We are considering a radically different approach to binary reverse engineering tools by placing the recompilability as the first and topmost goal. We will further develop our preliminary study on Reassembleable Disassembling, with the similar design goal to preserve the recompilability while lifting the code to higher level languages or intermediate representations.   Learn more...

Transportation networks are part of our critical infrastructure. Location data from vehicles on these networks is important for making infrastructure policies, studying congestion, reducing pollution, real time routing, and providing value added services (e.g., Uber, Lyft). However, this location data could lead to inferring information that users might consider private such as their residential locations, health and economic status, and religious affiliation. Obfuscation mechanisms have been proposed as effective ways to protect the privacy of individual users while sharing their locations. However, users have limited control over the amount of privacy on their data as they have no easy way to interact with obfuscation mechanisms which are either too rigid (with their parameters) or too naive (with their assumptions) to be truly effective. In this seed project, we propose to develop a policy-based framework for adaptive location obfuscation. Our framework will provide users with strong privacy guarantees while effectively allowing them to balance the tradeoff between utility and privacy, depending upon their needs. Thus, it will improve security and privacy of data sharing in services and critical infrastructure such as traffic flow networks. Learn more...

Important decisions are increasingly automated, delegated to algorithms susceptible to bias and other flaws. In order to guard against problems associated with automated decisions, it is often suggested that there should be a “human-in-the-loop”—i.e., some form of human review—at least in the case of high stakes decisions. But human decision-making is susceptible to its own biases and flaws, as well as to external influence. Today this includes a range of automated influences, such as targeted advertising, recommender systems, AI assistants, and digital nudges. While existing discussions tend to frame questions about these decision processes in binary terms—automated or not—this project aims to understand the normative implications of increasingly blended forms of human-machine decision-making. What ethics and policy questions are raised by decision-making systems that benefit from the strengths of both human and machine deciders, but also are subject to the weaknesses of each? How can ethics and policy guide a world in which individually and socially important decisions are reached by blended human-machine deciders? Learn more...

The United States produces more than 938 million pounds of mushrooms annually valued at $1.2 billion, with Pennsylvania producing 66% of the total US mushroom crop (USDA NASS, 2020). Mushroom production is a very labor-intensive process. The Pennsylvania Farm Bureau and Sexsmith (2019) studies report a critical shortage of farm labor in Pennsylvania, and the US mushroom farms are short by 20% of the number of workers needed on their farms to complete required tasks, thereby limiting the crop yield and economic outcomes. This project will address the labor shortage in three ways: (1) develop automated fresh mushroom harvesting and packaging technologies through smart agriculture; (2) modify crop management techniques to optimize harvesting rates of manual laborers and mechanized systems; and (3) provide advanced technologies to industry stakeholders for labor efficient production and the economic well-being of rural communities.

In this project, we will build an IDE tool for visualizing the lifetime scope of a user-selected Rust variable. We believe our tool can help Rust programmers avoid deadlocks at the development stage. After writing a piece of code involving a mutex, a programmer can select the return value of a locking operation or the locking operation itself (when the return is not saved to a variable). Our tool will visualize the lifetime scope of the return value (i.e., the critical section). The programmer can then inspect whether the end of the critical section is expected. In addition, our tool will conduct deadlock detection for the selected critical section and provide detailed debugging information for identified bugs, such as highlighting blocking operations or function calls leading to blocking operations.

This project will address a critical barrier to the financial and environmental viability of plastic chemical recycling: an inability to design and operate efficient processes that reliably achieve target material, energy, and emissions benefits despite geo-temporal variation of composition and quality of plastic streams. This barrier stems from a lack of mechanistic understanding of the process components. We will develop a mechanistic understanding of sequential fast pyrolysis and catalytic upgrading of a mixture of polyester, i.e. polyethylene terephthalate (PET), and polyolefin, i.e. polypropylene (PP), to valuable chemicals. The mechanistic understanding gained in this work will allow the development of microkinetic reaction models, which can be incorporated into reactor simulations for process optimization and translate the knowledge obtained in the laboratory to the manufacturing industry. Our team will utilize experiments, data science and theory to overcome fundamental science and engineering challenges in mixed plastic upcycling. Learn more...

