Chawin Sitawarin

Hello there!

I am a senior undergraduate student in Electrical Engineering Department at Princeton University. I am from Bangkok, Thailand. My name in Thai is "ชวิน สีตวาริน".

Currently, I am broadly interested in the fields of machine learning and computer security. I have worked on multiple research projects with Prof. Prateek Mittal, and my senior thesis advisor is Prof. Peter Ramadge. I also used to work on photonics with Prof. Alejandro Rodriguez.

GAN and Adversarial Examples

Senior thesis advised by Prof. Ramadge (2017 - Present)

We aim to explore and model the distribution of adversarial examples in the input space as well as construct novel attacks and defenses using variations of GAN

Physical Attacks on Traffic Sign Recognition Systems

C. Sitawarin, A. N. Bhagoji, A. Mosenia, M. Chiang, P. Mittal (2017 - Present) [paper] [code]

We propose a range of real-world attacks against traffic sign recognition and detection systems of self-driving cars as well as possible defenses. We improve one existing attack based on adversarial examples and propose two novel attacks. Learn more

Practical Attack on Traffic Sign Recognition Systems

Junior independent work advised by Prof. Mittal (2016 - 2017) [report] [poster]

We construct practical adversarial examples for traffic sign classifiers and evaluate them under different lighting conditions and perspective transformations.

Defense Against PDF Malware Detector Evasion

Seminar project advised by Prof. Mittal (2016) [report] [presentation]

We survey several evasion attacks on PDF malware detectors that rely on ML classifiers. Our experiment aims to find robust ML classifiers against such attacks and possible defenses including dimensionality reduction and adversarial training.


Summer Research Intern

Hong Kong Applied Science and Technology Research Institute (ASTRI) Hong Kong (Summer 2016)

I was a summer intern at ASTRI and a part of IC Digital Design team. My team focused on implementing a real-time super-resolution CNN on an FPGA. My work involved transferring the module written in C and Matlab and implementing it in RTL using Vivado High-Level Synthesis tool.
