YTD Highlights

About Me

I am a PhD Candidate in the Computer Science Department at Virginia Tech. My research sits at the crossroads of Human Computer Interaction and Security - formally Human Factors in Cybersecurity and revolve around mobile phones. I look at how users perceive risk, if current systems designed to help people mitigate risks are effective in achieving this, and creating new frameworks that would aid users in making informed decisions about risk. I am advised by Dr. Scott McCrickard .


I graduated from Georgia Southern University with a degree in Computer Science. My undergraduate honors thesis dealt with wireless network security and was advised by the late Dr. Ardian Greca and Dr. Wenjia Li. I received my Master's degree from Norfolk State University in 2016 - where my research was focused on Cybersecurity. I was a Research Assistant in Dr. George Hsieh's lab, and my thesis was advised by Dr. Luay A. Wahsheh.

Ongoing Projects

  • Technology on the Trail

    We consider who trail users are, what technologies they use (how and why) and most importantly, what the dynamic between different groups are on the use of technology are. For example, Hunters agree on the notion of fair chase, but disagree on how this works in practice depending on weapon preference. We find that there are opportunities for research and design in the tension (or conflict) between groups.

      Progress:
    • Sep. 2018: We will be presenting our Paper on groups and community tensions on the trail at the Rural Computing Workshop at CSCW 2018 (arXiv).
    • Aug. 2018: Paper on Museum technology has been accepted to AFRICHI conference to be held in Windhoek, in December
    • Apr. 2018: The Gardenator: Fostering Learning by Improving Attitudes Towards Science. In conjunction with the Science Museum of Western Virginia (SMWV).
      • We've built the Android application
      • Initial user study has been conducted
      • This project was awarded first place in both the Marston Award for most enterpreneurial project and the Capstone award for best capstone (for undergraduate co-researchers: Ann Hoang, Havisha Panda and Jennifer Shenk) at the VTURCS Spring 2018 Symposium!
    • Feb. 2018: Paper on Opportunities for research submitted for CHI Outdoors Workshop. [arXiv]
    • Jan. 2018: Paper on Who is on the trail presented at Technology on the Trail Workshop at ACM GROUP
  • Patterns in Application Maintenance

    We scrape application update logs from four major application stores: Google PlayStore, Apple AppStore, Windows Store and Blackberry World, and also scrape timeline information for these apps from the WayBack Machine. From this data, we attempt to observe patterns in how applications are updated, what makes an application successful, predict the future of the different stores, and create useful models that would make it easy for developer to implement strategies.

      Progress:
    • Initial paper in draft stages
    • Weekly data collection of application update data is ongoing
  • (Un)Informed Consent

    How useful are privacy policy documents that accompany mobile applications? How do we measure this usefulness? We approach this question by examining privacy policy documents provided by 107,000 applications from the Google PlayStore.

      Progress:
    • Revisions based on inital feedback is ongoing.

Service

Virginia Tech Early Engineering Mentoring (VTEEM) Graduate Mentor 2018

  • VTEEM is a program that assists incoming first year students with their graduate college transition by providing positive academic, professional, and social environments outside of the classroom. As a VTEEM mentor, I was nominated, selected and trained to offer academic advice and guidance to incoming students while providing my own student perspective on the College of Engineering experience.

Tech Girls Mentor/Graduate Assistant: 2017, 2018

  • TechGirls is an international summer exchange program designed to empower and inspire young girls from the Middle East and North Africa (Algeria, Egypt, Jordan, Lebanon, Libya, Morocco, Palestinian Territories, Tunisia, and Yemen) to pursue careers in science and technology. Through a collaboration of the Bureau of Educational and Cultural Affairs at the U.S. Department of State and Legacy International, we host TechGirls for a week of coding and mentoring at Virginia Tech encompassing logic, basic application design and in-depth Java programming sessions.

Cyber Security Summer Internship Program: Graduate Mentor 2016

  • The Cyber Security Summer Internship Program was sponsored by the Department of Defense's (DoD) Center for Excellence in Cyber Security and the Department of Energy's National Nuclear Security Administration (NNSA) Consortium for K-20 Cyber Security Workforce Pipeline, who funded a selection of underrepresented minorities from undergraduate programs at different universities in the U.S. for a summer-long intensive training on Cyber Security (attack, defense and analysis) at Norfolk State University.
