Functional principal component analysis (FPCA) on remote sensing data and longitudinal studies
This dissertation consists of three main pieces of my Ph.D. dissertation, which shapes my research on multivariate functional data, change-point detection, asynchronous longitudinal data, and remote sensing data applications. The first project is motivated by NASA's first dedicated \ce{CO2} monitoring satellite, the Orbiting Carbon Observatory-2 (OCO-2)

Exploring the Single-Cell Dynamics of FOXM1 Under Cell Cycle Perturbations. [PDF]
The varied FOXM1 dynamic patterns reveal significant differences in cellular responses to the same stimuli at the single‐cell level. This emphasises the relationship between cue, signal and response as influenced by different drug types and concentrations.

Unvealing the Principal Modes of Human Upper Limb Movements through Functional Analysis
The rich variety of human upper limb movements requires an extraordinary coordination of different joints according to specific spatio-temporal patterns. However, unvealing these motor schemes is a challenging task.

On the prediction of stationary functional time series [PDF]
This paper addresses the prediction of stationary functional time series. Existing contributions to this problem have largely focused on the special case of first-order functional autoregressive processes because of their technical tractability and the ...

High-Dimensional Multiresponse Partially Functional Linear Regression. [PDF]
ABSTRACT We propose a new class of high‐dimensional multiresponse partially functional linear regressions (MR‐PFLRs) to investigate the relationship between scalar responses and a set of explanatory variables, which include both functional and scalar types.

Recognition and Characterization of Forest Plant Communities through Remote-Sensing NDVI Time Series
Phytosociology is a reference method to classify vegetation that relies on field data. Its classification in hierarchical vegetation units, from plant associations to class level, hierarchically reflects the floristic similarity between different sites ...

Functional factor analysis for periodic remote sensing data [PDF]
We present a new approach to factor rotation for functional data. This is achieved by rotating the functional principal components toward a predefined space of periodic functions designed to decompose the total variation into components that are nearly ...
