Bulun Lab Personnel

John Coon V, MS

Lab Manager

John Coon V is the lab manager and senior research technologist for the Bulun lab. He graduated with Honors in biochemistry from Knox College and received his Masters of Science degree in biotechnology from Penn State University. After graduating from Penn State, Mr. Coon joined GlaxoSmithKline as a research scientist, helping to develop novel antibiotics. Upon returning to Chicago, he joined the Bulun lab in the early spring of 2009. Mr. Coon has worked in many areas of research, but particularly enjoys the varied and challenging research of the Bulun lab.

Matthew Dyson, PhD

Research Assistant Professor

Matthew is a Research Assistant Professor in the Division of Reproductive Science in Medicine. He joined the lab in 2010 after completing his PhD in cell and molecular biology at the Texas Tech University Health Sciences Center in research focusing on the regulation of steroidogenesis. His current research interests are in defining how steroids control the retinoic acid signaling pathways that are unique to the development of the endometrium, and how dysregulation of these pathways affects the progression and maintenance of endometriosis.

Deborah Ikhena, MD

Postdoctoral Fellow

Stacy Ann Kujawa

Research Technician 

Stacy received her BS degree in Animal Sciences from the University of Illinois in Champaign-Urbana in 2005. In 2011, she was a research technician at Northwestern University for Dr. Takeshi Kurita where she consented patients for Dr. Bulun’s reproductive tissue registry and provided assistance in experiments involving fibroids and xenografting. For the last few years, she has been working in the Bulun laboratory as a research technician with her main responsibilities being consenting and maintaining the reproductive tissue registry and assisting in the laboratory in genotyping, mouse xenografting, and other experiments.​

Shimeng Liu

Graduate Student

Shimeng is currently a second year graduate student in the Driskill Graduate Program in Life Sciences at Northwestern University. She joined the group in 2014 after finishing her bachelor's degree in biology at Wuhan University in China. She is currently working on using whole genome DNA methylation methods to investigate the mechanisms underlying the formation of uterine fibroids.

Kaoru Miyazaki, MD, PhD

Postdoctoral Fellow

Kaoru received his MD degree from Keio University School of Medicine, Tokyo, Japan in 2004. After completing residency and graduate school, he received his PhD degree from Keio University in 2013. He joined the Bulun laboratory in 2015. His current research interests are in establishing the protocol to differentiate induced pluripotent stem cells into endometrial cells and defining key pathways involved in the stem cell differentiation.

Ijeoma Okeigwe, MD, MPH

Postdoctoral Fellow

Ijeoma received her MD degree from the University of California, San Francisco. After completing residency at Boston University Medical Center, she began her training at Northwestern as a clinical fellow in the Division of Reproductive Endocrinology and Infertility. She joined the Bulun lab in 2016. She is currently investigating the role of a novel PR targeted gene in uterine leiomyoma pathogenesis.​​​

Christia Angela M. Sison

Graduate Student

Christia is currently a second-year graduate student in the Driskill Graduate Program in Life Sciences at Northwestern University Feinberg School of Medicine. She completed her undergraduate studies in 2012 majoring in Biological Sciences with a minor in English at Mount St. Mary’s University in Los Angeles, CA. She joined the Bulun laboratory in 2016. Her research focus is on the transcriptional regulation of immune pathways in endometriosis.

Ping Yin, MD, PhD

Research Assistant Professor

Dr. Yin joined Northwestern as a senior research associate in November 2004. She is investigating mechanisms underlying the formation of uterine leiomyoma and exploring therapeutic strategies for its treatment.

Hong Zhao, MD, PhD

Research Associate Professor

Dr. Hong Zhao received her MD and PhD degree in China. After several years working in the Netherlands and the NIH, she moved to Chicago and began working for Northwestern University. Her research focus is in breast cancer research. Now she is working on humanized aromatase mice and tissue-specific aromatase knockout mice. She is interesting in function of aromatase on muscle, adipose tissue, breast and brain.
