Professor Linda Doerrer and fourth year graduate student, Steven Hannigan, were chosen as recipients of a Boston University Ignition Award. This program provides funds to validate early-stage research projects with clear commercial potential.
The Doerrer group has determined that a fully fluorinated copper(II) compound can electrocatalytically reduce nitrate in water. Such a technology would be extremely relevant to today’s market for water treatment systems because it addresses an increasingly significant environmental problem. Nitrate is a common component in all man-made fertilizers and is, therefore, increasingly found in all salt- and fresh-water bodies. The nitrate is a fertilizing food source for microorganisms whose excessive growths are called harmful algal blooms (HABs), which can lead to aqueous “dead zones” in rivers, seas, and lakes that can be seen from satellites.
The Ignition Award Program was launched in 2007 by the Boston University Office of Technology Development. Since then, it has issued 46 awards, 10 of which have been given to Chemistry faculty to advance their innovative ideas.
Chemistry faculty, John Snyder and Binyomin Abrams, in conjunction with colleagues in the Departments of Biology (Kathryn Spilios and John “Chip” Celenza) and Neuroscience (Paul Lipton and Lucia Pastorino) have successfully proposed ideas to develop integrated, inquiry-based laboratory courses for first and second year biology, chemistry, and neuroscience students. Jointly funded by the Office of the Provost, the Center for Excellence & Innovation in Teaching, and the College of Arts and Sciences, these interdisciplinary course development grants aim to promote faculty and student collaboration across disciplines in support of innovative, research-oriented undergraduate laboratory education. The new courses that are being developed, Integrated Science Experience 1 (ISE 1) (for second semester freshmen) and ISE 2 (for first semester sophomores), will facilitate students making connections across biology, chemistry, and neuroscience early in their undergraduate careers. Such interdisciplinary insights will better prepare for advanced courses and undergraduate research. Developed in 2015, the courses are anticipated to start in the Spring 2016, and Fall 2016 terms, respectively.
Every year, as the academic year draws to a close, Boston University honors a number of faculty for their outstanding work in the classroom and with their students with the Metcalf Award for Excellence in Teaching. This year, Senior Lecturer in Chemistry, Dr. Binyomin Abrams, has received Boston University’s top teaching award.
Dr. Abrams investment in the advancement of his students influences all of his activities as an educator, including making chemical education his primary research pursuit. In his second year at BU, he received the College of Arts and Science’s 2010 Templeton Prize for Excellence in Student Advising. In the area of chemical education, he has developed, both with colleagues and independently, a number of programs to improve Boston University’s level of chemical education and to provide his students with the best possible science learning experience. This year, he and colleagues in Chemistry, Biology, and Neuroscience successfully competed for Office of the Provost grants to develop integrated, inquiry-based laboratory courses for first and second year Biology, Chemistry, and Neuroscience students. These interdisciplinary course development grants will generate faculty and student collaboration across disciplines in support of innovative undergraduate education.
Dr. Abrams received his PhD from New York University and does research in molecular dynamics with a focus on the development of computational models for biomimetic foldamers. In the area of education, he has developed and run the BU Chemical Writing Program, which introduces Chemistry students to research-based writing in the context of inquiry-based chemistry laboratory courses. Additional projects have included the development of workshops to help incoming undergraduates succeed in the sciences; preparing hybrid, partially “flipped” activities for out-of-class student engagement in introductory chemistry courses; and the continued expansion of the freshman year chemistry lab alternatives to the honors freshman chemistry lab.
Dr. Abrams is the sixth Chemistry faculty recipient since the award was established in 1974. Previous recipients have included:
Professor Emeritus Richard Laursen‘s research on the analysis of vegetable dyes has taken him to many parts of the world. Using high-performance liquid chromatography with diode array and mass spectrometric detection, his work has helped to identify the plant sources of many of the colors used in ancient textile fibers and given insights into the stability of colors over time. His research expertise first took him to Iran in 2005, where he had the opportunity to examine antique rugs in the private collection of Miri Iranian Knots, a leading producer of handmade rugs since 1820.
This April, Professor Laursen returned to Iran to give a lecture on the “Analysis of Dyes in Ancient Textiles” at several universities and museums in Iran, including Islamic Azad University, Scientific Research Branch (Tehran); Islamic Azad University, Zanjan Branch (Zanjan); University of Zanjan (Zanjan); Tabriz Islamic Art University (Tabriz); Astan Quds Razavi Museum (Mashhad); and the Hakim Sabzevari University (Sabzevar). Professor Laursen noted many changes in the decade since he last went to Iran, including the increasing number of women college students.
Dr. Sarah Chobot Hokanson, who was a Chemistry major (CAS ’05) doing undergraduate research with Professor Sean Elliott, has returned to BU as Director of the newly launched Professional Development and Postdoctoral Affairs. Sarah and her new role are profiled in BU Today’s in-depth article “Helping Postdocs Take Charge of their Lives” (Sara Rimer). The article also details Sarah’s plans for assisting BU graduate students and postdoctoral fellows launch successful careers.
A highly trained scientist in her own right (PhD from the University of Pennsylvania, 2010, and NIH NRSA postdoctoral fellowship at Cornell, 2010-2012), Sarah started her own non-traditional science career path at the British Consulate-General in Boston as a senior officer for the Science and Innovation Network). Now back at BU, her real-time views can be followed on her twitter account.
