AMRIS Faculty and Professional Staff

Barbara Beck has 20 years of experience designing and testing RF coils for MRI. She has built coils for a range of magnetic field strengths, from 0.15 T to 11.1 T, for clinical whole body systems and animal research systems. She has worked in the academic setting as well as the corporate environment. Most recently she has been a part of an NIH Resource Grant (P41 RR16105) to develop array technology and large volume resonators for the 11.1 T, 40 cm clear bore magnet at the University of Florida. Beck has several dozen publications on coil technology and regularly makes presentations at the annual meeting of the International Society of Magnetic Resonance in Medicine (ISMRM). Her poster, "Wave Behavior in Phantoms at 11.1 Tesla", presented at the 12th annual meeting of the ISMRM in Kyoto, Japan, received a ribbon in the EM Fields, Coils, and Hardware category and her poster "Comparison of Microstrips and Surface Coils at 11.1 T as Building Blocks for Phased Array Surface Coils" presented at the 13th Scientific Meeting of the ISMRM in Miami, received a ribbon in the Engineering category. Beck is currently a senior engineer in the AMRIS facility at the McKnight Brain Institute at the University of Florida.

Gary Blaskowski received his master's degree in physics from the University of Florida in 1994. He assists users with equipment related to imaging experiments and takes all users through magnet safety. He is responsible for routine maintenance and repair of imaging systems. He also schedules magnet time and confirms magnet usage. He is trained in animal handling, and is available as an imaging consultant.






Kelly Jenkins, engineering technician, builds and maintains prototype RF coils and provides additional user support through cryogen and NMR facilities maintenance.








David M. Peterson is a senior engineer with over 19 years of radio frequency (RF) experience and 11 years as an engineer in the field. His duties include RF coil design from 1.5 T to 21 T for imaging and spectroscopy and management of the 3 T human imaging facility located in the McKnight Brain Institute. A major focus of his career has been on engineering methods for MRI and RF coil design. Peterson graduated from Florida A&M University in 1995 with a bachelor's degree in electronics engineering technology. He received his master's degree in engineering from Newport University in California and is currently pursuing a Ph.D. in biomedical engineering at the University of Florida.

Daniel Plant received his B.S. and M.S. in chemistry from the University of Florida under Wallace Brey in 1987. Following stints with GE NMR Instruments and Bruker BioSpin, he settled back in at the McKnight Brain Institute and currently manages six spectrometers used for animal imaging, NMR microscopy, and high-resolution spectroscopy. Dan collected the first high-resolution 3D NMR experiment and holds patents in Multidimensional NMR Spectroscopy. He participated in the first gradient spectroscopy experiments at GE where he helped build the first 3-axis gradient probe for spectroscopy. His research interests include the microscopy and micro-imaging of marine creatures for their ability to provide simplified models of neural interactions. Targeted contrast agents are also under investigation with a specific interest in isotopic methods.

Jim Rocca is a senior chemist with AMRIS principally responsible for solution NMR applications on the facility's four vertical-bore spectrometers. He also occasionally advises about spectroscopic matters on AMRIS's horizontal-bore imaging instruments. Rocca ensures proper operation of the spectrometers, provides instruction for operators—particularly valuing chances to work closely with graduate students and postdoctoral associates, does a bit of troubleshooting and maintenance, and analyzes samples for users who are not able to provide their own operators. Prior to becoming an applications specialist with AMRIS (and previously with the university's Center for Structural Biology), Rocca's background was largely in organic chemistry. He received his undergraduate education at the University of Central Florida and graduate education in chemistry at Cornell University and the University of Florida. He has worked in academia, in state and federal governmental laboratories, and in light industry, and has experience in conventional organic synthesis; organo-metallic chemistry; natural products chemistry, especially of insects, high performance gas and liquid chromatography, including pesticide analysis; and infra-red, mass, and NMR spectroscopy. His favorite NMR experiments employ Nuclear Overhauser Effect Difference Spectroscopy. Rocca enjoys collaborative research opportunities and has recently published with a number of different research groups in Biochemistry, the Journal of Medicinal Chemistry, Journal of Magnetic Resonance, and others. The insect on Jim's shirt in the accompanying picture is a walking stick of the genus Anisomorpha. It produces venom that was extensively characterized in work with Aaron Dossey, Spencer Walse, and Art Edison, which should be published soon in ACS Chemical Biology.

Xeve Silver received his B.S. in psychobiology and molecular biology from the University of Miami. He spent four years as a senior biological scientist in Dr. Thomas Mareci's UF lab focusing on inductively coupled implantable RF coils and spinal injury related MR studies. Silver now works in the AMRIS facility as the scientific research manager, where he facilitates imaging and animal spectroscopy projects. His interests and duties include imaging protocol optimization and development, end-user training, animal research, cardiac imaging, new and novel imaging techniques, contrast mechanisms, and diffusion based studies.
