Artem Barski, PhD, is interested in epigenetic and transcriptional regulation of gene expression. During his post-doctoral training in Keji Zhao lab at NIH, Dr. Barski took part in the development of ChIP-Seq, a revolutionary method that combines ChIP with the next-generation sequencing. ChIP-Seq allows genome-wide mapping of chromatin modifications and transcription factor binding sites with resolution and sensitivity far exceeding older methods. Together with his NIH colleagues Dr. Barski used this approach to map more than 40 chromatin modifications in human T cells, which fundamentally improved the understanding of epigenetic regulation of transcription. Dr. Barski has since been using ChIP-Seq and other sequencing-based genome-wide methods to understand the role of chromatin modifications in gene regulation. His most recent work includes investigation of chromatin regulation of genes transcribed by RNA Polymerase III and the discovery of gene poising in T cells.
Since his arrival to Cincinnati Children’s Hospital Medical Center in 2011, Dr. Barski is utilizing ChIP-Seq, RNA-Seq and other cutting-edge approaches to understand epigenetic basis of T cell activation, memory and tolerance.

Patricia C. Fulkerson, MD, PhD, is an assistant professor of pediatrics at Cincinnati Children’s Hospital Medical Center within the University of Cincinnati College of Medicine. Her PhD under the mentorship of Dr. Marc Rothenberg was focused on the analysis of experimental allergic lung inflammation in mice. She made a series of groundbreaking observations including a novel approach to understanding the complex and coordinated interplay of the chemokine family of cytokines and eosinophils in experimental allergic lung disease. Throughout her graduate studies, Dr. Fulkerson was recognized as a top trainee in the laboratory. Nationally, she was selected for competitive awards; her most distinguished award was the Serono Ian Clark-Lewis Memorial Award, provided to a trainee for the best talk at the Keystone Symposium Chemokines & Chemokine Receptors. Locally, she has received several competitive awards and scholarships including the Physician Scientist Training Program Scholar Award, as well as prizes for participation in research forums. Upon completion of the MD/PhD program, Dr. Fulkerson completed a research-track pediatric residency. She was recognized as being an outstanding resident and was awarded the Thomas F. Boat Pediatric Pulmonology Award in her final year of residency.
Dr. Fulkerson's innovation and dedication to research continued to be recognized during her allergy/immunology fellowship; she received the AAI-Life Technologies Trainee Achievement Award from the American Association of Immunologists in 2011, and she has the distinction of having achieved extramural funding during her first year of clinical fellowship, with the NIH awarding her a K08 grant on her first application. This independent funding at such an early stage is a notable accomplishment. Now, as an assistant professor, Dr. Fulkerson’s independent research program is focused on the biology of the eosinophil lineage-committed progenitor (EoP). Her overall aim is to identify novel therapeutic targets to block eosinophil production for the treatment of patients with eosinophilic disorders. She has developed a number of innovative methods to study the regulation of eosinophil development including liquid culture systems to follow differentiation of both murine and human EoPs into mature effector eosinophils. The pathways that are identified in her culture systems are tested in models of hypereosinophilia, infection, and allergic inflammation to further characterize the clinical and therapeutic potential of candidate targets.

Leah C. Kottyan, PhD
studies the molecular and immunological mechanisms driving the statistical association of genetic variants with systemic lupus erythematosus and eosinophilic esophagitis. The goal of her research is to refine the statistical analysis of genetic data while using analytical and biological tools to predict and confirm genetic variant-dependent differences that affect gene expression, cell function, and disease risk.
Genetic basis of lupus; genetic basis of eosinophilic esophagitis; immunological mechanisms mediating genetic association with disease
Visit the Kottyan Lab.
For the past decade, many geneticists have approached genetic analysis with the idea that they simply need to increase statistical power by enlarging the sample size (e.g. ~100,000 person height GWAS) and assess enough loci in order to find the “genes” associated with a disease. Unfortunately, clinicians can do relatively little with this type of correlative genetic information. Dr. Kottyan recently lead a genome-wide association analysis of eosinophilic esophagitis in which they went beyond the identification of nine new risk loci and identified the molecular, tissue-specific mechanisms through which genetic variants at the CAPN14 locus increase risk of disease.
During her post-doctoral fellowship, she optimized statistical modeling strategies using genetic data from large multi-ancestral cohorts to identify candidate genetic causal variants through complementary frequentist and Bayesian approaches. In genetic analysis, it is easy and even tempting to make a story out of a genetic variant that seems important. Using two types of statistical analyses on multiple cohorts of different ancestry helps to avoid the misplaced attribution of causality. Instead, Dr. Kottyan’s group develops a short list of variants that are most statistically likely to be causal before they start biological or functional analysis. Once identified, the group predicts and confirms biological phenotypes that are affected by the risk variants.

During the residency program, Dr. Risma was awarded the pediatric resident teaching award by the medical students. She also engaged in translational research studies related to the genetics of asthma under the mentorship of Dr. Gurjit Hershey, resulting in a first author publication as a pediatric resident.
In 2000, Dr. Risma was accepted to the Allergy and Immunology Fellowship Program at Cincinnati Children’s. In addition to her clinical training, she pursued an innovative research project under the mentorship of Dr. Janos Sumegi and Dr. Alexandra Filipovich. She proposed a mechanism to study the structural and functional impact of perforin missense mutations identified in patients with hemophagocytic lymphohistiocytosis. In 2004 she was awarded the Nezelof Prize for best scientific presentation at the international meeting of the Histiocyte Society. The culmination of her fellowship research project was published in the Journal of Clinical Investigation, 2006.
Upon completion of her fellowship in 2005, Dr. Risma was appointed as an assistant professor in the Division of Allergy and Immunology at Cincinnati Children’s Hospital Medical Center within the UC Department of Pediatrics. In 2006 Dr. Risma received a Clinical Scientist Development Award from the Doris Duke Charitable Foundation.

Ting Wen, PhD Researcher, Cincinnati Center for Eosinophilic Disorders
investigates the molecular mechanisms of eosinophilic esophagitis (EoE). His lab's studies focus on identifying novel disease-causing genes and related pathogenic pathways. His research utilizes genome-wide analysis and cutting-edge techniques to provide molecular insight into the pathogenesis of EoE and allergy. Investigating basic eosinophil biology with human samples and mouse models is also an ongoing research interest.
Researcher, Cincinnati Center for Eosinophilic Disorders
Ting Wen, PhD, has characterized the unique, tissue-specific transcriptome of purified murine eosinophils under homeostasis and allergic conditions and demonstrated the expression and function of a couple of unexpected molecules, CD22 and CAR4, on gastrointestinal and lung eosinophils, respectively (Wen et al., 2012 and 2014, Journal of Immunology).
Dr. Wen also developed a murine eosinophil transfer model system that has proven to be useful in assessing the function of a gene of interest that is expressed on eosinophils or target tissue (Wen et al., 2013, PNAS).
Dr. Wen is a co-inventor of the EoE Diagnostic Panel (EDP), created in part due to his expertise in molecular biopsy and bioinformatics. The Cincinnati Children's-owned patent is now licensed to the diagnostic company Diagnovus, LLC, as Engauge GI-EoE test and is in use in clinical practice (Wen et al., 2013, Gastroenterology).
In the past three years, Dr. Wen won the following awards for his eosinophil-related studies:
Dr. Wen has also been an invited speaker on several national and international meetings related to eosinophilic disorders and co-authored to two book chapters.
