Lionel Chow, MD, PhD
Assistant Professor of Pediatrics
Cancer and Blood Diseases Institute
Division of Hematology/Oncology
Cincinnati Children’s Hospital Medical Center

Dr. Chow received his medical and graduate research training at McGill University in Montreal, Canada. He subsequently completed clinical training in Pediatrics followed by Pediatric Hematology and Oncology at the Hospital for Sick Children in Toronto, Canada. Further research training focused on brain tumors was obtained at St. Jude Children’s Research Hospital in Memphis, TN.

Dr. Chow is now at Cincinnati Children’s Hospital Medical Center and the University of Cincinnati where he heads a research laboratory investigating a particularly aggressive form of brain cancer in children called High-Grade Glioma (HGG). Diffuse Intrinsic Pontine Glioma (DIPG) is one type of HGG with a particularly devastating outcome in children. Using a combination of laboratory models for the disease and human tumor specimens, Dr. Chow hopes to gain a better understanding of this terrible disease in order to design new and more effective ways to treat patients.

Dr. Trent HummelKevin Bucholtz, Ph. D.
Chair and Associate Professor
Department of Chemistry
Director of Undergraduate Research
Mercer University

Dr. Bucholtz received his B. S. in Chemistry at Gannon University in Erie, PA. He completed his M. S. and Ph. D. in Chemistry at the University of Rochester in Rochester, NY. His thesis work investigated the design and synthesis of a small molecule receptor to bind to Lipid A for integration into biosensors for Gram (-) bacteria.

Dr. Bucholtz began his academic career as an Assistant Professor of Chemistry at Mercer University in Macon, GA. He has become tenured and promoted to Associate Professor and subsequently selected as the chair for the Department of
Chemistry. His research interests focus on problems in bio-organic chemistry and specifically in collaboration with James Thomas in the Mercer University School of Medicine, investigating the development of novel inhibitors of 3-β-hydroxysteroid dehydrogenase as a potential treatment for hormone sensitive breast tumors. He also was appointed as the Director of Undergraduate Research in the Senior Vice Provost's Office for Research. In this position, Dr. Bucholtz helps facilitate and oversee undergraduate research initiatives and programs.

Dr. Anna Janss, MD, PhDDr. Anna Janss, MD, PhD
Children’s Healthcare of Atlanta
Associate Professor
Pediatric Neuro-Oncology
Emory University School of Medicine
Atlanta, GA

Dr. Janss received her PhD and MD degrees from the University of Iowa. She completed a residency in Neurology at the Hospital of the University of Pennsylvania in Philadelphia, PA followed by a fellowship in Pediatric Neuro-Oncology at the Children’s Hospital of Philadelphia. Dr. Janss joined Children’s Healthcare of Atlanta in 2003.

Her main clinical interests lie in pediatric neuro-oncology, the late effects of cancer therapy and paraneoplastic disorders. She has done extensive research on various aspects of pediatric neuro-oncology, including primitive neuro-ectodermal tumors and cancer treatment methods.

Dr. Annie A. Huang, MD, PhDDr. Annie A. Huang, MD, PhD
Principal Investigator
The Arthur and Sonia Labatt Brain Tumor Research Centre
Assistant Professor
Department of Pediatrics
University of Toronto
Toronto, Ontario, Canada

Dr. Huang received her PhD and MD degrees from the University of Toronto. Following residency training in Medical Genetics and Pediatrics at The Hospital for Sick Children in Toronto, she completed fellowship training in Pediatric Hematology/Oncology at The Hospital for Sick Children and a post-doctoral fellowship at the Ontario Cancer Institute, Princess Margaret Hospital. Dr. Huang was appointed to the Pediatric Brain Tumor Program of The Hospital for Sick Children in Toronto in July, 2002 as a Clinician Scientist.

Her lab is interested in mechanisms that underlie progression in primitive neuroectodermal tumors (PNETs), the most common group of pediatric malignant brain tumors. Due to the devastating consequences on the developing brain of the best current treatment, which includes radiation, there is much interest in uncovering molecular pathways that specify aggressive behavior in PNETs in order to ultimately develop more effective and less toxic treatments for such tumors. Current research focuses in part on the role of c-Myc, a potent oncoprotein, in specifying aggressive behavior in PNETs.

Division of Oncology
Cincinnati Children's Hospital Medical Center

Dr. Hummel received his medical training at the University Of Cincinnati College Of Medicine in Cincinnati, Ohio.  He completed his clinical training in Pediatrics at Akron Children’s Hospital in Akron, Ohio.  This was followed by a Pediatric Hematology and Oncology fellowship at Cincinnati Children’s Hospital Medical Center in Cincinnati, Ohio where he performed neurobiology research. 

He now focuses his clinical research at Cincinnati Children’s Hospital on developing novel therapeutics to treat children with central nervous system tumors including those with very poor prognosis tumors such as high-grade gliomas and diffuse intrinsic pontine gliomas.  Dr. Hummel is active in the DIPG online community and is a physician contributor to the DIPG support group as well as a moderator at


Dr. Trent HummelOren J. Becher, MD
Assistant Professor
Division of Hematology/Oncology
Department of Pediatrics
Duke University School of Medicine
Chapel Hill, NC

Dr. Becher received his medical degree from Johns Hopkins University in Baltimore, MD and residency in Pediatrics from Children’s National Medical Center in Washington, DC. He completed his fellowship training in Pediatric Hematology/Oncology and Pediatric Neuro-Oncology at Memorial Sloan-Kettering Cancer Center in New York, NY where his research focused on gliomas in children. Dr. Becher joined Duke University in 2010.

Dr. Becher’s laboratory interests are to apply genetic mouse models of pediatric brain tumors to prioritize the translation of novel agents into clinical trials. In particular, his laboratory is using a genetic mouse model of Diffuse Intrinsic Pontine Gliomas (DIPG) to determine therapeutic targets, unravel ways to bypass the blood-brain-barrier, and investigate region-specific differences between gliomagenesis in the brainstem and the cortex. His laboratory is also developing improved genetic mouse models of DIPG and applying them as preclinical tools to help prioritize the translation of novel agents into clinical trials for DIPG. Moreover, his lab is interested in investigating mechanisms of resistance towards novel targeted agents.

Columbus, OH

Dr. Johnson received his PhD degree in Neuroscience from the Weill Cornell Graduate School of Medical Sciences in New York, NY investigating the transcriptional regulation of the MDR1 gene by the p53 family of proteins (p63 and p73).  He continued these studies as a post-doctoral fellow at the Fox Chase Cancer Center in Philadelphia, PA and the Cancer Institute of New Jersey in New Brunswick, NJ.  Interested in pediatric brain tumor development he continued his post-doctoral career in the Developmental Neurobiology department at St. Jude Children’s Research Hospital in Memphis, TN.  In 2010 he became a Principal Investigator at The Research Institute at Nationwide Children’s Hospital.

Dr. Johnson helped to develop the first mouse model for ependymoma, the third most common pediatric brain tumor and the most common adult spinal cord tumor.  Up to 40% of cases are incurable and chemotherapy for the most part is ineffective. His laboratory is currently investigating the signaling pathways and genetic mutations involved in the development of this disease in hopes of identifying alternative treatment options.
