 ## About the developer<a name="about-the-developer">
 modAL is developed by me, [Tivadar Danka](https://www.tivadardanka.com) (aka [cosmic-cortex](https://github.com/cosmic-cortex) in GitHub). I have a PhD in pure mathematics, but I fell in love with biology and machine learning right after I finished my PhD. I have changed fields and now I work in the [Bioimage Analysis and Machine Learning Group of Peter Horvath](http://group.szbk.u-szeged.hu/sysbiol/horvath-peter-lab-index.html), where I am working to develop active learning strategies for intelligent sample analysis in biology. During my work I realized that in Python, creating and prototyping active learning workflows can be made really easy and fast with scikit-learn, so I ended up developing a general framework for this. The result is modAL :) If you have any questions, requests or suggestions, you can contact me at <a href="mailto:85a5187a@opayq.com">85a5187a@opayq.com</a>! I hope you'll find modAL useful!
