Debra Karhson
Casual - Non-Exempt, Psychiatry and Behavioral Sciences - Child and Adolescent Psychiatry and Child Development
Bio I am interested in understanding the neural mechanisms that underlie cognitive and social functioning heterogeneity in autism spectrum disorder (ASD). Impairments in social and cognitive functioning in children with ASD are intrinsically related to the changes in information processing. Moreover, social and cognitive functioning are emergent neural processes that can be manipulated by robust molecular neuromodulators. Social behaviors are specifically related to the neuropeptides, oxytocin (OT) and arginine vasopressin (AVP), while both social and cognitive functioning have been related to the endogenous cannabinoid (or endocannabinoid) system. Therefore, my postdoctoral research (funded by a T32 postdoctoral fellowship from the NIMH) investigates the role of neuromodulators (i.e., social neuropeptides and endocannabinoids) in social functioning in autistic children. My PI-lead efforts are include mass spectrometry method development and treatment-related clinical neurophysiological assessment in autistic children. Individually, my research interests are centered on leveraging a translational neuroscience skill set to interrogate information processing in ASD pathophysiology and understand its relationship with (potential dysregulation of) endocannabinoid signaling.

Dr. Kasirajan preserves limbs, facilitates access to dialysis, and helps his patients manage conditions such as aneurysms, varicose veins, thoracic outlet syndrome, and deep vein thrombosis. Many of his limb preservation patients smoke, have diabetes, or are experiencing renal failure. Dr. Kasirajan’s experience also centers around the treatment of aneurysms and prevention of strokes.
In all cases, his goal is to provide either noninvasive or minimally invasive management whenever possible. He performs open surgery only when it is the best option. Dr. Kasirajan treats many patients with stents and stent grafts, which can shorten hospital stays and recovery times.
Dr. Kasirajan (Kasi) receives referrals of patients from primary care physicians, nephrologists, podiatrists, cardiologists, woundcare specialists, diabetologists, neurologists, and other specialists. He welcomes referrals as early as possible, ideally before patients become symptomatic. A strong proponent of doing early screening for peripheral artery disease, Dr. Kasirajan advocates for the use of the ankle-brachial index (ABI) in routine physical examinations. When providers detect an imbalance between leg and arm blood pressure, Dr. Kasirajan can help create customized strategies to address the cause before the problem worsens.
In addition to offering excellent vascular care to the community, Dr. Kasirajan joined Stanford to continue pursuing his research interests. He has conducted research into advances in minimally invasive procedures for stroke prevention and for aneurysm management. His research has also focused on how to improve surgery outcomes to help patients suffering from peripheral vascular disease. Dr. Kasirajan has been the investigator in over 40 multicenter studies involving new stent graphs, thrombectomy catheters, and other advances in endovascular technology.
Dr. Kasirajan has made more than 100 presentations worldwide on minimally invasive vascular surgery techniques and preventive care in the vascular patient.

Debra Lee Kaysen
Professor of Psychiatry and Behavioral Sciences (Public Mental Health & Population Sciences) at the Stanford University Medical Center
Current Research and Scholarly Interests Much of my current research focus is on the development of testing of accessible, scaleable, and effective treatments for trauma-related disorders and related comorbidities (e.g. substance use disorders, HIV, mood disorders). This work has focused on addressing trauma-related disorders especially in underserved populations and settings. This includes research in rural communities, with Native American communities, and with sexual minorities. My research has had a strong impact on building an evidence base on adaptations of psychotherapies for PTSD and substance use disorders for diverse populations both within and outside the United States. Our findings demonstrate that complex cognitive behavioral psychotherapies like Cognitive Processing Therapy can be culturally adapted and delivered in challenging settings (conflict settings, high poverty environments) with significant and lasting change in PTSD, depression, and functioning. This has led to work adapting CPT for diverse populations within the United States (rural Native Americans, urban Latinos) and outside of it (Iraq, DRC). Other research has focused on treatment for PTSD/SUD. My research has also found support for the use of brief telehealth interventions to build treatment engagement and to reduce drinking among trauma-exposed populations. In addition, my work has been critical in testing the feasibility of novel trauma-focused interventions for use by those with PTSD and SUD, thus paving the road for more rigorous research studies.
Current PI'ed research studies include: 1) developing and evaluating a brief motivational interviewing intervention designed to increase treatment-seeking among military personnel with untreated PTSD; a two-arm randomized comparative effectiveness trial to evaluate prevention of HIV/STI sexual risk behavior by addressing PTSD through Narrative Exposure Therapy or substance use through Motivational Interviewing among Native American men and women with PTSD; and 3) a comparison of outcomes among patients randomized to initially receive pharmacotherapy or Written Exposure Therapy delivered in primary care as well as comparing outcomes among patients randomized to treatment sequences (i.e., switching and augmenting) for patients who do not respond to the initial treatment. -

Joan Kendig
Professor of Biology in the Department of Anesthesia, Emeritus
Current Research and Scholarly Interests My laboratory tries to find out how pharmacologic agents used in the practice of anesthesia (general anesthetic and analgesic agents) lead to therapeutically desireable endpoints including unconsciousness, immobility and absence of pain. The old idea that general anesthetics are uniformly non-specific "membrane stabilizers" is giving way to a new realization that these agents exert specific actions on particular ion channels and intracellular signalling systems.
