The year in Malawi was both trying and amazing, and I'm incredibly glad that I was one of the fortunate people selected to experience it. Since it was my first job after residency, I was as uncertain of myself and what I could do when I began. By the time I finished, I knew that there was an awful lot that I could handle: challenges that only my colleagues from outside the USA really understand. This served me well as a Pediatric Infectious Diseases fellow, as I am much more confident in my practice and decisive in my clinical decision making. I feel I have gained a better understanding of what is important both in life and in the practice of medicine which, among other things, helps me to relate better to the families for which I care and better utilize resources in the hospital. Any description of what I gained from my time with the PAC cannot leave out the very good friends I made; it was a powerful bonding experience. Also, I must admit that I miss the sunny skies and friendly smiles of Malawi, and while not discounting the impact of practicing in the USA, my work in Malawi brought with it a sense of significance that I have not yet experienced anywhere else and which carries me through to this day."

How has working overseas changed me? It has made me more likely to try to develop collaborations overseas, and more interested in developing research projects that will be relevant to the world's poor and underserved. Working with UNICEF and other global international health organizations gave me a better sense of the scope of the problem of HIV and TB in Southern Africa, and a better understanding of how the explosion of problems (such as XDR TB) there relates to our security in the United States."
