Principal investigator

Professor A. James Link

207 Hoyt Laboratory


Professor Link grew up in Newburyport, MA and obtained his B.S.E. in Chemical Engineering from Princeton University in 2000. Following undergraduate studies, he moved to southern California to pursue a Ph.D. in Chemical Engineering at Caltech under the direction of David Tirrell. After receiving his Ph.D. in 2005, Prof. Link was an NIH Kirschstein Fellow at the University of Texas, Austin, in the lab of George Georgiou. He began his appointment as assistant professor of Chemical and Biological Engineering at Princeton in July 2007 and was promoted to associate professor in 2013.

Current graduate students

Caitlin Allen

Caitlin Caitlin Allen hails from New Mexico, where she obtained a B.S. in Chemical Engineering from the New Mexico Institute of Mining and Techonology. She has worked for five years as a technical intern at Sandia National Laboratories, and spent two years studying liposomal drug delivery at her undergrad. Her current research project involves the construction of new peptide topologies based on the rotaxane structure of lasso peptides.

Joseph Koos

Joe Joe is a fifth-year graduate student in the Molecular Biology department. He grew up in Fort Ann, NY and moved across upstate NY to attend Colgate University, where he received a B.A. in biochemistry. Before coming to Princeton, Joe spent time doing research at the NIH and Colgate during undergraduate as well as two years as a technician at Memorial Sloan Kettering working in a crystallography lab. Outside of lab, he likes to read or go biking.

Frank Piscotta

Frank Frank is a fifth-year graduate student in chemical and biological engineering from Secaucus, NJ. He received his B.E. in chemical engineering from the Cooper Union in New York, NY and works on a wide variety of projects in the lab. Outside of the lab he enjoys playing sports and hopes the Rangers win the Stanley Cup every year.

Chuhan Zong

Chuhan Chuhan Zong is from the lovely city Chongqing in China. She attended the University of Minnesota for college, where she obtained her BS in Chemistry and Biochemistry. She has worked at the Mayo Clinic, where she conducted research on protein engineering and breast cancer. She loves music and especially enjoys playing the guitar and keyboard. She also likes food and travel.

Wai Ling Cheung

Wai Ling Wai Ling is a third-year CBE graduate student from Brooklyn, NY. She graduated in 2010 from Princeton University with a B.S.E. in Chemical Engineering and a certificate in engineering biology. She has previously worked in the Link Lab for two years, where she studied the lasso peptide maturation of microcin J25 for her senior thesis. After her undergraduate studies she first worked at Exelus Inc. on heterogeneous catalysts for one and a half years followed by two and half years at Rinat, Pfizer on protein engineering. She is excited to be back.
