Why Scientific Workflows?

Scientific workflows are a flexible representation to declaratively express applications with data and control dependencies, and are mainstream in domains such as astronomy, physics, climate science, earthquake science, biology, and others. Learn more.


Our Vision

The SciTech research group aims to empower the scientific community by tightening the relations between the domain scientists and current computational resources. As a result, scientists can focus on their research questions, while our open-source tools provide the computational foundations to seamlessly run their experiments and analyses in local and distributed resources.


We provide tools to automate and advance scientific analyses from the scientist's desktop to clouds and world-class supercomputers. Learn more.


We enable computational reproducible research via data provenance, and data and software preservation mechanisms. Learn more.

Big Data

Our tools automatically manage large volumes of data transfers between different computational resources and data repositories. Learn more.

Data Science

We provide tools to collect fine-grained performance data from experiments and the computational environment. Learn more.
