EIC project

Exciting announcement - our group at KTH/SciLifeLab will be coordinating a big cross-Europe project over the next 5 years to develop a 3D spatial molecular imaging technology from networks. The project will be conducted together with partners Erik Benson at Karolinska/SciLifeLab Stockholm, Stockholm-based sequencing technology company Single Technologies AB led by CEO Johan Strömqvist, biologists Benedetta Artegiani and Delilah Hendriks at Princess Maxima Center for Pediatric Oncology in Utrecht, Netherlands, and physicist Martin Weigt at Sorbonne University in Paris. We're funded by the EU through the EIC Pathfinder program. Read more about it here: News article link dm_scheme

Autumn update - talks, travel, and new members

This autumn, Ian, David, and Simon attended an exciting DNA30 conference in Baltimore where we learned about the latest breakthroughs in the molecular programming field. David and Simon presented the results of their recent research on finding hidden spatial information in DNA barcode networks. We were also honored to host a talk here at SciLifeLab by Joshua Weinstein, a pioneer in the field of spatial inference from molecular networks, who presented to our community the exciting work he is doing in this field. This autumn also marked the second iteration of the popular KTH master's/doctoral course Machine Learning for Biotechnology - co-taught with Anniina Vihervaara. Great to listen to the student presentations at the end! Earlier this month, Ian traveled to Japan and gave a talk on spatial molecular networks at Kyoto University's Institute for Frontier Life and Medical Sciences (LiMe) hosted by Professor Hirofumi Shintaku. And Ian is now on Bluesky - Follow and connect here! Lastly, we recently admitted Krzysztof Mrosik to our ranks who will conduct his Master's thesis with us on the informatics and computational processing of information contained in DNA barcodes. Welcome Krzysztof! dm_scheme

Summer update - preprints, new member

This spring, we welcomed new member, experienced postdoctoral researcher Joel Spratt. Joel did his PhD in Oxford, and did a postdoc at Karolinska Institutet prior to joining us, where he will be working on developing new sequencing-based technologies. This spring we also published 2 preprints. Check them out here: Dahlberg SK, Bonet DF, Franzén L, Ståhl PL, Hoffecker IT. Hidden network preserved in Slide-tags data allows reference-free spatial reconstruction. bioRxiv. 2024:2024-06. and here: Bonet DF, Blumenthal JI, Lang S, Dahlberg SK, Hoffecker IT. Spatial coherence of DNA barcode networks. bioRxiv. 2024:2024-05.

Autumn update - new members, machine learning course,

🍂 Autumn greetings! 🍂 A warm welcome to two new lab members. Dr. Anastassia Runina is joining us as a postdoc. Anastassia, with background in real-time PCR, microarrays and next gen sequencing product development, and STI detection, will be developing novel biotechnologies related to next gen sequencing with us. Johanna Blumenthal, from the Molecular Techniques in the Life Sciences Scilifelab Master program, is joining us for her Project and Master's thesis. Welcome Anastassia and Johanna! In other news, Ian is in the final weeks of a new Master's course CB206V on Machine Learning in Biotechnology, co-organized with Gene Technology Department colleague Anniina Vihervaara. Check out the recorded lectures on Youtube.

End of summer news

Big news after an exciting spring and summer. We are honored to be one of only two groups in Sweden awarded an ERC Proof of Concept grant for our project MESH_CHIP, in June we filed our first patent, and this year Dr. Erik Benson, postdoc-extraordinaire, has accepted an offer to join Karolinska Institutet as an assistant professor next spring, right here in Scilifelab. Good times!!! 🔥🔥🔥

3, 2, 1...Launch!

The Hoffecker Lab has set up shop in the amazing Gene Technology department at KTH/SciLifeLab. It is a huge honor to be among this stellar group of internationally recognized researchers.

October 7th, 2020

Founding a new lab

The Hoffecker Lab will officially launch from May 1st 2021 as a new member in the Gene Technology Department, at KTH Royal Institute of Technology on the SciLifeLab campus in Stockholm. The funding making this possible comes from an ERC Starting grant , a starting grant from the Swedish Research Council (VR), co-financing from KTH's School of Engineering Sciences in Chemistry Biotechnology and Health (CBH), central funding from KTH, and a project grant from the Åke Wiberg Foundation.

What is Molecular Programming?

Our aim is to develop novel biotechnologies that use the programmable information storage capabilities of DNA to create molecular logical circuits, control the interactions of molecules, define structures at the nanoscale, and gather information from biological specimens through DNA sequencing methods. What motivates us is the satisfaction of finding clever ways to manipulate information with molecules to do surprising and useful things!

DNA sequence-based microscopy

Our immediate focus is on exploring and growing the newly emerging field of "DNA sequencing-based microscopy", "DNA microscopy", or "imaging-by-sequencing". The goal of this field is to generate entire images without the use of traditional optics. Instead, microscopic information is recorded in molecules of DNA, stored and processed in that form, and ultimately decoded using high throughput sequencing technology and mathematics to reconstruct images. This exciting field has the potential to completely change how biological and medical information is obtained, surpassing many of the physical limitations of classical microscopy, while at the same time presenting new challenges.
