Who Am I ?

I am the Rosenbluth Associate Professor with the Department of Electrical and Systems Engineering at the University of Pennsylvania (Penn). I was born in Montevideo, Uruguay in 1975 where I lived until 2003. I received a B.Sc. degree in Electrical Engineering from the “Universidad de la Republica” in 1998 and worked for Bellsouth’s cellular operation in Uruguay for five years. I moved to Minneapolis, Minnesota on 2003 to study at the University of Minnesota (UoM). I received M. Sc. and Ph. D. degrees from the UoM on 2005 and 2007 and spent 1 year in a postdoctoral position. I started at Penn in 2008. I received the 2012 S. Reid Warren, Jr. Award presented by Penn's undergraduate student body for outstanding teaching and the NSF CAREER award in 2010. Papers that I have coauthored received the 2014 O. Hugo Schuck best paper award and student paper awards at Asilomar 2015 (as adviser), ACC 2013 (as adviser), ICASSP 2005, and ICASSP 2006. I am also a Fulbright Scholar and a Penn Fellow.

My research is in the application of signal processing to the study of networks. In particular, I have projects that involve optimal design of wireless networks, distributed signal processing and optimization, structured representations of network data, and graph signal processing. If you want a description more detailed than this one you can look at my Research page and the work I do with Ph. D. students described later in this page. More detailed information is available in my CV. A good snapshot of my work is my Google Scholar profile.

What's in here ?

This page is for my teaching and research at Penn. If you are looking for something specific, my list of journal papers is here, my list of conference papers here and my M. Sc. and Ph.D. theses here. You can also find brief high level descriptions of my research projects.

At the graduate level, I teach a class on Wireless Networking.

In the personal section there are a few materials describing Uruguay's history, culture and place in the world. I once made a steel reproduction of a constructivist painting, a story I always like telling. My children are learning to write wikis. Their first attempts are here. Links to various web resources can be found here.

Ph.D. Students

I use most of my time to work with Ph. D. students without whose help my research projects would move at a much lower pace than they do. I currently advise 10 students all of which are very smart and most of the time hardworking. This is who they are and what they do (names are listed here in order of appearance, I love them all the same):

  • Santiago Segarra. Santiago holds a degree from Instituto Tecnologico de Buenos Aires. He spent a semester at Penn as an undergraduate and started work towards his Ph. D. in Fall 2011.
  • James Stephan.
  • Aryan Mokhtari. Aryan is a graduate of Sharif University of Technology and started at Penn in Spring 2012. He received his Master's degree in Electrical Engineering from the University of Pennsylvania in 2014. His research interests include optimization, signal processing, machine learning, and big data.
  • Alec Koppel. Alec completed his Bachelor and Master's degrees, respectively, in Mathematics and Systems Science at Washington University in St. Louis in 2011 and 2012 before beginning his Ph. D. at Penn in 2012. His research focuses on online learning and stochastic optimization in centralized and decentralized settings, and its connections with online pattern recognition techniques, especially in the context of perception in robotic networks.
  • Weiyu Huang. Weiyu received the bachelor degree from the Australian National University, Canberra, Australia, and started at Penn in Fall 2013. His research interests include network theory, pattern recognition, graph signal processing, and the analysis of networked data arising from human, social, and technological areas.
  • Santiago Paternain. Santiago received his electronic engineering degree from the Universidad de la República, Uruguay in 2012. His research interest are in the area of control and optimization. He has been recently working in the design of artificial potentials to minimize a convex function on a space with convex holes.
  • Mark Eisen. Mark received his Bachelor's degree in electrical engineering from the University of Pennsylvania in 2014, after which he continued at Penn in the ESE PhD program. His research interests are primarily in the application of second order optimization methods in the distributed and stochastic settings. He has additionally done work in using network models to find a representation of writing styles for the purposes of authorship attribution.
  • Fernando Gama. Fernando received his electronic engineering degree from the University of Buenos Aires, Argentina in 2013. He was awarded a Fulbright scholarship for international students for 2014-2016. His research interests are in the area of information processing. He has been recently working on the design of sketching-and-sampling schemes that would help lowering the computational cost of applying a linear transform to high-dimensional streaming signals. Additionally, he has been doing research in the area of topological data analysis by exploring hierarchical overlapping clustering using cut metrics.
  • Shih-Ling Phuong. Ling graduated from Arizona State University in 2014 with a mechanical engineering degree before beginning the ESE Ph.D. program at Penn. Her research focuses on teams of sensors locating targets by using information theoretics as a control scheme.
  • Luiz Chamon. Luiz completed his masters in 2015 at the University of São Paulo, Brazil, from where he had already obtained his electrical engineering degree. During this time, his research involved adaptive filtering, acoustic MIMO equalization, and low complexity decimation/interpolation structures. He also worked in several projects involving acoustical design and electronics for audio signal processing and provided statistical analysis consulting in areas such as psychology and ergonomics. Luiz is currently working on topics in optimization and graph signal processing.
