I trained as an internist from a rural medical school in India and have been involved in teaching under- and post-graduate students in New Delhi over the last one decade. My research interests include global aging, frailty, health needs in disaster situations, medical education and ethics. I enjoy experiments with light, colors, food ingredients and words when using my camera, cooking or writing!

Sophia Tan, Secretary

I am a physician from Singapore. I have had some experience in volunteering with public health projects in Bangladesh and Cambodia, and am looking forward to working to improve health in underserved populations, especially those affected by humanitarian crises.


Danielle Toth, Treasurer

I am a graduate of Georgetown University where I studied International Health. I am Argentinean-American from Miami and I love to travel and explore new places and hope to do much more of it in the future. I am pursuing an MPH at JHU, focusing on epidemiology and biostatistics and hope to continue working in global health.

Prior to JHSPH, I worked on a maternal health initiative based in India and spent a year teaching at a secondary school in Malaysia. I hold a BA in Biology from Scripps College, where I was involved in public health research and advocacy centered around South Asian communities. As a part of JBGS, I am excited to build spaces for learning and conversation about health equity and social justice issues across the world.


Chau Ngo, Event Coordinator

I am a UC San Diego alumni and a Returned Peace Corps Volunteer from Ghana. Born in Vietnam but grew up in Southern California, I have been fortunate enough to live in other regions around the country as well as the world. I am pursuing an MPH at Hopkins with an interest in working with marginalized populations in post-crisis scenarios.


Sabrina Rahman, Career/Alumni Liaison

My name is Sabrina Rahman and I am taking on the role of Career/Alumni Liaison with my wonderful partner Jiajia.  Through this role, I hope to introduce our classmates to an array of career opportunities and the tools required to further their careers upon graduation. I am ecstatic to be a part of the JBGS family and looking forward to making amazing memories with all my classmates!

Arnold Onana, Public Affairs Coordinator

I am Arnold Onana, physician from Cameroon. I spent the last six years working in a diabetes and obesity clinic and later as a program manager in the National AIDS control program in three regions across the country of different cultures. I believe that without implementing the right policy, the usefulness of every action upstream is lost, hence my focus in Health Policy and Systems in the MPH program at the Johns Hopkins Bloomberg School of Public Health.
