Joshua Biddle, MD

Josh Biddle is a junior resident in the global health track of the Stanford University internal medicine program. He earned his   More  M.D from the University of California, San Francisco and did his undergraduate work at UC Berkeley and the City College of San Francisco.

Josh first started working with underserved populations as a student at the City College of San Francisco when he volunteered in the emergency department at San Francisco General Hospital. From there he began volunteering as a medical assistant at the Glide Memorial Church Health Clinic
in San Francisco’s Tenderloin District. Once at UC Berkeley he became a GED tutor at San Quentin State Prison. Around this time he also went to Nairobi, Kenya to volunteer at a clinic and learning center in one of the city’s poorest urban slums.

After graduating from UC Berkeley, he again spent a summer volunteering at a rural hospital in western Kenya. Between his first and second year of medical school he returned to Kenya to work on a project that investigated the effects of integrating family planning and HIV services in rural health clinics. After his third year of medical school, he was awarded a 9-month Fulbright Scholarship and returned to Kenya for a fourth time to help coordinate an NIH-funded case-control study of Burkitt’s Lymphoma around Lake Victoria. Finally, before beginning his internal medicine residency at Stanford, he spent two months in the country of Georgia on a CDC-Hubert Global Health Fellowship coordinating a project to evaluate the Ministry of Health’s hepatitis C testing and treatment program in the penitentiary system.

Josh choose the Global Health Track at Stanford because of the it’s flexibility, mentorship support, protected research time, funded travel, and the vast array of interdisciplinary opportunities across the wider Stanford campus. His research interests include global oncology and hepatitis. He is also interested in learning more about health policy and economics and developing the necessary tools to understand and ultimately implement large scale, public health initiatives in the developing world.

Nicholas Degner, MD, MPH

Nicholas Degner was first inspired to go into medicine and global health while performing graduate laboratory research on  More HIV pathogenesis and prevention at the Aaron Diamond AIDS Research Center at Rockefeller University in New York City. The following year he enrolled in medical school at the University of California, San Diego. At UCSD, Nicholas had the opportunity to spend a summer in Mozambique conducting research aiding in the development of an easy-to-use, low cost, field-portable device for the simultaneous diagnosis of HIV and its numerous co-infections. With the ability to integrate and apply both basic science and epidemiology to clinical challenges, Nicholas was inspired by this translational approach to global health.

Seeking to improve his skills in epidemiology and biostatistics, Nicholas pursued an MPH at the Johns Hopkins Bloomberg School of Public Health. At Johns Hopkins he had the opportunity to continue his interest in translational research, particularly novel diagnostic tests, conducting laboratory research with the Center for Tuberculosis Research evaluating microRNAs as potential biomarkers of tuberculosis infection and treatment response. He also had the opportunity to conduct field research in rural Zambia to assess the potential of incorporating environmental factors into malaria case detection methods.

Nicholas also has an interest in human rights. At UCSD, he worked with the San Diego County Jail system to conduct a study evaluating methods to screen newly admitted prisoners for tuberculosis. At Johns Hopkins, he worked with the Center for Public Health and Human Rights to put out a report on human rights abuses, particularly barrel bomb attacks, carried out against medical personnel during the Syrian Civil War.

His experience in global health has been at both the community and international levels. As an undergraduate, he volunteered as a social services worker for underserved patients in New Haven, CT. In medical school, he coordinated the Hepatitis B program at Pacific Free Clinic, a student-run initiative vaccinating and monitoring uninsured HBV-positive or at-risk populations in San Jose. Overseas, Andy interned with Nyaya Health, assisting the organization in collaborating with Nepal’s national Ministry of Health to establish a hospital in rural Achham. He then trained in design thinking at Stanford’s Hasso Plattner Institute of Design, where he partnered with the International Centre for Diarrhoeal Disease Research, Bangladesh to conduct on-site needs finding and user testing for a pediatric ICU device in Dhaka and Rangpur.

Andy chose to attend Stanford for his residency due to the remarkable flexibility of the global health track, along with its opportunities for mentorship in developing a research career. His current academic interests include investigating health outcomes and cost-effectiveness of cardiovascular disease in low- and middle-income countries. His other professional activities involve generating and evaluating appropriate medical technologies, in particular their role in combating non-communicable diseases in the developing world. In residency, he completed clinical rotations in Rwanda and Uganda, during which time he also conducted mixed methods research on the characteristics and motivations in women of reproductive age with rheumatic heart disease.

Mary Le Chiou, MD

Mary Le Chiou has lived in Massachusetts most of her life, exploring the western side of the state for undergrad at UMass Amherst More 

 

 

 and venturing to central MA for medical school at UMass Med. Growing up in Boston was an awesome experience filled with my large extended family, delicious home-cooked Vietnamese food, weekly fishing trips at Cape Cod in the summer, and snowball fights each winter.

After visiting Northern California during spring break of her third year of med school, however, she was hooked. She got a chance to do a sub-I at Packard in the summer and knew she could not see herself doing residency anywhere else.

As far as my career goals, she's interested in advocacy and working with the urban pediatric population to address the myriad of social issues that impact their health. She is also interested in global health and has visited Vietnam and Costa Rica to provide primary care to rural populations.
