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

Alan Futran

Alan Alan is a sixth-year graduate student in the Link Lab. He grew up in Westfield, New Jersey and graduated from the University of Pennsylvania in 2010 with a B.S. in Chemical and Biomolecular Engineering. As an undergraduate, Alan did research in the areas of biotechnology and protein engineering and interned at Centocor, where he worked on cell line development. Alan is co-advised by Professor Link and Professor Stanislav Shvartsman. His research focuses on protein interactions involved in the MAPK signaling pathway.

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 examines the effects of selective mutagenesis on the structure and antibacterial properties of lasso peptides.

Joseph Koos

Joe Joe is a fourth-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 fourth-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 is excited to be starting research in the field of protein stapling via bioorthogonal chemistry. 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 second-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.

Current undergraduate students

Kenneth Hubbell '16


Kenny Kenneth came to Princeton from Anchorage, Alaska to study Chemical and Biological Engineering. He is pursuing certificates in Global Health and Engineering biology, and has spent his last few summers doing biological research at Penn State and Merck. His work in the Link lab is focused on the potential of lasso peptides to serve as scaffolds for pharmaceutically relevant peptide sequences. In his spare time, he can be found working in the pottery studio, hiking with Outdoor Action, or cooking needlessly complex meals with friends.

Caroline Kim '16


Caroline Caroline is a senior in the Molecular Biology department from Memphis, TN. She has done research at the Korea Center for Artificial Photosynthesis on photocatalytic water splitting. Outside of lab, she enjoys getting lost in foreign countries, water gun fights, and napping.

Jason Qin '16


Jason Jason is a senior in the Department of Chemical and Biological Engineering, pursuing certificates in the Applications of Computing and Engineering Biology. He has previously done research in the fields of metabolic engineering and computational chemistry. Outside of the classroom, Jason is a Residential College Adviser in Rockefeller College, and is involved with both AICHE and the Princeton Biomedical Engineering Society.

Chad Wangsanuwat '16


Chad Chad is a CBE undergraduate senior with certificates in Engineering Biology and Engineering Management Systems but is way too interested in learning languages. He is from Bangkok, Thailand and absolutely suffers every time he flies long distance. He spent one summer in Japan and Germany each. Outside of lab, he is a social chair at Princeton Quadrangle Club and is an interactor for SEAS. In his free time, he likes to play board games or keeps up with current issues mainly about Thailand. He manages to somehow incorporate watching TV shows and doing cardio in his weekly schedule.

Lawrence Yu '16


Lawrence Lawrence is a senior in the CBE department. Originally from sunny southern California, he has attempted to love the seasons here on the east coast. In the past few summers, Lawrence has worked in a variety of places like Chattanooga, Hong Kong, and Boston, and he is unsure where he’ll end up next. Outside of lab, he is also an officer of the Materials Research Society on campus and does a lot of photography and cooking.
