About P.O.C.C.

The Philadelphia Organic Chemists' Club (POCC) is one of the oldest independent chemistry clubs in the United States and it works in conjunction with area universities and pharmaceutical companies to allow distinguished scientists to speak to a broad chemistry audience from the Philadelphia area. The organization's central purpose is to facilitate the interaction between scientists, particularly between academic and the numerous chemical and pharmaceutical companies. The POCC lectures and events provide a monthly forum.
The POCC has been actively sponsoring seminars in Philadelphia since at least 1945 (check out the archives!). Typically, the POCC meets on the last Thursday of the month, often with the speaker being hosted during the day by one of the local chemical or pharmaceutical companies. The POCC event is held in the University of Pennsylvania Chemistry Department, beginning at 6:30 p.m. with a social hour, followed by the seminar at 7:30 p.m.

Meet the POCC Leadership

Jing Li

Chair, President of Pharmablock USA

Jing is currently president of PharmaBlock(USA) focusing on team building, process capability building and site expansion. Prior to work at PharmaBlock since 2016, Jing had over eight year API process development experience with Merck, led and supported many API development projects. She also had six years medicinal chemistry experience and advanced two molecules into clinical stage. Jing graduated from Nanjing University (China) with PhD in Chemistry, and had postdoc training with Prof Patrick Harran on total synthesis of Diazonamide A. She lives in Worcester PA, with her husband, two daughters and three furry friends. She enjoys reading, traveling and horse riding.

Qishui (Tracy) Chen

Assistant Secretary, Technology Licensing Officer @ the University of Pennsylvania

Tracy is a technology licensing officer at University of Pennsylvania. At Penn Center for Innovation (PCI), she manages intellectual property protection, licensing, and commercialization for a variety of technologies in chemistry, materials science, biotechnology, and engineering. Prior to working in technology transfer, Tracy was a postdoctoral researcher at Northwestern University with Prof. Fraser Stoddart, studying mechanically interlocked molecules in metal organic frameworks. She interned at the Office of Innovation and New Ventures (INVO) at Northwestern, where she conducted prior art search and market analysis for new inventions. Tracy received her PhD in organic chemistry in 2015 from Columbia University (advisor: Colin Nuckolls), and her BS in chemistry from Tsinghua University in Beijing, China.

Christopher Kelly

Web Master, Scientist @ Janssen R & D

Chris grew up in Yorktown Heights, NY, a suburb of one of the greatest cities in the world. Chris’s interest in organic chemistry was sparked during his undergraduate studies at Stonehill College in North Easton, MA. At Stonehill, Chris worked under the mentorship of Prof. Leon Tilley and completed a targeted synthesis of a previously unknown bicyclobutane derivative, 1-(trifluoromethyl)bicyclo[1.1.0]butane. After graduating summa cum laude and valedictorian of his class, Chris moved to the University of Connecticut to perform his doctoral work under Prof. Nicholas Leadbeater. At UCONN, he worked toward developing practical methods in the areas of organofluorine chemistry, sustainable oxidative processes, and the integration of emerging technologies (continuous flow processing, microwave irradiation, etc.) in synthesis.

In 2015, he moved to Philadelphia to pursue his post-doctoral training as an NIH Postdoctoral Fellow under Prof. Gary Molander at the University of Pennsylvania. At Penn, Chris’s research centered on the utilization of photoredox catalysis as an enabling technology for C–C bond construction and its application toward accessing novel fluorinated motifs. In the summer of 2018, Chris will move to Richmond, VA to join the faculty at Virginia Commonwealth University and the Medicines for All Institute. At VCU, Chris’s group focused on reaction discovery by leveraging high throughput experimentation, computational insight, and cutting-edge equipment with the ultimate goal of developing tools to solve problems in medicinal chemistry. In the fall of 2019, he left VCU to join Janssen's new Discovery Process Research team headed by Jaume Balsells to tackle problems durectly relating to human health.
