Congratulations to Dr. Helna Baby on successfully defending her doctoral thesis! Helna’s work ranged from engineering of PLGA microparticles for targeted delivery of RhoA to nucleus pulposus for IVDD therapy to charge-reversed exosomes for mRNA gene delivery to cartilage for OA therapy. Helna’s dedication and unrelenting effort are traits we are greatly admire and we are looking forward to seeing all she accomplishes.
