Tony receives the 2021 HFSP Nakasone Award

The 2021 HFSP Nakasone Award recognises Tony and Cliff for the discovery of a new state of biological matter, namely, liquid-liquid phase separation. Since 2009, the Hyman and Brangwynne labs have observed biomolecular condensation in various cell types and organisms and have helped to determine their functions in physiological and pathological conditions.

Congratulations to the Hyman and Brangwynne labs!

The Hyman lab welcomes Alexandra, Arsenii, MJ, and Peter

The Hyman lab recently recruited new members in different positions.


Maria-Jesus Olarte or “MJ” is starting as a postdoc in the Hyman lab. She completed her PhD at Harvard and Yale followed by a 1-year postdoc at Harvard, US. MJ is interested in studying the role of membranes in phase separation of protein complexes.

PhD Students

Alexandra Sergeeva is starting as a PhD student in the Hyman and Alberti Labs. The MPI-CBG has initiated rolling admissions for prospective PhD students who can apply through the IMPRS-CellDevoSys portal.

Masters Students

Arsenii Dmitriev is a Masters Student at the TU Dresden. He completed his Bachelor studies at the Kazan National Research Technological Institute, Russia. Arsenii is interested in how transcription factors form liquid-like compartments on DNA in vitro. In the Hyman lab, he plans to investigate protein properties responsible for compartmentalisation, the role of such compartments in vivo, and how their localisation as well as composition is regulated.

Peter Bos is a Masters Student at the Wageningen University, the Netherlands, specialising in Molecular life sciences. He Joined the lab through the a “student research internship” program organised by IMPRS-CellDevoSys. In the Hyman lab, he will be investigating the amyloid forming behaviour of certain proteins in vitro and in vivo. Applications to the internship program can be submitted here.

The Postdoc Summer Chalk Talks 2020 continue with Patrick McCall and Samir Vaid

Even though it’s 35°C outside and the wasp season is in full swing, a sizeable group of scientists gathered outside the entrance of the MPI-CBG to listen to Patrick McCall and Samir Vaid walk them through their research interests and outcomes in the second week of our summer chalk talk series.

Patrick McCall, an ELBE postdoc working at the Hyman and Brugués labs, started with a talk on “reverse-engineering biomolecular phases with quantitative phase microscopy”. His goal is to probe the connection between how cells design proteins from a pool of amino acids in native and modified states so that they have the desired properties that drive compartmentalisation.

Patrick McCall describes the frequency-dependent material response of the actin cortex as an example of a desirable property the cell developed through the design of the cytoskeleton

Experimentally, Patrick deploys quantitative phase microscopy using a holographic microscope at MPI-CBG to measure the refractive index of condensates formed by proteins in vitro. In aqueous solutions, the refractive index is linearly proportional to the concentration of the protein, allowing for the plotting of the binodal curve in the phase diagram. Patrick aims to manipulate the sequence of proteins known to phase separate at physiological conditions and plot their phase diagrams to deduce the effect of sequence variations on the behaviour and consequently the compartmentalisation of given proteins. By generating enough data from experiments, he then aims to infer parameters that can be used when simulating how the phase diagram of other, untested proteins would respond to changes in the sequence of said proteins, thereby predicting how mutations in genes and changes in protein sequence would affect the compartmentalisation and consequently activity of a given protein in cells.

Samir Vaid explains the role of CSF composition in determining the length of the neurogenic period in the developing mouse embryo

Samir Vaid from the Huttner lab then explained his work on examining the role of cerebrospinal fluid (CSF) composition in determining the length of the neurogenic period in the developing mouse embryo. Samir performed proteomic and computational analysis to determine the composition of the CSF at different stages of development of the mouse embryo to find the components that could determine how long the neurogenic period lasts. He aims to unveil whether manipulating the levels of these components would prolong the neurogenic period, thereby increasing the size of the upper layers of the neocortex of the mouse.

Postdoc Summer Chalk Talks 2020 take off with Tina and Thomas

Keeping in mind social distancing rules while ensuring a relaxed and informal setting, Tina, Jacobo, and Anna launched the Postdoc Summer Chalk Talks 2020 at the MPI-CBG to offer a weekly Friday seminar during the summer holidays.

In the first round, Tina Wiegend from the Hyman & Grill Labs, and Thomas Quail from the Brugués Lab, presented their research on the role of bimolecular condensates in cellular structure and function.

Tina’s talk “Actin(g) in condensates” exploring how condensates containing globular actin and its regulators WASP and Arp2/3 are regulated. She explored multiple theories to explain what she has observed in the experimental model C. elegans and in vitro reconstituted condensates from purified proteins. From mechanical forces, to compositional control and spatial conformation, Tina is testing all possibilities to explain how WASP condensates polymerise actin in the presence of Arp2/3 and control its shape, size and location. Through her research, Tina aims to answer the question “what is the role of condensates in the formation of the actin cortex in C. elegans.

Thomas followed with a rather entertaining talk, “Capillary forces and condensates” on the use of a mathematical formula to explain how FOXA1 condensates bring promoter and enhancer regions of the DNA in close proximity to induce transcription despite being linearly separated by several kilo bases (kb). FOXA1 is a pioneer factor (transcription factor that binds to heterochromatin and induce its unfolding) that has a DNA binding domain and an intrinsically disordered region that is postulated to enable phase separation. The mathematical function he developed explains the relationship between free energy and capillary forces pulling on the DNA into the condensate, allowing the promoter and enhancer regions to come in close proximity.

Opening: PhD student (m/f/d) in Biophysics

The Hyman and Zechner labs are looking for a PhD student to research the control of cellular noise via phase separation.

Brief summary:

Liquid condensates provide a potential mechanism to control molecular fluctuations in cells. We have recently provided a first proof of principle of this idea using theory and single-cell experiments. In this project, we want to explore this concept more broadly within physiological contexts and understand its functional implications for cellular control. The project has a highly interdisciplinary character and bridges between experimental work and theory. We welcome both theorists and experimentalists to apply.

Qualifications of the candidate: 

Biophysics, biochemistry, single-cell biology, theoretical physics, stochastic processes.

Relavent Publications:

  • Klosin, A.*, Oltsch, F. *, Julicher, F., Harmon, T., Honigmann, A., Hyman, A.A., Zechner, C. (2020). Phase separation provides a mechanism to reduce noise in cells. Science 367, 464-467.  *(co-first authors)

The National Academy of Sciences elected new members…

2020 NAS Awards announced

and we are happy that Tony got elected as well! Congratulations from the whole lab.

The Academy has around 2400 members amd Tony will be one of only 500 international Scientist in the Academy.

The National Academy of Sciences was founded in 1863 to “...provide independent, objective advice to the nation on matters related to science and technology“. This objective seems to be more important than ever these days.

Tony receives NOMIS award and is now NOMIS distinguished scientist

The Swiss based NOMIS foundation “…enables outstanding talent to take on high-risk research”. Now they awarded Tony and the lab $2.5 million in recognition of our “contributions to the advancement of science and human progress”. The money is awarded for the project “Phase Transitions and Biological Condensates: The Molecular Sociology of Cell Organization” and we will investigate the physical-chemical basis by which intrinsically disordered proteins phase-separate and explore the roles of phase separation in physiology and disease.

Congratulations as well to the other awardees, Ronald Evans from Salk
