Postdoctoral Fellow
BS, Biochemistry, Tanta University, Egypt, 2005
MSc, Biochemistry, Tanta University, Egypt, 2011
MS, Toxicology, Medical University of Vienna, Austria, 2016
PhD, Malignant Diseases, Medical University of Vienna, Austria, 2016

Mohamed A. Ahmed received his BS (2005) and MSc (2011) in biochemistry from Tanta University, Egypt. In 2016, he completed a master’s degree program in toxicology and earned his PhD (malignant diseases) from the Medical University of Vienna, Austria. During his PhD, the focus of his study was to investigate the role of FGF receptors in mediating the resistance of colorectal cancer cells to radiotherapy. In 2017, he joined Northwestern University (Chicago, Illinois) as a postdoctoral fellow, where his work focused on identifying novel targets/pathways regulated by sirtuins and elucidating their function in maintaining cellular homeostasis and uncovering their impact on cellular adaptation to stress. Subsequently, he moved to City of Hope (Monrovia, California) as a postdoctoral fellow, where he was studying oncogenic signaling and clonal evolution in B cell malignancies, including acute lymphoblastic leukemia (ALL). To further continue to broaden his career horizons in the field of cancer research, he joined the Lawlor Lab in September 2020 to investigate and understand the metabolic reprograming that mediates and promotes survival and dissemination of Ewing sarcoma cells.

Hobbies: Traveling and exploring new places, walking, hiking and playing table tennis

April ApfelbaumApril Apfelbaum, BS

Graduate Student (PhD Candidate)
BS, Cellular and Molecular Biology, Beloit College, 2017

April Apfelbaum’s research in the Lawlor Lab focuses on understanding how hijacking of normal developmental pathways leads to Ewing sarcoma oncogenesis. She is currently a PhD candidate in the Cancer Biology Program at the University of Michigan and is completing her dissertation research at Seattle Children’s Research Institute. 

Hobbies: Biking, snowboarding, crocheting and being around animals

Katherine (Kate) Braun, BS, PhD

Research Scientist III
BS, Biochemistry, University of California, Davis, 1993
PhD, Biochemistry, University of Iowa, 1998

Kate Braun’s work as a graduate student and a postdoctoral fellow at Cold Spring Harbor Laboratory focused on understanding the mechanism of DNA replication in eukaryotes. In subsequent postdoctoral work at the Fred Hutchinson Cancer Research Center, she studied cell cycle regulation in yeast. As a research scientist at the University of Washington, she studied the regulation of gene expression in response to changing nutrient conditions in yeast. Braun moved to the Fred Hutchinson Cancer Research Center to study chemoresistance in breast cancer using patient derived organoids as a senior research scientist before joining Seattle Children’s.

Hobbies: Running, hiking, snowshoeing, bread baking, reading and spending time with my family

Shireen GanapathiShireen Ganapathi, MD

Pediatric Hematology-Oncology Fellow
BA, Sociology, Emory University
MD, University of Toledo College of Medicine

Shireen Ganapathi is currently a pediatric hematology-oncology fellow at Seattle Children's Hospital who is joining the Lawlor lab as a research fellow. Prior to her medical training, she worked at the Cleveland Clinic focusing on the genomics behind cancer predisposition syndromes, and at the Albert Einstein College of Medicine understanding the role of epigenetic changes and DNA damage in aging.

Hobbies: Camping, hiking, traveling and discovering delicious new food

Nicolas GarciaNicolas Garcia, MS

Research Scientist II
MS, Ecology, Evolution and Genome Plasticity, UNSA, 2005
MS, Management of the Environment, ESC La Rochelle, 2007

Nicolas Garcia was born and raised in France and worked at the ENS Lyon before moving to the United States in 2010. He conducted research on Flavivirus at the Center for Vaccine Research of Pittsburgh and then moved to the West Coast at the Fred Hutchinson Cancer Research Center to work on T-cell therapy for solid and liquid tumors before joining Seattle Children’s.

Hobbies: Hiking and snowshoeing, his little one and board games

Jennifer JimenezJennifer Jiménez, BA

Graduate Student (PhD Candidate)
BA, Biology, Chemistry minor, Oberlin College, 2017

Jennifer Jiménez is an NIH NRSA F31 fellow in the Cancer Biology PhD Program at the University of Michigan. She is completing her dissertation research under the co-mentorship of Dr. Lawlor and Dr. Costas Lyssiotis (at the University of Michigan). Her research focuses on understanding the molecular mechanisms that drive metabolic reprograming in Ewing sarcoma to promote tumorigenicity.

Hobbies: Latin dance, cooking, running and exploring new places
