Postdoc and PhD positions in MACHINE LEARNING with applications
to PROACTIVE INFORMATION RETRIEVAL AND BIOINFORMATICS

Helsinki University of Technology

We are looking for two postdocs and one PhD student to join a research
group working on machine learning and probabilistic modeling, with
applications in bioinformatics, neuroinformatics and information
retrieval. The Machine Learning and Bioinformatics Group
(http://www.cis.hut.fi/projects/mi) belongs to the Adaptive
Informatics Research Centre at the Department of Information and
Computer Science, and to the Helsinki Institute for Information
Technology HIIT, Helsinki University of Technology, Finland.

--------------------------------------------------------------------

Postdoc #1 and PhD student: Proactive information retrieval

Proactive or cognitive user interfaces require modeling user behavior
and state, in order to provide optimal selection of natural choices
for the user in varying contexts. They provide an exciting opportunity
for developing advanced probabilistic machine learning methods for
inferring the user's interest from noisy signals like measurements of
attention.  You will take part in international projects developing
e.g. gaze-based information retrieval tools and personalized
information navigators.

Keywords: Proactive interfaces, information retrieval, user modeling,
probabilistic modeling, graphical models

Postdoc:
1.5 years + option for extension, starting date 1.9.2009 or flexibly
thereafter. Salary range 2523.02 - 4385.49 Euro per month.
PhD student:
4 years, starting date 1.9.2009 or flexibly thereafter.
Salary range 1716.96 - 3208.97 Euro per month.

Postdoc #2: Bioinformatics

The aim is to develop models that learn to combine multiple data sources in
multiple experimental settings, for systems-level modeling of a new
experiment. From machine-learning perspective this is a challenging
combination of multi-view and multi-task learning, where the number of
samples compared to the dimensionality is very low and fundamental
research is needed. From systems biology perspective this is an
opportunity to solve some of the central problems in cellular
regulation. The project is carried out in collaboration with experts on
the data and the biological applications (cancer and plant signaling).
You will need particularly skills on machine learning and
probabilistic modeling, as well as good collaboration skills.

Keywords: graphical models, MCMC, relational models, interactomics,
multi-view learning, multi-task learning

1 year + option for extension, starting date 1.9.2009 or flexibly
thereafter. Salary range 2523.02 - 4385.49 Euro per month.

--------------------------------------------------------------------

All positions require a relevant degree, and good skills in a subset
of the following fields: computer science, programming, machine
learning, statistics, mathematics, and bioinformatics.

In Helsinki you will join the innovative international computational
data analysis and ICT community. Among European cities, Helsinki is
special in being clean, safe, liberal, Scandinavian, and close to
nature; in short, having a high standard of living. English is
understood everywhere and the working language is English.

The is no formal deadline, but the applications will be processed
starting from the beginning of August. I will not be easily reachable
during July. Please attach a CV including a list of publications, copy
of study records, and email addressses of 2-3 people willing to give
more information. Include a brief description of research interests
and send the application by email to
