Our Team
CellMosaic's scientists have extensive experience in the bioconjugation field and have authored numerous patents and papers on protein-, antibody-, sugar-, peptide-, and oligonucleotide-based bioconjugation. Additionally, we collaborate with leading industry and academic consultants to maintain a competitive edge in the bioconjugate field.
Yumei Huang, PhD — Founder, President & CEO
Dr. Huang has over 25 years of research experience in chemistry and biology, with extensive expertise in conjugation chemistry and drug development. In 2008, she founded CellMosaic to develop platform technologies for bioconjugation and drug delivery. Dr. Huang developed the core advanced conjugation processes for custom bioconjugation services and commercialized the personalized conjugation kit (PerKit™), along with many other bioconjugation-related products. She is also the sole inventor of the sugar alcohol-based AqueaTether® (AqT®) technologies, as well as other crosslinking and MS-Tag technologies, inclduing OxLink™, SxLink™, and NeIon™. Under her leadership, CellMosaic was awarded a Phase I SBIR grant from the NIH, a Breast Cancer Research Breakthrough Award from the DOD, and the 2015 Joseph R. Carter Innovation Award from MBI and MassBio. Dr. Huang holds more than 20 issued patents and patent applications worldwide and has numerous publications.
Previously, Dr. Huang worked at Johnson Matthey Pharma Services, where she developed API processes and prepared GMP materials for various clients. She also worked at Ensemble Therapeutics, where she developed core chemical technologies for a biodetection program and therapeutic development based on DNA-programmed chemistry. Additionally, she co-founded Alta Scientific Ltd., serving as Chairman and CTO from 2011 to 2012. In 2023, Dr. Huang served as a reviewer for an NIH contract grant.
Dr. Huang earned her Ph.D. in Bioorganic Chemistry from Case Western Reserve University, where her thesis under Professor Philip P. Garner focused on developing a new class of antisense drugs based on peptides and oligonucleotides. She completed her postdoctoral research under Nobel Laureate H. Gobind Khorana at MIT, focused on the roles of protein–protein interactions in signal transduction pathway. Dr. Huang also holds an M.S. in Organic Chemistry from the Graduate University of the Chinese Academy of Sciences (also known as Graduate School in Beijing, USTC) and a B.S. in Organic Chemistry from NanKai University.
Subhakar Dey, PhD — Chief Technology Officer
Subi has over 25 years of experience in chemistry, molecular biology, mass spectrometry, and the development and commercialization of clinical diagnostic assays and products. Subi joined CellMosaic in 2019 to lead the company’s various technological initiatives, including new product development, diagnostic and therapeutic applications of AqT™ technologies, and core intellectual property creation. He also oversees all technical aspects of customer projects, and contributes to the company's strategic planning, web design, and marketing strategy.
Prior to joining CellMosaic, Subi fulfilled the leadership role of Manager of IVD assay R&D at Sciex Clinical Diagnostics (Danaher Corp.), where he led the launch of the first mass spectrometry-based FDA-cleared IVD assay (Vitamin D assay). As the departmental process owner (DPO), he established standard processes for the verification and validation of IVD assays. He also played a key role in the policy deployment processes at Sciex, implementing the Danaher Business System (DBS), including Kaizen, daily management, and visual management, to streamline assay development.
Before this, Subi was a Senior Scientist at Applied Biosystems, where he worked on PNA-based single nucleotide polymorphism (SNP) detection probes. In the proteomics (LC/MS-MS) field, he developed and invented blockbuster proteomics and diagnostic reagent tags, such as iTRAQ®, Amplifex™ Keto, and Amplifex™ Diene Reagents. Subi holds more than 20 patents and has numerous publications and awards.
Subi earned a Ph.D. in Organic Chemistry from Case Western Reserve University and completed postdoctoral work in nucleic acid chemistry at Northwestern University. He holds an M.Sc. in Chemistry from the Indian Institute of Technology (IIT) Kanpur, India.
