Subramanian
Vanakkam! (That’s 'hello' in Tamil, my native tongue.)
I was a Research Assistant/PhD Candidate at Media Computing Group until end of 2020. As of 2022, I am working at devolo AG, Aachen, where I write software, help with UX, and analyze data.
My research is aimed at improving the workflows of data workers, who are non-professional data scientists. I use mainly qualitative methods to study how data workers prepare for and perform data science in their work. Based on my findings, I design, build, and validate software solutions to improve data workers' workflows. For an overview of my PhD, see here.
Administrative Roles
- I used to manage the kitchen at i10. This role has been taken over by Oliver, see the Kitchen Overlord page.
- I was the i10 librarian. This included maintaining the software for labeling books, maintaining publications, maintaining the CHI rankings page, and keeping the Hochschulbibliothek up to date. This role has been taken over by René, see the Librarian page.
- I used to maintain the ARPen project along with Phil. My role has been taken over by René and Oliver.The handover instructions can be found on oliver: smb://oliver.hci.rwth-aachen.de/Public/Research%20Projects/ARPen/Documentation/Handover%20from%20Krishna (internal access).
- For any questions about Designing Interactive Systems I, please contact Oliver or Marcel, who will be our TAs for the course offered in WS 2020/21.
