Lena Ho, PhD (lead PI), is regarded as a pioneer in the field of microprotein research with over 30 primary research articles (5991 citations, H-index of 21) in top-tier journals. With more than 12 years of experience in microprotein discovery, functionalization and therapeutic development, Lena and her team have developed a framework of bioinformatic tools for mining ribo-seq data for disease-relevant small ORF peptides, as well as an extensive range of biochemical tools to validate their function and uncover their molecular mechanism. Lena is an EMBO Young Investigator and HHMI international scholar. Recent publications : 1) Coding and non-coding roles of MOCCI (C15ORF48) coordinate to regulate host inflammation and immunity.
