Profile Summary

I am a Senior Scientist with 10+ years of experience in translational R&D, spanning gene therapy, gene regulation, and developmental biology. I specialize in CRISPR/Cas9 genome editing, LNP and AAV delivery, transcriptional regulation, and preclinical development, with a proven track record of leading cross-functional programs in both academic and biotech settings. 🔎 Core Expertise: - In vivo and ex vivo gene editing using CRISPR/Cas technologies, LNPs, and AAV vectors - mRNA sequence engineering and SAR studies of modified guide RNAs - Genomic and transcriptomic analysis (RNA-seq, scRNA-seq, ChIP-seq, RNAscope) - Off-target and integration site profiling, genome editing specificity 🧬Gene Regulation & Developmental Biology: - Expertise in transcriptional control of craniofacial and cardiovascular development - NIH-funded leadership in multi-institutional research projects - Deep experience with transcription factors, enhancer activity, and GRN analysis 🧪 Preclinical & Translational Research: - Led IND-enabling studies and platform development for CRISPR-based therapeutics - Designed and executed in vivo pharmacology studies in multiple rodent models - Developed and optimized LNP formulations with superior in vivo performance - Engineered hepatic-targeted AAV vectors for gene therapy applications 🧾 Highlights: - Co-inventor on two U.S. patent applications for novel in vivo gene editing (2025) - First-author presentations at ASGCT 2024 & 2025; reviewer for peer-reviewed journals
