Sean McDarby Receives PhD

by


Dr. Sean McDarby

Dr. Sean McDarby recently defended his Ph.D and thesis entitled, “Synthesis and Measurement of Noble Metal Nanoparticles with Well Defined Shapes by Electrochemical and Electroless Approaches.” Sean started at Wesleyan University in 2015 after completing his BS in Chemistry at Southern Connecticut State University where he conducted research under Dr. Gerald Lesley. His undergraduate research focused on the synthesis of novel MOF precursors involving the manipulation of air-free inorganic pathways. Upon starting at Wesleyan University, Sean joined the research lab of Dr. Michelle Personick and began a project to develop a new method to electrochemically synthesize shaped noble metal nanoparticles. The project was quickly successful, and the method was transitioned into a cyclical tool to create shaped nanoparticles by collecting electrochemical data about any particle growth reaction and translate that to either an electrochemical or colloidal approach. Further work involved the creation of novel shaped nanoparticles, mostly with palladium in both systems. Having completed his degree at Wesleyan, Sean will be starting his career as a federal contractor for Universities Space Research Association at NASA Glenn Research Center in Cleveland, Ohio where he is joining the Microgravity Sciences division and is focusing on the production and applications of boron nitride for space and aeronautics.

Jozafina Milicaj Receives PhD

by


Dr. Jozafina Milicaj 

Dr. Jozafina Milicaj recently defended her Ph.D. and presented her work entitled, “Biophysical Exploration of Heptosyltransferase I for Potent Inhibitor Discovery.” Jozie started at Wesleyan University in 2015 after completing her BA in Chemistry at Manhattanville College where she was heavily involved with the American Chemical Society chapter and even holding the position as president for her senior year.  Jozie’s undergraduate research project was focused on analytical chemistry and the quantification of antioxidants from açaí berry sources through various extraction methods and UV-Vis radical capture assays. Upon starting at Wesleyan University, Jozie joined the research lab of Dr. Erika Taylor and began working on projects pertaining to Heptosyltransferase I substrate biosynthesis and optimization. Her projects then shifted to understanding and biophysically characterizing HepI and other glycosyltransferases like MshA for the purposes of inhibition of HepI. Having completed her degree at Wesleyan, Jozie will soon be starting her career in industry at Ginkgo Bioworks, a biotech company in Cambridge that professes in novel protein engineering where she will be characterizing and kinetically examining new proteins of interest.

“Dynamics of Computationally Designed Fluorescent Proteins”

The goal of the research is to study and optimize the movement of microscopic, computationally designed proteins that use light to track the locations of biological molecules and reveal how living organisms work. While the structure of a protein is almost always necessary for function, it is often not sufficient. This project focuses on the critical but often neglected role of protein motion in enabling absorbance and reemission of light, a process known as fluorescence. We will first determine which protein shapes either enhance or inhibit fluorescence through detailed analysis of computer simulations and extensive experimental structural characterization. Second, we will test our models through redesign and experimental examination of brighter fluorescent protein variants. As part of these efforts, we will develop a general-purpose computer algorithm that enables rapid evaluation of how thousands of potential mutations affect the shape of the protein. Third, we will investigate the structural determinants of other important properties like the ability of the protein to prevent or facilitate switching fluorescence on and off. The ultimate aim of this project is to develop a detailed understanding of how these fluorescent proteins can be redesigned to make them truly useful tools for biological research. This will enable the creation of even more advanced versions of these and other protein machines (like enzymes) that can also help in the manufacture and recycling of materials at the chemical level.

Chemistry Alumnus Jessica Garcia Awarded Eastman Chemical Company Fellowship

by

Jessica Garcia, a 2021 graduate of the BA/MA program in Chemistry, was recently awarded a fellowship through the University of North Carolina. The Eastman Chemical Company Fellowship program is a newly established award bestowed to first year graduate students at UNC for their committed effort to enhance the departmental mission to create a diverse and inclusive community. Sponsored by the Eastman Chemical Company, Eastman Fellows receive a stipend that supports the continuation of their contributions to the Carolina Chemistry community.  Jessica is among six students who were awarded this prestigious fellowship. Join us in congratulating her on this momentous achievement!

Personick Wins Silver (and more) at USRowing Masters National Championships

by


Dr. Personick & teammates

From August 12-15th, Prof. Personick competed at the USRowing Masters National Championships on Melton Lake in Oak Ridge, Tennessee. The weather was hot, but the water was flat and cold—perfect for racing and keeping cool. Her team, Riverfront Recapture, won medals in 46 events – 24 gold, 11 silver and 11 bronze – a team record. After a fog delay each morning, Prof. Personick raced to win one silver medal (women’s open B four with coxswain*) and three bronze medals (women’s club A four with coxswain, mixed AA four with coxswain, and mixed B eight). She also finished fourth in the women’s open A four with coxswain and fifth in the women’s open A single sculls.

All of these finishes contributed points to Riverfront’s success in the team points competitions. The team won the men’s points trophy and finished second for club points, third for overall points (out of 112 teams), and second for the efficiency competition (points per athlete). Overall, it was a great success, and the team is now looking forward to the fall racing season!

Dr. Benjamin Elling Joins the Chemistry Department

by

The Chemistry Department is delighted to welcome Dr. Benjamin Elling as an Assistant Professor of Chemistry. His recently renovated lab, in the space formerly occupied by Albert J. Fry, will investigate new methods to synthesize and reprocess polymers. This semester he will be teaching CHEM 373, an upper-level course on polymer chemistry.

Professor Elling received his BA in chemistry from Cornell University, where he synthesized polymers for anion exchange membranes in the lab of Geoff Coates. He then attended Stanford University, where he became the first PhD student of Yan Xia and developed methods for sequence-specific polymerization via the ring-opening metathesis of substituted cyclopropenes. Prior to his appointment at Wesleyan, Professor Elling was a postdoctoral scholar in the lab of Professor Will Dichtel, where he designed new covalent adaptable networks and investigated strategies for mixed plastic compatibilization.

Here at Wesleyan, Professor Elling will combine his interests in synthetic methods development and sustainability. His lab will focus on leveraging strain energy to create polymers capable of controlled degradation, reprocessing thermosets through novel exchange chemistries, and incorporating renewable building blocks such as carbon dioxide into materials. The Chemistry Department is very pleased to have him join us.

Andrea Lee Receives PhD

Dr. Andrea Lee

Dr. Andrea recently defended her Ph.D. dissertation entitled “Examining Chromium(III)-based Contrast Agents for Use as a Model for Understanding Prototropic Exchange in ParaCEST MRI Contrast Agents.” Andrea started at Wesleyan University in 2014 after graduating with honors from the University of New Haven where she received a B.S. in Forensic Science and a B.S. in Chemistry. Her undergraduate thesis work focused on analyzing the triglycerides in biofuel made from acorns using HPLC with detection by FT-IR and UV-Vis. Upon starting at Wesleyan University, Andrea joined the research lab of Professor Westmoreland and worked on many research projects exploring various transition metal-based MRI contrast agents and their properties in aqueous solutions. She also received many opportunities as a teaching assistant which included taking on many responsibilities in the Introductory Chemistry Laboratory. She was also awarded the Tishler Teaching Award in 2018. This fall, Andrea will be starting as an Assistant Teaching Professor at Drew University where she will be teaching Analytical Chemistry.
