Work experience

summer 2006:
- Yahoo Research, Santa Clara, CA, USA.
  With Ravi Kumar, Andrew Tomkins and Lars Backstrom on microscopic (edge-by-edge) evolition of social networks.
  With Michael Mahoney, Kevin Lang and Anirban Dasgupta on existence of communities and communities in large networks.
summer 2006:
- Microsoft Research, Adaptive Systems and Interaction, Redmond, WA, USA.
  With Susan Dumais and Eric Horvitz we were working on web projections (learning from contextual subgraphs of the web), and the dynamics of a instant messenger network of 240 million people (which is the largest social network analyzed up to date).
summer 2005:
- HP Labs, Information Dynamics Lab, Palo Alto, CA, USA.
  With Lada Adamic and Bernardo Huberman we were playing with a large person-to-person product recommendation network. We were measuring the influence of product recommendations on people purchasing products. The basic question is: Does the word-of-mouth really work?
summer 2003:
- Carnegie Mellon University, Computer Science Department, Center for Automated Learning and Discovery, Pittsburgh, PA, USA.
  With Christos Faloutsos and Deepayan Chakrabarti we were playing with large graphs. We were exploring power-law graph generation and sampling.

  Projects on machine learning, data mining, text mining, link analysis and Slovenian text to speech technologies.
summer 2002:
- Royal Holloway University of London, Department of computer science, Egham, UK.
  I was working with John Shawe-Taylor on text classification on uneven training sets. We improved boosting using Linear Programming to gain robustness on uneven traing sets.
summer 2001:
- Microsoft Research, Integrated Systems Group, Cambridge UK.
  I was working with Natasa Milic-Frayling on enhancing web browsing history navigation and search over already seen web pages and better in-session navigation. As a result of this work we filed 2 patent applications.
summer 2000:
- European Commission Joint Research Centre , European Union's scientific and technical research laboratory. ISIS Institute (Ispra, Italy). I was working on IDEA project.
1998, 1999:
- Computer Vision Laboratory at Faculty of Computer and Information Science, University of Ljubljana.
  Projects on stereoscopic computer vision and object recognition and industrial image registration.
summers 1998 and 1999:
- Lionhearth Technologies, Los Gatos, CA, USA. We were working on 3D characters (avatars) over the internet and real-time stereoscopic image recognition.
1996, 1997:
- Hermes Softlab (largest Slovenian software house). Involved in several projects from the area of system programming.
