NMIN Postdoctoral Fellowship Awardees

2021 Awardees

Dr. Miffy Hok Yan Cheng has been awarded the 2021 NMIN Postdoctoral Fellowship Award in Gene Therapy for two complementary projects: Synthesis and screening of a new generation of ionizable lipids for LNP formulation, which she will pursue under the supervision of Dr. Pieter Cullis at the University of British Columbia; and Facile one-pot synthesis to radiolabel and formulate lipid nanoparticles using a microfluidic platform, which she will pursue independently.

“My research program aims to apply the principles of rational design to develop new generations of ionizable and functionalized lipids that more effectively deliver siRNA for cancer therapy,” says Dr. Cheng.

“I envision that combining traditional molecular synthetic chemistry methods with emerging nanoscale approaches will yield the next generation of lipids and LNPs with enhanced endosomal escape abilities and transfection efficacies.”

Dr. Yih Yang (Ian) Chen has been awarded the inaugural NMIN Postdoctoral Fellowship Award in Diagnostics for his project: An At-home, Self-Administered, Nucleic Acid Diagnostic Device for SARS-COV-2, which he will pursue under the supervision of Dr. Warren Chan at the University of Toronto.

“The successful completion of this project,” says Dr. Chen, “will yield an at-home nucleic acid test for SARS-COV-2 usable by people without specific training or expensive lab equipment, that will let individuals know that they are infected before they show symptoms. By promoting widespread testing, we hope to help mitigate the spread of COVID-19.”
