability, stellar oscillations, galaxy morphology, gravitational-wave-like signals, and related inverse problems in astrophysics.

Mesoscopic

Dynamics, flows & behavior

Nonlinear trajectories, learning dynamics, shocks, vortices, fluid and plasma simulations, and topology-aware diagnostics for scientific machine learning.

Microscopic

Spectra, disorder & criticality

Quasiperiodic spectra, density of states, Barkhausen noise, disordered media, phase transitions, and topological structure in microscopic models.
