Siddhartha Jaiswal
Associate Professor of Pathology
Current Research and Scholarly InterestsWe identified a common disorder of aging called clonal hematopoiesis of indeterminate potential (CHIP). CHIP occurs due to certain somatic mutations in blood stem cells and represents a precursor state for blood cancer, but is also associated with increased risk of cardiovascular disease and death. We hope to understand more about the biology and clinical implications of CHIP using human and model system studies.

Clinical Associate Professor, Medicine
BioDr. M. Nicole Jamali focus has been in leadership, scientific innovation and streamlining business ventures. Over the past 20 years since graduation from Stanford Internal Medicine Residency, she has held National Positions in AMA as Western Caucus Chair and Appointee to Joint Commission Board. She was reelected to Board of Joint Commission three terms for total of 9 years. She helped rewrite multiple TJC Standards including creation of the Stroke Center of excellence standards and annual "new ideas section of the board". At AMA she authored and passed multiple House rules on variety of subjects affecting thousands of providers and healthcare centers. Her experiences in private practice, group practice, Hospitalist, Insurance Directorship lead to multiple innovative projects including first e-prescription covering both meds and DME in 1999 titled eRemedy,. She then created the first wrong site surgery device which was patented. This project lead to creation of first Transplant App called TPOD which was then simplified to TAPP. It was beta tested in USC and perfected in UCSF Transplant.
Her work with various Insurance companies resulted in streamlined programs and teaching modules improving patient access to health care and millions of dollars in hospital savings of unnecessary admissions.
Her work in creation and streamlining and connecting with local Primary Care providers resulted in rapid expansion of the Hospitalist program of local Hospital by 300%

Jlateh Vincent Jappah
Ph.D. Student in Health Policy, admitted Autumn 2021
Master of Arts Student in Economics, admitted Spring 2024BioJlateh Vincent Jappah is a PhD Candidate in Health Policy (Health Economics) at Stanford. His research interests intersect between methods that enhance access to the social determinants of health and the provision of appropriate and timely healthcare services, with the aim of reducing avoidable morbidity and mortality and improving overall health and well-being, especially for underserved and vulnerable populations.
Jappah contends that although health insurance and access to healthcare services are important elements in the health production function, other structural and socio-economic factors collude to either foster or erode health. As such, he has a keen interest in public policy, economics, medicine, global public health, maternal and child health, and a curiosity to understand those socio-political and institutional forces that shape health and well-being. He is also interested in machine learning and artificial intelligence in healthcare.
In addition to the United States, Jappah has lived and worked in several countries in Africa, Asia, and Europe.
He is bi-lingual (English and Russian). -

Daniel Jarosz
Senior Associate Dean, Basic Science, Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly InterestsMy laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.
