Michael L. Metzker, Ph.D.
An innovator for 30 years, Dr. Metzker has focused his research in three areas: next-generation sequencing (NGS) technology, sequence variation in diabetes, and HIV-1 transmission between individuals. He started his first company, LaserGen, Inc. in 2002. He has served as an Adjunct Associate Professor of Genetics at Baylor College of Medicine, and an Adjunct Associate Professor of Chemistry at Rice University.
Dr. Metzker has served as an expert witness for several HIV criminal cases, presenting a breakthrough method of phylogenetic analysis of HIV-1 DNA sequences. During his career, he has held senior-level research positions with Merck Research Laboratories and Applied Biosystems (now Thermo Fisher). He received his B.S. from the (1984) and his Ph.D. from in Houston, TX (1996).

More about Michael L. Metzker, Ph.D.
I invented the TRC technology (US Patent Application Number 15/614,958 to be issued April 12, 2022
and European patent number 17 731 374.9 granted in January 2022), have received one R43 grant
award for the detection of miRNAs using TRCs in pancreatic cancer (R43 CA200398-01A1), and will
lead this phase I proposal. Having been an innovator for 30 years, I have focused my research in three
areas: next-generation sequencing (NGS) technology development, exploration of the role of sequence
variation in diabetes, and the study of HIV-1 transmission between individuals. In addition to my
publications listed below, I am an inventor on 52 issued patents and patent applications. My interests
also include entrepreneurship, having started my first company, LaserGen, Inc. in 2002. LaserGen’s
primary focus is development of novel reversible terminators for NGS applications (see most relevant
publications). In collaboration with the scientific team at LaserGen, I developed a number of diverse,
structurally-related reversible terminators, which have led to the issuance of U.S. patents including U.S.
Patent Nos. 7,893,227; 7,897,737; 7,964,352; 8,148,503; 8,198,029; 8,361,727; 8,497,360; 8,877,905;
8,889,860; 8,969,535; 9,200,319; 9,399,798; 10,041,115; and 11,001,886. After 14 years in academia,
I have transitioned into an adjunct associate professor position at BCM to start a new corporate venture,
RedVault Biosciences. Our mission is to identify technological opportunities, provide innovative
solutions, and further advance the field of genomic medicine. Our approach differs from a traditional
business model, which takes an idea from bench to marketplace. At RedVault, our mission is to define
a need in the field, develop innovative solutions, reduce the idea to practice by demonstrating proof-ofconcept,
pursue peer-review publications of promising technological results, develop a strong
intellectual property portfolio, and identify strategic corporate partnerships that provide licensing or
acquisition opportunities for product commercialization. Our R43 grant proposes demonstrating
technical feasibility of our long template approach, see US patent application 2017-0349939 A1, with
using Illumina technology.
