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.

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.
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.
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.

Bio Dr. Demirci is currently an associate professor at Stanford University School of Medicine, Canary Center Early Cancer Detection. Prior to his Stanford appointment, he was an Associate Professor of Medicine at Brigham and Women's Hospital, Harvard Medical School and at Harvard-MIT Division of Health Sciences and Technology serving at the Division of Biomedical Engineering, Division of Infectious Diseases and Renal Division. He leads a group of 20+ researchers focusing on micro- and nano-scale technologies. He received his B.S. degree in Electrical Engineering in 1999 as a James B. Angell Scholar (summa cum laude) from University of Michigan, Ann Arbor. He received his M.S. degree in 2001 in Electrical Engineering, M.S. degree in Management Science and Engineering in 2005 and Ph.D. in Electrical Engineering in 2005, all from Stanford University.
The Demirci Bio-Acoustic MEMS in Medicine Labs (BAMM) laboratory specializes in applying micro- and nanoscale technologies to problems in medicine at the interface between micro/nanoscale engineering and medicine. We apply innovative technologies to clinical problems. Our major research theme focuses on creating new microfluidic technology platforms targeting broad applications in medicine. In this interdisciplinary space at the convergence of engineering, biology and materials science, our goal is to create novel technologies for disposable point-of-care (POC) diagnostics and monitoring of infectious diseases, cancer and controlling cellular microenvironment in nanoliter droplets for biopreservation and microscale tissue engineering applications. These applications are unified around our expertise to test the limits of cell manipulation by establishing microfluidic platforms to provide solutions to real world problems at the clinic.
Our lab creates technologies to manipulate cells in nanoliter volumes to enable solutions for real world problems in medicine including applications in infectious disease diagnostics and monitoring for global health, cancer early detection, cell encapsulation in nanoliter droplets for cryobiology, and bottom-up tissue engineering. His research interests involve applications of microfluidics and acoustics in medicine, especially: microfluidics for inexpensive, disposable CD4 counts and viral load for HIV in resource-constrained settings for global health problems; 3-D bioprinting and tissue models including 3-D cancer and neural cultures. Dr. Demirci has published over 80 peer reviewed publications in journals including PNAS, Nature Materials, Nature Communications, Advanced Materials, Small, Trends in Biotechnology, Chemical Society Reviews and Lab-chip, over 150 conference abstracts and proceedings, 10+ book chapters, and an edited book. His work was highlighted in Wired Magazine, Nature Photonics, Nature Medicine, MIT Technology Review, Reuters Health News, Science Daily, AIP News, BioTechniques, and Biophotonics. His scientific work has been recognized by numerous national and international awards including the NSF Faculty Early Career Development (CAREER) Award (2012), and the IEEE-EMBS Early Career Achievement Award (2012). He was selected as one of the world’s top 35 young innovators under the age of 35 (TR-35) by the MIT Technology Review. In 2004, he led a team that won the Stanford University Entrepreneur’s Challenge Competition and Global Start-up Competition in Singapore. His work has been translated to start-up companies including DxNow Inc. and KOEK Biotechnology.
