Cristyn Branstetter
|
My name is Cristyn Branstetter. I grew up to in Arkansas and stayed in-state for both college and medical school. I then moved a little further south to Houston, Texas where I completed my pediatric residency training at Baylor and Texas Children's Hospital. I chose St. Jude for my fellowship due to the wide range and depth of both clinical and research opportunities that are available here. I feel very lucky to be training in a place that is both extremely academically renowned and at the same time has such a compassionate overall mission. And as an added bonus I get to be in the south where I'm close to home and family. |

Seth Karol
|
My name is Seth Karol, and I am from Ohio, growing up in Toledo and then completing medical school and residency in Columbus and Cleveland, respectively. St. Jude is the perfect fit for me because of the diversity and depth of the clinical experience combined with the fantastic research happening both clinically and in the lab. I’m very excited to be here at this wonderful hospital. |

Jamie Laubisch
|
My name is Jamie Laubisch and I grew up in Apalachin, NY. I went to Union College and was in a combined program with Albany Medical College. I completed my Pediatric Residency at Johns Hopkins and am thrilled to be at St. Jude as they have given me a chance to follow my dreams. There are endless opportunities during fellowship…I have been given the opportunity to spend time in Guatemala doing clinical research in International Oncology and Palliative Care while being mentored by some of the world’s experts in these fields. As if that was not enough, when I came here I was overwhelmed by the sense that everyone I met worked here because they love what they do and it is their passion-not their job. I am honored to be a part of this fellowship. |

Jennifer Snaman
|
My name is Jennifer Snaman. I grew up in several states as an "army brat" until my father retired outside of Washington DC when I was in high school. I returned to Virginia for medical school and moved to Boston to do my residency training at the Boston combined residency program at Children's Hospital Boston and Boston medical center. I am excited to be back in Tennessee for the third time in my life, and so glad to have opportunity to do my fellowship training at St. Jude. During my interview day, I was struck by the passion of the people who work here and connected with the mission of the hospital. I am joined in Memphis by my husband who works at cancer fundraising, and our young son, and we are excited to make this our home. |

Aimee Talleur
|
My name is Aimee Talleur. I am originally from Upstate New York, and I attended both college and medical school there. I completed my pediatric residency at Children’s National Medical Center in Washington, DC. I never thought I would move to the South, but St. Jude pulled me in from the moment my interview day started. I was drawn to the overall spirit of the program and hospital, as well as the innumerable opportunities that are available to fellows. Since my arrival, everyone has been extremely welcoming and eager to teach. I am looking forward to all that my fellowship will bring! |

Rajoo Thapa
|
My name is Rajoo Thapa. I grew up across the seven seas in the colorful land of India where I attended medical school and underwent pediatric residency training. This was followed by a second pediatric residency at Upstate Medical University, New York. Interestingly, the first time I had ever come across the words “St. Jude” was in Robbin’s Pathologic basis of disease (St. Jude’s Staging Classification for Childhood Non-Hodgkin’s Lymphoma) during my second year in medical school. A little research and I realized what St. Jude was all about and what it stood for. Currently, as a physician in training, I realize strongly than ever before that the most blessed of all get the opportunity to care for the sickest of children. This stands particularly true in the setting of an institute par excellence like St. Jude. I am confident that St. Jude would prove instrumental in my growth both in the professional front towards the realization of an accomplished career in pediatric hematology/oncology as well as in the personal front towards becoming a compassionate, grateful and a humble individual. |

Meaghann Weaver
|
Hi! My name is Meaghann Weaver. I grew up hopping across the Atlantic Ocean with my family (Britain, Azorean Islands, Ghana, Liberia, Kenya). I am now enjoying the music, food, and new bike lanes in Memphis. I attended medical school in Nebraska and pediatric residency in Eastern Virginia. What most compelled me to join the St. Jude family was the enacted, passionate commitment to applying quality pediatric oncology and palliative care in global settings. I consider it a privilege to learn from the inspiring patients and mentors and colleagues at St. Jude – a really special place to be! |

Maria Cancio
|
My name is Maria Cancio; I am originally from Puerto Rico. I did my residency training at Johns Hopkins Hospital in Baltimore, MD. I came to St. Jude for the first time 10 years ago as an undergraduate student to do research in Molecular Pathology and immediately fell in love with the hospital’s mission, the patients, and the amazing people who work so hard to make a difference. I am thrilled to be back as a fellow. |

Tamara Chang |
My name is Tamara (Tammie) Chang. I grew up in Portland, Oregon, went to college and medical school at Brown University in Rhode Island, and completed a combined internal medicine / pediatrics residency at the University of Massachusetts in Worcester, Massachusetts. I have long been interested in the late effects of cancer treatment on pediatric cancer survivors. I was drawn to St. Jude, not only for the vast opportunities for research within the areas I am passionate about, but also by the mission of this institution which resonated with me in a way unlike anywhere else. I am thrilled to be here, and to have the opportunity to train in this fantastic place! |

