  Current Research and Scholarly Interests Myocardial bridges (MB) with associated upfront atherosclerotic lesions are common findings on coronary computed tomography angiography (CTA). Abnormal septal wall motion in exercise echocardiography (EE) may to be associated with MB. Intravascular ultrasound (IVUS) is considered the gold standard for the detection of MB. We investigate whether CTA is comparable to IVUS for the assessment of MB and upstream plaques in symptomatic patients with suspicion for MB raised by EE.

  Frederick T. Chin, Ph.D.

  Assistant Professor (Research) of Radiology (General Radiology)

  Current Research and Scholarly Interests Our group's primary objectives are:
  
  1) Novel radioligand and radiotracer development.
  We will develop novel PET (Positron Emission Tomography) imaging agents with MIPS and Stanford faculty as well as other outside collaborations including academia and pharmaceutical industry. Although my personal research interests will be to discover and design of candidate probes that target molecular targets in the brain, our group focus will primarily be on cancer biology and gene therapy. In conjunction with our state-of-the-art imaging facility, promising candidates will be evaluated by PET-CT/MR imaging in small animals and primates. Successful radioligands and/or radiotracers will be extended towards future human clinical applications.
  
  2) Designing new radiolabeling techniques and methodologies.
  We will aim to design new radiolabeling techniques and methodologies that may have utility for future radiopharmaceutical development in our lab and the general radiochemistry community.
  
  3) Radiochemistry production of routine clinical tracers.
  Since we also have many interests with many Stanford faculty and outside collaborators, our efforts will also include the routine radiochemistry production of many existing radiotracers for human and non-human use. Our routine clinical tracers will be synthesized in custom-made or commercial synthetic modules (i.e. GE TRACERlab modules) housed in lead-shielded cells and be distributed manually or automatically (i.e. Comecer Dorothea) to our imagers.

  Christopher H. Contag

  Professor of Pediatrics (Neonatology), Emeritus

  Current Research and Scholarly Interests We develop and use the tools of molecular imaging to understand oncogenesis, reveal patterns of cell migration in immunosurveillance, monitor gene expression, visualize stem cell biology, and assess the distribution of pathogens in living animal models of human biology and disease. Biology doesn't occur in "a vacuum" or on coated plates--it occurs in the living body and that's were we look for biological patterns and responses to insult.

  Hongjie Dai

  The J.G. Jackson and C.J. Wood Professor in Chemistry

  Bio Professor Dai’s research spans chemistry, physics, and materials and biomedical sciences, leading to materials with properties useful in electronics, energy storage and biomedicine. Recent developments include near-infrared-II fluorescence imaging, ultra-sensitive diagnostic assays, a fast-charging aluminum battery and inexpensive electrocatalysts that split water into oxygen and hydrogen fuels.
  
  Born in 1966 in Shaoyang, China, Hongjie Dai began his formal studies in physics at Tsinghua U. in Beijing (B.S. 1989) and applied sciences at Columbia U. (M.S. 1991). His doctoral work under Dr. Charles Lieber at Harvard U. (Ph.D. 1994) focused on charge-density waves and superconductivity. During postdoctoral research at Rice U. with Dr. Richard Smalley, he developed carbon nanotube probes for atomic force microscopy. He joined the Stanford faculty in 1997, and in 2007 was named Jackson–Wood Professor of Chemistry. Among many awards, he has been recognized with the ACS Pure Chemistry Award, APS McGroddy Prize for New Materials, Julius Springer Prize for Applied Physics and Materials Research Society Mid-Career Award. He has been elected to the American Academy of Arts and Sciences, AAAS and National Academy of Sciences.
  
  The Dai Laboratory has advanced the synthesis and basic understanding of carbon nanomaterials and applications in nanoelectronics, nanomedicine, energy storage and electrocatalysis.
  
  Nanomaterials
  The Dai Lab pioneered some of the now-widespread uses of chemical vapor deposition for carbon nanotube (CNT) growth, including vertically aligned nanotubes and patterned growth of single-walled CNTs on wafer substrates, facilitating fundamental studies of their intrinsic properties. The group developed the synthesis of graphene nanoribbons, and of nanocrystals and nanoparticles on CNTs and graphene with controlled degrees of oxidation, producing a class of strongly coupled hybrid materials with advanced properties for electrochemistry, electrocatalysis and photocatalysis. The lab’s synthesis of a novel plasmonic gold film has enhanced near-infrared fluorescence up to 100-fold, enabling ultra-sensitive assays of disease biomarkers.
  
  Nanoscale Physics and Electronics
  High quality nanotubes from his group’s synthesis are widely used to investigate the electrical, mechanical, optical, electro-mechanical and thermal properties of quasi-one-dimensional systems. Lab members have studied ballistic electron transport in nanotubes and demonstrated nanotube-based nanosensors, Pd ohmic contacts and ballistic field effect transistors with integrated high-kappa dielectrics.
  
  Nanomedicine and NIR-II Imaging
  Advancing biological research with CNTs and nano-graphene, group members have developed π–π stacking non-covalent functionalization chemistry, molecular cellular delivery (drugs, proteins and siRNA), in vivo anti-cancer drug delivery and in vivo photothermal ablation of cancer. Using nanotubes as novel contrast agents, lab collaborations have developed in vitro and in vivo Raman, photoacoustic and fluorescence imaging. Lab members have exploited the physics of reduced light scattering in the near-infrared-II (1000-1700nm) window and pioneered NIR-II fluorescence imaging to increase tissue penetration depth in vivo. Video-rate NIR-II imaging can measure blood flow in single vessels in real time. The lab has developed novel NIR-II fluorescence agents, including CNTs, quantum dots, conjugated polymers and small organic dyes with promise for clinical translation.
  
  Electrocatalysis and Batteries
  The Dai group’s nanocarbon–inorganic particle hybrid materials have opened new directions in energy research. Advances include electrocatalysts for oxygen reduction and water splitting catalysts including NiFe layered-double-hydroxide for oxygen evolution. Recently, the group also demonstrated an aluminum ion battery with graphite cathodes and ionic liquid electrolytes, a substantial breakthrough in battery science.

  Current Research and Scholarly Interests As a physician-scientist involved in the care of patients and investigating novel pediatric molecular imaging technologies, my goal is to develop innovative, safe, accurate and efficient imaging solutions to significant problems in disease diagnosis. My research team works on novel cellular imaging techniques for improved detection and characterization of malignant tumors in pediatric patients, for the diagnosis of immune system disorders and for in vivo evaluation of stem cell transplants.