2015 NSF Graduate Research Fellowship Program (GRFP) award recipient, George Pantelopulos, has joined Chemistry to do his proposed graduate research in theoretical chemistry with Prof. John Straub and his group. George aims to model the kinetics of phase transitions in a system of components (lipids and cholesterol) commonly found in eukaryotic cell membranes using the Generalized ReplicaExchange Method (gREM) developed by the Straub group and constructing a Markov State Model (MSM) of a mixed bilayer. George believes that his study will yield a statistically detailed model of the thermodynamics and kinetics of mixed bilayer phases, something which has been sought for years via experimental techniques and previously out-of-reach for standard simulation methods.
George is no stranger to BU Chemistry. In 2013 he was one of the 10 students selected for Chemistry’s NSF site Research Experience for Undergraduates (REU) program. At the time, he was at the Community College of Philadelphia. During his summer REU program here, he helped to synthesize nanohoops of high electron density, which were hypothesized to serve as high performance coatings for solar cells. In Fall 2013 he transferred to Temple University (Philadelphia, PA), where he did research with Prof. Vincent Voelz on simulation studies of the p53-MDM2 complex. MDM2 is an ubiquitin ligase protein which downregulates the tumor suppressor protein p53. As such, inhibition of the p53-MDM2 complex is a major goal in targeted cancer therapy research.
In addition to chemistry, George’s interests are broad and varied. He has a strong commitment to community service and have volunteered with such organizations as TeenSHARP, a weekend educational program for minority students in Philadelphia and Camden schools, where he was a science instructor and Habitat for Humanity.

At the Consumers Union, which she joined in 1999, she has been responsible for managing risk analysis, policy assessments, label evaluations and consumer advice for tests, reports, and related advocacy work. She developed the ratings system, database, and Web site, Eco-labels.org, for evaluating environmental and food labels. In 2005, she managed the launch of GreenerChoices,org, which covers green aspects over a wide range of products and services. To “meet” Dr. Rangan, please go to her 2012 TEDxManhattan talk, “From fables to labels.”
We are happy to announce that Arturo José Vegas will be joining the Department on July 1 as Assistant Professor. His research will aim to develop novel targeting therapeutics and delivery systems for selective cancer chemotherapy, immunomodulation, and diabetic immunosuppression. At the same time, the Vegas laboratory will create a general and systematic approach to developing targeted therapeutic carriers for treating multiple human diseases.
Arturo Vegas brings his unique training and experience in integrating chemistry and the biomedical sciences to come to bear on key challenges in medicine. He received his Ph.D. from Harvard University (2008) working with Professor Stuart Schreiber (Department of Chemistry & Chemical Biology). In the Schreiber laboratory, he adapted synthetic chemistry pathways developed in studies of diversity-oriented synthesis (DOS) to new pathways with clinical impact for cancer treatments aimed at targeting chromatin-modifying enzymes in human cells.
His postdoctoral training was in the laboratories of Professor Robert S. Langer and Professor Daniel G. Anderson both at the David H. Koch Institute for Integrative Cancer Research at MIT and Children’s Hospital Boston. Dr. Vegas’ research exploited the potential of chemical discovery in biomedical research. He applied chemical methods to modify polymers used in the encapsulation of islets, which is a promising approach for the treatment of type-1 diabetes. As a synthetic chemist, he prepared multiple libraries and unique chemical entities to facilitate siRNA delivery, a technology that is actively being explored for cancer treatment.
Dr. Vegas is already co-author on 20 publications and co-inventor of 8 patent applications as he begins his independent career at Boston University. He is also the Scientific Co-Founder of Preceres LLC (December 2013). His research was featured in Nature Medicine’s “Encapsulate This” (2014). As an educator, he was a multiple-year recipient of Harvard University’s “Distinction in Teaching” Award.
The College of Engineering has honored interdisciplinary scientist, Professor Mark Grinstaff (Chemistry, BME, MSE, MED), with the inaugural Charles DeLisi Award and Distinguished Lecture. Professor Grinstaff will present the Lecture on Thursday, April 2 at 4 p.m. in the Photonics Colloquium Room (PHO 906). In the lecture, “Clinically Informed Biomaterial Design and Engineering,” he will explore how over the past two decades, he and his students have translated ideas from the laboratory into new devices and materials for clinical applications.
The award – established by a generous gift by Professor and Dean Emeritus Charles DeLisi, widely considered the father of the Human Genome Project – is in recognition of Mark Grinstaff’s significant contributions to his field, both as an academic researcher and as an entrepreneur who has co-founded four companies that are translating his ideas into clinical products. In addition to his joint appointments in Chemistry and Biomedical Engineering, Professor Grinstaff directs the Center for Nanoscience and Nanobiotechnology (CNN) and an NIH-funded Translational Research in Biomaterials Training program, and is the inaugural College of Engineering Distinguished Professor of Translational Research and inaugural recipient of the Innovator of the Year Award from BU’s Office of Technology Development. He was also named a College of Engineering Distinguished Faculty Fellow and a Kern Faculty Fellow.
The Grinstaff laboratory, which is currently comprised of more than 20 graduate students and postdoctoral fellows, is funded by the National Institutes of Health, National Science Foundation, The Wallace H. Coulter Foundation, Advanced Energy Consortium, the Center for Integration of Medicine & Innovative Technology, and other agencies. They have advanced several major biomaterials that range from a joint lubricant that could bring longer- lasting relief to millions of osteoarthritis sufferers, to a highly absorbent hydrogel that not only seals wounds, but can later be dissolved and gently removed.
The National Science Foundation’s on line magazine, Science Nation, is featuring a video entitled “Biophotonics poised to make major breakthroughs in medicine.”
