American Chemical Society Division of Inorganic Chemistry Travel Award Winner

Congratulations to graduate student Scott Pierce (Angeles-Boza Group) for winning the American Chemical Society Division of Inorganic Chemistry (ACS-DIC) Travel Award. This program supports graduate students intending to present research talks or posters at ACS National Meetings.

Scott will also be presenting in the ACS Spring 2021 (to be held online from April 5 – 30). He will be presenting his work on “Peptide-Ruthenium Conjugate as an Efficient Photosensitizer for the Inactivation of Multidrug Resistant Bacteria.”

NSF Graduate Research Fellowship Recipient

Congratulations to graduate student Caroline Donaghy (Angeles-Boza Groupfor being awarded the prestigious NSF Graduate Research Fellowship. The NSF Graduate Research Fellowship Program (NSF GRFP) recognizes and supports outstanding graduate students in NSF-supported STEM disciplines.

Caroline will be working on developing green pesticides using glycopeptides throughout her fellowship.

Mani Group Paper Published in JACS

A new paper from the Mani Group appeared in the Journal of the American Chemical SocietyJason Buck, a 4th year graduate student, and Dr. Tomoyasu Mani demonstrated a new type of magnetic control of molecular emission. They take advantage of the quantum mechanical nature of radical pairs (pairs of radical anion and cation or molecular qubits) to control fluorescence by using weak magnetic fields and tune the field response range. The results present a new strategy for designing magneto-optical probes for imaging and give insights into molecular designs for spintronics and other molecular spin technology applications.

The research is funded by the Japan Science and Technology Agency, PRESTO, Creation of Life Science Basis by Using Quantum Technology.

A Message from the Department Head

Dear All,

Welcome to a new semester! The campus and building have come alive once again. We are welcoming new faculty and graduate students to the Department, we have awards and a retirement to celebrate, and we have a large group of students eagerly lining up for general or organic chemistry classes. Alas, this is not going to be a normal semester. Almost everything will be very different and difficult in ways that are predictable and unpredictable. Continue reading

Bird Eggshells Just Became More Colorful

Two eggs showing novel eggshell pigments: guacamole green and purplish-brown of two tinamous speciesFor well over 100 years, only two pigments have been identified in avian eggshells: rusty-brown protoporphyrin (e.g., brown chicken eggs) and blue-green biliverdin (e.g., turquois eggs of robins). However, tinamou (chicken-like forest dwellers of South America) eggshells display unusually colored eggshells, suggesting the presence of other pigments. The Brückner Group, in collaboration with the ornithologists and eggshell and bird color experts Daniel Hanley (Long Island University) and Richard Prum (Yale University), investigated this. Through extraction, derivatization, spectroscopy, chromatography, and mass spectrometry, they identified two novel eggshell pigments: yellow–brown bilirubin and red–orange uroerythrin from the guacamole-green and purplish-brown eggshells of two tinamous species. Both pigments are known porphyrin catabolites and were found in the eggshells in conjunction with biliverdin. A colour mixing model using the new pigments and biliverdin reproduced the respective eggshell colours. These discoveries expand our understanding of how eggshell colour diversity is achieved. The ability of these pigments to photo-degrade may have an adaptive value for the tinamous – this is the subject of follow-up studies for the ornithologists.

Matthew Howell Awarded NSF Graduate Research Fellowship

Matthew HowellCongratulations to Ph.D. candidate Matthew Howell, the recent recipient of a prestigious NSF Graduate Research Fellowship. This fellowship will begin in Fall 2020 and continue through Spring 2023. Given the growing crisis of antibiotic resistant bacteria, Matthew—in collaboration with advisor Dr. Alfredo Angeles—is interested in examining the relationships between peptides, metal ions, and antibiotics. Together, they are searching for combinations that demonstrate synergistic killing of these bacteria.

When a Distraction Becomes a Dissertation

In 2018, C&EN invited graduate students to submit essays about some aspect of their graduate experience for inclusion in the cover story “The Chemistry Graduate School Experience.” Now, C&EN continues to share diverse graduate student experiences.

The following perspective is provided by Ph.D. candidate Jessica Martin.


Jessica Martin“I may not get a Ph.D. in chemistry. After passing my qualifying exam and winning a National Science Foundation Graduate Research Fellowship, I was able to plunge into my thesis project. That was when I discovered that I found my project uninspiring and began seeking out distractions. One distraction was analyzing safety and hazard assessment within the work of chemists. I have struggled with the dissonance between industry calls for strong safety cultures and the revelations of disastrous industry misconduct. This prompted questions about how academia prepares Ph.D. chemists, what skills are emphasized, and how hazard assessment of the chemicals we create should be included.

As I have pursued these ideas, I have had enthusiastic discussions with people throughout the chemical world who believe this work is necessary. I have gained fantastic mentors eager to engage in ways I never experienced with my previous project. This work became my focus, leaving no time for my official project.

My department has been remarkably supportive as I have changed my thesis to hazard assessment and peer-to-peer education within a graduate program. However, there is a debate brewing over what my thesis will look like come judgment day. There is the distinct possibility that it will be determined that this work does not add up to a Ph.D. in chemistry. Even if it does not, I will walk out with a body of work of which I am immensely proud and connected to a community that is doing work that inspires me.”

Research Safety Workshop

The Department of Chemistry held their 2020 Research Safety Workshop for first year graduate students and Laboratory Safety Officers (LSOs) on Wednesday, January 15.  The Workshop was organized by the Department Safety Committee and the Joint Safety Team (JST) in conjunction with EH&S. Presentations were made by Dr. Jing Zhao (Chair of the Department Safety Committee), Jessica A. Martin (Head of JST), Eric Krantz (Head of Teaching Laboratory Services), and Brent Lewchik (Chemical Safety Manager, EH&S).  In all, 44 students were in attendance. A survey revealed that the vast majority of attendees found the material covered to be useful.
