Broadly, my research focuses on developing numerical, computational,
and algorithmic frameworks for analyzing complex data in an effort
to better understand how the world is connected and how people make
decisions.

07.09.2020. Dane Taylor and I cochaired the SIAM Worksop on Network Science (NS20). 
06.01.2020. At long last, Random Walks on Simplicial Complexes and the normalized Hodge 1Laplacian (with Michael Schaub, Paul Horn, Gabor Lippner, and Ali Jadbabaie) has been published in SIAM Review. Here is the editor's overview. 
08.06.2019. I am very honored that Network Density of States (with Kun Dong and David Bindel) won the best paper award at KDD. 
11.09.2018. Simplicial closure and higherorder link prediction (with Rediet Abebe, Michael Schaub, Ali Jadbabaie, and Jon Kleinberg) was published in PNAS. The Cornell Chronicle article Predicting future combos, from rap songs to pharmaceuticals has the highlights. Lots of new data from this paper is available here.
