Professional Experiences

Worked as a research assistant in Dr. Sung's lab under Professor Andrew H. Sung, Ph.D., and do my research in Applied Cybersecurity, Machine Learning, Deep Learning, and Computer Vision. In addition, as a TA, Taught and Graded courses: Computer Networks, Data Structures, Computer Systems, Project Management, and Computer Science II (C++ Programming).


Responsibilities:

  1. Conducted in-depth research into two cybersecurity topics: Mobile malware detection and Deepfake (aka. Fake image/video) detection directed by the professor.

  2. Conducted experimental tests and developed new research methods for these two topics.

  3. Developed and implemented quality control procedures for research methodology.

  4. Prepare detailed reports playing out various scenarios for research purposes.

  5. Prepare reports on research methodology and conclusions.

  6. Performed set-up and preparation procedures as required by the professor.

  8. Prepared and maintained laboratory equipment prior to and after work.

  9. Guided/Assisted an MS research project of 7 Master's students for five months (Spring 2018).


Key achievement (in research):

  1. Introduced a new feature selection method for Android malware detection.

  2. Introduced real-time malware scanner using Ethereum Blockchain technology.

  3. Introduced deep learning (DL)-based technique for fake image/video (aka. Deepfake) detection.

  4. Though the DL-based approach can achieve good solutions, introduced the results of a new study indicate that traditional machine learning (ML) techniques alone can obtain superior performance in detecting Deepfake

  5. Performed a systematic literature review of 112 studies on Deepfake detection.

  6. Created a new and more diverse Deepfake dataset (will be published soon).

      8. Delivered higher-level undergraduate and graduate courses via classroom, online and hybrid methodologies to satisfy course curricula and meet student needs.

      9. Monitored student use of learning tools and equipment for safe and effective handling.

      10. Created a positive and safe learning environment for students by setting and enforcing the classroom code of conduct.

      11. Impartially evaluated papers, projects, and homework assignments of students, delegating grading to teaching assistants when appropriate.

      12. Evaluated and supervised student activities and performance levels to provide reports on academic progress.

      13. Contributed to planning appropriate and engaging lessons for both classroom and distance learning applications.

      14. Applied innovative teaching methods to encourage student learning objectives.

      15. Graded over 80-90 assignments per week and entered grades into the school’s recommended software application (e.g., Google classroom, model, Canvas, etc.) and the school’s ERP system.

      16. Identified student strengths and weaknesses to create tailored learning activities, including career goal setting and concepts on future upcoming technologies activities.

      17. Created lesson plans for courses, modifying them throughout the year to meet time constraints and specific interests of the class.

      18. Conducted engaging in-class discussions to facilitate learning and encourage participation.

      19. Worked closely with the course coordinator to develop and implement a computer science curriculum for improved learning and student performance.


Key achievement:

  1. Published a total of 6 papers: 2 in image processing, 2 in computer vision, and 2 in e-learning.

  2. Received Researcher Award for two consecutive years (2017 and 2018).
