Oklahoma State University

Assistant Professor

Espindola Camacho Andres

Espindola Camacho, Andres

Dr. Espindola also contributed to developing protocols that enhance pathogen availability in sequencing libraries, leading to increased sensitivity in detection using Target Specific Reverse Primer Pools (TASPERT).  With vast experience in analyzing genomic, transcriptomic, and metagenomic big data from both long and short-read sequencing platforms.


Dr. Espindola is currently creating computational models to predict crop productivity using the soil microbiome. He teaches Bioinformatics for Agricultural Biosecurity at both graduate and undergraduate levels and has mentored more than 30 students, including graduate and undergraduate as well as postdocs. His research program aims to develop fast protocols that can detect and predict microbial presence in sequencing samples using the latest bioinformatic methods, including data mining techniques, statistical and simulation modeling, and machine learning.
