Weill Cornell Medical College, Cornell University

Dr. Nikolaos (Nicolas) A. Karakatsanis is currently Assistant Professor of Biomedical Engineering in the Radiology Department of Weill Cornell Medical College, Cornell University in New York, NY, USA. Dr Karakatsanis is also certified from the American Board of Science in Nuclear Medicine (ABSNM) with a specialty in Nuclear Medicine Physics and Instrumentation. Nicolas is also a Senior IEEE member and elected (3-year term, 2017-2020) in the Nuclear Medical Imaging Sciences Council (NMISC) of the IEEE Nuclear and Plasma Sciences Society (NPSS). Moreover, Nicolas currently serves as the elected intern (2-year term, 2017-2019) of the Computer and Instrumentation Council of the Society of Nuclear Medicine and Molecular Imaging (SNMMI).

Nicolas is aiming to enhance the diagnostic, prognostic and theranostic value of pre-clinical and clinical Positron Emission Tomography (PET) imaging for cardiovascular, oncologic and neurologic diseases. His main research focus has been the development of clinically feasible and quantitative PET/CT and PET/MR imaging methodologies, using:

  • PET/CT and simultaneous PET/MR clinical systems
  • novel and clinically adoptable whole-body dynamic PET acquisition protocols
  • multi-parametric dynamic dual-tracer PET/MR cardiovascular imaging methods
  • whole-body PET tracers kinetic modeling analysis coupled with robust kinetic parameter estimation techniques at the image voxel level
  • advanced 4D parametric PET/CT and PET/MR image reconstruction for enhanced molecular imaging quantification
  • data-driven respiratory and cardiac motion estimation and correction techniques within and after PET image reconstruction
  • synergistic PET/MR image reconstruction for partial volume error (PVE) correction
  • evaluation of Time-of-Flight (TOF), Continuous Bed Motion (CBM) and Resolution Modeling (PSF) technologies clinical benefit in specific PET/CT & PET/MR protocols
  • NECR-based PET dosage optimization

In the past, Dr Karakatsanis was appointed as a Senior Research Scientist at the Translational and Molecular Imaging Institute (TMII) at the Icahn School of Medicine at Mount Sinai, New York, NY, USA (July 2015 – Aug 2017), as a member of the Cardiovascular Imaging Lab led by the Director of the TMII, Prof. Zahi Fayad.

Between January 2014 and July 2015, Nicolas had received training as a Postdoctoral Research Associate at Geneva University Hospital (Hôpitaux Universitaires de Genève, HUG) after joining the PET Instrumentation and Neuroimaging laboratory (PINlab) led by Dr. Habib Zaidi, honorary professor also at the University Medical Center of Groningen (UMCG) in Netherlands.

Dr Karakatsanis also maintains an active and close collaboration with the Tomographic Image Reconstruction and Analysis (TIRA) lab led by Dr Arman Rahmim, Associate Professor of Radiology and Electrical and Computer Engineering at Johns Hopkins University.  In the past, Nicolas had been appointed at Johns Hopkins University Hospital as a Postdoctoral Research Fellow from February 2011 to December 2013.

Furthermore, Nicolas is working closely with the Nuclear Imaging Medical lab (NIMlab) and Dr George Loudos, Assistant Professor at the Biomedical Engineering Department of the Technical Educational Institute of Athens, Greece.
