Professor Mark Grinstaff and postdoctoral scientist, Dr. Aaron Colby, have received a 2015 Ignition Award from the BU Office of Technology Development to develop a nanoparticle-based drug delivery system for the treatment of mesothelioma.  Mesothelioma is a rare form of cancer that develops from cells of the mesothelium, the protective lining that covers many of the internal organs of the body.

The purpose of the Ignition Awards program is to validate early-stage projects with clear commercial and medical  potential.  This project was selected because, to date, there is no effective cure for mesothelioma and there is no way to prevent local recurrence. In this research, the Grinstaff group is  developing a novel nanoparticle-based drug delivery system for localizing intraperitoneally administered chemotherapy directly to the site of established disease that remains following surgical resection procedures.  The result is increased tumor-tissue drug concentrations and, subsequently, reduced recurrence and improved patient survival.

Since its establishment in 2007, the Ignition Awards Program has funded 46 project.  Of these projects, 10 have been developed by Chemistry faculty.

Reunion of Undergraduate Chemistry Researchers

June 3rd, 2015 in Alumni, Uncategorized

Three undergraduate students from the early 1970’s met their research advisor, Professor Emeritus Morton Z. Hoffman, and his wife, Sandy, recently for dinner at the Post 390 restaurant in Boston. The students were co-authors with him on a publication, “Generation of Radicals in the Charge-Transfer Photochemistry of Coordination Complexes of Cobalt(III) in Aqueous Solution,” J. Phys. Chem., 78, 686-691 (1974).

Deborah (Campano) German (CAS ‘72) was also a student in Hoffman’s CH101-102 lecture section in 1968-69. She received an M.D. degree from Harvard University and is now Dean of the College of Medicine and Vice President for Medical Affairs of the University of Central Florida in Orlando. She was married to fellow chemistry alumnus, Larry German (CAS ‘72), who passed away some time ago.

Evan (Rick) Kantrowitz (CAS ‘71), who took CH111-112 with Professor John Endicott in 1967-68, just retired as Professor Emeritus after a 37-year career in the Department of Chemistry of Boston College. He received a Ph.D. from Harvard University with Bill Lipscomb as his research supervisor. His wife, Ellen, accompanied him.

Innovative research by Prof. Linda Doerrer and her student, Steven Hannigan, will be advanced by BU Ignition Award

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.

Interdisciplinary, Integrated Course Ideas Receive Provost Grants

May 21st, 2015 in Uncategorized, Undergraduate

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.

Former Chemistry REU student, George Pantelopulos, returns as Graduate Student

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.
