Suren Sritharan

I am a Master's student at the Technical University of Munich, where I'm studying Computer Science with a focus on Machine Learning and Computer vision. I'm also working as a working student at AstraZeneca Computation Pathology on the image analysis of tumor cells, while completing my Thesis at the Computational Pathology Lab at TUM on Diffusion models for in-silico data generation. Prior to that, I was working as a working student at TUM, first in the Providentia++ project at the chair of Robotics, Artificial Intelligence and Embedded Systems, and then at the chair of Data Analytics and Machine Learning. I completed my Bachelor's degree at the University of Peradeniya with a B.Sc specializing in Computer Engineering.

Throughout my undergraduate studies, I was fortunate to be advised by many fantastic researchers. Soon after my bachelors, I had the opportunity to work with Prof. Janaka Ekanayake and Prof. Samath Dharmaratne on the potential of AI for COVID-19 related applications. Previously, for my final year research project, I worked with Prof. Roshan Ragel, Dr. Roshan Godaliyadda, Dr. Parakrama Ekanayake, and Dr. Vijitha Herath on image quality enhancement under low/high exposure conditions. During my internship at Nokia Bell Labs, I had the privilege of working with Prof. Haris Gačanin on the application of machine learning models for dynamic wireless networks.

Research

My primary research focuses on the intersection of machine learning and computer vision, particularly their applications in various domains. I am currently investigating the use of Diffusion models for synthetic data generation to improve downstream tasks such as cell segmentation. My research encompasses a broad range of topics within machine learning and machine perception, as demonstrated by the projects and publications listed below.