Ross Goshorn |
Hi, my name is Ross Goshorn. I grew up in the low country of South Carolina. For residency I escaped to the verdant Pacific Northwest and completed my pediatric residency training at Oregon Health and Science University in Portland Oregon. What struck me most on my interview day was the passion of the faculty and depth of research opportunities. No other institution could compare with the depth and breadth of the basic science, clinical and translational research opportunities. |

Carol O'Hear |
My name is Carol O’Hear. I am originally from Ft. Wayne, IN, but went to med school/grad school in Seattle, WA. I completed residency at the Boston Combined Residency Program at Children’s Hospital Boston and Boston Medical Center. I chose St. Jude because of the ability to follow and have good mentorship available for any career path in Hem/Onc. In addition, lifestyle in Memphis and at St. Jude is preferable for both pursuing my own outside interests and for quality of life for my family while in fellowship. |

Michael Walsh |
My name is Michael Walsh. I grew up between the United States and Ireland. I completed a five year combined Pediatric & Genetics Residency at Johns Hopkins Hospital in Baltimore, Maryland. I feel very fortunate to have been selected to train as a Fellow at St. Jude Children’s Research Hospital in Hematology/Oncology. My attraction to St. Jude Children’s Research Hospital is fourfold: the hospital’s mission to treat any child diagnosed with a catastrophic illness regardless of their ability to pay, the presence of leaders in the field, the success of various protocols and the potential for rapid breakthrough given the hospital’s infrastructure. |
| 3rd Year Fellows |

Cathleen Cook |
My name is Cathleen Cook. I am originally from Georgia and completed by undergraduate degree at the University of Georgia (GO DAWGS). For medical school, I trained at Penn State University College of Medicine- Milton S. Hershey Medical School in Hershey, PA (and yes, most days it does smell like chocolate in this town). For pediatric residency, I then travelled to North Carolina to train at East Carolina University- Brody School of Medicine- Pitt County Memorial Hospital. I feel blessed for the opportunity to train at St. Jude Children’s Research Hospital for my fellowship. I chose St. Jude because it is the best opportunity in the world to learn and experience Pediatric Hematology/Oncology—vast research opportunities, wonderful mentors, and fantastic supportive staff caring for the entire patient. During my second and third years of fellowship, I am participating in clinical research and also completing two graduate certificate programs in clinical research and clinical education. |

Sadhana Jackson |
My name is Sadhana Jackson and I am a third year fellow at St. Jude. I was born and raised in Gaithersburg, MD but attended pediatric residency training at Arnold Palmer Hospital/Orlando Health in Orlando, FL. I chose to complete my fellowship training at St. Jude because of the various research opportunities, wide array of patient diagnoses and overall empathetic care of the patient’s families. Currently, I’m conducting laboratory research involving the relationship of Myc medulloblastoma, the blood brain barrier and drug delivery efficacy. |

Ross Perko |
My name is Ross Perko. I grew up in Northeastern Minnesota and did both medical school and pediatric residency at the University of Minnesota. I chose St. Jude as a fellowship due to the one of a kind environment that we are able to treat our patients in. There are state of the art treatment protocols and superb outcomes in our patients. However, I feel patient’s families are cared for in such way that many of the stressors of being away from home are removed from the equation due to our exceptional ancillary staff and housing options. When Danny Thomas first dreamed of the idea of starting a children's hospital, it was originally not going to be in Memphis. He was advised to look at Memphis due to the lack of facilities in the area at that time. This spirit continues at St. Jude, one of placing resources where they are needed to support further treatment and potential cures. It is a truly inspiring environment. Memphis itself is also an incredibly diverse city, filled with important civil rights and a rich music history, great southern food and a surprisingly strong running community! After completing my first year, I am now focusing on the study of immune recovery in umbilical cord blood transplant patients in the laboratory of Dr. Mari Dallas. I also did not enter fellowship with a strong basic science experience, however the transition has been nearly seamless and is a great fit! |

Elizabeth Stewart |
My name is Beth Stewart. I am originally from Peoria, Illinois, and I completed my pediatric residency training at Phoenix Children's Hospital. I joined the Michael Dyer lab where my research focuses on the development of new therapeutics using pre-clinical models for pediatric solid malignancies. I grew up around St. Jude as there is an affiliate hospital in my hometown, and it was a dream come true to finally get the chance to work at such an amazing hospital. I love to run and I have participated in the Memphis to Peoria Run benefitting St. Jude for the past 8 years. |

Erin Sullivan |
My name is Erin Sullivan. I am originally from Worcester, Massachusetts. I did my pediatric residency at Stanford University in California. I chose St. Jude because of the diverse patient population. St. Jude has a separate outpatient clinic for Leukemia/Lymphoma, Hematology, Neuro-Oncology, and Solid Tumor. In addition, the inpatient services are divided up. I knew that I would get exposure to every diagnosis because so many patients are sent here world-wide. Currently, I am a third year fellow in Dr. Wing Leung’s lab working on Natural Killer Cells. I have never been in the lab before and after two months I have learned a lot. I am even writing a protocol to enroll patients here at St. Jude on my study. |

