Granell and Shai at NetSci-X

Congratulations to postdoctoral associates Clara Granell and Saray Shai for both getting selected to give contributed presentations at this week’s NetSci-X conference in Tel Aviv.

Clara discussed some of our recent work on “Epidemic spreading in localized envrionments with recurrent mobility patterns” while Saray presented on “Warping the urban space: geometry and dimensionality of urban transportation systems.”

Amusingly, they somehow managed to get assigned the same speaking time in parallel sessions. Thanks to Jesus Gomez-Gardeñes and Daniel Goldsmith for posting these pictures of Clara and Saray.

Mucha and Shai both recognized at Postdoctoral Award for Research Excellence Ceremony

It is with enormous pride that I get to further publicize that Dr. Saray Shai is one of the 10 recipients of the Postdoctoral Award for Research Excellence for the 2016-17 academic year, awarded by the UNC Office of Postdoctoral Affairs. At any given time, there are roughly a thousand postdoctoral associates associated with UNC. So this is quite an honor for her, recognizing the very interesting work that she’s been doing.

As part of today’s Postdoctoral Research Award Ceremony, Saray gave a fantastic short overview talk about some of her work on transportation networks.

Saray joins her fellow postdoc, Dr. Dane Taylor, who received this same award last year. I am exceptionally proud of both of them.

I was also excited when I heard that they and others nominated me and I was selected for the Outstanding Postdoc Mentor Award, a new award this year. Of course, it’s easy to be a good mentor to such great postdocs!

We are each very grateful to the Office of Postdoctoral Affairs for these recognitions!

Mucha, Shai & Taylor present at MBI workshop

A big thank you to all of the organizers of this week’s workshop at MBI on Generalized Network Structures & Dynamics. It was a pleasure to interact with so many colleagues and friends. And we’re grateful that we had the opportunity to present three different presentations. Mucha opened the workshop with an overview talk on “Communities in Multilayer Networks.” Dr. Saray Shai spoke on “Generalized network representations of multimodel transportation systems.” And Dr. Dane Taylor presented our work on “Contagion maps for examining spreading processes on networks.”

Photo credits go to Saray, with apologies that it means we don’t have any photos of her giving her talk!

Saray Shai’s new paper on multiplex metropolitan networks

Congratulations to current postdoctoral associate Dr. Saray Shai and her collaborators for their recent paper in Journal of the Royal Society Interface. Remarkably, they were able to show that increasing the speed of subway trains doesn’t always make for better outcomes. With a great result like that, it shouldn’t be surprising that their work has garnered some nice press coverage.

Congratulations Saray!

Postdoc activities at SIAM DS15

Congratulations to Drs. Nishant Malik, Saray Shai and Dane Taylor for their successful minisymposium organizations and presentations at this week’s SIAM Conference on Applications of Dynamical Systems (DS15).

Nishant organized a twopart minisymposium on Complex Network Theory Based Approaches in the Analyses of Complex Systems and Data, kicked off Wednesday morning by his presentation on the Role of Network Topology in Collective Opinion Formation and closed out Wednesday afternoon by Saray’s presentation on Revealing Collectivity in Evolving Networks: A Random Matrix Theory Approach.

Dane spoke Sunday morning on Topological Data Analysis for and with Contagions on Networks in a session on Dynamics on Networks and Network Topology in Ecology and Epidemiology, before hosting the minisymposium he organized on Structural and Functional Network Dynamics and Inference on Monday morning.

Group invasion of SIAM NS15

Our research group has descended upon the SIAM NS15 workshop on Network Science, co-located this year with the dynamical systems meeting at Snowbird, outside Salt Lake City. Held over two days, this year’s Network Science workshop includes 21 single-track contributed talks selected through a competitive process and 27 posters across two sessions, including 3 talks and 3 posters from our research group. (Full disclosure: Mucha was on the organizing committee for the workshop, but had no say in the selection of any of our group work.)

Postdoctoral associate Dane Taylor is speaking on “Contagions for Topological Data Analysis of Networks,” in collaboration with Florian Klimm, Heather Harrington, Miroslav Kramar, Konstantin Mischaikow, Mason Porter, and Peter Mucha.

Graduate student Sam Heroy is presenting his work on “Network Representations of Mechanical Percolation,” in collaboration with Taylor, group alumnus Feng “Bill” Shi, Greg Forest, and Mucha.

Graduate student Hsuan-Wei “Wayne” Lee is speaking on “Social Clustering in Epidemic Spread on Coevolving Networks,” in collaboration with postdoctoral associate Nishant Malik, Shi, and Mucha.

Presenting posters about their research are graduate student Alexis Sparko, postdoctoral associate Saray Shai, and Malik (describing recent work of his with undergraduate student David Spencer).

Meanwhile, postdoctoral associates Malik, Shai & Taylor will each also be busy presenting and organizing minisymposia at the dynamical systems meeting later in the week.

Congratulations to all for so strongly representing the research group!

Saray Shai presents at DNAC

IMG_2604 Postdoctoral associate Saray Shai presented in today’s seminar in the Duke Network Analysis Center (DNAC), continuing our group’s long-standing association with the DNAC. Saray’s presentation on Attacks of modular networks described her recent work towards understanding the relationship between modular structures in multilayer networks and their vulnerability to failure.

Dr. Saray Shai joins group

saray.jpgEarlier this summer, Dr. Saray Shai joined our research group. A recent graduate of the School of Computer Science at University of St. Andrews, Saray’s thesis was on “Coupled complex networks: structure, adaptation, and processes.” Before St. Andrews, Saray graduated with honors from the Israel Institute of Technology (Technion) with a B.Sc. in Mathematics and B.Sc. in Computer Science.

Saray brings her expertise to Carolina to work with Mucha’s group on projects funded by the James S. McDonnell Foundation, particularly in the area of multilayer networks. In future years, Saray may also teach a course in the Department of Mathematics.

SIAM Workshop on Network Science

The second SIAM Workshop on Network Science (NS14) this week included a strong presence from our group.

The newest member of the group, postdoctoral associate Dr. Saray Shai, kicked off the two-day meeting with a talk about her previous work on “Multiplex cities: the interplay between coupled transportation networks.”

Dr. Feng “Bill” Shi (postdoctoral associate at U. Chicago) gave a presentation on “Coevolution of network dynamics and structures,” including his published work from his Carolina graduate work and new extensions that have continued in collaboration with our group.

Postdoctoral associate Dr. Dane Taylor presented a poster on “Optimal synchronization of complex networks.”
