Selected Publications

Within the framework of functional data analysis, we develop principal component analysis for periodically correlated time series of functions.
in progress, 2017.

Orchestration load is the effort a teacher spends in coordinating multiple activities and learning processes. It has been proposed as a construct to evaluate the usability of learning technologies at the classroom level, in the same way that cognitive load is used as a measure of usability at the individual level.
IEEE Transactions on Learning Technologies, 2017.

In this paper, we address the problem of dimension reduction for time series of functional data ($X_t$: $t$ ∈ $Z$). Such functional time series frequently arise, e.g., when a continuous-time process is segmented into some smaller natural units, such as days.
In JRSSB, 2015.

For MOOC learners, lecture video viewing is the central learning activity. This paper reports a large-scale analysis of in-video interactions.
Design for teaching and learning in a networked world, 2015.

We study estimation and prediction in linear models where the response and the regressor variable both take values in some Hilbert space.
Scandinavian journal of statistics, 2015.
