Ian H. Gotlib
Marjorie Mhoon Fair Professor, Psychology
Stanford University
Bio
In his research, Dr. Gotlib examines psychobiological factors that place individuals at increased risk for developing depression and engaging in suicidal behaviors, as well as processes that are protective in this context. More specifically, Dr. Gotlib examines neural, cognitive, social, endocrinological, and genetic factors in depressed individuals and applies findings from these investigations to the study of predictors of depression in children at risk for this disorder. In related projects, Dr. Gotlib is also examining the differential effects of early life stress on the trajectories of neurodevelopment in boys and girls through puberty in an effort to explain the increased prevalence of depression and suicidal behaviors in girls in adolescence. Finally, Dr. Gotlib is extending this work to the study of brain function and structure, endocrine function, and behaviors in neonates and infants being raised in suboptimal environments.
Dr. Gotlib’s research is supported largely by grants from the National Institutes of Health. He has also been funded by the National Health Research Development Program and the Medical Research Council of Canada, and leads an interdisciplinary team funded by PHIND. Dr. Gotlib has received the Distinguished Investigator Award from the National Alliance for Research in Schizophrenia and Affective Disorders, the Joseph Zubin Award for lifetime research contributions to the understanding of psychopathology, the APA Award for Distinguished Scientific Contribution, the APS Distinguished Scientist Award, and a MERIT award from NIMH. He has published over 500 scientific articles and has written or edited several books in the areas of depression and stress, including the Handbook of Depression with Constance Hammen, now in its 3rd edition. He is a Fellow of the American Psychological Association, the Association for Psychological Science, and the American Psychopathological Association, and is Past President of the Society for Research in Psychopathology.

Karl Deisseroth
D. H. Chen Professor, Professor of Bioengineering and of Psychiatry and Behavioral Sciences
Stanford University
Bio
Karl Deisseroth is Professor of Bioengineering, and of Psychiatry and Behavioral Sciences, at Stanford, and Investigator of the Howard Hughes Medical Institute. Deisseroth received his undergraduate degree from Harvard in 1992, his PhD from Stanford in 1998, and his MD from Stanford in 2000. Deisseroth then completed his medical internship and adult psychiatry residency at Stanford, and is board-certified by the American Board of Psychiatry and Neurology. He continues as a practicing psychiatrist (inpatient and outpatient) at Stanford with specialization in affective disorders and autism-spectrum disease, employing medications along with neural stimulation. Deisseroth also serves as Director of Undergraduate Education for Bioengineering at Stanford, and is known for providing free educational programs that have disseminated his technologies to thousands of laboratories around the world.
In exploring how properties of the brain arise from activity of its cellular components, Deisseroth has pioneered the basic science discoveries that enabled this goal, including resolving the structural and functional mysteries of natural light-gated ion channels, and discovery of the neural cell types and connections that cause adaptive and maladaptive behavior. Along the way, over the last 17 years, his laboratory has created and developed technologies for observing and controlling biological systems (like the brain) at high resolution, while maintaining these systems in the intact state; these technologies include optogenetics, hydrogel-tissue chemistry, and a broad range of enabling methods.
Deisseroth has also published a book of literary nonfiction, relating the experiences of psychiatric patients to modern neuroscience– Projections (Penguin Random House)– in 2021.
Deisseroth was elected to the US National Academy of Medicine in 2010, to the US National Academy of Sciences in 2012, and to the US National Academy of Engineering in 2019. For his work, Deisseroth has received the 2010 Nakasone Prize, 2012 Perl Prize, 2013 Lounsbery Prize, 2013 Gabbay Prize, 2013 BRAIN Prize, 2014 Dickson Prize in Science, 2015 Breakthrough Prize, Keio Prize, 2015 Lurie Prize, 2015 Albany Prize, 2015 Dickson Prize in Medicine, 2016 BBVA Award, 2017 Massry Prize, 2017 Fresenius Prize, 2018 Gairdner Award, 2018 Kyoto Prize, 2020 Heineken Prize, and 2021 Lasker Award.
Abstract
In this fireside chat, we will explore with Prof. Deisseroth fascinating insights from his book…
- How optogenetics is mapping pathways of emotion in the brain
- Differences in neural processing for autism, anxiety, and bipolar disorder
- How genetics and evolution played a role in allowing mental disorders to exist

Tony Faranesh
Staff Research Scientist
Google
Bio
Tony is a research scientist with a focus on using consumer technologies to empower people to manage and improve their health. At Fitbit and Google, Tony leads algorithm development and clinical studies using wearables for disease screening and monitoring. Tony led the Fitbit Heart Study, the clinical trial for the Fitbit Irregular Rhythm Notifications feature, designed to detect signs of atrial fibrillation from the optical heart rate sensors on Fitbit devices.
Tony obtained his Ph.D. in Biomedical Engineering from Johns Hopkins University and did a post doctoral fellowship at Stanford University in the department of Radiology. He has spent much of his career in cardiovascular MRI research. Before joining Fitbit, Tony was a research scientist at the National Heart, Lung, and Blood Institute, part of the National Institutes of Health, in Bethesda, Maryland.
Background: Morbidity from undiagnosed atrial fibrillation (AF) may be preventable with early detection. Many consumer wearables contain optical photoplethysmography (PPG) sensors to measure pulse rate. PPG-based software algorithms that detect irregular heart rhythms may identify undiagnosed AF in large populations using wearables, but minimizing false positive detections is essential.
Methods: We performed a prospective remote clinical trial to examine a novel PPG-based algorithm for detecting undiagnosed AF from a range of wrist-worn devices. Adults aged ≥ 22 years in the United States without AF, using compatible wearable Fitbit devices and Android or iOS smartphones, were included. PPG data were analyzed using a novel algorithm that examines overlapping 5-minute pulse windows (tachograms). Eligible participants with an irregular heart rhythm detection (IHRD), defined as 11 consecutive irregular tachograms, were invited to schedule a telehealth visit and were mailed a one-week ambulatory electrocardiogram (ECG) patch monitor. The primary outcome was the positive predictive value (PPV) of the first IHRD during ECG patch monitoring for concurrent AF.
Results: 455,699 participants enrolled (median age 47 years, 71% female, 73% White) between May 6 and October 1, 2020. IHRDs occurred for 4,728 (1%) participants, and 2,070 (4%) aged ≥ 65 years during a median of 122 (IQR, 110–134) days at risk for an IHRD. Among 1,057 participants with an IHRD notification and subsequent analyzable ECG patch monitor, AF was present in 340 (32.2%). Of the 225 participants with another IHRD during ECG patch monitoring, 221 had concurrent AF on the ECG and 4 did not, resulting in an IHRD PPV of 98.2% (95% confidence interval [CI], 95.5%–99.5%). For participants aged ≥ 65 years, the IHRD PPV was 97.0% (95% CI, 91.4%–99.4%).
Conclusions: A novel PPG software algorithm for wearable Fitbit devices exhibited a high PPV for concurrent AF and identified participants likely to have AF on subsequent ECG patch monitoring. Wearable devices may facilitate identifying individuals with undiagnosed AF.
