Job Description

The Hollenhorst Lab applies innovative biochemical strategies to study clinically relevant questions regarding the proteins that regulate bleeding and clotting. The goal is to further our understanding of the basic biology of hemostasis and thrombosis with an eye towards questions directly relevant to the care of patients. We are looking for an enthusiastic and motivated individual to perform experiments under the supervision of the principal investigator or senior lab member. The selected candidate will perform western blots, immunoprecipitation, protein purification, and prepare samples for mass spectrometry analysis. The individual will work with a high degree of independence, organize notebooks and manage data, and perform other laboratory experiments relevant for understanding platelets and coagulation factors. Ideal candidates will have training in wet lab techniques, strong organizational skills, and be motivated to further their career by learning and adopting new skills. While applicants from diverse backgrounds and career stages are welcome, this position is a particularly good fit for individuals who seek a 1-2 year research experience prior to applying to PhD and/or MD programs. The principal investigator will provide direct mentorship and long-term career advice. For individuals with an interest in gaining clinical experience in advance of applying to medical school, the principal investigator will provide shadowing opportunities.
