Holger Roth


Since June 2018, I am a Senior Applied Research Scientist at NVIDIA's deep learning for medical imaging research group based in Bethesda, Maryland. Previously, I was Assistant Professor (Research) at Mori Laboratory, Nagoya University, Japan, and Visiting Research Fellow at the National Institutes of Health Clinical Center, USA, after graduating with a PhD from University College London, UK. My current research focuses on the application of deep learning methods for large-scale medical image analysis, multi-scale computational anatomy, and computer-aided detection and diagnosis.

I am also Associate Editor for IEEE Transactions on Medical Imaging.

In 2018, I won the Young Scientist Publication Impact Award for my work entitled ""A New 2.5D Representation for Lymph Node Detection Using Random Sets of Deep Convolutional Neural Network Observations", originally presented at MICCAI 2014.


I started my undergraduate degree in 2003 in Electrical Engineering at the University of Applied Sciences Würzburg-Schweinfurt, Germany.

My first research during my studies was conducted in 2007 during an internship at the Fraunhofer Institute in Fürth (Germany), specialising in Computed Tomography (CT) for non-destructive testing.

I subsequently gained an MSc in Vision, Image and Signal Processing at Heriot-Watt University in Edinburgh in 2008, working on computer vision algorithms for autonomous underwater vehicles.

In 2009, I started a PhD at the Centre for Medical Image Computing at University College London, UK, under the supervision of Prof. David Hawkes and Dr. Jamie McClelland. I specialised in the registration of highly deformable organs such as the colon and navigation for colonoscopy.

From 2013 to 2016, I was a Visiting Research Fellow the Imaging Biomarkers and CAD Lab at the National Institutes of Health Clinical Centers, Bethesda, USA, with Dr. Ronald Summers and Dr. Le Lu.

From August 2016 to May 2018, I was conducting my research as an Assistant Professor (Research) at Mori Laboratory, Nagoya University, Nagoya, Japan. My project was funded as part of the MEXT grant "Multidisciplinary Computational Anatomy and Its Application to Highly Intelligent Diagnosis and Therapy".
