Our Fellows & Activies

First-year fellows

Julia Haston, MD
Medical School: Quillen College of Medicine, East Tennessee State University
Residency: Medical University of South Carolina

I knew I wanted to become a pediatrician from a very young age, but it wasn't until my Pediatric residency that I realized my interest in Pediatric Infectious Diseases. I grew up in a small town in east Tennessee, attended Clemson University for college, and returned to Tennessee for medical school where I was first exposed to the world of infectious diseases. Throughout medical school, residency, and my Chief residency, I developed a strong interest in tropical infections and parasitology, global health, and public health. Although I'm just starting to search for my niche within the field, I know that Emory has extensive opportunities to help me become an excellent clinician, find an area of research that is globally relevant, and further my education in public health and epidemiology. I'm so excited to be at Emory for this next step in training! I come to Atlanta with my husband, young daughter, and dog, and we are looking forward to exploring all that the Atlanta area has to offer!

Cassie Grimsley-Ackerley, MD
Medical School:  Medical College of Georgia
Residency:  Medicine & Peediatrics, University of Cincinnati Children's Hospital

I grew up in Columbus, Georgia and stayed close to home for both college and medical school. Subsequently, I ventured out and completed my Med-Peds residency training in Cincinnati, Ohio. Throughout my time in college and medical school, I was awarded the opportunity to travel to resource-limited areas within southern India, Swaziland and Ecuador. Interacting with individuals suffering from poor sanitation and treatable diseases fostered my interest in Infectious Disease and Public Health. I am currently one of the combined adult and pediatric ID fellows. I have strong interests in HIV, immunology and vaccinology. Outside of work, I enjoy planting in the garden, wine-tastings, sewing, reading historical fiction, and eating out with friends.

Second-year fellows


Deborah Bloch, MD
Medical School/Graduate School: Ben-Gurion University of the Negev Faculty of Health Sciences, Israel
Residency: Pediatrics, St. Christopher's Hospital for Children

I'm originally from southern New Jersey, right outside of Philadelphia. My interest in infectious diseases started while attending college in New York City and gaining exposure to HIV advocacy.  International Travel, medical school in Be'er Sheva, Israel and my pediatrics residency in Philadelphia, PA all served to reinforce my career choice.  While in fellowship, I'd like to study immunoparasitology and global health, specifically HIV co-infections and syndemics, as well as the anthropolgy and social determinants of health surrounding infectious diseases. I'm excited to be at Emory, close to the CDC, and to explore Atlanta and the surrrounding areas.  I hope to complete the Masters of Science in Clinical Research program.

Vanessa Raabe, MD, Msc
Medical School: University of Minnesota
Residency: Medicine & Pediatrics, University of California San Diego

I grew up in St. Paul, Minnesota. Since finishing college, my career has taken me to the London School of Hygiene and Tropical Medicine to pursue an MSc in control of infectious diseases where I did research on ways to make infection control more culturally acceptable during Ebola outbreaks, back to Minnesota for medical school, and then to southern California, where I completed a med-peds residency at University of California – San Diego. I am currently pursuing both adult and pediatric infectious diseases through a combined med-peds ID fellowship at Emory. My interests are in travel and tropical medicine and emerging/re-emerging infections -- particularly viral hemorrhagic fevers. When not at work, I enjoy traveling, reading, hiking, and exploring restaurants around Atlanta.

Third-year fellows

Su Jin Joo, MD
Medical School: Yonsei University, Seoul, South Korea
Residency: Pediatrics, Maimonides Infants & Children's Hospital, Brooklyn, NY

I am originally from Seoul, South Korea, but certainly have moved around quite a bit! I spent my formative years in the US (NY, MA, RI), and after college, my family moved back to Seoul where I went to medical school. I came back to US for Pediatric residency training in Brooklyn. After living in NYC for 4 years (3 years of residency plus chief year), I was ready for warmer weather! I chose Emory for its strong clinical training and various research opportunities. I am currently working with Dr. Cegielski at CDC/TB branch looking at TST results as a predictor of outcomes in active TB patients in US. I hope to further pursue my career in global health and epidemiologic research. On weekends, I enjoy going to the High Museum of Art, painting and drawing, and trying out new restaurants. 
Chris Prestel, MD
Medical School: Wayne State University School of Medicine, Detroit, MI
Residency: Pediatrics, Medical University of South Carolina
After completing undergrad and medical school in Michigan, I was ready for a change of scenery (temperature!) and migrated to South Carolina where I completed my Pediatrics residency at the Medical University of South Carolina.  There I learned the joys of temperate winters while learning to take care of sick children.  I've had several trips to developing countries for medical work.  There I began to study tropical diseases, parasites, and problems that affect underserved areas.  This is one of the reasons I chose Emory due to their heavy involvement in research around the world and with tropical diseases, as well as the opportunities to be involved in that. I enjoy doing anything outdoors and I am excited to find the mountain bike trails nearby and hopefully take some weekend trips to the mountains.
