John de Abreu

I am a detail-oriented biology researcher with experience in molecular biology, bioinformatics, systemics, field work, plant identification, DNA sequencing, data analysis, and scientific communication. I am proficient in DNA extraction, PCR, Sanger sequencing, and NGS data analysis. I have done research involving field work, wet lab procedures, and computational biology and coding. I have received both a master’s degree and a bachelor's degree in biology. I have experience with animal handling and care from my time working for a veterinarian. I have a great deal of experience with scientific communication through several research presentations and two years of running lab for students as a teaching assistant.
