Scientist, Research Histologist

Scientist, Research Histologist 

Responsibilities 

• Perform end‑to‑end histology processing of tumor and normal tissues from mouse xenograft studies, including tissue trimming, paraffin embedding, microtomy, routine histochemical staining, immunohistochemical (IHC) on validated automated staining platforms, and archival of formalin‑fixed, paraffin‑embedded (FFPE) samples 

• Work collaboratively with in vivo scientists to provide study-aligned histology endpoints as follows: 

• Characterize new tumor models, including disseminated models of hematologic cancers and patient-derived xenografts (PDXs), and models from drug-resistant patients and conditions 

• Use IHC-based endpoints with established markers to support pharmacokinetics/pharmacodynamics (PK/PD) and efficacy studies in mouse models following therapeutic drug testing 

• Participate in general laboratory maintenance, including buffer preparation, reagent restocking, and basic equipment upkeep 

• Data documentation and reports: 

• Digitally archive slides using the Leica Aperio or similar platform 

• Accession FFPE samples into a digital specimen database and file blocks in designated storage to maintain retrievability 

• Summarize and present findings to project teams and capture complete records in an electronic laboratory notebook (ELN) in a timely manner 

Education, Qualifications, Skills and Experience 

Essential Requirements 

• BS or MS in Biology or related discipline, with at least 2 years of experience in a histopathology laboratory 

• Experience and competency in performing routine histology procedures including trimming, embedding, microtomy, and staining tissues 

• Strong organizational skills and attention to detail applied to laboratory responsibilities, data recording, and transparent reporting to project teams 

Desirable Skills/Qualifications 

• Experience developing, optimizing, and validating IHC assays, including antigen‑retrieval and titer optimization, and documentation of performance characteristics
