Karen Goldberg, Professor and Nicole A. Boand Endowed Chair in Chemistry, joins 228 new members of the American Academy of Arts and Sciences this year. “It is an honor to welcome this new class of exceptional women and men as part of our distinguished membership,” said Don Randel, chair of the Academy’s Board of Directors. “Their talents and expertise will enrich the life of the Academy and strengthen our capacity to spread knowledge and understanding in service to the nation.”
Goldberg’s research focuses on designing more efficient catalysts. Better catalysts can transform industrial production methods for everything from pharmaceuticals to construction materials. Goldberg’s approach is to gather detailed data on the mechanisms by which certain chemical reactions occur and synthesize the desired products. This information is crucial to help develop catalysts that are more precise in the types of chemical products they yield, and more efficient and sustainable in terms of the amount of materials and energy used.
Goldberg also serves as director of the National Science Foundation-funded Center for Enabling New Technologies through Catalysis, a consortium of 20 faculty members and research labs at more than a dozen universities and research institutions that are pursuing innovative approaches to catalysis. Goldberg is a member of the Washington State Academy of Sciences, a Fellow of the American Association for the Advancement of Science, and in 2016 received the American Chemical Society Award in Organometallic Chemistry.
Founded in 1780, the American Academy of Arts and Sciences is one of the country’s oldest learned societies and independent policy research centers, convening leaders from the academic, business and government sectors to respond to the challenges facing the nation and the world. Current research focuses on higher education, the humanities, and the arts; science and technology policy; global security and energy; and American institutions and the public good.
Members of the 2017 class include winners of the Pulitzer Prize and the Wolf Prize; MacArthur fellows; Fields medalists; Presidential Medal of Freedom and National Medal of Arts recipients; and Academy Award, Grammy Award, Emmy Award, and Tony Award winners. A full list can be found here.

We are delighted to announce that Dr. Alexandra Velian will join us as Assistant Professor of Chemistry.
Dr. Velian completed her undergraduate studies in chemistry at Caltech, where she conducted research with Professor Jonas C. Peters prior to developing the synthesis of low-valent mono- and bimetallic complexes supported by a rigid terphenyl diphosphine framework with Professor Theodor Agapie. She received her Ph.D. under the direction of Professor Christopher C. Cummins at MIT, where she developed the synthesis of anthracene and niobium-supported precursors to reactive phosphorus fragments and studied their behavior using chemical, spectroscopic, and computational methods. Notably, this work gave rise to the synthesis of the 6π all-inorganic aromatic anion heterocycle P2N3−, produced in the “click” reaction of P2 with the azide ion. She is currently a Materials Research Science & Engineering Center postdoctoral fellow with Professor Colin Nuckolls at Columbia University, where she is working to create well-defined functional nanostructures by linking atomically precise metal chalcogenide clusters.
Dr. Velian will launch her research program at the University of Washington in July 2017. Her independent program will focus on the development of synthetic strategies to access new generations of molecular and heterogeneous inorganic catalysts and electronic materials. In the long term, she seeks to contribute fundamental understanding of chemical processes happening at the surface of semiconductor materials. With a primary foothold in inorganic and organometallic chemistry, her research program will interface with chemical engineering and materials science.
For more information about Dr. Velian and her research, please visit her faculty page or contact her directly via firstname.lastname@example.org.
The Department of Chemistry congratulates Assistant Professor Champak Chatterjee on his promotion to associate professor with tenure, effective September 16, 2017.
Research in the Chatterjee group focuses on various aspects of protein regulation by reversible chemical modifications. By investigating how the biophysical and biochemical properties of key bacterial and human proteins change with their modification states, the Chatterjee group is uncovering the molecular mechanisms that drive critical events in cell growth and survival, such as gene transcription and protein degradation. This mechanistic knowledge enables the design of therapeutics that selectively target protein-mediated processes that are misregulated in a wide range of human diseases.

Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades.
But in a paper published in the Dec. 2 issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.
“This fundamental process in chemistry and biology has eluded a firm explanation,” said co-author Anne McCoy, professor of chemistry. “And now we have the missing piece that gives us the bigger picture: how protons essentially ‘move’ through water.”
The team was led by Mark Johnson, senior author and a professor at Yale University. For over a decade, Johnson, McCoy and two co-authors — Professors Kenneth Jordan at the University of Pittsburgh and Knut Asmis at Leipzig University — have collaborated to understand how molecules in complex arrangements pass along charged particles.

Recent work by Associate Professor David Masiello and colleagues was highlighted in a November 7 article in Nature Photonics. The research was also highlighted in Chemical & Engineering News and in a News & Views feature article in Nature Photonics.
Measurement of the two distinct components—scattering and absorption—of a single nanoscale object’s optical extinction provides fundamentally important and complementary information on how that object processes light: either scattering it back to the far-field or converting it into internal excitation. Today, various techniques exist to measure the scattering from individual nanoscale objects, all relying on the detection of scattered photons in regions of zero background. Measuring their absorption, however, is much more complicated due to the fundamental inability to detect extremely small reductions in transmission over statistical fluctuations in the number of photons. This means that the spectroscopic signature of the vast majority of molecules—specifically, those that are transformed into dark states through photoreactions—is difficult to access.
To overcome this challenge, researchers in the Masiello group and the Goldsmith group at the University of Wisconsin–Madison devised a new experimental route to measure the absorption spectra of individual, nonemissive nanoscale objects by photothermal contrast in an optical microresonator cavity.
Photothermal spectroscopies function by inferring an object’s absorption from the localized temperature increase and resulting refractive index inhomogeneity produced by the excited object’s nonradiative decay. In their work, the team coupled individual plasmonic nanorods to an ultrahigh-quality optical microresonator cavity and succeeded in determining the nanorod’s absorption spectrum by monitoring the temperature-dependent attometer shifts in the resonance frequency of microresonator’s whispering gallery modes. These exceedingly small but detectable resonance shifts correspond to temperature increases of ~100 nK (measured at room temperature!), making their absorption spectrometer simultaneously one of the world’s best thermometers. Suprisingly, the nanorod’s absorption spectrum revealed a dense array of sharp Fano interferences arising from its interaction with the whispering gallery modes of the microresonator, allowing the team to deeply explore the hybridization of plasmonic and photonic cavity modes.
This collaborative effort brought together the creativity and talents of several graduate students and postdocs in multiple departments between the two institutions. The results were achieved following years of hard work involving both theorists and experimentalists. Future directions will explore the feasibility of this system to serve as a platform for studying quantum physics at room temperature.
