Prof. Nick Feamster, 310 Sherrerd Hall

  • Research Areas: Networking, Security, Anti-Censorship
  • I am generally interested in topics that improve the performance and accessibility of the Internet and its applications. My interests range from network management and and security (the things that make the network "work", including topics like software defined networking) to Internet censorship and control to performance measurement (especially in far-flung regions of the world, such as developing regions). The type of work I do is general systems-based, empirical, and data-driven; much of the research projects described below involve collection and analysis of large-scale network data (including applications of statistical machine learning), as well as the design and implementation of the systems to support this data collection, analysis, and inference.

Below are some broad areas where I am currently working and have specific project ideas. I generally find that undergraduate research works best if students select a problem from the topic list below; this allows me to devote more attention to your project, and also to couple you with other students who are working on related problems, thus allowing you to take advantage of a broader knowledge base than just me.

  • Performance measurement of broadband and mobile access networks. As broadband Internet access becomes more pervasive, understanding the performance that end users receive---and how they use he available capacity---is more important than ever. Towards this goal, I work on technologies to characterize and improve the performance of fixed and mobile broadband access networks. My group develops software to perform these measurements, including BISmark (for home routers, Raspberry Pis, etc.) and My Speed Test (for Android), and I am very interested in working with students who want to gain experience developing tools and systems for these environments or with analyzing data collected from these settings. Below are some possible project ideas:
    • Understanding Mobile Data Performance and Usage. For approximately two years, we have been collecting data from a relatively large deployment of a mobile phone application that we developed called MySpeed Test, which is available in the Google App Store ( At its peak, the tool had about 5,000 users in more than 30 countries. Currently, the tool has about 1,000 installed versions running. The tool collects a variety of data, both about network performance and about network usage. For example, the tool collects information about the throughput and latency that a mobile device experiences to different network destinations (e.g., Google, Facebook). In addition to the performance data, the tool also gathers data about user behavior—such as how much data each application on the phone consumes, how often they use each application, and so forth. Finally, the application collects metadata, such as the devices physical location, remaining battery life, billing cycle, and other environmental characteristics. We envision a variety of possible data analysis exercises that students could perform using this dataset. The dataset has such a rich set of features and many analysis questions are possible. One possible starting point would be to ask how user behavior correlates with the network performance, the amount of data they have used in their billing cycle, time of day, the type of device they have, and so forth.
    • Pinpointing locations of congestion (e.g., Comcast/Netflix). Current events have highlighted the ongoing congestion episodes on the wide-area Internet, with consumers continually complaining of poor performance for various applications and Internet destinations. Yet, despite widespread attention in industry and popular media, we lack accurate methods for pinpointing congestion locations. We could use distributed measurement frameworks such as BISmark, MySpeedTest, and others (e.g., RIPE Atlas) to try to get more accurate characterizations of the locations of Internet congestion. See this (flawed) report for a starting point on a problem statement; we can probably do better.
    • Home network performance troubleshooting. We have developed initial algorithms to determine whether a performance bottleneck is caused by a user's home wireless network or by the portion of the path on the wide area Internet. These algorithms can be deployed on the BISmark home router devices and placed in user homes to study the contribution of users' home wireless networks to various network and application problems.
    • Performance measurement and characterization of emerging technologies. I would like to use our existing measurement platforms (i.e., BISmark, MySpeedTest) to design measurement tools that characterize various ISPs' support for emerging technologies, such as DNSSEC and IPv6?
  • Censorship measurement and circumvention. More than 60 countries around the world implement some form of Internet censorship. We are developing techniques to better understand these practices and ultimately to assist citizens with circumventing these controls. Along these lines, two possible project areas involve (1) analyzing measurements of Internet censorship that we have collected (or collecting new ones); (2) better understanding the capabilities and limitations of existing circumvention tools; (3) designing new approaches for circumvention. A few possibilities are below.
    • Measuring Internet censorship. What is the current state of Internet censorship and how can we fight it? We are interested in who is censoring the Internet, what they are blocking access to, and how they are restricting access. In answering these questions, you could work on anything from developing ways to get around censorship to helping NGOs around the world advocate against censorship.
    • Analysis of censorship measurements. We have collected extensive measurements of Internet censorship and manipulation using a tool called Encore. It would be interesting to analyze the data on Web filtering that we have been gathering for more than a year, with the goal of identifying both broader patterns across different regions and countries and across time.
    • Extensions to ExitMap. ExitMap is a tool for characterizing properties of Tor exit relays across the Internet. The tool was written by Philipp Winter, who is now a researcher at Princeton and is an active Tor developer. Projects involving Exitmap will give you a chance to interact directly with a Tor developer!
      • Add new scanning modules. For example, add a module that searches for arbitrary keywords, crawls the web, and compares Tor and not-Tor traffic. Or, add a module that looks for exit relays performing traffic monitoring.
      • Add code that makes it possible that exitmap runs autonomously in the background and periodically fetches new server descriptor: <>
  • Software-defined networking (SDN). Briefly, SDN makes it possible to control the behavior of the network from a single high-level program (e.g., a Python or Java program). This paradigm opens up many new possibilities, since controlling the network becomes a software development problem, rather than one that is constrained by low-level, vendor-specific, proprietary interfaces. I'm interested in two areas of SDN:
    • Applications of SDN to Wide-Area Networking. We are developing an SDN controller and working to deploy this in some of the world's largest Internet Exchange Points (IXPs), with the hopes of changing how Internet service providers (e.g., Comcast, Netflix) exchange traffic. The flexibility that SDN provides makes it possible to improve security, enable more flexible interconnection policies, automate traffic management, and so forth. There are many different possibilities for working in this area. Here are some project ideas.
    • Fast, scalable, and accurate inference algorithms that can provide input to network control systems. Kinetic is one such system that we have built in the past that integrates event stream processing with network control, to solve problems with dynamic control such as authentication and intrusion detection. We are beginning to explore how stream processing engines such as Kafka and Storm can be used to process network event streams, how scalable machine learning can be applied to network inference, and how the output from these algorithms can be used to enable networks that are self-tuning.
  • Internet of Things (IoT) security. The increasing number and diversity of consumer electronics devices that are connected to the Internet introduces a grave security threat, since many of these devices are what I would call "fundamentally insecure". Given that we are likely to have a large number of insecure devices connected to the network that cannot be patched, we need new capabilities in the network that ensure both the security of these devices and the privacy of their users. Some possible sub-problems include:
    • Device fingerprinting. By analyzing the traffic patterns from devices on the network, determine what types of devices are connected to the network? (For example, can you automatically identify a thermostat, photo frame, etc. based on network traffic patterns?)
    • Anomaly detection. Develop algorithms that can detect when an IoT device is deviating from normal behavior. Incorporate these algorithms into a "network firewall" that can automatically detect and mitigate anomalous or attack traffic.

