Jan. 2018: Honored to receive a CHI Best Paper Award for "Examining Wikipedia With a Broader Lens: Quantifying the Value of Wikipedia’s Relationships with Other Large-Scale Online Communities". Congrats especially to awesome student authors Nick Vincent and Isaac Johnson.

Jan. 2018: Our lab has its website!:

Dec. 2017: WWW paper accepted. Congrats to student author Allen Lin!

Dec. 2017: Three ACM SIGCHI 2018 papers accepted. Congrats to student authors Nick Vincent, Isaac Johnson and Ankit Kariryaa!

Aug. 2017: Two new ACM CSCW / PACM papers: A literature review on sharing economy research (w/ Tawanna Dillahunt, Haiyi Zhu, and wonderful Ph.D. students) and an investigation of bias in five-star people-rating systems (w/ Loren Terveen, Joe Konstan, Aaron Halfaker, and [yet more] wonderful Ph.D. students).

May 2017: New paper accepted into PACM IMWUT / Ubicomp 2017 on the externalities of geographic routing algorithms, e.g. which neighborhoods win and lose with different algorithms (awesome student lead: my Ph.D. student Isaac Johnson).

Mar. 2017: Two papers accepted at ICWSM 2017: One on the substantial interdependence between Wikipedia and Google, another on the role that textual context (doesn't) play in disambiguating the meaning of emoji. Extra big high-fives to student authors Isaac Johnson, Connor McMahon, Hannah Miller, and Daniel Kluver.

Feb. 2017: Article at accepted at ACM TOCHI on research that identifies the critical role that human geography (e.g. the "Big Sort") plays in the variable effectiveness of the sharing economy (awesome student lead: Jacob Thebault-Spieker, awesome collaborator: Loren Terveen).

Dec. 2016: Four papers accepted at CHI 2017 on work with awesome students (special shout out to first authors Isaac Johnson, Allen Yilun Lin, Jacob Thebault-Spieker, Ashley Colley, and Andrew Hall) and amazing colleagues (Johannes Schöning, Loren Terveen, Shilad Sen).

Nov. 2016: New blog post on the implications of the 2016 election for human-computer interaction (my primary branch of computer science).

Sept. 2016: New paper accepted at CSCW 2017 on accurately matching "parent" Wikipedia articles with their "sub-articles" (e.g. "United States" and "American Literature"). Congrats to my Ph.D. student Yilun Lin on his first first-authored CS paper!

Aug. 2016: Started at Northwestern University!

Apr. 2016: New blog post on our paper about emoji's potential for miscommunication.

Mar. 2016: My NSF CAREER proposal on "Understanding and Addressing Geographic Inequalities in Location-Aware Technologies" was funded!

Come Work with Me!

I am currently looking for students excited about doing work at the intersection of HCI, geography, and big data. Undergraduate and graduate students who would like to join my group should feel free to e-mail me directly. Please include a little bit about yourself (e.g. your major, degrees, CV/resume) and let me know something about your research interests. I have worked with students with backgrounds in computer science, geography (with strong technical skills) and/or related disciplines.
