Pilleriin Sikka
Postdoctoral Scholar, Anesthesiology, Perioperative and Pain Medicine
Basic Life Research Scientist, Multispecialty AnesthesiologyCurrent Research and Scholarly InterestsWhat makes certain experiences transformative, and how can we harness them to support resilience and mental health? I explore this question by studying emotions across various states of consciousness—waking, dreaming, anesthesia, psychedelics, and meditation. With a background in psychology, neuroscience, and anesthesiology, I bring together methods that are rarely combined: daily diaries and surveys, language and narrative analysis, neurophysiological recordings, lab experiments, and clinical trials. My work has three main aims: (1) to understand how affective experiences unfold across states; (2) to test whether these experiences can be deliberately shaped to support mental health; and (3) to identify the mechanisms that make them transformative. This interdisciplinary approach has led to the first controlled studies of anesthesia-induced dreams for trauma, new insights into peace of mind and emotion regulation, and cross-state comparisons showing how affective experiences in altered states can foster resilience. My long-term goal is to develop a new frontier in affective science: the study of how transformative experiences across different states of mind can improve well-being.

Julia Fridman Simard
Associate Professor of Epidemiology and Population Health, of Medicine (Immunology & Rheumatology) and, by courtesy, of Obstetrics and Gynecology (Maternal Fetal Medicine)
BioJulia Fridman Simard, ScD, is an Associate Professor of Epidemiology & Population Health, and of Medicine in Immunology and Rheumatology and Obstetrics and, by courtesy, Gynecology in Maternal Fetal Medicine at Stanford University School of Medicine.
Dr. Simard earned her Masters and Doctorate of Science in Epidemiology degrees at the Harvard School of Public Health. During that time she trained with investigators at the Section of Clinical Sciences, Division of Rheumatology, Immunology, and Allergy at Brigham and Women’s Hospital and the Cardiovascular Epidemiology Research Unit at Beth Israel Deaconess Medical Center. In 2008, Dr. Simard relocated to Sweden to begin a Postdoctoral Fellowship in Clinical Epidemiology at the Karolinska Institute in Stockholm. She became an Assistant Professor in their Clinical Epidemiology Unit in 2011, and was later honored with a Karolinska Institute Teaching Award. Leveraging the population-based registers of Sweden, Dr. Simard initiated a national register linkage study to examine the utility of registers in Systemic Lupus Erythematosus (SLE) research and develop an extensive data repository for future epidemiologic investigations.
While maintaining a close collaboration with the Karolinska Institute, she joined Stanford’s faculty in 2013. Dr. Simard's work includes outcomes such as malignancy, stroke, infection, and mortality, in patients with systemic autoimmune rheumatic diseases with a focus on systemic lupus erythematosus. She has made significant contributions at the intersection of reproductive epidemiology and rheumatic disease fueled initially by a K01 career development award from the NIH (NIAMS) to study maternal and fetal outcomes in systemic lupus pregnancy. This led to collaborations with colleagues at Stanford, throughout the US, and abroad, and a series of projects focused on the diagnosis of preeclampsia and associated risks in pregnant women with systemic lupus. With support from the Preeclampsia Foundation for her lab's work examining preeclampsia risk in high-risk populations, and a McCormick Faculty Award from Stanford Medicine, Dr. Simard is taking important steps towards understanding this significant pregnancy complication in pregnancies complicated by rheumatologic disease. Dr. Simard is leading an international study of hydroxychloroquine in lupus pregnancy leveraging mixed methods in partnership with qualitative researchers, patients, clinicians, and epidemiologists in Sweden, Canada, and in the United States, and is expanding to other medications and rheumatic autoimmune diagnoses.
Additionally, Dr. Simard's lab is also interested in how misclassification, missed opportunities, and misdiagnosis contribute to disparities in complex conditions. In addition to methodologic issues around misclassification and bias and the largely clinical epidemiology focus of her work, Dr. Simard's work examines social determinants of health and health disparities. With support from an R01 from NIH (NIAID), her lab is also studying the role of cognitive errors in clinical decision making for female-predominant diseases. This work evaluates this bias in multiple clinical specialties, including rheumatology, neurology, and primary care, and uses mixed methods including randomized survey-based studies and qualitative interviews. -

Shruti Singh Kakan
Postdoctoral Scholar, Ophthalmology
BioI am a Biomedical Scientist with a Ph.D. in Translational Sciences. During my PhD, I investigated how the tear composition of patients with Sjogren’s Disease (SjD) associated Dry Eye disease, differed molecularly from patients with other forms of dry eye disease or other autoimmune diseases. These differences can be leveraged to develop a diagnostic test, and we established this proof-of concept using tear microRNA that could differentiate SjD-Dry Eye from Dry Eye associated with Meibomium Gland Disease.
During my postdoctoral training at Stanford, I am advancing my genomics data analysis skillset to include DNA methylation, chromatin states and accessibility, and long range DNA interactions through Whole Genome Bisulfite Sequencing, Chromatin Immunoprecipitation followed by sequencing (ChIP-Seq), ATAC-Sequencing and HiC, respectively. I am applying these techniques to study mechanisms of retinal homeostasis during development, aging and retinal disease, including both inherited and metabolic retinal diseases that cause blindness. -

Sidhartha Sinha
Assistant Professor of Medicine (Gastroenterology and Hepatology)
Current Research and Scholarly InterestsThere are two primary and overlapping emphases of my research, both of which are driven and united by needs-based innovation and translational potential:
(1) Understanding the microenvironment of the inflamed versus normal gut in order to identify better therapeutic targets for people with immune-¬mediated GI disorders. Here, our investigations include understanding the influence and interactions of pharmacologic and dietary interventions on gut microbiome/metabolomic changes and the host immune response. In the context of providing patients with new understanding and solutions for their disease, I have led and advised on the design of both pilot and large clinical trials (including new FDA approved therapies) for anti-inflammatory therapies;
(2) Applying novel approaches and technologies (including natural language processing, computer vision, and reinforcement learning) to identify and address unmet clinical needs. In this area we have ongoing and published efforts in my lab to validate and develop solutions to pressing clinical needs. We have developed/led new drug delivery technologies with a multidisciplinary team that have shown strong potential in ongoing human IBD clinical trials. My lab has utilized both supervised and unsupervised approaches to analyze social media discourse and unstructured data sets for identifying patient needs that are rarely addressed in clinical settings. We have gained insights into patient perceptions around preventative health interventions, such as health screening and diet, including the dearth of evidence-based dietary recommendations to treat IBD (despite strong patient desire for solutions in this domain). -
