        Dr Jensen (Author photo 1, Author photo 2, Author photo 3, Author photo 4, Author photo 5, Author photo 6, Author photo 7, Author photo 8, Author photo 9, Author photo 10, Author photo 11, Author photo 12; Video 1, available online at www.VideoGIE.org) earned his medical degree at the University of Washington Medical School in Seattle. He completed a medical internship and first-year medical residency at University of Oregon and Affiliated Hospitals. He served as a Major in the U.S. Army Medical Corps and was Director of a Preventive Medicine Department. Then he completed a second-year medical residency at Wadsworth Veterans Administration (VA) Hospital in Los Angeles and a fellowship in gastroenterology through a joint program at UCLA and Wadsworth VA Hospitals. He has been on the faculty at these institutions and a member of the Center for Ulcer Research and Education Digestive Diseases Research Center (CURE: DDRC) since completion of his GI fellowship training.

        Dr Jensen is a Professor of Medicine (in-residence academic series) at the David Geffen School of Medicine at the University of California, Los Angeles (UCLA). He is also Associate Director of the CURE: DDRCC where he directs the Human Studies Core. He is a key investigator and on the executive committee of CURE. He is a staff physician in the UCLA Vatche and Tamar Manoukian Division of Digestive Diseases (UCLA DDD). He is also a staff physician in the GI Section of the VA Greater Los Angeles Healthcare Center. He is a member of the UCLA DDD Research Council. He directs the CURE Hemostasis Research Group. He and the Research Group have performed clinical outcomes research, teaching, and patient care at UCLA and West LA VA Hospitals for more than 3-1/2 decades.
        Dr Jensen’s research interests include multicenter, prospective, and randomized controlled trials in diagnosis and endoscopic hemostasis of GI hemorrhage; primary and secondary prevention of GI bleeding; GI outcomes and health service studies; and technology-assessment research related to endoscopy and GI bleeding. He has been the principal investigator (PI) or a coinvestigator on many multicenter controlled trials including both national and international studies. He has been continuously funded by investigator-initiated, peer-reviewed federal grants since he first joined the UCLA faculty. He has been the PI or a coinvestigator on multiple studies jointly funded by the National Institutes of Health (NIH) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Also, he has received other research funding from the VA, Department of Defense, American Society for Gastrointestinal Endoscopy (ASGE), American College of Gastroenterology (ACG), and industry. He has been a member of different study sections including the VA Merit Review Board and the NIH Reviewers Reserve for special study sections; reviewer of NIH K23 and K24 awards; and has been a member of site visits to centers proposing research in gastrointestinal endoscopy, randomized controlled trials, GI technology, and clinical and outcomes research studies.
        Dr Jensen has 5 sources of research funding for ongoing and new studies. Last year, he received a new 5-year grant from the Veterans Administration (VA) Research Service (Merit Review clinical grant) for a randomized controlled trial (RCT) of Doppler endoscopic probe for blood flow monitoring to prevent delayed postpolypectomy-induced bleeding. This is a multicenter RCT involving VA West Los Angeles and UCLA. Soon it was expanded to include a Los Angeles Kaiser Permanente Hospital and later University of Nevada, Las Vegas. Before that, he and his CURE GI Hemostasis Research Group completed another 5-year VA Merit Review grant and reported results of 2 RCTs of blood-flow monitoring to improve endoscopic hemostasis and to reduce rebleeding rates of patients with severe upper-GI (UGI) hemorrhage from nonvariceal lesions or from varices and focal lesions related to portal hypertension. Another study is being supported by an ASGE Research Foundation grant and also by the CURE: DDRCC. It is an RCT of severe nonvariceal UGI hemorrhage comparing large over-the-endoscope hemoclipping (OTSC) with standard endoscopic hemostasis. He also has research funding through the CURE: DDRC Center grant and directs the Human Studies Core, which also supports research services for multiple other CURE investigator’s clinical and outcomes studies. He also is the principal investigator of an NIH GI T32 training grant that funds research trainees who aspire to be the next generation of investigators in digestive diseases. A new research grant from Medtronic is for an investigator-initiated study at UCLA and WLA VA, which will evaluate the role of urgent colon capsule endoscopy for lesion localization and diagnosis of patients with severe hematochezia.
        Dr Jensen has published more than 279 peer-reviewed papers, case reports, chapters, books, editorial reviews, and other reports, and has also published 308 abstracts. He has been on several editorial boards and is a regular reviewer for such peer-reviewed journals as the New England Journal of Medicine, Annals of Internal Medicine, JAMA, Gastroenterology, American Journal of Gastroenterology, Gastrointestinal Endoscopy, and Endoscopy. He has been an invited faculty member of numerous postgraduate GI courses and consensus conferences on endoscopy and GI bleeding including local, regional, national, and international symposia.
        Dr Jensen has successfully mentored many young clinical, outcomes, and endoscopy investigators for research and career development for over 35 years. Many of his trainees are full-time faculty or clinical faculty of academic medical centers in the United States or abroad. He is the PI and director of an NIH T32 training grant for gastroenterology at CURE, UCLA, and the VA and previously had funding of an NIH K24 grant for mentoring and clinical research. He has received both local and national awards as a distinguished lecturer, distinguished mentor, educator, and clinical researcher. Dr Jensen has served on numerous committees of the ASGE and is a past councilor of the ASGE. He also served as a member of the ACG Research Committee. In May 2012, Dr Jensen was awarded the Rudolf V. Schindler award, the highest award of the ASGE.
