New Models in Online Science Journalism

A sense of urgency has emerged in the last decade about the future of science journalism. While it is often argued as an important source of information for non-specialists, science journalism has been heavily criticized as unable to connect with citizens in ways that allow meaningful engagement with science. This critique has intensified as diverse informational environments have appeared online and contentious scientific issues (e.g GMOs, stem cells, climate change, biofuels) have moved towards the misuse of scientific evidence.

The Geography of News Project (Nouveau)

During the summer of 2015, I would like to replicate two of the intensive news-flow studies we conducted a decade ago on the Web sites of six daily newspapers, in order to assess whether any changes have occurred in the news maps these newspapers produce.

Methods and Techniques for Security Assessment of Android Apps

Besides typical personal usages, mobile devices are also being integrated into enterprises, government agencies, and military networks. Consequently, these devices held valuable sensitive information which makes them face the same level of malicious attacks that have targeted the desktop environments over the past three decades. Ensuring the securing open mobile platform such as Android requires a robust and rigorous security analysis methods and techniques.

Analysis and Design of Authenticated Encryption Schemes

Authentication and encryption are two intertwined technologies that help ensure data and network security. While in most people’s minds confidentiality is the primary goal of cryptography, message authentication is arguably as important. Deploying two separate primitives for the encryption and the authentication, in addition to being an inefficient solution, may not necessarily achieve the two required security goals. Authenticated Encryption (AE) schemes [efficiently provide both confidentiality and authentication simultaneously.

Mechanism through which an anti-aging natural compound extends longevity of yeast by remodeling cellular lipid dynamics

The fundamental mechanisms of aging are conserved from yeast to humans. We use the yeast Saccharomyces cerevisiae as a model system with which to study the molecular mechanisms of aging. Our high-throughput chemical genetic screen of extensive compound libraries has identified lithocholic acid (LCA), a bile acid, as a potent anti-aging and anti-cancer compound (Aging (2010) 2:361-370). We found that LCA extends longevity of chronologically aging yeast.

The cognitive neuroscience of indeterminate language interpretation

A hallmark of linguistic communication is that 'what is said' often underdetermines 'what is intended' by a given utterance. Sentences such as 'The author began the book' or 'The boy finished the game' are semantically indeterminate because it is not clear what the author or the boy were really doing. When the activity is not specified, interpreting these common types of sentences might rely on different linguistic and cognitive processes.

Robust Design of Preventive Healthcare Facility Networks

Preventive healthcare services aim at reducing the likelihood and severity of life-threatening illnesses through early detection and prevention. In order for such services to be effective, the preventive healthcare facilities should be easily accessible. Factors that impact the accessibility include the number, type, and location of the facilities as well as the assignment of the clients to these facilities.

Chemogenomics of antifungal drugs

Candida albicans is an important pathogen that is a significant cause of serious hospital acquired infections. Our lab has a collection of approximately 1000 C. albicans strains that have been genetically engineered to each lack a single gene. The project will be to test the effect of drugs that are used to treat fungal infections on each of the mutant strains – to determine if the mutation causes the pathogen to become more sensitive or more resistant to the drug. Mutations that cause the C.

Computational study into the stabilizing interactions in internal loops of oligonucleotides

Our focus in this computational proposal is on weak bonding interactions (WBIs) in the organization of molecular assemblies, here in particular oligonucleotides. With regards to WBIs, the hydrogen bond is certainly the most recognized, but C-H...O, C-H...pi, pi...pi and others must not be ignored if organization and stability are to be understood. WBIs are thus of fundamental importance in diverse phenomena, such as the effect of ligand-binding in ribonucleic acids on gene expression (riboswitches, mostly through pi...pi interactions).

Improve safety and productivity of construction projects using serious-game simulation

The project aims to improve construction productivity and safety by using game technology to simulate the construction processes involving earth-moving and lifting equipment (e.g. excavators and cranes). Data from the site are integrated in the simulation in real time.
