• I received a TITAN Xp GPU under NVIDIA's GPU Grant Program! I am so grateful!
  • I will be on the System Demonstrations Program Committee of EMNLP 2017!
  • I uploaded some notes on Deep Learning for NLP! (check out the code here)
  • GoWvis now also works for French and Spanish (with automatic language detection)!
  • I presented GoWvis at France IA!
  • My Wiley's Risk Analysis paper on how to use Kernels, Copulas and bootstrapping for safety risk modeling and simulation is now available online! (full text here)

About - CV - Contact

I am a postdoc in the Data Science and Mining team (DaSciM) of Prof. Michalis Vazirgiannis. The group is part of the Computer Science Laboratory (LIX) of École Polytechnique, in Palaiseau, France.

I received my PhD in Civil Engineering from the University of Colorado at Boulder in the Spring of 2015, under the supervision of Prof. Matthew R. Hallowell (primary advisor) and Prof. Balaji Rajagopalan. I applied NLP, predictive modeling and probability theory to raw textual injury reports in order to better understand and forecast construction injuries. My work was funded by the NSF and major American construction companies. Before that, I obtained a MS in Construction Engineering & Management (CU Boulder 2013) and a MS in Electrical & Mechanical Engineering (ESTP Paris 2011).

My research interests overspan all aspects of applied Machine Learning and statistical modeling, and how cutting-edge tools from these fields can be applied to real data to solve concrete problems. Lately, I have focused primarily on how using graph structures and graph theory can improve performance for various NLP tasks, such as unsupervised keyword(phrase) extraction, extractive/abstractive summarization, and (un)supervised text categorization.

I served as a reviewer for CIKM 2016, WSDM 2017 and AAAI 2017.
