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.

Magic and symmetry in mathematics

North­eastern Uni­ver­sity asso­ciate pro­fessor of math­e­matics Ivan Loseu was named a Sloan 2014 Research Fellow for his con­tri­bu­tions to the field of rep­re­sen­ta­tion theory, a sophis­ti­cated branch of algebra.

The dark side of fair play

Spite is a puz­zling human behavior that seem­ingly affords no value to its owner. But new research from assis­tant pro­fessor of phi­los­ophy Rory Smead reveals that spite­ful­ness may actu­ally be the unlikely origin of the kindly act of fairness.

Your face says it all? Not so fast

New research from Uni­ver­sity Dis­tin­guished Pro­fessor of Psy­chology Lisa Feldman Barrett’s lab refutes a decades-​​old belief in emo­tion science—that emo­tions are uni­ver­sally rec­og­nized across people and cultures.

3Qs: Drug diagnosis

Chem­istry and chem­ical biology pro­fessor John R. Engen uses a novel tech­nique to ana­lyze large, com­plex bio­phar­ma­ceu­tical drugs—which could have major impli­ca­tions for health­care and its asso­ci­ated costs.

The ‘Model’ of excellence

A team of North­eastern stu­dents placed first at the 29th Annual Inter­na­tional Model NATO con­fer­ence in Wash­ington, D.C., a feat that is even more impres­sive when con­sid­ering the cir­cum­stances under which the group won.

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.”

A VAST solution for airport security

Advanced video ana­lytics tech­nology devel­oped by researchers in Northeastern’s ALERT Center helps TSA agents make better use of data col­lected by sur­veil­lance cam­eras at Cleve­land Hop­kins Inter­na­tional Airport.
