2021 JPC Lectureship Winners Announced

The recipients of 2021 The Journal of Physical Chemistry (JPC) and PHYS Division Lectureship Awards are:

  • Christopher J. Johnson, Assistant Professor, Department of Chemistry, Stony Brook University
  • Diwakar Shukla, Blue Waters Assistant Professor, Department of Chemical and Biomolecular Engineering, University of Illinois at Urbana-Champaign
  • Emilie Ringe, University Lecturer, Department of Earth Sciences & Department of Materials Science and Metallurgy, University of Cambridge

The Journal of Physical Chemistry– PHYS Division Lectureship Awards honor the contributions of investigators who have made major impacts on the field of physical chemistry in the research areas associated with each section of the journal – JPC A, JPC B, and JPC C.

I spoke with the recipients to find out what the award means to them.

Christopher J. Johnson – JPC A Recipient

Christopher J. Johnson received his B.S. in Physics from Butler University in 2005, and his Ph.D. in Physics from University of California, San Diego in 2011 under the guidance of Robert Continetti in the Chemistry department.  He was awarded an NSF American Competitiveness in Chemistry Fellowship to work with Mark Johnson at Yale University, and began his independent career at Stony Brook University in 2014.  Johnson group members focus on molecular-scale aspects of particle properties and reactivity with emphasis on atmospheric particles and metal nanoclusters. Johnson has received an Air Force Office of Scientific Research Young Investigator award and the Flygare Award at the International Symposium on Molecular Spectroscopy.

What does this award mean to you?

I am lucky to have great mentors and to mentor great undergraduates, grad students, and postdocs. An award like this recognizes all of their efforts, particularly those brave enough to volunteer to work for an unproven new professor with an empty lab!

What are you working on now?

A major thrust of our work is trying to merge molecular-scale and particle-scale descriptions of the chemistry happening at the surface of particles, whether these are metal nanocluster catalysts or few-nanometer-sized atmospheric clusters.  In both cases, the complexity of the particle side of the problem makes it difficult to disentangle the molecular mechanisms driving reactivity or growth.  We adapt precise chemical physics techniques to isolate these particle-molecule complexes and perform relatively high precision spectroscopy and reactivity measurements, and then we have to figure out how to deal with the complexity of the results and actually figure out what they mean.

What advances are you hoping to see in your field in the next decade?

Gas phase chemical physics techniques offer the opportunity to gain detailed insights into complex chemical systems beyond what you routinely see using more traditional experimental methods, but they are limited in the chemical complexity they can address. I am hoping to see, and contribute to, continuing efforts to expand the suite of methods we have to faithfully capture complex chemical systems and deliberately manipulate them into their relevant states and configurations to solve problems across a range of chemical disciplines.

Why do you choose to publish your research with The Journal of Physical Chemistry?

I have fond memories of my first paper ever and my first paper in my independent career being published in JPC LettersJPC has great editors who get what we are trying to do, so I trust them to handle our papers and help us to improve and disseminate them.

Diwakar Shukla – JPC B Recipient

Diwakar Shukla is a Blue Waters assistant professor in the Department of Chemical and Biomolecular Engineering at University of Illinois at Urbana-Champaign. His research work is focused on understanding the biological processes using physics-based models and techniques. He started his research career at the Indian Institute of Technology (IIT) Bombay, India, where he received B. Tech and M. Tech. degrees in chemical engineering. He then joined Massachusetts Institute of Technology where he received M.S. and Ph.D. degrees in chemical engineering. In his independent career, he has received several awards for his research and teaching, including the NSF Early CAREER award, the  ACS COMP OpenEye Outstanding Junior Faculty Award, and the Sloan Research Fellowship in Chemistry.

What does this award mean to you?

It is a special honor for me because The Journal of Physical Chemistry has been my preferred place for publishing fundamental, mechanistic, and methodological papers. The award not only recognizes my efforts but also contributions from numerous co-authors over the years especially students, mentors, and collaborators.

