Krishna Subramanian

I worked as a Research Assistant at Media Computing Group, RWTH Aachen until 2020. Since May 2021, I am working at devolo AG, where I use my interdisciplinary skills in software development, UX, and data science to improve devolo products.

#About me

Before joining Media Computing Group, I obtained my Master's degree in Media Informatics from RWTH Aachen. Previously, I obtained my Bachelor's degree in Computer Science from Amrita University, India. 

At Media Computing Group, my responsibilities included contributing to development and UX projects; mentoring junior researchers and developers; teaching courses, labs, and seminars about UX; and fulfilling administrative roles. See my work webpage for details about the courses and labs I helped teach/organize, student theses I supervised, and administrative duties I took on during my time as a Research Assistant.

#Skills

Design thinking

My dissertation is centered around HCI. I use design principles and novel interaction techniques to support data workers' workflows. I acted as a TA for our introductory HCI course and mentored various UX projects.

Quantitative research

This is the main focus of my dissertation. To understand how data workers learn and perform data science, I needed to have a good understanding of hypothesis-driven data science methods. I also hold data science lectures, and promote ethical, transparent practices in my lab.

Qualitative research

As a part of my research, I have conducted numerous studies and analyzed the resulting data using qualitative methods. I am familiar with contextual inquiries, affinity diagrams, qualitative coding, and interaction analysis.

Programming

I have worked on several web-based, desktop, and mobile projects. I am proficient in Angular, D3, R, Swift, Python, and C++.
