About
I am a postdoctoral researcher at the Center for AI in Medical Imaging, Department of Medicine, University of Bern.
During my Ph.D. studies, which commenced in March 2019, I have been involved in developing deep-learning-oriented solutions for medical applications, particularly in the analysis of surgical videos and volumetric images. My research encompassed a wide range of topics, including supervised, semi-supervised, and self-supervised deep learning methods for image quality enhancement, video action recognition, object detection, and semantic segmentation. These resulted in the development of novel neural network architectures to improve semantic segmentation performance for challenging scenarios such as deformable, scalable, occluded, blurry, transparent, and distorted objects. Moreover, leveraging sequence modeling networks (CNN-RNNs, 3D CNNs, and transformers), I have explored different directions to enhance action recognition, object localization, and instance tracking in surgical videos. I defended my Ph.D. dissertation with the highest grade at Klagenfurt University in Austria in October 2021 and continued my postdoctoral research at the same institution.
In February 2022, I joined the "AI for Medical Imaging" laboratory at the University of Bern as a postdoctoral researcher, where my work has primarily focused on "Domain Adaptation for Semantic Segmentation" for both medical and general images.
