Hongjie Dai
The J.G. Jackson and C.J. Wood Professor of Chemistry, Emeritus
BioProfessor 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. (B.S. 1989) and applied sciences at Columbia U. (M.S. 1991). He obtained his Ph.D. from Harvard U and performed postdoctoral research with Dr. Richard Smalley. 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, National Academy of Sciences (NAS), National Academy of Medicine (NAM) and Foreign Member of Chinese 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. -

Francesco Nandkumar Dandekar
Clinical Associate Professor, Psychiatry and Behavioral Sciences
BioDr. Dandekar is a Clinical Associate Professor and Associate Director of Sports Psychiatry at Stanford University. After graduating summa cum laude from the University of Southern California with a B.S. in Biomedical Engineering, he earned a Regents Scholarship to complete his M.D. at UC San Diego, where he received the American Academy of Neurology’s Prize for Excellence. During his residency and fellowship at Stanford, Dr. Dandekar provided care to a variety of patients utilizing a combination of medication management, psychotherapy, and lifestyle changes (sleep, nutrition, exercise, recovery). Teamed with Clinical Professor Dr. Douglas Noordsy, he helped to incorporate psychiatric services into Stanford's sports psychology program, and continues to see elite athletes as part of the Stanford Sports Psychiatry Clinic. He also specializes in treating physicians, and sees many residents, fellows, and attendings in his private practice. In his free time, he enjoys playing tennis, chess, and guitar.

Rebecca Dang
Instructor, Pediatrics
BioDr. Rebecca Dang is an Instructor in the Division of General Pediatrics at Stanford University. She earned her medical degree at Georgetown School of Medicine and completed her pediatric residency at Kaiser Permanente Northern California. She also completed pediatric hospital medicine fellowship and a master’s program in clinical research and epidemiology at Stanford University. Dr. Dang provides clinical care for children on the pediatric ward and newborn nursery.
Dr. Dang’s research interest focuses on high-value pediatric care, which she hopes to improve through building evidence for common, understudied practices. Common practices that are ubiquitous throughout pediatric medicine are temperature measurement and management. Despite temperature measurement and the subsequent detection of ‘normal’ or ‘abnormal’ values driving clinical decision making, these temperature thresholds may be outdated or poorly defined. Dr. Dang has led many projects on temperature-related topics, including routine temperature measurement at well-child visits, pediatric temperature percentiles, risk factors for and outcomes of neonatal hypothermia in the newborn nursery, and newborn temperature norms. This work has led to first-author publications in the high-impact journals of Academic Pediatrics, Pediatrics, Journal of Pediatrics, JAMA Network Open, and Hospital Pediatrics. She has secured continual institutional and foundation funding, including a Maternal & Child Health Research Institute clinical trainee award and master’s tuition program, Gerber Foundation main and novice research award, the Department of Pediatrics’ Bridge-to-K Program, and the PEDSnet Scholars Program. -