Susanne Wendt |
My name is Susanne Wendt. I'm originally from Germany and went to University of Leipzig for Med School where after completion I also did a doctoral thesis in a neurophysiology lab. This sparked my interest in lab research but I knew that I actually also wanted to work as a physician. I did a residency in Pediatrics and a Critical Care Fellowship at the Children's University Hospital in Mainz, Germany. I learned about St. Jude during my Oncology rotations. I visited for a 4 week internship in 2008 and I knew that this would be the place to learn about Oncology. There is no other hospital for a fellow to get more exposure to the "bread and butter" but also the rare, complex or difficult to treat patients. And there is also no other place to get a glimpse into science, become a scientist or at least understand their language whatever your plan is. I have seen no other teaching hospital offering more research opportunities and being more welcoming to a clinician. And the best of all, St. Jude is an amazing place with a great attitude towards all children regardless of ethnicity or financial background and a hospital. That's why I came to St. Jude and I didn't regret for a second. |
| 4th Year Fellow |

Liza Johnson |
My name is Liza Johnson. I am originally from Cromwell, Connecticut and completed my undergraduate degree at Vassar College. I did my pediatric residency training at the Floating Hospital for Children at Tufts Medical Center in Boston, MA after obtaining degrees in Medicine and Public Health from Tulane University in New Orleans, LA. I came to St. Jude because it combines amazing clinical experiences with endless research opportunities. The fellows I met when I interviewed were the happiest of any program I visited and this finalized my decision to come to St. Jude. Now, as a senior fellow, I can say that the support and camaraderie among the fellows are one of the program’s great strengths. I am interested in quality-of-life care in pediatric cancer and am pursuing a clinical research pathway, including a clinical project on which I am the principal investigator. With the support of the fellowship program I am also obtaining a Masters in Bioethics and I am a member of the hospital ethics committee. |
| Bone Marrow Transplant Fellow |

Edward Ziga |
Having completed my pediatric hematology/oncology fellowship at the St Louis Children’s Hospital/Washington University in St Louis, MO, I opted to continue my training in hematopoietic stem cell transplant (HSCT) at St Jude Children’s Research Hospital because of it’s pace setting role in the quest to find cures and discover modalities that will mitigate the burden of cancer and other catastrophic diseases. The opportunity to learn from and be mentored by astute physicians and scientists who are leaders in their field is unparalleled, but what strikes me most is the great philanthropic enterprise that gives afflicted children and their families the chance to receive excellent care regardless of financial status. I plan to build on my fellowship research experience from the lab of John F. DiPersio, MD, PhD where I investigated the role of interferon gamma receptor and CXCR3 signaling in murine acute Graft-vrs-Host disease models. My expectation is to be well trained in all aspects of HSCT in an environment that nurtures excellent character and a passion to help children/families plagued with these diseases find hope regardless of their outcome. I was born in Ghana where I attended the Kwame Nkrumah University of Science & Technology School of Medical Sciences. My interest in preventative medicine led to a master of public health degree at the University of Medicine & Dentistry, NJ after which I completed my pediatric residency training at the St Joseph’s Children’s Hospital, Paterson, NJ. |
| Neuro-Oncology Fellow |

Karen Tsui |
My name is Karen Tsui. I am from Auckland, New Zealand. I completed my clinical Paediatric and Haematology / Oncology training at Starship Children’s Hospital, Auckland. In addition I have an interest in infections in the immunosuppressed group, and partook in a year of Infectious Diseases elective training. I feel extremely privileged to work and contribute in a world renowned Brain Tumour Research Centre, which has protocols that have seen improved survival rates in children diagnosed with common and rare brain tumours. I am thrilled with the opportunity to learn, and hope to bring these skills and experience home to help our kids. I have been involved in epidemiology research of brain tumour in NZ, and developed an interest in the unique incidence and survival of medulloblastoma in Maori children, our native population. I am certain the experts at St. Jude will provide me with insight and directions into further research in this area. |
| Global Health Fellow |

Alia Zaidi |
My name is Alia Zaidi. I am originally from Pakistan. I trained in hematology and oncology in U.K at the University of Newcastle in Newcastle-upon-Tyne. I then worked for 8 years as a pediatric oncologist in Pakistan . It is only when you are struggling in a developing Country with limited resources, that you realize the true importance of a shining beacon like St Jude. Cure4kids is literally a lifeline for pediatric oncologists in many countries that are officially not affiliated with St Jude. So when I came to USA, I knew this was the ideal place for me if I am to achieve my goal of improving cancer care for children of Pakistan. Having come here, I feel extremely fortunate that I now have the opportunity not only of academic growth but also of developing excellence as a human being . Never before have I seen such humbleness and genuine compassion in so many people under the same roof, who are also undoubtedly the very best in their field. The compelling beauty of this place is that whereas it is at the forefront of cutting edge research, it still finds the time to look around and hold out a strong helping hand to all those who are less fortunate …… and this great humanitarian spirit is obvious in everyone that is anyone at St Jude. I am thrilled to be a part of this fantastic institution. |
