<p align="justify">I am an Assistant Professor founded by the Wallenberg AI, Autonomous Systems, and Software Program (WASP) at Linköping University, affiliated with the <a href="https://liu.se/en/organisation/liu/isy/icg"> Information Coding (ICG) </a> division at the Department of Electrical Engineering (ISY). My research focuses on the intersection of machine learning and digital forensics, particularly in the application of deep learning techniques for image processing. </p>
<p align="justify">With a specialization in deep learning, I am adept at addressing a wide range of detection problems, including change detection, anomaly/outlier detection, and copy-move forgery detection. My expertise spans various types of data, from optical satellite images to natural images and high-dimensional instance data.</p>
