Mechanics of Biological Systems in Health and Disease

We invite applications for a postdoctoral research position focused on the mechanical characterization of biological systems in health and disease, combining atomic force microscopy (AFM), advanced fluorescence and confocal microscopy, and quantitative biophysics. The project aims to elucidate how mechanical properties and forces emerge from molecular and structural organization, and how these properties are altered by pathological processes across multiple biological scales.

The position is available in the team of Dr. Andra C. Dumitru in the nBIO group at LIBST, UCLouvain, within a highly interdisciplinary research environment with access to state-of-the-art instrumentation for nanomechanical probing of soft matter and correlative imaging.

Job description

You will work at the interface of experimental biophysics, mechanobiology, and quantitative biology, developing and applying innovative approaches to characterize mechanical phenotypes across scales. Research directions may include:

  • Quantitative mechanical measurements of single molecules, cells, nuclei, and tissues
  • AFM-based force spectroscopy, indentation, and correlative AFM–confocal approaches
  • Investigation of structure–mechanics relationships, including the role of post-translational modifications
  • Mechanical phenotyping in physiological and disease contexts (cardiovascular disease, diabetes, neurodegenerative diseases)
  • Integration of mechanical data with imaging-based and molecular readouts
  • Development of new experimental or analytical pipelines for multiscale mechanical analysis

The project is intentionally open and offers substantial freedom to shape research directions based on the candidate’s expertise and interests, while remaining aligned with the group’s core focus on mechanics and disease.

Profile

We are looking for a candidate who has:

  • A PhD in Physics, Chemistry, Biophysics, or a closely related field
  • Experience with atomic force microscopy or related scanning probe techniques
  • Background or strong interest in single-molecule, cell, or tissue mechanics
  • Ability to work independently as well as collaboratively within a research team
  • Strong scientific communication skills in spoken and written English

We offer

  • A fully funded postdoctoral position for 1 year, with possibility of extension
  • Access to state-of-the-art AFM and advanced imaging platforms
  • A highly interdisciplinary and collaborative research environment within LIBST, UCLouvain
  • Opportunities for scientific independence, method development, and career development
  • Integration into an active international network in biophysics and mechanobiology

Application

Interested candidates should submit the following to Dr. Andra C. Dumitru by email.

Ten years ago, I returned from ETH Zurich to launch my own research group thank to the FNRS… a small team with big ambitions to explore the fascinating world of molecular interactions at the single-molecule level.

A decade later, it’s incredible to look back at how far we’ve come. Over these years, I’ve had the privilege of working alongside many brilliant scientists… talented, curious, and creative minds who have shaped the identity and success of the lab. Today, many of them are shining in research institutes and companies all around the world, continuing to push the boundaries of science.

This milestone is not just about time, it’s about the journey, the discoveries, the challenges overcome, and the people who made it all possible.

Here’s to the past 10 years of curiosity, collaboration, and discovery… and to the exciting adventures still ahead!

Staphylococcus aureus colonizes the human skin, thereby causing various disorders, including eczema. Highly virulent strains that are resistant to multiple antibiotics represent a leading cause of nosocomial infections that are difficult to eradicate, emphasizing the need for alternative treatments. Attachment of S. aureus to the skin involves specific bacterial cell surface proteins that bind to target ligands on the outer surface of the epidermis. 

In a recent study published in Science Advances, research teams from Auburn University, University of Birmingham, and UCLouvain used in vitro and in silico single-molecule force spectroscopy to demonstrate that the staphylococcal serine-aspartate repeat D (SdrD) protein forms ultrastrong bonds with the skin protein desmoglein-1 (DSG-1). This is among the strongest non-covalent protein-protein interaction ever reported, explaining why the pathogen remains attached to the skin even after scratching or washing, and helping us understand why these infections are so difficult to get rid of. Remarkably, the teams discovered that calcium, an element better known for strengthening bones, plays a key role in fortifying this bacterial grip. When calcium levels are reduced, the bond between SdrD and DSG-1 weakens significantly. When calcium is added back, the bond becomes even stronger. 

This finding is particularly relevant for patients with eczema, where disrupted calcium gradients amplify SdrD interactions, which could potentially intensify S. aureus virulence. This study provides crucial insights into the calcium-dependent regulation of pathogen adhesion and opens the door to new strategies for combating antibiotic-resistant infections. Instead of trying to kill bacteria directly, which often drives the evolution of resistance, scientists could design therapies that block or weaken bacterial adhesion.

Postdoc in Tumor-Immune Crosstalk and Signaling Dynamics

The NanoBiophysics Lab at UCLouvain is seeking a dynamic and motivated postdoctoral researcher to join a multidisciplinary team investigating tumor-immune system interactions through a biophysical lens. This project aims to understand how properties of the tumor microenvironment influence immune cell behavior, with a focus on immune receptor and downstream signalling protein recruitment in different biophysical contexts. The ultimate goal is to identify new therapeutic strategies to counteract tumor-induced immunosuppression.

The successful candidate will combine molecular biology, immunological assays, and cutting-edge biophysical techniques to explore how immune cells sense and respond to tumor-associated signals. The research will involve fluorescence-activated cell sorting (FACS),  confocal imaging and various biophysical techniques, to characterize immune phenotypes and their mechanical, structural, and molecular interactions within the tumor microenvironment.

Qualifications:

•    A PhD in molecular biology, immunology, cancer biology or a related field.
•    Hands-on experience with FACS and standard molecular biology techniques (e.g., PCR, ELISA, RNA sequencing).
•    A strong background in immunological assays and immune cell phenotyping.
•    Interest in biophysical methods 
•    Excellent organizational, analytical, and communication skills.

Please send your application including a cover letter explaining your background, a CV and names and contact details of 2-3 references by E-mail

A big thank you for this visit and for sharing your knowledge with us! Looking forward to future discussions and collaborations.

We were delighted to welcome Robb de Vries from Utrecht University (Netherlands) for a visit and seminar at our institute. His expertise in virus-glycan interactions provided fascinating insights into how viruses engage with different glycan structures.

We had the pleasure of starting the year with a visit from Prof. Rafael Bernardi from Auburn University! After collaborating remotely for quite some time, it was a true privilege to finally interact in person. Prof. Bernardi delivered a memorable presentation that captivated everyone in the lab. The rest of the day was filled with enriching discussions, providing invaluable insights and inspiration for our researchers. We are deeply grateful for his visit and look forward to continuing this fruitful collaboration!

On January 6, 2025, the nBIO lab celebrated the traditional Galette des Rois with a twist of friendly competition. After much suspense and some very strategic bites, we crowned our new lab royalty: a King, a Queen, and—because one crown wasn’t enough—a Princess! Long live the Royal Family of nBIO! May their reign be filled with groundbreaking discoveries, occasional coffee breaks, and an endless supply of galettes. 🎉

We are thrilled to announce that our latest research, titled “Probing SARS-CoV-2 membrane binding peptide via single-molecule AFM-based force spectroscopy”, has just been published in Nature Communications! You can find the full article attached here.

Congratulations to all the authors! We extend our heartfelt thanks to Prof. Rafael Bernardi (Auburn University) for his valuable collaboration and insightful contributions. This work would not have been possible without the generous support from FNRS, WELBIO, and the Excellence of Science (EoS) program.

Let’s continue pushing the boundaries of science together! 🚀
