Personal Profile

I am an exceptional author who has made a significant impact in the field of vision and AI! With my extensive experience in developing cutting-edge applications in earth observation, robotics, and medical imaging, I have contributed to the literature with robust mathematical methods, algorithm design, and implementations. My expertise in explainable and interpretable AI methods has led to the development of algorithms that fulfill ethical and social needs, making AI systems understandable to a larger audience.

In 2022, I had to leave my fulltime academical position because of a disability situation. Now, I am proud to be able to create the Kallfelz Academy with my husband, within the best physical conditions that supports my wellbeing and feeling excited to offer academic and scientific partnership with individuals and institutions that value innovation and pushes the boundaries of what's possible in the world of science and technology.

Biography

Beril Kallfelz is a distinguished Dutch scientist with a profound passion for our planet. Holding a PhD in Electronics Engineering, she is dedicated to advancing computer vision algorithms that enable computers and robots to perceive and react as humans do. During her PhD, Beril focused on understanding human object recognition, developing innovative mathematical approaches for object detection, tracking, and 3D reconstruction. Her research primarily targeted Earth observation images, including satellite and airborne imagery, but she also contributed to numerous projects in robot and medical vision.

 

Beril's PhD journey involved collaborations with leading remote sensing laboratories across Europe, including the University of Trento in Italy, the Technical University of Munich in Germany, and the French research institution INRIA. In 2009, she joined the German Aerospace Centre (DLR) as a research fellow, where she continued her groundbreaking work in fully automated computer vision algorithms for object recognition, human and animal tracking, and 3D model construction.

 

While at DLR, Beril pursued habilitation research at the Institute of Geoinformatics, University of Osnabrück, focusing on advanced 3D reconstruction algorithms using diverse sensor data. She also designed and led courses in remote sensing, computer vision, and image processing at several German universities, including the Technical University of Munich, University of Augsburg, University of Osnabrück, University of Konstanz, and University of Erlangen-Nuremberg.

 

In 2012, Beril contributed to 3D object reconstruction software for two FP7 European projects at Delft University of Technology (TU Delft). She later joined the University of Twente in 2017 as a postdoctoral researcher, where she was involved in robotic vision, including drones, agricultural robots, and medical robots, as well as medical vision topics. In 2019, she accepted an assistant professor position at Jönköping University in Sweden to advance research and teaching in computer vision and explainable AI. However, due to the challenges posed by the pandemic, she returned to the Netherlands.

 

From 2021 to March 2022, Beril worked at Saxion University of Applied Sciences in Enschede as an associate professor, focusing on computer vision and explainable AI algorithms for Earth observation images. Unfortunately, health issues necessitated a series of emergency surgeries, leading her to leave her position. Currently, Beril works from her home office, continuing to learn, write, apply, and stay active in the scientific community despite her health challenges. Beril believes in lifelong learning. Although she loves teaching, she always feels like a student, eager to explore new developments in her field.

 

Besides her academic pursuits, Beril enjoys spending time with her husband and children (both human and canine). She loves painting, playing the violin and piano, growing food in her garden, and taking advantage of every opportunity to exercise outdoors.
