Lab Members

Winnie Wan-yee Tang, PhD
Associate Professor
Department of Environmental Health Sciencesw-tang

Dr. Tang received her PhD from the Chinese University of Hong Kong in 2004. Dr. Tang obtained tremendous experience in epigenetics and environmental health sciences during her postdoctoral training (2004-2010) at the laboratory of Prof. Shuk-mei Ho at University of Cincinnati Department of Environmental Health. With the support of the NIEHS-funded Pathway to Independence Award (R00), Dr. Tang established her laboratory at the Johns Hopkins Bloomberg School of Public Health in the Department of Environmental Health Sciences in the Fall of 2010. 

Winnie’s current research interest is deciphering how environmental pollutants alter the epigenome via DNA de/methylation and chromatin remodeling, leading to cancer or other common diseases like asthma, cardiovascular diseases and sleep apnea. Her research findings may lead to the development of improved preventive measures and therapeutic strategies to reduce the burden of chronic diseases. Also, she aims to translate our scientific findings into human so as to provide proper disease management and lifetime recommendations to the public in order to improve public health.

Outside lab, she likes cooking, reading, yoga and watching movies (especially Sci-Fi movies).

bonnieBonnie Ho-yee Yeung, PhD
Postdoctoral Fellow

Dr. Yeung received her PhD at The University of Hong Kong in the field of endocrinology and cancer research. In 2014, she and her family moved to the States and joined Dr. Tang’s lab in the Department of Environmental Health Sciences since 2015.

Her current research is focusing on the effects of environmental exposures to house allergen and persistent organic pollutants (POPs), on lung function through epigenetic mechanisms.  

When not in the lab, she enjoys spending time with her family, traveling and watching movies.

sunQinying Sun, MS
Visiting Scholar

Qinying received her Master Degree in Clinical Medicine from Second Military Medical University, Shanghai, China. Aside from her clinical duties, she participates in lab research and focuses on the studies of airway inflammation. Since May 2016, she has joined Dr. Tang’s lab as a visiting scholar.

Qinying's current research is focusing on the epigenetic regulation of asthma pathogenesis. She is also interested in how environmental pollutants cause lung cancer through epigenetic modifications via non-coding RNAs.

Her hobbies include walking and watching movies.

Xiaoqing Ouyang, MS
Visiting Scholar

Xiaoqing holds Master's in Analytical Chemistry and is currently a lab technician at Department of Chemistry in the Xiamen University, China.
She has more than ten years experience in the measurement of  environmental toxicants such as pesticides, heavy metal ions and antibiotics in food and biospecimens (urine and blood) using High performance liquid chromatography mass spectrometry (HPLC-MS).

She joined Dr. Tang’s lab in July 2016. In Dr. Tang’s lab, her research focuses on the development of a reliable LC-MS method for the sensitive and accurate quantification of 5-cytosine derivatives in biospecimens. 

Xiaoqing enjoys reading, hiking, watching movies and listening to music.

Breanna Thomas
Summer Intern
(Diversity Summer Internship Program 2016, JHSPH)

Breanna is a rising senior at Xavier University of Louisiana majoring in Biology with a minor in Chemistry.

Since May 2016, she has been mentored by Dr. Tang on her 10-week graduate-level biomedical research. Her project is to study the maternal effect of house allergen on epigenetic changes and asthma susceptibility of the offspring. She learns various molecular biological techniques such as nucleic acid isolation, cDNA synthesis, qPCR and Methylation Specific qPCR to quantitatively measure the expression and promoter methylation of various candidate genes that are associated with asthma pathogenesis. Breanna aspires to serve the community through research and primary care.

Outside of the lab, Breanna enjoys reading and spending time with family and friends.

Peter Yunhan Yang
Summer Intern
(DREAM Summer Internship Program 2016, CUHK)peter

Peter is a rising senior at the Chinese University of Hong Kong (CUHK), majoring in Biochemistry with a minor in French. In this summer, he works with Drs. James Sham and Winnie Tang on a project examining the epigenetic regulation of transient receptor potential cation channel subfamily M member 8 (TRPM8) in pulmonary arterial smooth muscle (PASM) cells of rats with pulmonary hypertension and its effect on PASM cell phenotypes.

Outside the lab, he likes hiking, cooking, reading detective novels and learning new languages.
