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 and professor in 2018.

Current postdocs

Hader Elashal

Hader Hader is a Postdoctoral Research Associate in the CBE Department. She grew up in New Jersey and earned her B.S. and Ph.D. from Seton Hall University. Her dissertation focused on rationalizing the development of an artificial chemical protease (cyclic urethane), executing its synthesis, and probing its selectivity, reactivity, and applicability to a variety of applications. She is excited to be a part of the Link lab and hopes to complement her chemistry training with a new toolbox of biochemical engineering tools. Outside of the lab, she likes to read and bake.

Current graduate students

Joseph Koos

Joe Joe is a 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.

Wai Ling Cheung

Wai Ling Wai Ling is a fifth-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.

Larry So

Larry Larry is a second-year graduate student in the Chemical and Biological Engineering department, from Hong Kong. He graduated in 2017 from the University of Cambridge in Chemical Engineering with a BA/MEng with previous work in bioinformatics. Outside of work, he likes to run and play tennis.

Li Cao

Li Li is a first-year graduate student in the CBE department. He grew up in Shanghai, China, and moved to San Jose, California when he started college. He graduated from the University of California, Berkeley with a B.S. in Chemical and Biomolecular Engineering and a concentration in biotechnology. His undergraduate research involved synthesizing alkyne derivatives to improve Raman Imaging efficacy and analyzing inertial migration entry lengths of bi-disperse microspheres. Outside of lab, he enjoys traveling and weightlifting."

Current undergraduate students

Moshe Beiser '19


Moshe Moshe is a member of the class of 2019 in the Chemistry Department. He has spent summers conducting research in Organic Polymer Synthesis and Ovarian Cancer Research, and is ultimately interesting in going to med-school and becoming a practicing physician. Outside of the classroom, he is involved with programming at the Center for Jewish Life and enjoys playing baseball, basketball, and eating fancy, pickled fish.

Annie Wang '19


Annie Annie is senior in the CBE department carrying out her thesis research in the Link lab. Previously she has worked on research projects on bacterial surface attachment, myb fusion proteins in leukemia, and fluorescent dye for imaging ureters in real time and intraoperatively. Ultimately she would like to work in industry for a couple years before deciding on grad school or pursuing a degree in the medical field. Outside of class, Annie also enjoys singing and visual arts.
