Yusuke Nakauchi
Postdoctoral Research Fellow, Stanford Cancer Center
Current Research and Scholarly Interests From 2005 to 2010, my work as a clinical hematology fellow allowed me to experience first-hand how scientific advances that started in a laboratory can transform the lives of patients. While many of my patients were cured of their disease with allogeneic hematopoietic stem cell transplantation, underscoring the importance of anti-tumor immunotherapy in eradicating leukemia, I witnessed face-to-face their suffering from the long-term consequence of graft-versus-host disease (GVHD). This experience was ultimately what drove me to engage in research to discover novel therapies. For this reason, I embarked on a PhD program in 2010 to design antibody therapy to (i) target GVHD and (ii) target hematological malignancies. Under the mentorship of Professor Hiromitsu Nakauchi at the University of Tokyo, an international leader in hematopoiesis, I developed allele-specific anti-human leukocyte antigen (HLA) monoclonal antibodies for severe GVHD caused by HLA-mismatched hematopoietic stem cell transplantation (Nakauchi et al., Exp Hematol, 2015). This study was the first to find that anti-HLA antibodies can be used therapeutically against GVHD. That success gave me the motivation and confidence to further my research beyond targeting GVHD, to targeting leukemic stem cells through my current postdoctoral fellowship in the laboratory of Professor Ravindra Majeti, Department of Hematology at Stanford University.
Many people suffer from leukemia each year, but we still don?t know how to completely cure it. Recent advances in sequencing technologies have tremendously improved our understanding of the underlying mutations that drive hematologic malignancies, although, the reality is that the majority of the mutations are not easily ?druggable? and the discovery of these mutations has not yet made a significant impact in patient outcomes. I view this perhaps the most crucial challenges facing a translational cancer researcher like myself. My current research is a major step toward my long term goal to make personalized medicine a reality for patients with acute myeloid leukemia (AML) and other hematologic malignancies. Although my research is focused on targeting Ten-Eleven Translocation methylcytosine dioxygenase-2 (TET2) mutations, I anticipate it will lead to a better understanding of the cell context requirement for TET2 mutations in AML and help identify the critical cells to target to both prevent the development of de novo leukemia and halt relapse. It may also prove of value to understanding of the biology of a range of other cancers. -
Karina Nakayama
Instructor, Cardiothoracic Surgery
Bio I am an Instructor in the Department of Cardiothoracic Surgery and the Cardiovascular Institute at Stanford University working with Dr. Ngan Huang using spatially patterned biomimetic niches to direct cell fate, angiogenesis, and tissue regeneration. Prior to Stanford, I attained a PhD from the University of California, Davis in Biomedical Engineering in the translational laboratory of Dr. Alice Tarantal working towards regenerative therapies for congenital kidney diseases using decellularized kidney matrices and directed differentiation of stem and progenitor cells towards renal lineages.
I am dedicated to understanding the biomechanical cell-substrate interactions that modulate cell phenotype and behavior towards enhancing tissue neurovascularization, regeneration, and function. The overarching goal of my research is the development of bioengineered therapeutics that can lead to future regenerative therapies, with relevance to cardiovascular and musculoskeletal injuries and diseases. My work to date, suggests that the composition, spatial organization, and mechanical properties of extracellular matrix microenvironments play a directive role in modulating cell phenotype and function. The scientific themes that frame my research program are the elucidation of novel biomechanical pathways that can be harnessed to enhance engineered vasculature, innervation, and function of cardiac and skeletal muscle, and complex multi-tissue composites using methods that range from nanopatterning of biomaterials and RNASeq, to modular immuno-physiologic culture systems and regenerative rehabilitation.
My research background spans the fields of biomedical engineering, developmental and stem cell biology, and cardiovascular medicine, making multi-disciplinary research at the interface of these disciplines natural and primed for innovation. I have enjoyed research funding through the California Institute of Regenerative Medicine (CIRM), the NIH/NHLBI (T32 and F32 fellowships), and the American Heart Association. I recently received K99/R00 funding through the NIH/NHLBI and look forward to using this award to jumpstart my independent research career.
I am eager to mentor undergraduates, graduate students, and postdocs from diverse backgrounds into critically thinking ambassadors of science, engineering, and medicine. I am excited to share my knowledge and passion for science and engineering with this next generation of talented young innovators and to be a positive force in promoting equity in education and diversity in STEM fields. -

Margaret Jane Neff
Clinical Associate Professor (Affiliated) [Vapahcs], Medicine - Med/Pulmonary and Critical Care Medicine
Bio My training is in Pulmonary & Critical Care Medicine, and I've been blessed to be part of the care of many patients and their families. My clinical research interests have been in the field of critical care medicine and ARDS, a type of acute respiratory failure seen commonly in patients with severe injuries or illnesses. I also have a particular interest in evaluating and improving processes for care. Issues like standardizing processes to improve reliability, improving safety of handoffs, and exploring ways to teach "roundsmanship" (the process of discussing patients' care with a group of providers) are current interests of mine.
The future of medical care depends on training the next generation of providers, and I'm thankful to be part of training this next generation. Teaching at the bedside or in formal classroom settings gives me great joy and satisfaction. I'm delighted to work with a great, multidisciplinary team of physicians, nurse practitioners, nurses, respiratory therapists, and pharmacists. I add to that team our patients and families, for it truly takes a team to provide care that is both excellent and compassionate. -
