DMITRY NOVIKOV

Associate Professor

I am a faculty at the Department of Radiology, Center for Biomedical Imaging, New York University School of Medicine, where I spearhead the MRI Biophysics group, together with Els Fieremans. My background is theoretical condensed matter physics, which adds a unique perspective and modern physics methodology to quantifying tissue properties with diffusion and relaxation MRI at the mesoscopic scale of cell dimensions. 

RESEARCH INTERESTS

  • Biophysical modeling of diffusion and NMR transverse relaxation at the mesoscopic scale
  • Mapping of tissue microstructure with MRI
  • Parameter estimation in tissue models; information content of MRI signal
  • Image reconstruction and noise-removal techniques based on random matrix theory

PREVIOUS RESEARCH

I received a PhD in theoretical condensed matter physics from MIT Physics Department in 2003, and subsequently worked as research fellow at Princeton and Yale in 2003-2008. I developed elastic scattering theory [1] for electrons in graphene, a novel nanoscale material with unique electrical properties, and exactly solved the Coulomb scattering problem in graphene, which has explained the main observable contribution to its electrical resistivity [2]. I also introduced quantized adiabatic charge transport of a fractional quasipartlcle charge, which is relevant to carbon nanotubes and graphene nanoribbons [3, 4]. This transport mechanism involves a strongly correlated semi-crystallized one-dimensional ordering of electrons (the so-called Mott insulator, recently observed [5]), placed in the field of an adiabatically moving periodic potential. These strongly correlated electronic states are relevant for metrology (current quantization) and for quantum computing. I have also helped to reveal collective effects in arrays of quantum dots [6], which may explain non-Gaussian (Levy) statistics in their fluorescence.
