Information Physics
Professors Caticha, Earle, Goyal, and Knuth
Information Physics is focused on the role that information plays in our understanding of the physical world  Foundations of Quantum Theory
Professors Caticha, Earle, Goyal and KnuthFoundations of quantum theory is concerned with identifying and formalizing the counterintuitive features of quantum theory (such as nonlocality and contextuality), and, more generally, in unravelling its implications for our conception of physical reality.
 Foundations of Inference
Professors Caticha, Earle, Goyal and KnuthFoundations of inference is concerned with the systematic development of mathematical tools that formalize the process of making reasonable inferences from limited information, and with developing an understanding of the conceptual foundations, interrelations, and domains of validity of existing tools (such as Bayesian inference and the Principle of Maximum Entropy).
 String theory and Particle Physics
Professor LuninTheoretical particle physics develops models and mathematical tools to understand properties of elementary particles and to make predictions for future experiments.

Mathematical Physics
Professor Inomata
Experimental Physics
 High Energy Physics
Professors Alam, Ernst and Jain
The high energy research group is a federally funded and active member of the ATLAS collaboration at CERN's Large Hadron Collider. Current work involves Higgs searches, Trigger software and Algorithms, and Muon reconstruction software. 
Electron Paramagnetic Resonance Spectroscopy
Professor EarleThe Earle group uses high field Electron Paramagnetic Resonance (EPR) to study the structure and dynamics of natural and artificial spin probes in systems of biophysical and chemicophysical interest. High field EPR can provide enhanced resolution of structural features analogously to high field Nuclear Magnetic Resonance (NMR). The Earle group has an active and ongoing collaboration with the ACERT National Research Resources Center at Cornell University.

Xray Analysis, Optics, and Imaging
Professor MacDonald
The Center for XRay Optics was founded by Professor Emeritus Walter Gibson in 1990 to investigate the science and technology of the newly invented Kumakhov poycapillary optics.  Material Physics
Professors Kuan and Lanford
The major theme of Prof. Kuan's research program is to study the microstructure of a wide variety of materials, including metals, semiconductors, superconductors, ceramics, and polymers. Prof. Lanford's research harnesses the 4MV ion beam accelerator located on the Albany campus, which offers unique capabilities for materials physics. Current research topics include: 1. clean surfaces, interfaces, and surfacesensitive properties of materials; 2. defects in solids; 3. hydrogen in solids.
Computational Physics

Bayesian Data Analysis
Professor KnuthBayesian data analysis focuses on applying Bayesian probability theory as well as maximum entropy techniques to develop highquality data analysis algorithms. We offer a senior/graduate level course on Bayesian Data Analysis every other year.

Cyberphysics and Robotics
Professor KnuthCyberphysics is the physics of informationbased control in systems that display a strong coupling between computing and control elements. Such systems are called cyberphysical systems. Here we investigate the fundamental physics governing the processes of informationdriven systems.

Computational optical modeling and imaging
Professor PetruccelliComputational optical modeling uses computational techniques to model the distribution of an optical field after spatial propagation or time evolution. Computational imaging makes use of digital sensors and computers along with optical system design to computationally recover properties of the optical field. Our work in computational modeling focuses on techniques to efficiently and exactly model wave propagation by using ray or particlelike models, making possible computations that were traditionally computationally prohibitive. Our work in computational imaging mainly focuses on techniques to recover properties of optical waves that are undetectable with traditional imaging, such as the thickness of nearly transparent objects or the spatial distribution of refractive index (a measure of the speed of light and attenuation in a material) in a volume. Our computational imaging work also includes collaborations with the Center for XRay Optics.
