The September talk series continues full steam ahead.

We continue the streak of exciting September talks.

Friend of the lab & postdoc at Northeastern University Piotr Sapieżyński is visiting Copenhagen and we're lucky to hear about his ongoing work on FAT (Fair, Accountable, and Transparent) Machine Learning.

Wow.

I'm very excited to have [Roberta Sinatra](http://www.robertasinatra.com) visiting the group for the week of April 3rd.

We are very lucky to have [Michael Szell](http://michael.szell.net) visiting the week of April 3rd.

We're very lucky to have [Kim Albrecht](http://kimalbrecht.com) visit for a few days later this month.

Have you recently finished your PhD?

Renowned network scientist and creator of [InfoMap](http://www.mapequation.org/code.html) (probably the world's best community detection algorithm for complex networks), [Martin Rosvall](http://www.tp.umu.se/~rosvall/), is visiting Copenhagen.

I'm super excited to announce that we recently had a new paper published in PNAS.

[Note: Thanks for the many emails on this!!

Monday June 13th is shaping up to be an exciting day for data science in Copenhagen.

A PhD defence is a great way to bring interesting people to Denmark, and Piotr's defense on June 13th is no exception.

Ulf Aslak Jensen, who's writing his M.Sc thesis in my group (well, actually he's at the Weizman institute working with Uri Alon, but that's another story) has just ***won*** *[Science Magazine](http://www.sciencemag.org)*'s [Data Stories competition](http…

Next Thursday, we're lucky to have Dave Choffnes visiting the lab.

In early December, [Alan Mislove](http://www.ccs.neu.edu/home/amislove/) (who's spending his sabbatical here in Copenhagen) and I, got the Volvo and headed out to the Amager Campus of University of Copenhagen to pick up [Anders Søgaard](http://cst.dk/ande…

As we enter the new year, it's always fun to reflect on the year that's just passed.

I recently went to the excellent [GESIS CSS Winter Symposium](http://www.gesis.org/css-wintersymposium/program/) in Cologne.

Yesterday we put together a video that briefly (40 seconds) describes our ongoing [Data Transparency Lab](http://www.datatransparencylab.org) Project *[Digital Halo](http://www.datatransparencylab.org/grantees.html).

This whole year, we're lucky enough to have collaborator & all-round awesome guy Alan Mislove spending his sabbatical connected to my group.

In early september, we have another great visitor, [Andrea Baronchelli](https://sites.google.com/site/andreabaronchelli/), who's a faculty member at *City University London*.

This week my good friend & collaborator [James Bagrow](http://bagrow.com/) ([assistant professor at University of Vermont](http://www.uvm.edu/~cems/?

When I started working on understanding social systems, privacy really wasn't on my mind.

I just love this quote which uses a Tiger Woods anecdote to illustrate what it means to be a professional.

This month we have a two excellent of long-term visitors in the group.

The header graphic (it's apparently called that even though it's displayed on the left) accompanying my updated site was created by [Andrea Cuttone](https://www.linkedin.com/in/andreacuttone), as PhD student in my group, using his cool python geo visualiz…

Emphasizing our focus on temporal networks, I am happy to announce that temporal networks czar, Petter Holme will visit the lab on Feb 18th.

*[This is part II of a series, you can find an overview [here](http://sunelehmann.com/2014/12/11/some-thoughts-on-privacy-part-0/)]* There are many reasons why privacy is important.

Later this month, we're lucky to have Jari Saramäki visiting and speaking at the lab.

*[This is part II of a series, you can find the overview [here](http://sunelehmann.com/2014/12/11/some-thoughts-on-privacy-part-0/)]* We all have a sense that privacy is important.

Recently I've been thinking a lot about privacy.

As part of our twitter bot experiment, my class on *social graphs and interactions* tried use our robots to start a #turkeyface trend on Twitter for thanksgiving.

It's not just the network structure that we care about.

This friday we're lucky to have visitor [Emilio Ferrara](http://www.emilio.ferrara.name/) presenting a talk on identifying twitter bots.

Network science buffs are in for a treat this Monday (September 1st, 2014), when we have a great set of visitors in my Group at DTU.

As part of a Master's project, Marta Magiera, a student in my group has developed a great tool for visualizing geo-data.

I often give the following writing advice to my students.

With collaborators at MIT (first author is [Yves-Alexandre de Montjoye](http://www.demontjoye.com/ "Yves")) we have just published a paper in Scientific Reports, [The Strength of the Strongest Ties in Collaborative Problem Solving](http://www.nature.com/s…

I'm giving a public lecture tomorrow, Tuesday May 20th at 8pm.

Next week, we're very lucky to have [Dirk Brockmann](http://rocs.hu-berlin.de/) visiting the lab.

With 29 pages of text and 9 pages of references, the new paper [we've just put on arXiv](http://arxiv.org/abs/1401.7233) is almost big data in its own right (ok, not quite, but it's still a nice, big chunk of work).

[PostDoc opportunity](http://www.dtu.dk/english/Research/Research-at-DTU/HC-Oersted-Postdoc---COFUND "PostDoc opportunity ") If you're a PhD student or young PostDoc interested in a "curiosity-driven, bottom-up research project" in my lab, the [Ørsted Pos…

> Some years ago (...), I said that our networked future was bracketed by the dystopian nightmares of two old-Etonian novelists, George Orwell and Aldous Huxley.

A couple of days I wrote (with Piotr Sapieżyński) about our influential Twitterbots [[click here to read more](http://sunelehmann.com/2013/12/04/youre-here-because-of-a-robot/)].

**Note**: This post is co-written with Piotr Sapieżyński *Is it possible for a small computer science course to exert measurable influence (trending topics) on Twitter, a massive social network with hundreds of millions of users?

This Thursday (Nov 21st) from 14-16, we're delighted to present two exciting talks on dynamic & complex networks.

If you're in Copenhagen, if you speak Danish, and if you're not already an expert on networks, I've got a public lecture on Complex Networks coming up at the Danish Royal Academy.

This morning, when I entered my office I was greeted by hundreds of Nexus 4 cases.

We've just posted a number of exciting new master's projects starting fall 2013 at the SensibleDTU site.

For my summer reading I'm aiming to catch up on the classics.
