PhD position in differential multivalent targeting of cancer-immune signaling pathways using pattern-controlled DNA-based nanoparticles. Candidate should have a good background in (cancer) immunology and be familiar with the biophysics of multivalent interactions. The project combines protein expression, DNA nanotechnology and cell biology in a multidisciplinary effort to advance cancer diagnostics and therapy.
Nanopore sensing and sequencing:
We are seeking highly motivated candidates with an interest in nanopore single-molecule sensing and sequencing to join Dr. Chan Cao’s group at the School of Life Science, EPFL (Switzerland).
The research group is focused on developing novel approaches to address questions in life science and diagnosis at the single-molecule level, especially focusing on nanopore technology. Nanopore measurement allows the characterization of molecules of interest with sub-angstrom resolution and without the need for additional labels/amplification in aqueous solution. It has been successfully applied in sequencing long fragments of DNA and has shown great potential for single-molecule proteomics applications. The main goal of the group is to push the limits of nanopore technology and maximize its potential for as many fields of application as possible. In this position, you will join a dynamic team of computational & structure biologists, biophysicists, biochemists, and analytical chemists. The applicant should have at least one of the following backgrounds: biophysics, biochemistry, analytical chemistry, molecular biology, or biomolecule synthesis. Experience in protein production and good programming skills are an advantage.
1. Biological nanopores for single-molecule sensing
Nanopore sensing is a powerful single-molecule approach currently developed for the precise detection of biomolecules, as for instance in DNA and protein sequencing. Our laboratory is developing this technology exploiting the properties of biological pores. The goal of this project is to engineer and design biological nanopores as sensing devices to be applied for proteomic analysis, disease diagnosis and data storage solutions. The project is highly interdisciplinary, includes experimental and computational aspects and interactions with a diverse network of collaborators.
2. Deep learning for molecular interfaces
Molecular interfaces are essential for the formation and regulation of all assemblies that sustain life, to define cellular boundaries and intracellular organization, and to mediate communication with the outer environment. Building on our recent development, where geometric transformers were used to predict protein interactions (see PeSTo), in this project we want to expand this approach for cryoEM data fitting and refinement, as well as drug and biomolecular design.

This interdisciplinary project is focused on using a combination of microbiology, microfluidics, microtissue models of infection, and time-lapse microscopy to study the impact of “metabolic potentiation” on the eradication of bacterial pathogens by antibiotics, with a special emphasis on hard-to-treat bacterial biofilms associated with indwelling medical devices. The student will be based in the Laboratory of Microbiology and Microtechnology at EPFL but will also work closely with our clinical collaborators in Medical Microbiology at the Lausanne University Hospital (CHUV). A background in bioengineering or microengineering is preferred but not required.
The Oates lab is exploring how spatio-temporal patterns emerge at the tissue level from noisy cellular and molecular interactions using a population of genetic oscillators in the zebrafish embryo termed the segmentation clock. This multi-cellular clock governs the rhythmic, sequential, and precise formation of embryonic body segments, termed somites, and exhibits a rich set of spatial and temporal phenomena spanning from molecular to tissue scales. Defects in this clock underlie human congenital mal-segmentation disorders (hereditary scoliosis).
Although the segmentation clock has been the dominant paradigm for 20 years, this model does not account for a fascinating classical result: the heat-shock echo, in which periodic segment defects recur, like an echo, along the axis. The interval separating the defects is 5 segments, but – critically – there are no known multiple-segment periodicities in the segmentation clock. This suggests that something fundamental is still missing from our overall picture of segmentation.
Using innovative microscopy techniques, transgenic zebrafish, biochemistry, mechanical manipulation, deep sequencing, physical modeling and good old-fashioned heat-shocks, we aim to discover the mechanism underlying the repeated defects. the aim of this PhD would be to characterize and investigate phenomena during the defects recently observed in our lab at multiple scales: single cell, synchronization between neighbor cells, large-scale wave patterns and mechanics of the tissue. We will also search in an unbiased way for genes that predict the echoes. If these sound to you like interesting questions and approaches to be explored in a challenging and interdisciplinary PhD, please talk to us.
The background we are looking for in a student include experience with zebrafish, microscopy, coding, molecular biology, bioengineering, and/or physics. Some or all of these are useful, but your key characteristics should be curiosity, independence and a love of science.
Commensals from our gut microbiota colonize epithelial surfaces that are covered with loose mucus. While animal and human experiments have taught us about the species that are able to colonize this environment, we know little about the biophysical principles guiding colonization of mucus. We are looking for a PhD student who will investigate colonization of the gut mucosa by commensals in a tissue-engineered gut organoid system.
Focus of the lab:
The human body develops from a single totipotent cell. During development, this single totipotent cell gives rise to the entire diversity of cell types of the body that ultimately make up all organs. Even though those cells are transcriptionally and functionally different, they share the same genome. Epigenetic mechanisms that regulate which set of genes will be turned on and which genes will be switched off in each cell are at work in order to maintain and generate cellular diversity.
The nervous system develops during early embryonic development and ultimately contains all different types of neurons from different regions of the body. In a series of developmental transitions, progenitors differentiate into neuron and glia lineages.
In my lab, we use neural organoids to model these developmental transitions and investigate how epigenetic processes control differentiation and cell fate. We employ single-cell genomics and imaging technologies to profile the chromatin of individual cells.
We have multiple open positions.
The successful candidates should have:
-High motivation, curiosity and a strong interest in scientific discoveries
-Drive to learn innovative technologies and perform challenging experiments
-A strong background in computational analysis of genomics data
-Good experimental skills in molecular biology (e.g. IF, IP, Western-Blot, Nuclei-Acid-Extraction, Sequencing-library preparation, Cloning)
-Ideally, experience with human iPS cell culture and curiosity to further develop in vitro culture systems