The research involves the development of new experimental technologies to investigate RNA structures one molecule at a time and new computational technologies of artificial intelligence wherein a computer learns patterns that can predict RNA structure and its variation. Using rice (Oryza sativa) as the primary model system, the proposed research will develop new wet bench and computational approaches that will allow categorization of the mRNA “pan-structurome,” its consequent impacts on gene expression, and its functional association with respect to local climate conditions in rice landraces. Training will be provided to postdoctoral fellows, graduate students, undergraduates, and high school students and teachers. Broader Impacts will include development of the Oryza CLIMtools webtool to relate rice genotypes with climate variables and to identify beneficial structural haplotypes for use in development of elite rice cultivars. Impact will be broadened through technology including enhanced browser-based RNA structure-reactivity visualization and publicly available instructional screencasts. Learn more...

We propose a novel, adaptive, and general framework for federate semi-supervised learning, which is a new research paradigm aiming to exploit the power of unlabeled data ignored by existing federated supervised learning. Introducing unlabeled data to federated learning brings several new challenges, which limits the applicability of existing models. In this proposal, we define the federated semi-supervised learning problem from the insight of data regularization and analyze the new-raised difficulties. This project creates new fundamental knowledge in both federated learning and semisupervised learning fields and will significantly advance these two fields by developing novel methods and implementing analytic tools.

In high stakes applications of machine learning, the ability to explain the machine learned model is a prerequisite for establishing trust in the model’s predictions. Satisfactory explanations have to provide answers to questions such as: "What features of the input are responsible for the predictions?"; "Why are the model’s outputs different for two individuals?" (e.g., Why did John’s loan application get approved when Sarah’s was not?). Hence, satisfactory explanations have to be fundamentally causal in nature. This project will develop a theoretically sound, yet practical approach to causal attribution, that is, apportioning the responsibility for a black-box predictive model’s outputs among the model’s inputs.

The goal of the proposed research is to develop proactive approaches for handling systemic biases in machine learning datasets by tackling the following question: Can we build better crowdsourcing systems which are robust to handling subjective biases of human crowd-workers such that datasets derived from such systems are bias-free (thereby leading to unbiased ML models)? In other words, we propose to build robust crowdsourcing systems which can ensure that they generate datasets which are bias-free at the time of creation. As a result, ML algorithms trained in the future (on such datasets) do not have to worry about bias in their training. More specifically, we propose to achieve this goal by designing optimal ways of incentivizing (or dissuading) human crowd-workers so that it is in their best interests (from a utilitarian perspective) to not let their personal biases affect their annotation process, thereby resulting in bias-free data.

This project seeks to develop the next generation screen magnifier that will bridge the wide gap in smartphone user experience for people with low-vision impairments. It is rooted on three novel ideas. First, instead of indiscriminately magnifying the screen content as is done now, it will do object-aware magnification by identifying the objects in the graphical interface and compacting the space between the objects so as to keep contextually related objects close together in the magnified view. Second, by leveraging the untapped built-in sensors such as accelerometer, geometric field and barometric pressure sensors, it will expand the default surface gestures to include surfaceless natural gestures for magnification operations that can be done with only one hand, thus freeing the other hand for other tasks. Third, it will incorporate a novel keyboardless gesture-based text entry and editing technique to eliminate the difficulties that arise with virtual keyboards for text entry in magnification mode.

The goal of the research team is to develop a convergent device platform that can rapidly capture, sense, and identify viruses and predict new antigenic strains against which the human population has limited or no immunity. The project pursues a solution to a grand challenge in the surveillance and characterization of circulating epidemic and pandemic influenza virus strains by addressing deep scientific questions in enhanced Raman spectroscopy for virus detection and evolution prediction. The proposed platform is based on controlled virology experiments that propagate by culture and mutate viruses for specific research tasks, a novel virus enrichment platform for effectively capturing viruses without labels, biosensing of virus surface proteins with enhanced signal through a novel 2D/metal enhanced Raman spectroscopy technique, and rapid and sensitive virus identification and evolution prediction through machine learning analysis of enhanced Raman data.
