She has also been a Reviewer for proposals submitted to DOE (Department of Energy), Basic Energy Sciences, and to NSF (National Science Foundation) for the Division of Materials Research, the Program on Condensed Matter Physics, the Program on Inorganic Chemistry, the Program on Bioinorganic and Organometallic Chemistry, and the Program on Polymer Science. She has been with the Panelist and served in review panels for the National Science Foundation, Division of Materials Research, PIRE (Program in International Research and Education), SBIR (Small Business Innovation Research), the Program on Inorganic, Bioinorganic and Organometallic Chemistry, and MRI (Major Research Instrumentation). She served as a Peer Evaluator of the scholarly records of individuals considered for tenure or promotion at Villanova and other universities, in the USA and abroad, and as an External Evaluator. She directs the Mössbauer Spectroscopy Laboratory at Villanova University. She supervised the operation of 8000M Mixer/Mill ball-milling machine for the production of ferrite nanoparticles via mechanochemical synthesis of dry nanopowders and magnetic ferrofluids through surfactant assisted ball milling. She has been a Reviewer of a new physics text published by Addison Wesley, Physics for Scientists and Engineers, A Strategic Approach, by Randall D. Knight, of the California Polytechnic University, and a companion online tutorial service, CyberTutor. Her areas of research are within condensed matter physics intellectual merit, which is a broad area of scientific inquiry that cuts across strict disciplinary boundaries to encompass areas of physics, chemistry, biology, and materials science and engineering: (1) cluster science and the transition from molecular to bulk behavior with increasing cluster size; (2) nanoscale magnetism, fundamental studies, and applications to nanotechnology and nanomedicine; (3) multiferroic materials; (4) iron proteins, iron metabolism, and iron disorders. She is also interested in studying nanoscale magnetism: the molecular/solid-state boundary matter of nanoscale dimensions exhibits novel physical properties (electronic, magnetic, and optical) that lie between those of atomic and molecular systems and the bulk state of solids. The magnetic properties of large molecular clusters and nanometer size particles are being investigated, in order to probe the transition from atomic-scale to bulk magnetism and fundamental properties of magnetic nanolattices. She focuses on magnetic ferrofluids, magnetic /quantum-dot, and magnetic/noble-metal hybrid nanostructures: the magnetic properties of isolated magnetic nanoparticles and their assemblies are investigated in novel structures of well-controlled composition and high crystallinity. Novel magnetic ferrofluids for hyperthermia cancer treatment are also studied. She studies multiferroic nanoparticles: coupling of electric, magnetic, and structural order parameters give rise to simultaneous ferroelectricity, ferromagnetism, and ferroelasticity. She has been focusing on the biological iron utilization: biomineralization in recombinant and mutant ferritins: iron is a required element necessary as an enzyme cofactor and as a substrate for heme biosynthesis. The mechanism of oxidative iron deposition in wild-type, recombinant, and mutant ferritins, iron nucleation and polymerization processes, and the structural and magnetic properties of the resulting nanobiomineral cores are under investigation. Additionally, the iron-induced protein aggregation in ferritins containing the mutant L-chain variant 460InsA (Mt-FTL) is being investigated. She also focuses on the interparticle interactions in core/shell iron oxide nanoparticle assemblies: magnetic relaxation in nanoparticle assemblies is poorly understood due to complex long-range, dipole-dipole (d-d) interactions. She has a broader impact to society, research, and education as the basic research on recombinant and mutant ferritins impacts on the understanding of iron-related diseases, cytotoxicity, and the molecular bases of neurodegenerative disorders characterized by abnormal accumulation of iron in the central nervous system. She has collaborated with many esteemed professors and scientists. Among her invited talks and conference presentations (since 2007) are “Magnetic Relaxation Processes in Functionalized Iron Oxide Nanoparticles and Their Assemblies” to be presented at the 244th American Chemical Society National Meeting, Symposium on Functionalized Nanoparticles for Biomedical Applications, August 19–23, 2012; “ Micromagnetic Characterization of Functionalized Iron Oxide Nanoparticles and their Assemblies,” presented at DECHEMA‘s Conference “Nanomaterials for Biomedical Technologies 2012” March 6-7, 2012, Frankfurt, Germany; “Spin Dynamics in Recombinant H-Chain Ferritin Reconstituted with 500Fe/Protein” presented at the American Physical Society March Meeting, 2012, Boston, Mass, USA; “Enhancing the Multiferroic Properties of BiFeO3 at the Nanoscale,” presented at the Materials Research Society Meeting, November 28 to December 2, 2011, Boston, Mass, USA; “Synthesis and Characterization of Nanoparticulate Magnetic Materials” Invited Tutorial Talk BuildMoNa Workshop, Department of Physics, University of Leipzig, Leipzig, Germany, October 28-29, 2010; Invited Talk at the summer school titled “Micro-Nanotechnology and Nanobiotechnology” organized by Nano2Life (the first European Network of Excellence in the field of nanobiotechnology), Athens, Greece, July 2007 and July 2008; this Plenary lecture may be viewed in video available in e-learning section of the Nano2Life (Bringing Nanotechnologies to Life) website: http://www.nano2life.org/.
