Bio. I am currently working in Dr. Kevin Smith group at Science for Life Laboratory as a postdoctoral researcher. My research is at the moment focused on two exciting areas. First and foremost, during my postdoc, I have been getting familiar to many influential medical and biomedical applications of machine learning. Thanks to the increasing availability of digitized medical data, vast interest from MDs and specialists, and maturity of many recognition algorithms, I believe it is the right time and place for the application of the machine learning tools towards a better and healthier life. Particularly, in collaboration with MD specialist researchers from Karolinska Institutet, I have been conducting research using deep learning for diagnosis and prognosis of breast cancer using the mammography and histopathological images. A second important aspect of my research lies in the general understanding and improvement of deep learning methods.

I have done my Ph.D. studies! with the honor of doing research under the supervision of Prof. Stefan Carlsson. During some periods in 2010 and 2011 I was lucky to have the opportunity of working with Dr. Ivan Laptev at INRIA-WILLOW project located in Paris!. I've also spent 3 months in Visual Geometry Group (VGG) at University of Oxford in 2013 and another 3 months at Google Research in 2016. I've got a M.Sc. degree in System, Control and Robotics from KTH School of Electrial Engineering and B.Sc. from Amirkabir University of Technology (Tehran Polytechnic) in Software Engineering!. Every now and then I've been asked to act as a reviewer! for International Journal of Computer Vision (IJCV), IEEE transactions on Pattern Recognition and Machine Intelligence (TPAMI), IEEE Robotics and Automation Letters (RA-L), Transactions on Image Processing (TIP), Transactions on Neural Networks (TNNLS), CVPR, ICCV, ECCV, ACCV, BMVC, and MICCAI.

I was born in Mashhad, Iran. My hobbies are travelling, discussion!, watching movies, reading books, and taking programming contests.


I am generally interested in machine learning and computer vision. Currently, the focus of my research is on deep learning, understanding its learning capabilities as well as interpreting its predictions. As an interesting and unique application field, I am currently working on using deep learning in the exciting field of medical image analysis.
In the past I have worked on methods for feature selection and sharing for various visual recognition tasks. In particular, the focus of my Ph.D. was on learning representation using latent SVM formulation as well as deep networks.
