Arkana Laboratories is a center for diagnostic pathology and research focused on one thing: improving care for patients.

We are seeking a senior scientist to conduct research in our state of the art zebrafish facility in Little Rock, AR.  The laboratory is developing zebrafish models of kidney disease and also performs contract research including toxicological testing.

To apply, please send your resume and letter of interest to


Job Title: Senior Scientist

Reports To: Director, Zebrafish labs

Status: Salary; Full-Time


Job Summary

The Zebrafish Core Program is involved in designing disease models of zebrafish, provide preclinical toxicity/efficacy evaluation and other experimental services to industry and academic institutions, as well as internal clinical staff investigators.  The scientist should be able to provide expertise in conducting, designing and troubleshooting experiments involving zebrafish. The person should have basic knowledge of the pathophysiology of diseases.


Job Duties and Responsibilities

·         Design and conduct research.

·         Evaluate facility capabilities and work with administration to identify and develop new services.

·         Performing molecular tests

·         Design Zebrafish disease models (i.e. CRISPR, gene knockouts, etc…).

·         Act as a liaison between facility scientific staff and administration.

·         Write grants (e.g. NIH, SBIR)

·         Set and track milestones of ongoing projects as well as ensure timely delivery of the projects.


Performance Requirements