What are you working on now?

One of the key areas of research in my group is at the interface of physical chemistry and plant biology. In particular, my research group has focused on the development and application of physics-based simulation approaches for problems at the interface of biophysical chemistry and plant sciences that would provide detailed structural and dynamical information about the molecular machinery in plants. Despite the broad utility of biophysical modeling and increased use of computational tools within the field of plant biology, there has thus far been limited application of molecular modeling beyond photosynthesis research. Out of ∼52 million protein sequences that are available on the UniProt database, only ~200,000 (< 0.5%) have structures deposited in Protein Data Bank, and only ∼4,000 (2%) of these structures are of plant proteins. Therefore, my research group is developing methods to overcome this challenge and understand sequence-structure-function relationship for plant proteins.

What advances are you hoping to see in your field in the next decade?

The key advance would be availability of tools that could help in rapid structural characterization of protein conformational ensemble. These tools could employ a combination of experimental spectroscopic techniques, artificial intelligence, molecular simulations to infer structure-function relationship for proteins.

Why do you choose to publish your research with The Journal of Physical Chemistry?

I would quote Professor Joan-Emma Shea (J. Phys. Chem. B 2020, 124, 2, 313), “The answer is simple. JPC is our home, our community, where we can come together and exchange ideas.” The journal and my research are focused on publishing new fundamental science, physical insights, methodologies, and their application to interesting scientific problems. The core focus of the journal and my research group is same, and that is why we have published many papers in the journal.

Emilie Ringe – JPC C Recipient

Emilie Ringe is a University Lecturer, (a position similar to an assistant or associate professor role) in multi-scale, multi-dimensional imaging of natural and synthetic materials at the University of Cambridge, joint between the Department of Materials Science and Metallurgy and the Department of Earth Sciences. She earned her B.A. and M.S. summa cum laude in chemistry (2008), then a Ph.D. in chemistry and materials science (2012) under the supervision of Professors Laurence Marks and Richard Van Duyne at Northwestern University. She then became the Gott Research Fellow at Trinity Hall as well as a Newton International Research Fellow (Royal Society) in the Electron Microscopy group in the Materials Science and Metallurgy Department at the University of Cambridge, supervised by Professor Paul Midgley. In 2014, she joined Rice University as an assistant professor, where she established the Electron Microscopy Center and received funding from the Air Force Office of Scientific Research (YIP), NSF, ACR-PRF, 3M, and the U.S./Israel Binational Science Foundation. She moved to Cambridge in 2018 where she received an ERC Starting grant to pursue her studies of Earth-abundant plasmonics.

What does this award mean to you?

It is a great honor to be recognized by this community of fellow physical chemists for the work my group has achieved through the years. The Journal of Physical Chemistry C has been instrumental to my career at all stages, from my first first-author paper in 2010 to my first last-author paper at Rice University in 2016 and the first paper of my new group in Cambridge in 2019.

What are you working on now?

My group works on many projects, but I would say one of the unifying themes is our interest in abundant metals such as magnesium for plasmonics. We started exploring colloidal syntheses of magnesium nanoparticles for plasmonics over three years ago, and along the way many exciting discoveries, stimulating opportunities and puzzling challenges have emerged. We are now rapidly expanding both fundamentals and applications of nanosystems based on these structures.

What advances are you hoping to see in your field in the next decade?

Many surprising ones, I hope! In plasmonics in general, I believe it is time to consider sunlight-driven processes. The last decades have seen plasmonics develop as a powerful tool to manipulate light at the nanoscale, why not couple this with the infinite light supply provided by the sun?

Why do you choose to publish your research with The Journal of Physical Chemistry?

The Journal of Physical Chemistry supports the community of physical chemists around the world and provides a visible platform for my group’s work. I know that our papers published in The Journal of Physical Chemistry are viewed and read, as were those of the trailblazers before me.
