Computing’s invisible challenge

Ning­fang Mi, an assis­tant pro­fessor of elec­trical and com­puter engi­neering, is exploring better ways of pre­dicting and man­aging demand for cloud com­puting resources.

3Qs: Who’s got your digital dossier?

North­eastern mobile sys­tems expert David Choffnes says data bro­kering, in which the data we share online is bought and sold by third par­ties, has blos­somed into a viable industry and is the reason many pop­ular apps are free. But he says the average user knows little about how their per­sonal infor­ma­tion is shared.

New tools to get your smartphone up to speed

Dave Choffnes, an assis­tant pro­fessor in the Col­lege of Com­puter and Infor­ma­tion Sci­ence, is devel­oping pro­grams that incen­tivize smart­phone users to share their data in order to improve the mobile Internet expe­ri­ence while still pro­tecting their privacy.

Face value

Assis­tant pro­fessor Ray­mond Fu is devel­oping facial recog­ni­tion soft­ware with appli­ca­tions ranging from adver­tising to crim­inal inves­ti­ga­tions. His research recently earned him a Young Inves­ti­gator award from the Inter­na­tional Neural Net­work Society.

Brilliant and motivated, but a good hire?

World-​​renowned net­work sci­en­tist Albert László Barabási was installed as the inau­gural Robert Gray Dodge Pro­fessor of Net­work Sci­ence on Monday, when he deliv­ered a lec­ture high­lighting his research on the “sci­ence of success.”

3Qs: When Web reviews aren’t what they seem

Crowd­sourced social media plat­forms such as Face­book and Yelp are increas­ingly being infil­trated by fake accounts and reviews that cloud the legit­i­macy of some online rating sys­tems. Assis­tant pro­fessor Christo Wilson dubbed this phe­nom­enon “crowd­turfing,” and he’s deter­mined to make these sys­tems more secure.

Tweeting under pressure

Cen­sor­ship on the Chi­nese ver­sion of Twitter does little to stifle dis­course, according to researchers in Northeastern’s Col­lege of Com­puter and Infor­ma­tion Science.

Researchers push the radio rainbow’s limits

In DARPA’s first ever Spec­trum Chal­lenge, com­puter sci­ence pro­fessor Gue­vara Noubir’s team dom­i­nated the com­pe­ti­tion in its attempt to transmit data from one point to another given the lim­ited fre­quency spec­trum available.

Big data’s role in business innovation

New assis­tant pro­fessor Christoph Riedl applies his research inter­ests in data sci­ence and com­pu­ta­tional social sci­ence to study sub­stan­tive research ques­tions in areas ranging from online social net­works to decision-​​making, team­work, and productivity.