    1. Investigate the most efficient way to deliver packets to an array of low-cost Wi-Fi APs strung along the ceiling of a tunnel so that they may deliver those data to customers aboard a metro train speeding through the tunnel below.
    2. Faster-than-Nyquist is a technique in the wireless physical layer that allows packets to be decoded when their transmissions are speeded up in a certain way. Can you think of interesting ways of leveraging this at higher layers of the networking stack, for example the way it might interact with Wi-Fi’s link-layer frame aggregation functions?

First step: identify the technology and usage/engagement metrics you might be interested in studying. You will write code that collects and analyzes this data.
    2. Help me build tools for computer science education at Princeton and beyond. I taught high school computer science for many years and if you took any computer science at the high school level, you know that the tools available to teachers are relatively primitive. Princeton has a few internal tools developed for COS 126 that would be great to make available to high school students or to other colleges students such as the Java Visualizer and Websheets. You are not limited to these existing tools; propose a tool that might be useful to students and we'll try to make it work!

  • I am also coordinating the development of new grading and assessment infrastructure at Princeton, that will eventually be open-source and deployed at other universities. These projects focus on automation, using various techniques - such as OCR or OMR -, smart heuristics, and creative UI design, to streamline most tasks associated with a university. The goal is to be more efficient, to collect more data, and to better understand what makes a good course. You would have the opportunity to contribute to something that will be used at Princeton's CS department (of which the intro course has the highest enrollment on campus) and beyond for years to come. Here are some example projects:
    1. Design/improve an OMR (Optical Mark Recognition) project that is currently being deployed for the computer assisted grading of exams.
    2. Integrate handwritten character recognition to the OMR component.
    3. Analyze large quantities of secondary data collected (for example, do students that do the programming assignments in pairs do better in the course or not? how many hours in COS Lab are helpful on average, and when do we hit a point of diminishing returns).
    4. Design heuristics and interfaces to spot students in difficulty much earlier in the term, when there is some hope of helping them.
    5. Extend the COS Lab Queue so it may be used out of the box in all labs accross campus.
    6. Develop a robust testing infrastructure using virtual machines, secure threads, and intelligent feedback to supplant the run-script system currently used.
    7. Develop an interface to make grading of assignment done online.
    8. Integrate hardware solutions (cardswipe, barcode scanning, etc.) to many of these tools to make them even more frictionless.
    9. Some related crowd-sourcing projects...
  • A lot of these projects can include some Big Data component, and involve analyzing data and drawing some observations from it.
  • Finally, I am always up for any ambitious coding project, or survey project in preparation (or not) to an undergrad thesis.

