Projects

Strain estimation for hazard forecastings before and after 2011 Japan Tohoku earthquake
ES7008 Geophysical Data Analysis, NTU
Analyzed seismic GPS displacement data in Python.
Estimated seismic strains with velocity fields using Delaunay triangulation.
Demonstrated correlations between earthquake event hotspots and strain hotspots, before and after Tohoku earthquake.

Variations in statistical complexity of genome sequences across species
CE7412 Computational and Systems Biology, NTU
Analyzed genome sequences of human, chimpanzee, rhesus macaque, dog, and fruit fly, from GenBank assembly in R.
Applied the Baum-Welch algorithm and Akaike information criterion to compute the average statistical complexity of their genomes.
Suggested that increased biological complexity corresponds to decreased statistical complexity in genomes.

Detecting adversarial attack of deep neural networks for image recognition from image complexity
PH3502 Chaotic Dynamical Systems, NTU
Trained image recognition deep neural networks with MNIST, Fashion-MNIST, and CIFAR10 datasets in Python.
Applied adversarial attacks such as Fast Gradient Sign Method (FGSM), DeepFool, One Pixel Attack, Jacobian-Based Saliency Map Attack (JSMA).
Showed that FGSM and DeepFool can be detected from its increased image complexity.

Monte Carlo photon transport in multi-layered biological tissues
PH4505 Computational Physics, NTU
Simulated photon transports in biological tissues by means of random walk in Python.
Demonstrated the applications of computational methods on medical areas such as biomedical imaging and photon therapy.

Monte Carlo simulation of periodic-driven Brownian particles
PAP723 Numerical Methods for Physicists, NTU
Simulated 2D toy model of attractive Brownian particles that obeys the Arrhenius equation for the formation and destruction of bonds.
Demonstrated that the system tends to configurations that result in increased entropy production when driven with a periodic driving force.

Designing, programming, 3D printing, and building a hovering quadcopter drone
Making and Tinkering Lite 1, NTU
Programmed a Arduino microcontroller.
Designed printed circuit board (PCB) in Autodesk EAGLE.
Designed and 3D printed drone in Autodesk Fusion360.
Simulated physical system in COMSOL Multiphysics.
