Welcome

I'm Nishant, a soon-to-graduate PhD student in the CGV group at the Faculty of Computer Science, TU Dresden in Dresden, Germany, supervised by Prof. Dr. Stefan Gumhold. My PhD work focuses on Out-of-Distribution Detection, 2D Generative Modelling, and solving Inverse Problems using Invertible Neural Networks.

Before my PhD, I completed a Master's in Electrical Engineering at TU Dresden, Germany, graduating with the highest distinction. I earned my Bachelor's in Electronics and Communication Engineering at Dr. MGR Educational and Research Institute, Chennai, India, where I was the university topper and a gold medallist.

I have worked as a data engineer at HCL Technologies in Chennai, India, and as a software engineer at Samsung India Electronics in Noida, India. At TU Dresden, I secured research funding from the German federal government and led a research group on an industrial project focused on reliable machine learning in collaboration with Carl Zeiss Meditec AG, Germany.

Reviewing Activities: IEEE Sensors and MICCAI.

Teaching

I organized the following courses during my PhD studies at TU Dresden:
  • Complex Lab (Winter Semester 2018/19) The task was the development of an Augmented Reality application to visualize the interior of real-world objects. I supervised five Master's students for this coursework. [Link]
  • Complex Lab (Summer Semester 2020) The task was to develop a Virtual Reality application for immersive visualization of the human brain using Tractography data. I supervised around eight Master's and Bachelor's students for this coursework. [Link]
  • Advanced Seminar (Summer Semester 2023) The seminar dealt with Recent Trends in Generative AI, where students performed an extensive literature study of popular Generative AI approaches. I directly supervised six students and managed the complete coursework during the semester. [Link]
I was directly involved in supervising students for the:
  • Advanced Seminar in the Summer Semesters of 2018, 2019, 2020, 2022, and 2023.
  • Advanced Seminar in the Winter Semester of 2019
During my PhD studies, I have collaborated with three PhD students and directly supervised:
