Her lab has an impressive record of recruiting, training and promoting women scientists across all levels, and Prof. Zidovska is founder and faculty leader of a new group, NYU Women in Physics dedicated to providing a more welcoming and stimulating environment for women and those from other underrepresented groups in physics. Find out more on her lab website.

 

Read her article ‘Mechanical stress affects dynamics and rheology of the human genome’.

 

How do you feel about Soft Matter as a place to publish research on this topic?

I am very excited to have our paper on the genome’s dynamics and rheology published in Soft Matter. It is a great journal showcasing the interdisciplinary nature of the field of soft matter by bridging physics, chemistry and biology. My group focuses on understanding the genome as a polymer inside the cell nucleus in live cells, which is research at the interface of physics and biology. Hence Soft Matter is a great place to share our results with the scientific community.

 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

What I find most exciting about my research is also its most challenging part, that is, understanding the physics behind the dynamical self-organization of the genome and the cell nucleus in vivo. Inside living cells we can see first hand how nature relies on physical principles to carry out biological functions. In my group, we perform experiments on live human cells, obtaining measurements of physical parameters that then inform our physical picture of the genome and the cell nucleus. Such experiments are quite challenging, as their design is nontrivial given the complex nature of a living cell. Yet, that’s what I personally find very exciting, when we learn new physics directly from peering and poking into the cell.

 

In your opinion, what are the most important questions to be asked/answered in this field of research?

In my opinion, one of the big questions in my field is to understand the non-equilibrium nature of the genome and the emergent phenomena it leads to. The dynamical self-organization of the genome affects all cellular processes via the central dogma of biology, hence its understanding is critical for revealing the physics of life. I believe that these living systems can teach us new non-equilibrium physics.

 

Can you share one piece of career-related advice or wisdom with other early career scientists?

My advice would be, when identifying scientific questions to study, choose those you are sincerely passionate about and that make you happy. Your enthusiasm for the problem will then help to fuel your motivation and energy, even when you encounter obstacles.

Soft Matter Emerging Investigator – Janne-Mieke Meijer

Janne-Mieke Meijer is an Assistant Professor in the Soft Matter and Biological Physics group at the Applied Physics department of Eindhoven University of Technology (TU/e). Her research focuses on complex colloidal systems to discover the fundamental principles of how building block design influences self-organization and how to control the self-assembly process to engineer new materials. Janne-Mieke obtained a BSc. in Chemistry, a MSc. in Nanomaterial Science and a PhD in Physical and Colloid Chemistry from Utrecht University. She completed a postdoc at Lund University, and a Humboldt postdoctoral fellowship at the University of Konstanz. She received a Veni personal grant from the Dutch Research Council in 2018. She can be found on Twitter @JenneMikie and Instagram @JMs_colloids.

 

 

Read her article ‘In-situ characterization of crystallization and melting of soft, thermoresponsive microgels by Small-Angle X-ray Scattering’.

 

How do you feel about Soft Matter as a place to publish research on this topic?

Soft Matter is an excellent interdisciplinary journal bridging physics, chemistry, and biology. It is a great place to publish and follow exciting works on these soft microgels that encompass features of both colloids and polymers.

 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

I am very excited about the work we are doing on different aspects of colloidal self-organization. Thanks to advances in synthesis and versatile assembly methods we can now finely tune colloidal complexity in terms of interactions, ranging from repulsive to attractive, and from hard to soft, while at the same time we can achieve almost any particle shape. The biggest challenge right now is to bring together the expertise and control needed to perform the colloidal experiments that can become quite complex. It is our aim to have control all the way from the synthesis of the colloids to the detailed analysis of the forces at play.

 

In your opinion, what are the most important questions to be asked/answered in this field of research?

The self-assembly of molecules, nanoparticles and colloids is key to many natural and engineering processes, yet we do not fully understand how dynamic pathways or selective recognition control the final assemblies and hence the bulk material properties. To understand this complexity, we need to answer fundamental questions about how force, shape and composition dynamically interact and find out when equilibrium and non-equilibrium states emerge. Experimental studies of colloids can help us unravel these complex fundamental processes, and ultimately identify the design rules. This will open the way for a next generation of particle-based materials but will also generate new and important insights for condensed matter and biology.

 

Can you share one piece of career-related advice or wisdom with other early career scientists?

Find a research direction that you are passionate about, this will make sure you have fun in your day-to-day research, and make a career plan. Even though most of the time these plans will not pan out, I found that this is key in setting your priorities right.

Introducing the Soft Matter Emerging Investigators Series

For many years Soft Matter has showcased special collections dedicated to work carried out by researchers in the earlier stages of their research careers in our Emerging Investigator collections, most recently in our 2021 Emerging Investigators collection.

We hope that the soft matter community has found these issues to be valuable, both in the high quality of the articles and in drawing attention to newer voices in the community. The journal editors and Editorial Board consider these to have been highly successful.

In light of disruption to research programmes worldwide, we have taken the opportunity to reassess the format of this initiative, and we are now excited to announce the launch of the Soft Matter Emerging Investigators Series.

 

What is changing?

In place of a dedicated journal issue, Emerging Investigators papers will be published throughout the year. We anticipate the following benefits to this change:

  • No fixed submission deadlines allowing more flexibility for authors
  • Continual exposure of exciting work from early-career members of the community
  • Greater emphasis and focus on individual authors and research groups

We hope for this to offer a better service to our authors and readers well into the future.

 

What is not changing?

While we will no longer dedicate a specific journal issue to our Emerging Investigators, all other aspects of this initiative will remain the same. This includes:

  • Eligibility criteria (see below)
  • A dedicated web page for published articles alongside our other collections
  • Rigour and speed in peer review
  • An overall objective to showcase the full diversity of cutting-edge research carried out from soft matter scientists in the early stages of their independent careers worldwide

 

What happens now?

The Soft Matter Editorial Office will contact nominated Emerging Investigators throughout the year.

Regarding eligibility, contributors must:

  • Publish research within the journal scope
  • Currently be an independent research leader
  • Have not been featured as an Emerging Investigator in a previous Soft Matter Emerging Investigators article
  • Have either no more than 12 years of post-PhD research experience in the year of submission when taking into account any career breaks

 

Do you fit the criteria above, and wish to be featured as an Emerging Investigator in the journal? Get in touch with us at softmatter-rsc@rsc.org

Soft Matter Emerging Investigator – Shelby Hutchens

Profile picture of Shelby Hutchens

Shelby Hutchens is an Assistant Professor of Mechanical Science and Engineering. Her research interests span from ultrasoft polymeric materials characterization to plant-inspired motion. She received all her degrees in Chemical Engineering, Ph.D. and M.S. from Caltech and B.S. from Oklahoma State. She received an NSF CAREER award in 2017. She can be found on Twitter @ShelbyHutchens.

 

Read Shelby’s Emerging Investigator article “On the relationship between cutting and tearing in soft elastic solids” and check out all of the 2021 Soft Matter Emerging Investigator articles here.

 

How do you feel about Soft Matter as a place to publish research on this topic?

Many excellent articles on soft fracture find their way into Soft Matter. The community of researchers interested in this topic really seems to keep an eye on the journal, so I think it’s a great place for our findings relating cutting and tearing in elastomeric solids. It’s a particularly useful venue when results seem to bridge subfields, for instance, continuum mechanics and macromolecular science. 

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

For myself, I am excited about finally starting to understand how various material and geometric elements contribute to an overall failure response in soft solids. This isn’t to say that I think this problem is fully solved or that others did not understand much of it already. I’m still somewhat new to failure so it’s been very rewarding to get to the point that I can describe phenomena in my own words and start to probe new hypotheses. The most challenging thing about my research is that the more I do it, the less I find that I actually know. It can be exciting as well as daunting. 

In your opinion, what are the most important questions to be asked/answered in this field of research?

I don’t feel qualified to make any judgement since so many questions can seem incorrectly important or unimportant at any given time. With respect to soft solid fracture, I do think many interesting, fundamental, and likely important details remain to be understood in the failure of even simple, homogeneous solids with respect to predicting time-dependence, the effect of geometry (like needle insertion and puncture), and failure initiation, for example, from macromolecular architecture. Complications only increase when inhomogeneities and hierarchies come into play, as is the case in soft biological tissue. 

Can you share one piece of career-related advice or wisdom with other early career scientists?

Even if you start behind or are a bit slow, just keep at it. You’ve probably heard the saying that Rome wasn’t built in a day, but even a single neighborhood wasn’t built in a day. And neighborhoods have a very meaningful impact on those living in them.

Read Lauren’s Emerging Investigator article “Interfacially-adsorbed particles enhance the self-propulsion of oil droplets in aqueous surfactant” and check out all of the 2021 Soft Matter Emerging Investigator articles here.

 

How do you feel about Soft Matter as a place to publish research on this topic?

Soft Matter is a great journal to publish and follow exciting research in areas such as a colloids, polymers, emulsions, and soft interfaces.

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

Right now I am excited to understand how to control the motion and interactions between out-of-equilibrium materials such as droplets by using chemical gradients. A challenge is that many of the driving forces (like the chemical gradients, the local interfacial tensions) are very difficult to directly measure or visualize on the microscale. We often have to make inferences based on the observed behaviors and trends we find when doing systematic studies.

In your opinion, what are the most important questions to be asked/answered in this field of research?

Living systems are all out of equilibrium, making them highly adaptive. Yet, as chemists, we are very used to thinking about reactions proceeding to an equilibrium state. How do we design chemical systems that can be continuously driven and persist in different non-equilibrium states for long time periods?

Can you share one piece of career-related advice or wisdom with other early career scientists?

Don’t be afraid to dive into unfamiliar research fields; you don’t have to be an expert to discover something exciting and make an impact.

How do you feel about Soft Matter as a place to publish research on this topic?

Soft Matter provides an excellent platform where research areas at the intersection of physics, biology, and chemistry are best showcased to a broad readership.

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

The most exciting part of being a scientist and a faculty member is the role we play in the education and scientific development of graduate and undergraduate students and their engagement in research questions that are central to health, societal needs, and technological developments.

In your opinion, what are the most important questions to be asked/answered in this field of research?

The dynamics of cell membranes are central to life but there are still major gaps in our understanding of membranes “in action”, particularly on the nanoscale where vital biological functions take place. This includes protein-membrane interactions, cell signaling, and even viral budding. Developing tools, theories, and simulations that fill these knowledge gaps will be crucial to our understanding of cellular functions and how we utilize this knowledge in therapeutic discoveries and biotechnological advances.

Can you share one piece of career-related advice or wisdom with other early career scientists?

My advice for early career scientists, especially graduate students and postdocs, would be to follow their passion, to persist, and not be afraid to challenge existing dogmas. I would also encourage them to be mindful and adopt inclusive research practices that would help create a better science environment.

How do you feel about Soft Matter as a place to publish research on this topic?

I love Soft Matter, I’ve been publishing in it since my early PhD years, and am continuing to do so now when I have my own group. Soft matter research clearly interfaces with many disciplines, from materials to life sciences, but it’s really important to have a solid journal where soft matter research can be published in its own right.  Funnily enough, I wrote a paper for the “Emerging Investigators” issue when my PhD advisor was named one, so continuing this tradition feels really special to me (I also hope my students are reading this!).

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research? And, in your opinion, what are the most important questions to be asked/answered in this field of research?

I am very excited about self-assembly, which is a traditional field of soft matter, but now driven out of equilibrium, such that it can achieve functionalities similar to those observed in living systems. Along the same lines, I’m also very excited about soft matter concepts studied in vivo; in the context of living cells and tissues. I think it’s time to go live.

Can you share one piece of career-related advice or wisdom with other early career scientists? To me absolutely the most important part of a scientific career are people — your mentors, collaborators, and your mentees. They are the ones who will make this career enjoyable and new exciting things possible. My advice is to pay attention to the human side when choosing people you will work with or institutions you will join.

Soft Matter Emerging Investigator – John Kolinski

Profile picture of John Kalinski

John Kolinski studied both engineering mechanics and mathematics at the University of Illinois at Urbana–Champaign and graduated with Bachelor’s degrees in both subjects in 2008, before earning a Master’s degree in applied mathematics (Sc.M.) and a PhD in applied physics from Harvard University, in 2010 and 2013, respectively. His PhD thesis on “The role of air in droplet impact on a smooth, solid surface” was supervised by Lakshminarayanan Mahadevan and Shmuel Rubinstein. Supported by a Fulbright-Israel post-doctoral fellowship, he moved in 2014 to Israel to work with Eran Sharon and Jay Fineberg at the Racah Institute of Physics at the Hebrew University of Jerusalem. There he studied the inter-facial instabilities in fluid and solid systems such as water bells and the fracture of hydrogels. Since May 2017, Kolinski has been a Tenure Track Assistant Professor at EPFL and the head of the Laboratory of Engineering Mechanics of Soft Interfaces (EMSI) at EPFL’s School of Engineering. He can be found on Twitter @emsi_lab_epfl.

Read John’s Emerging Investigator article “Air mediates the impact of a compliant hemisphere on a rigid smooth surface” and check out all of the 2021 Soft Matter Emerging Investigator articles here.

How do you feel about Soft Matter as a place to publish research on this topic?

Soft Matter is an excellent journal. My manuscript was handled efficiently and rapidly, and the referee reports helped to improve the scope of our study.

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

I am very excited about the work we are doing in probing the stability of soft interfaces, from dynamic impact to fracture mechanics. Some of the main challenges in this work are technical and experimental in nature – we are looking to push the boundaries for how well we can measure material deformation at interfaces, particularly in 3D, for instance. For our lab, which focuses primarily on experiments, we work hard to expend the domain of what our tools can offer us in terms of useful data.

In your opinion, what are the most important questions to be asked/answered in this field of research?

Soft matter as a field is full of amazing questions, with many of the key questions related to geometry, and an incredible breadth of applicability, from biology to medicine to robotics. The central role of geometry in soft matter is a consequence of the large deformation that soft materials can undergo – often, the non-linearities that arise due to geometry are challenging to model, and require experiments to advance the science. At the end of the day, the study of these materials can lead to very useful applications. While we are not working on applications directly, we try to remain attentive to the needs of engineers working with soft matter, as well as the natural systems comprised of soft matter. Specifically, soft robotics, and medical implants / human machine interfaces stand to benefit from an improved understanding of the mechanics of soft materials. These applications are incredibly important to society, and provide great motivation for our day-to-day work on the fundamental mechanics of soft materials.

Can you share one piece of career-related advice or wisdom with other early career scientists?

I hesitate to offer unsolicited advice to strangers 🙂 I can only comment on my experience – I have never gone wrong pursuing interesting questions that I find to be challenging, and working in collaboration with people who are smarter than me to address them.
