We are happy to present our newest member of HASTE: Dan Rosén! Dan is joining the group of Ola Spjuth to work as a Data Engineer. In his projects he will work with data pipelines and interact closely with microscopes to help reaching the goals of HASTE to act on collected image streams and make intelligent decisions and control microscopes to prioritize collecting the most interesting data.
AI Sweden and AstraZeneca organised the Adipocyte Cell Imaging Challenge, a two-week-long hackathon to help AstraZeneca accelerate the drug development process. The task was to use machine learning in solving the problem of labelling cell images without requiring toxic preprocessing of cell cultures by predicting the content of the fluorescence images from the corresponding bright-field images.
Eight teams consisting of Swedish and international representatives from both academia and the private sector participated in the challenge. Our winning team consisted of Ankit Gupta, Håkan Wieslander, Phil Harrison, Ebba Bergman from HASTE Team and Erik Hallström from Wählby lab. The winner was selected by a jury consisting of representatives from AstraZeneca, Vinnova and AI Sweden.
The solution used the Learning Under Privileged Information (LUPI) paradigm to solve the problem. LUPI enables the inclusion of additional (privileged) information when training machine learning models, data that is not available when making predictions. In this case, the segmentation masks of the nuclei were used as the privileged information during the training of machine learning models. Our solution will help AstraZeneca to speed up the drug discovery process and bring drugs to market quicker.
More information on challenge can be found here.
We are looking for a skilled Data Engineer to join the HASTE team!
In collaboration with other researchers, develop, implement and test systems for AI-controlled automated microscopes. The task includes interacting directly with the microscope and establishing pipelines where models trained on previously taken images decide and control where the microscope should take images in the next step to reach a specific goal. We are looking for a candidate with a genuine interest in technology and automation, and who enjoys solving problems including both practical interaction with hardware (robots, microscopes) and different types of software. Since our microscopes generate large amounts of images, the position will also include large-scale data management and -analysis. You will work with researchers in AI modeling and biological laboratory sciences, and contribute to implementing methods and evaluating them for different types of biological problems.
This is a 2-year position that is part of the HASTE project, funded by the Swedish Foundation for Strategic Research (SSF) aiming at developing new, intelligent ways of processing and managing very large amounts of microscopy images in order to be able to leverage the imminent explosion of image data from modern experimental setups in the biosciences. Industry collaborators are Vironova AB and AstraZeneca AB.
A master’s degree in engineering or a university degree in a relevant field is a requirement. Good programming skills in Python and preferably more programming languages is a requirement. Experience in AI modeling, Linux systems as well as developing REST services and APIs is a requirement. Experience of AI modeling on image data, practical handling of automated microscopes and working with software containers (e.g. Docker/Singularity) is meriting.

We are currently looking for an ambitious, highly motivated Postdoc with a good background in AI and imaging to join the HASTE project.
This is a 2-year postdoc position. Assignments include development and application of methods for large-scale analysis of microscopy images using AI / Machine Learning within the framework of the HASTE project. The project focuses on AI / machine learning with quantifiable confidence or probability, based on methods such as Active Learning, Conformal Prediction, Probabilistic (Venn) Prediction, and Deep Learning. Applicants are expected to collaborate with other project members and participate in regular research visits with industry partners AstraZeneca and Vironova.
PhD degree or a foreign degree equivalent to a PhD degree in a relevant field. The PhD degree must have been obtained no more than three years prior to the application deadline. The three year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc. Documented experience with AI / ML methods and / or computerized image analysis. Experience in programming in eg Python is a requirement. Applicants should have excellent communication skills and be keen to actively interact with other team members including biologists, systems developers and researchers in AI / ML. Furthermore, applicants should be curious and creative, take initiatives and build relationships. Applicants should have good organizational ability, be able to structure work with multiple projects and solve anticipated and unexpected problems. The applicant must be able to express themselves very well in written and oral English

Unfortunately, we didn’t get a chance to enjoy the good food and beautiful environment of the Noor Castle, but we had a productive project meeting anyway. The meeting started with report reading and Salman Toor presenting his docent lecture “Distributed Computing e-Infrastructures (DCI): Challenges and Opportunities for Application Experts and Service Providers”. This was followed by intense brainstorming on the continued research in the project, and a discussion on the almost complete half-time report, and planning for the coming Tuesday seminars, which have become an important part of the project communication now that most of us work from home.
Many in the HASTE team visited the conference: Phenotypic Screening, High-Content Analysis and AI: Overcoming the Challenges that was held March 2-3rd at AstraZeneca, Gothenburg, Sweden.
Ola Spjuth shared the session AI and Machine Learning where Carolina Wählby (PI of HASTE) and Phil Harrison (PhD student in HASTE) gave presentations.
Hongru is a master’s student from the department of statistics, and his main interests in statistics include multivariate statistical methods and Bayesian statistics.
Hongru’s MSc thesis will focus on developing the better hierarchical representations of the microscopy image data from cellular experiments with the help of statistical methods, focusing on improving readability and informational efficiency of the representation.
We welcome Tianru Zhang as new PhD Student in the Hellander lab at the Department of Information Technology, Uppsala University.
Tianru obtained his Bachelor in Probability and Statistics in Mathematics at the University of Science and Technology of China in 2017. Then, he completed his Master in Statistics for Smart Data at ENSAI (The National School of Statistics and Analysis of Information of France) in 2018. Before moving to Uppsala, he was employed as Assistant Researcher at the Fujitsu R&D center Co., Ltd. where he worked on developing DeepTensor (a deep learning method using tensor decomposition) and analyzing data of personal online loans.
Andrea is doing a traineeship at the Department of Information Technology – Division of Visual Information and Interaction, Uppsala University while coursing the last semester from the master’s in Medical Physics at the University of Eastern Finland.
Andrea’s internship project focus on developing an approach of registering and aggregating short exposure miniTEM images (superresolution reconstruction). The project objective is to achieve better quality and higher resolution image compare to a long exposure one.
We welcome Ebba Bergman as new PhD Student in the Spjuth lab at Department of Pharmaceutical Biosciences, Uppsala University.
Ebba obtained her Master of Science in Engineering, with a focus on bioinformatics, from Uppsala University in 2017. Before starting her PhD Ebba worked as a full-stack systems developer for 2 years.
About the PhD project within HASTE:
Ebba is currently working on Conformal Prediction (CP) in combination with Convolutional Neural Networks. Next, she will focus on applying Learning Under Privileged Information (LUPI) on transmission electron microscopy data provided by Vironova. In general, Ebba will focus on combining machine learning methods with CP and LUPI using data provided by our HASTE-project partners.
