Physics Research Areas
Research Interests: Brent McDaniel's research focuses primarily on large scale, extratropical atmospheric dynamics. One facet of this work is the study of stratosphere-troposphere interaction. This examines the role of the stratosphere in influencing tropospheric climate and short-term surface variability (weather). Another facet of this work is the study of annular (disk-like) modes. Recent work has shown that the atmosphere has preferred states that can be characterized as annular modes. Much of the intraseasonal variability seen in the stratosphere can be explained by examining just a few of these modes. Another facet of this work involves assessing the ability of global climate models to accurately and realistically simulate atmospheric annular modes and the physical mechanisms that produce them.
Research Interests: With secondary school diplomas from both a scientific lyceum in Florence Italy and a high school in Miami Beach and college enrollment in places as disparate as the University of California and the University of Bologna, David Garofalo's academic record is a reflection of multiple interests. Following several years playing soccer in Italy's lower divisions, he obtained his Ph.D. in physics from the University of Maryland where he developed interest, and currently conducts research, in black hole astrophysics. Following postdoctoral work as a NASA fellow at the Jet Propulsion Laboratory in Pasadena, and several years of teaching at various California schools including the California State University, he moved to Columbia University in New York. He is now Assistant Professor in the Department of Physics at Kennesaw State.
Experimental Particle Physics
Experimental Particle Physics is the study of the detection and measurement of the basic particles which make up the material world at its most fundamental level. These fundamental particles include the six quarks and the composite particles formed from their combinations (such as the proton and the neutron), the three charged leptons (including the electron), the three neutrinos, the gauge bosons (the photon, W, Z, and gluon) as well as the Higgs Boson. These particles make up the Standard Model of particle physics, and detailed measurement of their properties is one of the goals of the field, along with searches for new and undiscovered particles beyond the Standard Model.
The Kennesaw State Experimental Particle Physics research area focuses on precision measurements of rare decays of the b and c quarks; since 2012 Kennesaw State has been a member institution of the Belle and Belle II collaborations which are dedicated to performing these particular measurements. The Belle and Belle II collaborations are based at the KEK Laboratory in Tsukuba, Japan; both of these collaborations are made up of laboratories and universities from around the world.
Research Interests: Over 20 years research experience in data analysis and experimental high-energy physics, including projects at CERN (Switzerland), Fermi and Brookhaven National Laboratories (USA), TRIUMF (Canada) and KEK (Japan) - I am currently affiliated with the Belle and Belle II experiments at KEK.
Research Interests: Dr. Kulasiri's primary research area is Experimental High Energy Particle physics. He is currently affiliated with BELLE and BELLE II experiments, located at High Energy Accelerator Organization (KEK), Tsukuba, Japan. BELLE and BELLE II experiments study the CP violation of B mesons. In addition to that precise measurements of CKM parameters, studies of rare decays, physics beyond the Standard Model and search for new exotic particles are some of the research experiments that have been carried out.
Materials Physics is the study of solid materials for both a fundamental understanding of the relationship between the composition, structure and properties of the materials as well as for their potential technological applications. Our research includes the synthesis and analysis of amorphous materials (like glass), semiconductors, metals, composites and even polymers. These materials are being studied for applications in energy conversion, biology, magnetics, and optics.
Research Interests: My primary research interests involve the study of structure property relationship in technologically important magnetic and dielectric materials. In particular my research focuses on two aspects of non centrosymmetric (materials that lack center of inversion in their crystal structure) materials. Those two aspects are (i) dielectric properties (ii) magnetic properties.
Research Interests: Dr. Ranasinghe is conducting research on glass science and technology under several different topics. She mainly work in silica based binary and ternary glasses under the following topics: 1) Nucleation and crystallization using differential thermal analysis. 2) Rigidity transition in silicate glass systems using modulated differential scanning calorimetery. 3) Containerless processing of silica glass using an electrostatic levitator (NASA MSFC).
Research Interests: Professor Stokes currently investigates the thermal and electrical properties of nanocomposite materials including semiconductor/metal nanocomposites and nanoparticle polymer composites for thermoelectric and pyroelectric applications. A nanocomposite is a material which contains nanometer-sized inclusions or a material made from the assembly of two or more nanoparticle compounds. Our investigations help us to understand the transport of heat and electricity in semiconductors and metals and what effect, if any, do the nanometer-scale dimensions have on these properties.
Research Interests: Dr. Gulley's research is centered on the physics of nonlinear laser-pulse propagation. It consists mainly of simultaneous numerical modeling of both laser-pulse propagation and laser-material interactions on the femtosecond time scale. His work has significant impact for applications involving laser-induced damage, remote sensing, micromachining, and nanofabrication of dielectrics and semiconductors. Dr. Gulley and his collaborators are also developing new models for the interaction of intense multi-chromatic lasers fields with transparent solids.
Theoretical Particle Physics
Research Interests: The research of Professor Nikolaos Kidonakis is in theoretical particle physics, mainly in top quark production, Higgs and W production, perturbative Quantum Chromodynamics, and high-energy phenomenology at hadron colliders. Professor Kidonakis' work has significantly advanced the calculations of higher-order corrections and has received international recognition and many thousands of citations. His results have been widely used by experimental collaborations at high-energy colliders for comparing theory and experiment for several processes, most notably top quark production at the LHC and the Tevatron.
Research Interests: The research of Dr. Guzzi is in Theoretical Elementary Particle Physics and in many areas of High Energy Physics. His work involves calculations in Quantum Field Theory, Computer Simulations and Statistical Analysis of Experimental Data. Dr. Guzzi investigates quantum field theory of the strong interactions (Quantum Chromodynamics) and Hadron Collider phenomenology with a special focus on precision physics at the Large Hadron Collider (LHC). He is an expert in analyses of the structure of the proton, in particular parton distribution functions (PDFs) of the proton, and in perturbative calculations for vector boson, top-quark pairs, and QCD jet production at the LHC. Dr. Guzzi extensively worked on Physics Beyond the Standard Model and tested predictions of several extensions of the Standard Model at the LHC to investigate possible signatures of New Physics.
