Wagner Lab at the 2025 Keystone Symposium – Plant Epigenetics and Epigenome Engineering

As one of the co-organizers of the 2025 Keystone Symposium – Plant Epigenetics and Epigenome Engineering, from Oct 13 to October 16, 2025, in Fort Collins, Colorado, USA, Doris attended the conference, together with Wagner Lab members: Sarah, Joy, Sandhan, Peter and Mohit (from left to right). Sandhan, Sarah and Peter presented their research from the Wagner lab with posters. Outside of the conference, they enjoyed the good food and landscapes there in Colorado.
Tian Huang at FASEB Conference 2025 – Mechanisms in Plant Development
Tian attended the FASEB Conference 2025 – Mechanisms in Plant Development, from August 24 to August 28, 2025, in Southbridge, Massachusetts, USA. He presented this Ph. D. thesis work on a poster titled “A negative feedback loop between TERMINAL FLOWER 1 and LEAFY protects inflorescence indeterminacy”.
Farewell to Dr. Tim Caspar

The Wagner Lab got together to thank volunteer Tim Caspar for his great work. During his 2 years in the Wagner Lab, he worked together with Shalini to study how the terminal flower is formed in tfl1 in Arabidopsis. He is not only an experienced biology researcher, he is also a master of mini golf, as he is the one and only two-time mini golf champion!
Dr. Shalini Yadav at IPGSA Conference 2025

Shalini attended the 2025 International Plant Growth Substances Association (IPGSA) conference, which was held from June 29 to July 3, in Fort Collins, Colorado, USA. She proudly presented her project that she has been working on here at the Wagner Lab, titled “How can indeterminate shoot be reprogrammed to become a flower?”. With her outstanding presentation, she was rewarded a Travel Award for Early Career Researchers. Great job, Shalini!
Congratulations Reginald Kwarteng

As a proud member of the Class of 2025 at Upenn, Reggie celebrated his graduation on 05/19/2025, with his family and friends, as well as the Wagner Lab members. Reggie is also one of the first to join the FERBS program of the Department of Biology. After graduation, Reggie plans to continue his research with the Wagner Lab on the regulation of LEAFY expression.
Wagner Lab welcomes Dr. Mohit Rajabhoj

As the summer starts, the Wagner Lab welcomes a new member Dr. Mohit Rajabhoj. Mohit received his Ph. D. from the Indian Institute of Science Education and Research (IISER) in Thiruvananthapuram, India. In the Wagner Lab, he will work on the mechanisms of gene expression repression and the application of epigenome reprogramming.
Farewell to Dr. Tomasz Bieluszewski


The Wagner Lab gathered to say goodbye and our best wishes to Dr. Tomasz Bieluszewski (Tomek, fourth from the right on the back row). Tomek played the most critical role in the chromatin research in the Wagner Lab. After five long years of hard work, Tomek is going back to his home country Poland, and will start establishing his own lab and continue his amazing research. We appreciate all his contributions (and the cute present he left for us), we send along with him all our best wishes and we hope to see him succeed in his career!
Penn Arts & Sciences Launches Plant ARC
The Plant Adaptability and Resilience Center (Plant ARC), led by Doris, was launched on October 14, 2024. The Plant ARC aims to enhance plant development and fortitude in the face of climate change, which impacts food security, human health, and ecosystems through more extreme and unpredictable weather events. Join us at the one-day symposium “Climate Solutions for the Living World” (register)!