Dr. Arvind Narayanan 308 Sherrerd Hall

Research areas: broadly, privacy and security. Especially online tracking and Bitcoin.

Some topics and questions I'm interested in:

1. What can be inferred about people based on publicly available online data?

If someone really wanted to find out personal things about you online, how far could they get? Let's investigate this by writing a bot which, given an identity (say, an email address), collects and aggregates information from various sites about that person. Ideally, it should be able to automatically figure out which information is current and which is out of date, reconcile conflicts, make new inferences based on multiple pieces of data, and hook into the "deep web" — pages that are not directly visible on web searches.

2. Reverse engineering the Web to expose poor security and privacy

Web companies track us online and compile extensive databases of our personal information. The personal behavioral profiles created through tracking are used for targeted advertising, price discrimination, targeted political emails, and various other practices that make people uncomfortable. I have an ongoing long-term project to automatically reverse engineer web trackers to determine what information companies have collected about you and what they are using it for. There are many interesting sub-projects to work on.

3. Various Bitcoin-related projects

Can we make a more secure Bitcoin wallet? Just how anonymous are Bitcoin users? Can we create an "early-warning system" that connects to a large number of P2P Bitcoin nodes and looks for signs of possible attacks on the security or stability of the system? What applications can we build on top of block chain technology?

Opportunities outside the department

We encourage students to look in to doing interdisciplinary computer science research and to work with professors in departments other than computer science. However, every CS independent work project must have a strong computer science element (even if it has other scientific or artistic elements as well.) To do a project with an advisor outside of computer science you must have permission of the department. This can be accomplished by having a second co-advisor within the computer science department or by contacting the independent work supervisor about the project and having he or she sign the independent work proposal form.

Here is a list of professors outside the computer science department who are eager to work with computer science undergraduates.

Prof. Mung Chiang, B238, E Quad.

    4. Network Science
  • Ideas for Independent Research Topics:
    1. Internet security and privacy: The insecurity of Internet protocols and services threatens the safety of our critical network infrastructure and billions of end users. How can we defend end users as well as our critical network infrastructure from attacks?
    2. Trustworthy social systems: Online social networks (OSNs) such as Facebook, Google+, and Twitter have revolutionized the way our society communicates. How can we leverage social connections between users to design the next generation of communication systems?
    3. Privacy Technologies: Privacy on the Internet is eroding rapidly, with businesses and governments mining sensitive user information. How can we protect the privacy of our online communications? The Tor project ( is a potential application of interest.

Janet Vertesi, Sociology Dept, Wallace Hall 122

  • Research areas: Sociology of Technology; Human-Computer Interaction (qualitative); Informatics and Information Science; Computer-Supported Cooperative Work; Ubiquitous and Urban Computing.
  • About this research: Human-Computer Interaction is an exciting and expanding community of computer scientists, anthropologists, sociologists, and critical theorists who examine computing "in the wild" and are dramatically changing our sense of the possibilities of human technological experience. My research takes place at the intersection of sociology and computer science, and uses qualitative methods to build new software and hardware tools supporting a wider range of technological experiences. To learn more, visit my website:
  • Independent Research topics:
  • 1. Seeking a student to help build an Evernote plug-in to support group qualitative research. Must be ready to engage with not only technical specifications but also to think about critical theory, feminist theory, and ethnographic sensibilities.
  • 2. Got an idea for a project on computing in the developing world? or urban infrastructures? Or mixed-reality gaming? Let me know. I'm always looking out for interesting way to use qualitative research methods to better understand how users "in the wild" appropriate technologies into their daily lives, and using those insights to inform the design of new technological systems and possibilities.
