Go to Sequencing


We have already sequenced more than 100 different species (not counting metagenomic projects), over 1000 samples/month processed and we add about one new project every day.

Go to Library preparation

Library preparation

A key element of NGS is the high-quality library preparation. The protocols and equipment used by our team can accommodate a range of needs.

Go to Bioinformatics Analysis and Processing

Bioinformatics Analysis and Processing

Our quantitative and computational analytical unit sits at the cutting edge of bioinformatics research — we use the latest tools and develop improvements to correct short comings with these tools.

Who We Are

Established to radically improve genomic research across AgriLife, TAMU, and the Texas A&M University System

Texas A&M AgriLife Genomics and Bioinformatics Service was established thru a mission directive from Director of AgriLife Research to radically improve genomic research across AgriLife, COALS, and the Texas A&M University System, addressing a central and pressing need for access to the latest genomic technologies, and world-class laboratory and bioinformatics expertise. To meet this ambitious goal, AgriLife Research brought together a team of leading genomics, bioinformatics, molecular, and computational scientists to meet the next generation sequencing (NGS) and bioinformatics needs of the TAMU system and broader scientific community.

The new AgriLife Genomic unit received start-up funds from Texas Emerging Technology Fund as part of a larger AgriLife ETF program under the leadership of Executive Associate Director of Texas A&M AgriLife Research, Dr. Bill McCutchen.

Texas A&M AgriLife Director, Genomics and Bioinformatics The AgriLife unit is directed by Dr. Charles D. Johnson, who was recruited from the biotech industry to develop a next generation sequencing and bioinformatics program at Texas A&M. With over 20 years of scientific research and operational leadership experience, Dr. Johnson has an established track record in genomics and bioinformatics R&D. He recruited an extraordinary team of Agrilife scientists with vast and diverse background, allowing them to quickly catalyze activity across a broad spectrum of research areas, assuring a high return for each research dollar and generating significant scientific discoveries. The group has built a collaborative network of over 700 scientists spanning the entire TAMU system, along with a growing number of private sector life science and agricultural companies.

Investments in personnel and equipment have been critical to providing genomics and bioinformatics infrastructure for student training, faculty retention and successful R&D initiatives in the areas of agriculture, life sciences, human health, and veterinary medicine.
